a situation where adaptive experiences feel bad and non-adaptive ones feel good

How are you defining "bad" and "good", in this world whose creatures are so different from us?

I suggest: "feel good" means "have subjective properties that tend to make such creatures seek experiences that have them" and "feel bad" means "have subjective properties that tend to make such creatures avoid experiences that have them".

In which case, a world in which adaptive experiences feel worse than non-adaptive ones is a world in which creatures systematically pursue maladaptive goals and avoid adaptive ones. Evolution will get rid of such creatures pretty quickly, no?

if it is impossible, maybe that just shows that God is necessarily good.

Suppose I'm right about evolution (see above); how would you get from there to "God is necessarily good"?

entirelyuseless9y00

I basically agree with your definitions. However:

Subjective properties that tend to make a creature seek something can only do that because those subjective properties correspond to some objective physical property, at least if you aren't supporting dualism.

Why do the subjective properties that, in fact, tend to make people seek such experiences, correspond to objective properties that lead to that particular physical result (i.e. tending to physically move toward those results.)

You can say this is a tautology, and it is, in a way. But if we are simply tal... (read more)

I consider that I understand an equation when I can predict the properties of its solutions, without actually solving it.

-- Paul Dirac

[-]elharo9y290

if we want economics to be a science, we have to recognize that it is not ok for macroeconomists to hole up in separate camps, one that supports its version of the geocentric model of the solar system and another that supports the heliocentric model. As scientists, we have to hold ourselves to a standard that requires us to reach a consensus about which model is right, and then to move on to other questions.

The alternative to science is academic politics, where persistent disagreement is encouraged as a way to create distinctive sub-group identities.

--Paul Romer, NYU, "My Paper “Mathiness in the Theory of Economic Growth”

[-]James_Miller9y110

What if everyone knows that all the models are flawed, but the geocentric model makes the best predictions in one sub-domain, and the heliocentric model in another?

[-]dspeyer9y200

Then the most important question for any model would be what domains it's good at.

For example: one model approximates the population as infinite, so it gets decent predictions when the number of agents in each category exceeds five (this is rare).

These requirements to apply the model should be the first thing taught about the model.

5Good_Burning_Plastic9y

Well, if you replace "geocentric model" and "heliocentric model" with "general relativity" and "quantum field theory" that's pretty much the situation that obtains in present-day theoretical physics.

0elharo9y

In physics general relativity and quantum field theory are applied to different domains and at least one, possibly both, are widely recognized as mere approximations to the ultimate theory that subsumes them. I'll defer to Dr. Miller on this if he cares to weigh in, or any other professional economist, but my outsider's impression is that in economics as discussed by Romer the situation is more that contradictory theories are being applied to the same domain, without a serious effort to determine experimentally which (if either) is correct.

2IlyaShpitser9y

Hanson once said that testablity is not a useful notion in the social sciences. That seems kind of crazy to me, but I am not an economist.

1[anonymous]9y

Sometimes, yes. And at least one school loudly insists that they don't need no stinkin' experimental evidence, because they're actually doing a deductive formal science. In a sign of uncertain health for economics, they are considered heterodox, but not yet laughed out of polite academia.

-127chaos9y

I have no idea which one you are talking about.

-1Lumifer9y

Does it actually? Economists rarely make unhedged predictions and then rigorously test how did they turn out. Finance, though, is a sub-field that provides one with rapid and unambiguous feedback most of the time :-)

1gjm9y

Rapid, yes, but extremely noisy. If you make some decision and lose a ton of money, that doesn't mean it was a bad decision; maybe you just got unlucky.

0Lumifer9y

No, not usually, at least for common to me values of "extremely" :-) Finance does not require you to select high-variance bets :-) True, but if your actual outcomes are "extremely noisy" you need better risk management which happens to be part of finance.

1gjm9y

What's noisy is the information you get rapidly, not necessarily the outcomes. If you (stupidly, of course) buy and short-sell the same amount of some asset, your outcome is noiseless but the information you get from watching what actually happens to the asset is still noisy.

0Lumifer9y

Doesn't that entirely depend on what kind of information you are interested in?

0gjm9y

Sure. If, for instance, you decide that the information you want to get from watching your investments is the value of pi, then provided you compute it in the right way (e.g., by ignoring your investments and summing a rapidly convergent series) it won't be noisy at all. I assume you mean something distinctly less trivial than that, but I'm not sure what. I'd have thought that in a typical case the feedback you're seeking is something like "is this trading strategy I'm using a good one?" Meaning: "if I continue to use it, will I make money?". I have never worked at an investment bank or hedge fund, but my impression is that usually it takes some time before the answer to that question becomes clear, if it ever does. (The fact that the market is changing beneath your feet as you observe it doesn't make that any easier, of course.)

0Lumifer9y

Yes, that's a fair example. Nope, people who can't figure out the answer to this question fairly quickly go out of business on about the same time scale :-) How quickly actually depends on the trading strategy. One of the big advantages of high-frequency trading, for example, is that the trader will know there is something wrong with the strategy in a matter of hours. He may fine-tune it for months, but whether it works or not is clear very quickly. On the other end of the spectrum are long-term illiquid investments like private equity. In those cases it can, indeed, take years before you know whether your choices were good ones. I would say that typically a few weeks to a couple of months of losses (or a few months of neither making nor losing money) is enough to subject a trading strategy to scrutiny.

0gjm9y

Aha. I think our actual misunderstanding was about what counts as "rapid" feedback; I had in mind a shorter timescale than you did.

0Lumifer9y

Keep in mind two additional points. First, we're talking about typically complex strategies that are designed to run for a long time. Usually they accept short-term variation, but think that they'll come out ahead after the noise diversifies away. But trading ideas usually have much faster feedback cycles. For example, if you think that at the moment some asset XYZ is trading cheap because of a temporary imbalance in supply and demand and it will revert to its normal valuation in a few hours -- you'll find out if that idea was correct in a few hours. Second, the strategies I mentioned have already passed a very high bar -- they convinced a sufficient number of people that they are good enough to commit real money to. At the research stage, figuring out if a strategy looks decent takes a few minutes-- you feed it to a trading simulator based on historical data and look at the results. The strategies in the grandparent post are the equivalent of clinical trials in pharma -- there are already a lot of people convinced they would work.

1[anonymous]9y

It's also a field in which one can get "positive feedback" (ie: make a profit) by taking completely randomized actions and then just waiting for the world to reward you anyway. Most available studies show that most professional money-managers don't beat the market most of the time. On the whole, making money off macroeconomic growth doesn't yield scientific bona-fides.

0Lumifer9y

Heh. Why don't you go try it? Sounds like free money X-/ Besides, aren't you confusing finance and marketing?

0[anonymous]9y

Do you not have savings at all, or did you actually just say you've put no portion of your savings in market-tracking index funds?

1Vaniver9y

Market-tracking index funds are decidedly non-random. Lumifer's point is that you're confusing the professional money-manager's ability to make money off people who don't want to manage their own money (i.e. marketing) with the professional money-manager's ability to make money off picking individual stocks (i.e. finance), which on average does not exist. The money-management field does not represent 'free money' in that you need to actively market for clients, and there is not free money to be had in doing mediocre money management with your own money. The point that you were trying to make, that there's money to made simply by having capital and investing it in the entire economy as a whole, doesn't seem like a knock-down objection to Lumifer's point; by watching how my index fund holdings are doing, I am getting rapid and unambiguous feedback about how the overall economy is doing relative to various segments or other holdings.

-2Lumifer9y

Did I actually say? Quote me. Let me also point out three different things and note that they are different. Thing one is financial services. They are services -- they provide you with something in exchange for some sort of a fee. For example, providing an index-tracking mutual fund is a service. If you want to use this service, you pay for it and if the service is sufficiently popular, the provider makes a profit. This is not different in principle from buying the services of, say, a gardener or a car mechanic. Of course, some providers make inflated claims about their services, but that's hardly limited to finance. Thing two is investment/trading where you are trying to, basically, extract (more) money out of a market. Thing three is putting capital to work which, strictly speaking, doesn't even require markets. If you have some value and you put that value to productive use, you can expect (subject to a large number of caveats) to get some profit. This is not even finance, but basic economics. Note that in none of these cases anyone is "taking completely randomized actions" or is guaranteed a profit.

4VoiceOfRa9y

This is an example Goodhart's law. Real sciences of course ultimately reach a consensus around the truth, but trying for consensus for the sake of consensus is likely to result in a consensus around a false belief being reached.

0Lumifer9y

I think the aim is not consensus, but consistency. If two camps hold irreconcilable views, one of them is wrong and it's highly useful to know which one. The fact that both views have some domains where they seem to work better than the other is not a good excuse.

0[anonymous]9y

Unless of course you're operating in a situation best modelled by paraconsistent logic. But finding that out would require looking.

5Lumifer9y

Would you care to provide some examples along with arguments why paraconsistent logic is the best way to model them?

-3VoiceOfRa9y

Consistency with what. If you mean consistency with the truth, I agree. However, the context talks about consistency among expert positions, which is what is normally called consensus. Downvoted for introducing terminology for seemingly no purpose other than to confuse the issue. True, however, pushing for consensus or consistency will not tell you which one is wrong. Rather it will result in one of them being declared "wrong", not necessarily the one that actually is. Ok, did you mean to write this in reply to some other comment?

4Lumifer9y

Internal consistency of the science as a body of knowledge. "Consistency with the truth" is better expressed by the simple adjective "true". It's not consensus either. Consistency is a property of a theory (or a set of theories). Consensus is a property of a set of experts. No, but it will provide impetus and motivation to find out which one is wrong.

1Daniel_Burfoot9y

Romer goes on to write: He should reread Kuhn. Kuhn says that the cause of persistent disagreement is usually the lack of a relevant and workable scientific paradigm which can identify important problems, resolve disputes, and thereby mandate researchers to come to consensus. Romer's use of the phrase "the norms of science" indicates that he believes in a singular, universal, monolithic set of principles which is valid for all types of scientific inquiry. But economists obviously cannot use the same principles as physicists, simply because they cannot run experiments. What Romer is really complaining about is that there is no good paradigm for economics, but that's not anyone's fault - the discovery and articulation of a paradigm is as difficult as doing the science that the paradigm supports. A more valid criticism of the field would be "We are trying to do science without a strong enough paradigm, and the weakness of the paradigm is preventing us from resolving our disagreements definitively. Instead of trying to do more research along the same old lines, we should go back to the philosophical foundations and re-examine what it means to do economics."

0Cyan9y

This is a field in which the discoverer of the theorem that rational agents cannot disagree was given the highest possible honours...

0anna_macdonald9y

I've been wondering lately whether it is possible for economics to get a more empirical foundation. Clearly, a serious difficulty in the field is our lack of having a way for doing controlled trials. Does anyone know if anyone has tried bribing people to live in small-towns/enclaves (one to serve as control) for a time to see if we can isolate some effects at small levels that may or may not scale up? Or is this just too ridiculously impractical? (Or just too expensive?)

2Lumifer9y

That's not true. Economics (in particular, microeconomics) can and actually does do a lot of controlled trials. I don't think that's the problem. Consider psychology -- it does a LOT of controlled trials and generates a very impressive amount of garbage.

0anna_macdonald9y

Do you happen to know anywhere I can read simplified (layman-readable) results of some of these? Psychology has recently been implicated in the "can't reproduce your results" scandal, suggesting that a lot of the garbage they generate is due, more or less, to pressure to publish, bias towards confirming expectations, and insufficient safeguards. Do microeconomics trials suffer the same problems?

1Lumifer9y

In 1736 I lost one of my sons, a fine boy of four years old, by the small-pox, taken in the common way. I long regretted bitterly, and still regret that I had not given it to him by inoculation. This I mention for the sake of parents who omit that operation, on the supposition that they should never forgive themselves if a child died under it; my example showing that the regret may be the same either way, and that, therefore, the safer should be chosen.

Great quote, upvoted. On a related note, the 9/7/2015 New Yorker has a lengthy article on the Salem Witchcraft Trials. The support of the trials provided by Cotton Mather is discussed at some length. The article also talks about Mather's advocacy for smallpox inoculations. That advocacy turned out to be just as controversial as his advocacy for the witchcraft trials; it led to someone tossing a bomb into Mather's window in November, 1721. It is an interesting article and worth reading.

I became so avid a collector of instances of bad judgment that I paid no attention to boundaries between professional territories. After all, why should I search for some tiny, unimportant, hard-to-find new stupidity in my own field when some large, important, easy-to-find stupidity was just over the fence in the other fellow's professional territory?

This feels very much like a setup for saying "But I was wrong, you need experience and other background knowledge to even understand these things" or something like that. Is that the continuation in the book?

2Vaniver9y

No. Munger and Buffet both claim that a huge part of their success has simply been avoiding failures, especially of the type caused by poor rationality. Munger in particular was very taken with the same Heuristics and Biases literature that informed much of the Sequences.

4CCC9y

Surely that's precisely the sort that's most useful to find, categorise, and note down as an example to avoid later...

2Lumifer9y

I don't know about hard to find, but surely searching for large and important stupidities is more useful..?

6CCC9y

There's some usefulness to it; but the thing is, if it's an easy to find stupidity, then it's a stupidity that you already know to be a stupidity. It teaches you comparatively little about good or bad judgment. A hard-to-find stupidity is one that's subtle and difficult to recognise. It's one that is not obviously a stupidity, one that you do not easily recognise on sight. Therefore, a hard-to-find stupidity will teach you more about the difference between good and bad judgment than an easy-to-find one... Also, the importance of the stupidities is largely irrelevant to the stated goal - the importance of the consequences has little effect on how good or bad the judgment behind the decision was. (Now, if you're trying to fix stupidities, instead of learning from them, then the large, important, easy-to-find ones are the ones to look at...)

0Lumifer9y

Eh, I don't know about that. Many similar stupidities look radically different in different contexts. It's hard to overstate the effect of formulations, frameworks, and angles of view on the perception of basically the same things. I think what Charlie Munger was doing was looking for patterns which he could then discern in unexpected places. Easy-to-find vs hard -to-find is mostly a difference in context. Put Waldo into a picture of a night sky and, well...

0CCC9y

Hmmm. You are right that an easy-to-find stupidity in one case may be hard to find in another. But finding it in the easy case does not always make it all that much easier to find in the hard case - finding Waldo in a picture of the night sky does not make a Where's Waldo book any easier. ...of course, knowing what Waldo looks like does make it easier to know when you have found him.

Unless the other fellow isn't an idiot, so that "large, important, easy-to-find stupidity in the other fellow's professional territory" is correspondingly more likely to be imaginary.

"Most advances in science come when a person for one reason or another is forced to change fields" -- Peter Borden

[-]gjm9y110

That sounds clever, but is it actually anywhere near true?

I went to the Wikipedia "timeline of science" page and sampled a bunch of 20th-century advances. Maybe about 10. Not one of them had anything to do with anyone being forced to change fields.

I have no idea who Peter Borden is (nor for that matter any idea whether he actually said it: "Most quotations on the internet are made up" -- Abraham Lincoln) but I would at this point suspect him of being too ready to believe things merely because they sound good.

1hairyfigment9y

I don't think it's remotely true. Only Newton comes to mind as a possible example, and only if we accept the claim that he wouldn't have written so much about physics if he could have published his critique of the divinity of Jesus.

0Lumifer9y

It was a convenient quote, but I admit it overstates its case. A more defensible version would probably sound like "A disproportionate amount of advances in science comes from outsiders to the field". The three names which pop into my head without going to Google are Schliemann (and Calvert), Wegener, and Sokal :-)

0gjm9y

So, Schliemann and Calvert were indeed amateurs. Wegener seems to have been as much polymath as field-switcher (aside from continental drift, he worked in meteorology and astronomy). Sokal's work in mathematics and physics seems (1) not particularly, ah, boundary-transgressing and (2) not especially notable, so I guess you are referring to his foray into bullshit-hunting; that was indeed successful but I don't see that it was a major advance in science. This doesn't seem like a disproportionate amount. In fact, I would naively expect quite a lot of major advances to come from that sort of cross-fertilization, and I was rather surprised to find no field-switchers in my sample. So perhaps we can amend it to "Somewhat fewer scientific advances than one would expect come from people switching fields for any reason"?

0Lumifer9y

As I said, this was just off the top of my head without any Google assists. I suspect at least part of this idea goes back to Popper and his necessity of periodic revolutions to clear out the deadwood and establish the new base for advancing further. I don't expect that trying to make a hard fact out of my observation is going to be useful. For one, to make it at least falsifiable we'd need hard definitions of "disproportionate" and "advances", plus we're already talking of expectations, so it's going to be either a mess or a pedantic slog. If you think the observation is misleading, well, it's not the first time we disagree on fuzzy things :-)

0gjm9y

I also don't expect that trying to make a hard fact out of the observation is going to be useful; but not because some of the words in it are fuzzy, but because any halfway reasonable definition of them is going to make it flatly wrong. At any rate, I hope we can agree that the original claim in the original quotation is flatly wrong.

I am suggesting that we move too quickly to the view that rationalism is always an assault on the romantic soul, that it is a symptom of anxiety about our own madly passionate natures, or that it is a flight from love. Instead, rationalism may have its adaptive side, one that seeks to reinforce the ego structures needed to experience the passionate intensity of human emotions.

The abolition of religion as the illusory happiness of the people is the demand for their real happiness. To call on them to give up their illusions about their condition is to call on them to give up a condition that requires illusions.

I suppose Marx (if brought suitably up to date) would reply that the downside of driving some people away would be more than compensated by the upside of liberating some people from their religious delusions and thus enabling them to think more clearly about existential risk. (I've no idea whether he'd be right.) There's a comment from one of the people responsible for the Sequences ebook, arguing that it wouldn't be feasible to remove all the anti-religious material and speculating on whether re-ordering what's there might make it less of an immediate turn-off for religious readers.

2CCC9y

As a religious person myself, I have to say that's the one part of the Sequences that seems to me to be poorly fitted. (I haven't read them all, but in the ones I have read). Its inclusion seems to follow one of two patterns. The first pattern is, "all religion is false and I do not have to explain why because it is obvious". These I ignore, as they give me no information to work from. (Your use of the phrase "religious delusions" I also class under this category). The second pattern is, "I have known religious people who have fallen into this fallacy, this trap, this way of reasoning poorly, and have used it to support their claims". Again, this tells me nothing about whether or not God exists; it merely tells me that some people's arguments in favour of God's existence are flawed. It means nothing. I can give you a flawed argument for the proposition that 16/64 is equal to 1/4; the fact that my argument is flawed does not make 16/64 == 1/4 false. ...so, as far as I've so far seen, that's pretty much where things stand. The Sequences praise the virtues of clear thought, of looking at evidence before coming to a conclusion, of not writing the line at the bottom of the page until after you have written the argument on the page... and then, in this one matter, insist on giving the line at the bottom of the page and not the argument? It just gives the feeling of being tacked on, an atheist meme somehow caught up where it doesn't, strictly speaking, belong. ...maybe there's something in the parts I haven't yet read that explains this discreprency. I doubt it, because if there was I imagine it would be linked to a lot more often, but it is still possible.

9WinterShaker9y

I think (with the caveat that I've read a lot but not all of the sequences) that it is Yudkowsky's position that religions are specific manifestations of a whole cluster of more general failures of rationality, and that once someone truly internalises all of the best techniques for separating probable truths from probable untruths, it will be more-or-less impossible for that person to remain religious (unless, of course, they are sitting on a mountain of evidence in favour of the existence of one or more gods which has not been made available to the rest of us), and that it will be obvious that the specific claims of religions are false. So yes, there is not much in there that explicitly rebuts the god hypothesis, but probably the closest thing to what you are looking for is Raising the Sanity Waterline, which lists the ideas that ought to make discarding religions into one of the low-hanging fruits of any attempt at upgrading one's rationality.

-1CCC9y

The thing is, if it really was such a low-hanging fruit, then it would seem likely that the most successful scientists would have done so already (there's a lot in rationality which makes it good at science). Since the same article points out the existence of Nobel laureates who are religious in one or other way, I think it is not nearly as obvious a matter as the article suggests...

4gjm9y

Religious belief is apparently much less common * among scientists than in the general population * among very successful scientists than among scientists generally especially if one defines "religious belief" in a way that makes it have actual consequences for the observable world (e.g., a god who actually affects what happens in the world rather than just winding it up and then leaving it alone). See e.g. this summary of the results of asking scientists about their beliefs and the letter to Nature that the summary is mostly about. (Note: there's some scope for debate about the interpretation of these results, though I find the arguments at the far end of that link extremely unconvincing.) [EDITED to fix a wrong link; thanks to CCC for pointing it out.]

0CCC9y

I notice that their definition of "greater scientists" - which seems to have been what you referred to as "very successful scientists" - was "members of the National Academy of Sciences". While I have no doubt that one needs to be a pretty great scientist to become a member, the results lead me to wonder whether the membership process for joining the Academy has an atheist bias in it somewhere. I notice that the figures for scientists generally are more constant from 1914 to 1996, with approximately 60% of scientists expressing "disbelief or doubt in the existence of God" - since the selection of respondents here is not subject to the (potentially biased) membership process of a single organisation, I would give this general figure far greater credence that it shows what it purports to show. (Also, I think you may have linked the wrong page in your "scope for debate" link - it's linking to the same page as your "this summary" link)

4gjm9y

It's possible. (I suppose new members are nominated and elected by existing members, and people may tend to favour candidates who resemble themselves and be influenced by politics, religion, skin colour, etc., etc., etc.) It would need to be quite a strong bias to produce the reported results in the absence of a tendency for "greater scientists" to be less (conventionally) religious than scientists in general. The last paragraph of the Larson-Witham letter to Nature looks to me like (weak) evidence against a strong atheistic bias in the NAS, in that if there were such a bias I would expect its public utterances and those of its leaders to be a bit less conciliatory. As I say, weak evidence only. (There could also be a bias in responses; maybe atheists are more cooperative in surveys or something. I would expect any such bias to be small and it's not obvious to me which way it's more likely to go.) Yup, I did. I've linked the right one now. Sorry about that.

0CCC9y

Yes, that's the sort of thing I'm thinking of. People (in general) are usually more comfortable associating with people who share their opinions. Very weak evidence; it's easy to be conciliatory if one can also be smugly superior in pointing out how wrong the other party is (which is one possible, not necessarily correct interpretation of the last sentence of that paragraph). That is a point which I had not considered. I'm not sure which way it would go either (unless they did the survey by phoning people at their homes on a Sunday morning, when many Christians would be at church, but that would just be stupid) Ah, thanks. ...that Gallup evolution poll at the start seems quite telling. It suggests that the difference between scientists and the general public is entirely in the (much larger) rejection of young-earth creationism. This fits with my expectations (which is probably why I draw attention to it).

3gjm9y

Don't forget that at that point the atheists are all out at orgies and baby-killing parties. (Seriously: yeah, that would be stupid, and I'm pretty sure they weren't that stupid.) I don't agree with your interpretation of it. The reported numbers (no god : theistic evolution : creationism) go 55:40:5 for scientists and 9:40:46 for the general public; both the no-god and creationism options are very different between those populations. It's hard to infer anything from only three numbers per distribution, but it looks to me very much like an overall shift, with the similarity of the "theistic evolution" numbers on both sides being basically coincidence.

0CCC9y

Really? I would have expected either sleeping late or watching the rugby. Fair enough. It's only three numbers, that's consistent with thousands of possible reasons. It's not impossible. I don't see it as a spectrum, though; I see it as three entirely opposing positions. And the young-earth creationists either change their minds when becoming scientists (and since, in their minds, the concept of God is tied up with young-earth creationism, they abandon both) or fail to become scientists entirely. ...actually, now that I think of it, it should be possible to tell the difference between those two ideas, at least. Young-earth creationism is linked to geography in America, right? So if there are less scientists who grew up in in areas where young-earth creationism is more widely known, then that would imply that fewer young-earth creationists become scientists. That, in turn, would imply that my interpretation is incorrect, and there is something about becoming a scientist which makes theistic evolution also less likely than in the general population... Do you have any idea where these stats can be found?

6gjm9y

In case it wasn't obvious: I was joking. (I, for one, spend very little of my time at orgies and baby-killing parties.) I think actually both views are right. I mean, (1) there is definitely a spectrum there (there is no god - there is a god, who set up the universe and has left it alone since then - there is a god, who mostly leaves the universe alone but sometimes gets involved in subtle ways like inspiring people to do good - there is a god, who mostly leaves the universe alone but sometimes tweaks evolution a bit to arrange for the emergence of a species capable of loving relationship with him - there is a god, who made a world in which life evolves precisely so that he could steer that process in all kinds of ways, which he does - there is a god, whose influence on the variety of life on earth mostly operates through evolution but who also sometimes makes more dramatic changes - there is a god, who directly created lots of different kinds of living thing but who has let them evolve since then, which is responsible for much small-scale variation - there is a god, who created every species separately in recent history, and evolution is just a lie) but (2) the gap between theism and atheism is a particularly big one, and so is the gap between "life is old and basically has common ancestry" and "life is recent and involves lots of special creation" and (3) I'm sure quite a lot of people do flip from near one end to near the other when they change their minds about what gods, if any, exist. I worry that they'd be hard to disentangle from other things (e.g., wealthier versus poorer areas, which would affect education and what kinds of jobs people do and so forth; socially entrenched attitudes to academic learning; etc.). I'd guess that (1) there are indeed fewer, and worse, scientists from areas with a lot of young-earth creationism but (2) this doesn't really tell us much about direct influence of science on religion or vice versa, because of all those other facto

-1CCC9y

I... occasionally find humour in taking things very, very literally even when clearly intended otherwise. (That, and accidental puns. Accidental puns can be hilarious.) Alright, yes, you can create a spectrum between "there is a god, who set up the universe and has left it alone since then" and "there is a god, who created every species separately in recent history, and evolution is just a lie" - but I don't think that you can really tack "there is no god" to one end of the spectrum and consider it part of the same thing. That's like saying that there's a spectrum from "planet teeming with life" to "lifeless planet" and then sticking "planet does not exist" onto the lifeless planet end of the spectrum. ...agreed. The way I see it, people decide where on the spectrum they think the universe is. And some of them sit on the "evolution is a lie" end. And, if and when they find evidence that evolution is, in fact, not a lie, they don't generally just adjust their position on the spectrum; many of them will rather jump off the spectrum entirely, becoming atheists. ...you're probably right. A survey could be created to try to avoid these problems, but it would have to be specifically created, simply looking up old stats probably won't do it.

0Jiro9y

You can talk about a spectrum between "planet large enough for life to exist", "planet which is a little smaller which makes it a little harder for life to exist" all the way down to "no planet with no life". You can do that because in this spectrum, the extent to which the planet exists and the chance of life are connected. In the God example, the spectrum is "degree to which things can be explained without God". If you have evolution, there is one less thing that you need God to explain, and you get one step closer to not needing God to explain anything. And with nothing to need God for you can then reject the existence of God.

0CCC9y

You could do a planet-size-spectrum like that; but reversing the analogy would be - I don't know, some sort of spectrum ranging from "God doesn't exist" to "God exists"? That seems a pretty binary set of points to me - how can the state of "God 50% exists" make any sort of sense? Similarly, if nothing that you ever see requires the existence of Jim, then you can reject the existence of Jim, right?

3gjm9y

Suppose it turns out that the skeptics are mostly right about Christianity, but that there really was an itinerant preacher called Yeshua in Galilee about 2000 years ago who talked about forgiveness and love and had a reputation for casting out demons and the like; but he didn't really work any miracles, he didn't get crucified, and he certainly didn't rise from the dead. Then: Did Jesus exist? Well, kinda. Someone existed who's fairly clearly the person the gospels are about. No one existed about whom they're actually accurate accounts. Many of the most important things about "Jesus" don't apply to anyone. While it might feel a bit weird to say something like "Jesus 50% existed" in that case, I think it would give a reasonable idea of the situation.

2Lumifer9y

I don't think manipulating definitions can (or should) give rise to probability claims along the lines of "Jesus 50% existed". Jesus-the-Son-of-God and Jesus-the-itinerant-preacher are two very different people/concepts. No, they will not blend.

3gjm9y

I wouldn't want to defend the "50% existed" claim too seriously, but note that the discussion here was never really about explicit claims of that kind. It was about whether it's appropriate to consider, e.g., "there is a god who gets involved in biological evolution" intermediate between "there is no god" and "there is a god who created every kind of living thing ex nihilo". I say yes; CCC says no. The affirmative answer doesn't require, e.g., being willing to say that a god who never does anything "50% exists"; only regarding a less-active god as in some sense intermediate between a more-active god and no god.

-1CCC9y

You can definitely plot all three points on the same graph - you can even plot them such that the distance from "there is no god" to "there is a god who created every kind of living thing ex nihilo" is greater than the distance from "there is a god who gets involved in biological evolution" to either of the two aforementioned points. That can all be done perfectly sensibly. My claim is simply that the three points can't be colinear on that graph. ...I hope that makes it a bit clearer.

1gjm9y

It seems to me that you can plot them wherever you want to, so this is really a question of aesthetics more than anything else. Or is there some actual consequence that follows from one or another answer to this question?

0CCC9y

...it would be a bit like plotting 0, 1 and i colinearly. (I assume you're familiar with complex numbers?)

2gjm9y

Yes, very familiar with complex numbers, thanks. But, I repeat, you can plot what you want however you want; the question is whether it's helpful, and that will depend on the application. (Suppose the values taken by your dependent variable are all on the circle of radius 1/sqrt(2) centred at (1+i)/2. Then plotting 0, 1, and i collinearly may make a whole lot of sense, though you might actually want to call them -3pi/4, -pi/4 and pi/4 respectively.)

0CCC9y

I reluctantly concede the point, but firmly maintain that calling them -3pi/4, -pi/4 and pi/4 respectively would make a lot more sense.

0CCC9y

...I wouldn't describe that as "God 50% exists". I'd describe that as "someone with strong similarity to the biblical Jesus existed". To take an analogy, again, let us consider Dr. Joseph Bell. Dr. Bell was a medical school lecturer who emphasised the importance of close observation in making a diagnosis, and made a game of observing a stranger and deducing his occupation and recent activities. He was also the inspiration for the fictional character of Sherlock Holmes (who was famous for doing the same). Does this imply that Sherlock Holmes 50% existed? No. Sherlock Holmes 0% existed; Dr. Joseph Bell 100% existed.

0gjm9y

As I think I said somewhere else in this discussion, the way this issue arose wasn't by anyone actually claiming in so many words that "God 50% exists" is a sensible thing to say. Although I've kinda-sorta defended saying some things of that kind, I agree that it's not actually the best way to describe any state of affairs I can envisage. The actual question, IIRC, was whether it's reasonable to regard theistic evolution as intermediate between special creation and naturalistic evolution. Those are all positions that can be held by theists (though in practice not many theists embrace naturalistic evolution) and seeing them as points on a continuum really doesn't require one to endorse saying "God 50% exists" in any possible world.

0Jiro9y

The state isn't "God 50% exists" but "there is evidence which indicates that God might exist, but the evidence is 50% as good (or there is 50% as much of it) as the evidence at the far end of the spectrum". There's a continuous line from lots of evidence for God, to some evidence for God, to no evidence for God.

0CCC9y

That is a sensible axis, and you can move along it in a straight line, yes. It's just a different axis to either of the ones I was talking about.

0gjm9y

Ah, OK. Yes, I do that too. I just thought I should check :-). "No god" and "god who does nothing" are very different metaphysically but have the exact same observable consequences, and evidence for or against one will equally be evidence for or against the other. I don't see that it's obviously inadmissible to put them next to one another. Of course the more interesting notions of god are ones that do do something (even if only to create a universe according to their whims rather than according to the dictates of some "mindless" physical theory), but we've already agreed (I think) that those can be put on a spectrum that has "perfectly inactive god" on it. My perspective is a little different. They decide the following three interlinked things: (1) where the observable features of the universe lie on that spectrum, (2) what their religious position is, and (3) how the universe should look if #2 is correct. They generally decide these so that they're reasonably consistent with one another. Then if they learn new things about #1, they may change either #2 or #3 to make it match; if they change #2 they may convert or deconvert; if they change #3 they may change their theology or their ideas about physics or something.

2TheAncientGeek9y

"There is a single universe" and "we are in one branch of a multiverse, but can't access the other branches" are very different metaphysically but have the exact same observable consequences, and evidence for or against one will equally be evidence for or against the other. That's a thing about metaphysics, not a thing about theology.

0gjm9y

I agree. Were you expecting me not to? (On the other hand, if some particular believer believes in a perfectly inactive god then that is a thing about theology as well as metaphysics. Is that meant to be a problem somehow?)

0CCC9y

While I agree that there will be no observable difference, you're talking about two different axes here. One axis is "how much God does", and most of your spectrum is running along this axis. The other axis is "whether God exists", and treating that as part of the same axis is an error. (Admittedly, the axes are related - the idea of a universe where God doesn't exist yet is nonetheless active is rather absurd - but they are still not the same axis). ...the way you've phrased #3 reduces your argument to a tautology on close reading (specifically, #1 and #3 must always match regardless of #2). I think (and feel free to correct me if I'm wrong) that a better phrasing for #3 would be "how the universe should look if God exists" (instead of "...if #2 is correct"). Then, for theists, #2 would be "theist" and #1 would match #3; for atheists #2 would be "atheist" and #1 may or may not match #3. Then my view is that those who start with creationist leanings (in #1 and #3, #2 being "theist") but pursue a scientific career find, in the course of their studies, that #1 (the observable features of the universe) are not as they had thought; then #1 and #3 no longer match. #3 is complex and difficult to change without feeling like it's being changed arbitrarily (and will probably need to be changed repeatedly as #1 changes with further study); but #2 is a switch, far easier to flick, and therefore far more commonly flicked.

2gjm9y

I think we need to look back at why we're asking how many axes to use. The question was how to interpret the differences between two populations in the proportions of "special creation", "theistic evolution" and "naturalistic evolution" in their survey responses: we had something like 1:5:4 versus 4:5:1 and were trying to figure out whether what's happened is more that equivalent people in the two populations have made different choices between SC and NE, or that equivalent people in the two populations have made different choices between SC and TE, or TE and NE. Let's stipulate that the difference between "no god" and "perfectly uninvolved god" is bigger than any difference between different theistic scenarios. Would that really do much to resolve our disagreement about how to explain the survey differences? I don't think so. No, I don't think it does. It might if everyone always insisted on perfect consistency among their beliefs, but in practice most of us accept that we're wrong about some things (even though we don't know which things) and so when we find inconsistencies we don't immediately change our minds. So someone may believe, e.g., that Christianity is right, and that in the absence of compelling contrary evidence Christianity would lead to creationism, and that there is in fact such evidence and therefore one should accept evolution. And there's nothing terribly wrong with holding those views, though of course someone who does should make some effort to figure out where the mistake is. For someone in that position, #1 and #3 don't match. The same might be true for an atheist who reads a pile of creationist literature arguing that a godless universe should look very different from ours and is not currently able to refute it (either because actually creationism is right, or because they just happen not to have the relevant information and arguments at their fingertips). I don't think the god-switch (#2) is so easily flicked. My impression -- which of

0CCC9y

The size of the difference has absolutely nothing to do with my point. My point is that the difference is of an entirely different kind. To take an analogy; let us say you have a duck, and you are measuring the greyness of its feathers. This runs along a spectrum from snowy white to ebony black. There is no point on this axis where the duck is actually a swan. Both of your examples appear to me to show someone, having changed their ideas about #1, in the process of altering #2 or #3 to match. On consideration of this, I will admit that I was thinking only of the steady-state case (when someone's beliefs are internally consistent) and not really thinking about the transitional period during which they are not (even though some people might spend a majority of their lives in such a transitional state). It's not so much that it's easily flicked as that it has less moving parts; flicking it requires adjusting one thing as opposed to many things. (Of course, changing either can be difficult - the default reaction would still be to reject any unwanted evidence and/or associated arguments). ...though I could be wrong about that.

2gjm9y

The point I'm making is that actually the discussion was about the colour of the feathers, and swan-ness as such is a mere distraction. As you go on to remark, this process may never actually get as far as altering either #2 or #3 to match, and there's nothing terribly wrong with that (beyond the fact that we have unreliable information, finite brainpower, etc., all of which is simply part of the human condition). I suggest that most people's beliefs, most of the time, are not internally consistent. This is boringly true if we count it as inconsistent when someone thinks probably-P1, probably-P2, ..., probably-Pk, and P1,...,Pk can't all be true -- which doesn't have to indicate any suboptimality in belief-structure -- and less boring but surely still true if we only count it as inconsistent when someone's probability assignments (so far as they can be said to have such things) can't all be close to correct (e.g., thinking Pr(A)>=0.9, Pr(B)>=0.9, and Pr(A&B)<0.7).

0CCC9y

So, to reverse the analogy, are you saying that the spectrum is "God exists but doesn't touch evolution -> God exists and guides evolution -> God exists and created everything in the recent past", with the "God exists/doesn't exist" axis being a mere distraction? ...this does make your viewpoint a good deal less tautological.

4gjm9y

Yes, that's about it. (I guess "tough" was meant to be either "touch" or something like "work through".) It happens that most people who believe evolution operates without divine intervention or design believe that there are no gods to intervene or design in the first place, but there's no fundamental reason why a theist couldn't hold pretty much the exact same view of evolution as an atheist.

1CCC9y

"Tough" was supposed to be "touch", yes (and I've edited that correction into my previous post). This axis makes sense to me as a single axis, then. Not only is there no fundamental reason, but that's also pretty much the official position of the Vatican, who are about as theist as you get...

6gjm9y

The Vatican's official position is less than perfectly clear. Humani Generis in 1950 grudgingly accepted that Roman Catholics scientists could work on evolution, provided they didn't hold that evolution was definitely right and provided they accepted that souls are directly created by God. Then in 1996, addressing the Pontifical Academy of Sciences, JP2 accepted that evolution is "more than a hypothesis" (but do see the footnote about that phrase), but he by no means said that evolution proceeds without any divine involvement, and indeed it seems he rather conspicuously avoids saying anything that could be taken as endorsing that view.

1IlyaShpitser9y

Fnord. Believing in probabilities of 1 is bad practice here, right? ---------------------------------------- Vatican's official position on evolution is likely empirically indistinguishable from what we can see with our own eyes (e.g. the scientific view). This has old precedent, see e.g. how transubstantation is handled in Christianity.

6gjm9y

If you think there's any real question about whether it was grudging, please actually read Humani Generis (it's not very long) and come back and tell me whether you still think so. (If you mean something else, then I'm missing your point; consider explaining?) Oh yes. But, again: please by all means go and read the encyclical and then tell me whether you really think Pius XII meant anything much like that. Tell me, in particular, whether you notice any reluctance to state that points of RC doctrine are definitely right. (Spoiler: it says in so many words, e.g., that some "religious and moral truths" delivered by revelation "may be known by all men readily with a firm certainty and with freedom from all error".)

1IlyaShpitser9y

I think it's like trying to discern tone. Poe's law says this is hard in the context of sarcasm, but it seems hard in general from text. Seems doubly hard for people coming from a different background from you, the more different the more difficult the problem (xenoanthropology). People use language differently, people parse things differently (dog whistles, etc.) What do we really know about how someone whose life trajectory resulted in the Papacy uses language? But let's say you are even right. Why talk about tone at all? Are you trying to stick it to the Pope? What is the point of doing that? Why use emotionally non-neutral language?

4gjm9y

Er, no. Why would I be trying to do that? This seems like an awfully general argument against interpreting anyone's words. Encyclicals are intended to be widely read and understood. Is it really likely that some special papal quality makes them particularly difficult for others to interpret? Because the question at issue is whether the official position (on evolution) of the Vatican is indistinguishable from the naturalistic evolution commonly held by unbelieving biologists; and the relevant documents are few and ambiguous and vague; and so attempting to extract whatever nuances one can from them seems worthwhile. Humani Generis is one of the key documents for understanding the RCC's view of evolution, and it seems to me reasonable to draw different conclusions from the document as it actually is than we would from a document that was more unequivocally accepting of biological evolution.

-1IlyaShpitser9y

Well, I am not saying we should not try to interpret what people say or write. But: (a) This is hard to do for tone (Poe's law, principle of charity, etc.) (b) Meaning is a binary relation between text and interpreter, and isn't always so simple (author is dead) (c) Effective communication depends on shared cultural context and gets progressively harder as context gets less and less shared. In the limit, you get "communication is impossible" (a lot of Stanislav Lem stories are about this). ---------------------------------------- Why not be charitable, then? From the CC point of view, there is no profit in making falsifiable claims, so they will probably retreat from making them. They don't want to look stupid, and at any rate, science isn't their business.

2gjm9y

Sure. But I don't see any reason to think we're near the limit in this case. Pius XII was pope and I'm not, true enough. But we're reasonably close in time (he was born a little less than 100 years before me), from reasonably similar cultures (both Western European), of at least overlapping religious backgrounds (my family was RC and I was a Christian although not an RC for something like 30 years) -- this all seems to me like the sort of situation in which interpretation should be less problematic than usual. I really don't see that I'm being uncharitable. If you insist that I am and ask why, I suppose the answer is that in cases of conflict I'd rather be accurate than charitable; I see the PoC as (inter alia) a tool for avoiding wrongness that comes from assuming people who disagree with you are evil or stupid. But I'm not (I promise) assuming that either Pius XII or John Paul II were evil or stupid, and my real answer to your question is that I don't see how I'm failing to be charitable. There is profit (if we must put it that way) in making correct claims, and if a pope thinks that theological considerations lead to a particular empirical claim then I don't expect him to refuse to state it on those grounds. (It seems to me that expecting otherwise is the less charitable position.) And there is profit (again, if we must put it that way) in making claims that sound confident and informative rather than vague. But, as it happens, I am not (I think) claiming that the RCC's official documents make a falsifiable claim that is incompatible with naturalistic evolution. I am claiming that the position they state is deliberately less specific than naturalistic evolution; in particular, you will search in vain for any statement that evolution proceeds as if there were no god guiding it. Or that it probably does. Or, I think, even that it might do. And that the official documents give the impression (to me, at least) that their authors think it probably doesn't. I repea

2entirelyuseless9y

The closest you can get to an "official" statement on that would be in the document of the International Theological Commission "Communion and Stewerdship". That is not technically considered a teaching document but it had to be approved by Ratzinger as head of the Congregation of the Doctrine of the Faith, which at least means that he considered it acceptable. Here is #69: 1. The current scientific debate about the mechanisms at work in evolution requires theological comment insofar as it sometimes implies a misunderstanding of the nature of divine causality. Many neo-Darwinian scientists, as well as some of their critics, have concluded that, if evolution is a radically contingent materialistic process driven by natural selection and random genetic variation, then there can be no place in it for divine providential causality. A growing body of scientific critics of neo-Darwinism point to evidence of design (e.g., biological structures that exhibit specified complexity) that, in their view, cannot be explained in terms of a purely contingent process and that neo-Darwinians have ignored or misinterpreted. The nub of this currently lively disagreement involves scientific observation and generalization concerning whether the available data support inferences of design or chance, and cannot be settled by theology. But it is important to note that, according to the Catholic understanding of divine causality, true contingency in the created order is not incompatible with a purposeful divine providence. Divine causality and created causality radically differ in kind and not only in degree. Thus, even the outcome of a truly contingent natural process can nonetheless fall within God’s providential plan for creation. According to St. Thomas Aquinas: “The effect of divine providence is not only that things should happen somehow, but that they should happen either by necessity or by contingency. Therefore, whatsoever divine providence ordains to happen infallibly and of nec

You are failing to be charitable when you use fnords like "grudgingly." It's not emotionally neutral language, it conjures in the mind stupid old men blocking scientific progress for silly reasons, and getting Galileo in trouble, etc., being dragged forward, kicking and screaming by our side, the hero scientists. The CC is not playing that game. They are not very interested in empirical falsifiabilty, and I think when you say: you are misreading their culture. The CC has long ago evolved away from their doctrine getting them in trouble with science. Science will always beat them in a debate about falsifiable claims, and losing will make them lose prestige. This is what I mean by "profit." The easiest thing for the CC to do is massage doctrine to make this not happen. This is precisely what had happened. "Confident and informative" is language culture, and involves tone. How do we read confidence in text? What is informative in text? it's all based on allusions and references in the end. Would you find my papers informative? Probably not, because you don't share mathematical background with me. Do you share enough theological background with the Pope to peer review the Pope?

2gjm9y

Have you noticed that you are doing to me exactly what you accuse me of doing to the Popes P12 and JP2? I did not (so far as I can tell by introspection) write "grudgingly" in order to make people think of popes as stupid old men, or to summon up the spectre of the RCC blocking science for silly reasons, or to call Galileo to mind. I wrote it because CCC was saying that the RCC's official position on evolution is indistinguishable from that of naturalistic scientists, and I don't think it is, and the fact that the RCC's official documents talk about evolution as they do is one reason why I think so. I have to ask: Did you read what I wrote above, explaining that I am not claiming that the RCC's position on evolution makes empirical claims incompatible with the findings of science? Because you appear to me to be writing exactly as if I hadn't written that. I wonder on what basis you say that. (I work in industry as a mathematician; I have a PhD in pure mathematics from a top-rank university; reading mathematical papers that don't lie right within one's own areas of special expertise is hard work, but yes, I would expect to find your papers informative.) I'm not attempting to peer review the Pope. But yes, I think I am sufficiently familiar with Christian thinking generally and RC thinking in particular to distinguish grudging from enthusiastic acceptance of an idea in a papal encyclical. ---------------------------------------- I am puzzled by what is happening in this thread. You are normally an outstandingly intelligent and sensible fellow, but here you have * adopted what seems to me an exceptionally combative approach * apparently failed to read what I wrote (not, I think, too obscurely) * accused me of a particular kind of uncharitable reading while simultaneously applying exactly that kind of uncharity to me * confidently stated things about me ("you don't share mathematical background") for which you have no good evidence, and which are in fact prob

-1IlyaShpitser9y

I am not Catholic. I find LW attitudes about religion (and certain other things) kind of annoying, though, if you want to try to reverse engineer where I am coming from. ---------------------------------------- That's mostly what I meant, I am not trying to pull math rank (I don't think there is such a thing as math rank), merely that informativeness is a function of shared context. I am pretty happy to double down on "we don't share math background." I don't study much pure math, I doubt you study causal inference. I could study pure math, and you could study causal inference, but that's not the same thing. ---------------------------------------- Sorry, getting lost. You think RCC does make empirically distinguishable claims or not? If the former, we have a factual disagreement. If the latter, I still think it is uncharitable to inject tone reading. ---------------------------------------- I think it is bad practice to read tone. First of all, it's easy to be wrong, and second of all, it just increases room for misinterpretation of your own text. Your word grudging conjured these things in my mind. Now you could say nothing could be further from the truth as far as your intentions were concerned. But that's the thing with texts and authors. How texts come across to others (independently of what the author wanted) matter, and this is why I think injecting tone reading is so dangerous, and why academic papers are generally written in an emotionally neutral tone (to avoid these types of issues). I favor bilateral disarmament as far as tone in texts (this is probably utopian thinking on my part, as humans are all about status and social dominance when it comes to communication, and playing with tone is a big part of this, and further it is really hard to coordinate to not do that).

1gjm9y

OK, fair enough. Maybe I have too optimistic a view of how deeply I need to understand something for it to be informative to me. Would you like to point me at one of your more interesting papers so we can try the experiment? :-) I think * the RCC surely does sometimes make empirically distinguishable claims, but * I am not claiming in this discussion that it does; rather * I am saying that its position on evolution differs from that of someone who accepts a naturalistic account of evolution, because * such a person would endorse propositions that the RCC conspicuously avoids endorsing * such as "evolution proceeds in a manner that shows no sign of divine intervention or guidance". Yeah, but you demonstrably weren't only talking about your mind; otherwise you wouldn't have said 'You are failing to be charitable when you use fnord words like "grudgingly"'. (And, y'know, you could have said "it conjures in my mind ..." rather than "it conjures in the mind", if you were really only intending to say what effect those words have on you. But you weren't, really, were you?) Pardon me if I am being dim, but are you now saying that you engaged in uncharitable misreading of the tone of my writing in retaliation for my allegedly doing likewise to two popes? If not, what exactly is your point about "bilateral disarmament"? (It can't be that you did it to me because I did it to you first, because I'm pretty sure I made no comment on your tone until the grandparent of this comment, which came after your accusations against me.)

0IlyaShpitser9y

If I was speaking for someone else, I would be vulnerable to the charge of speaking for others. I am not that cognitively weird though: if this happened with me and your text, I am sure it will happen with people similar to me and texts similar to yours. My CV is online. I will mention some more things that should be done soon. But also: I would hate for you to read my stuff to prove a point, read if you are interested! But that stuff is argument about taste. RCC's insistence on "divine guidance" does not, as locals like to say, "pay rent in anticipated experience." So they can say whatever they want, it boils down to their taste about how they phrase things, not an alternative empirically testable theory. People who get angry about theism (e.g. the flying spaghetti monster sneer club) will argue with them or mock them, but they are kind of wasting their time -- there is no empirical content to the argument. So it's just a bit of culture war playing out. This entire rabbit hole would have been avoided if you didn't try to reverse engineer whether the Pope was grudging or not, and just stuck to factual reading. The point is, maybe sticking to factual reading of texts avoids a lot of time-wasting traps.

2gjm9y

I promise that I have no intention of reading your papers just to prove a point. That would be silly. I think it's eminently possible that some of them might be interesting to me. (I just looked you up in Google Scholar and grabbed the first paper it found, which I suspect is a little tangential to your main research; it was about parsing citations of scientific papers using a generative model of (part of) the citation process, allowing for errors in names etc. I think it was informative to me, though of course I may be overestimating how well I understood it. (In particular, one key element seems to be a trick you use to make your Metropolis-Hastings sampling actually generate a reasonable number of usable candidates, which is borrowed from another paper I didn't look at and where I accordingly got only a very hazy idea of what it's doing.) I don't think that's quite right. The RCC's position is carefully "unempirical" in the sense that it doesn't make any definite predictions, and that suffices to keep it from getting too badly embarrassed by future scientific discoveries. But it seems to me that, e.g., the position Pius XII laid out in Humani Generis involves somewhat different probability assignments from the position that would have been adopted by naturalist biologists at the time, and that if you had asked faithful readers of H.G. and naturalistic biologists questions like "How likely is it that in the next 50 years or so scientific investigation will find something plainly inconsistent with a purely naturalistic view of evolution?" you would have got different answers. In support of this view, here's a little extract from Humani Generis: I'm not concerned right now to argue that this is wrong (especially as it's not the latest official statement of the RCC on evolution); only that Pius XII clearly thought that divine revelation ought to shift faithful Catholics' assessment of the probability of purely naturalistic evolution -- even as regards only "the h

Not me. Would be pretty rude of me. You can ignore that citation matching paper, I was an undergrad back then. I don't work on that kind of stuff anymore. If you email me, I will send you some stuff that's paywalled.

That was my guess, FWIW. (I don't think it's necessarily rude to downvote someone you're also arguing with, if you think their arguments are really bad. But I can't recall the last time I did it, if I ever did.) Yeah, I thought the paper seemed a little far removed from the sort of thing I thought you did now (and rather tame). I'll drop you an email. If you don't get one within the next day or so, feel free to remind me; I'm very good at forgetting to do things.

Really? It comes from the link in the great=grandparent, to the text of Humani Generis.

-2entirelyuseless9y

The Catholic Church does not work the way you seem to think it does. They have made perfectly clear that polygenism is now acceptable, even without making a "new statement" in the way you that you suggest. And even Pius XII was deliberately suggesting the same thing in that very statement, by saying "it is in no way apparent" that a reconciliation is possible, rather than saying that one is not possible.

2gjm9y

Could you say more about how the RCC has "made perfectly clear that polygenism is now acceptable"? E.g., is there something in the "Communion and Stewardship" document you've quoted from a couple of times? I had a quick look and didn't find anything of the sort, but I could well have missed it. (I briefly thought "that must be a typo for not acceptable", but I'm pretty sure you did actually mean what you wrote.)

2entirelyuseless9y

Yes, I meant what I wrote. I mostly agree with what you said about Pius XII and what he was and was not cautious about. However, I am pretty sure that he deliberately left room for polygenism to be accepted in the future by saying that it wasn't clear how a reconciliation would be possible, rather than by saying that a reconciliation simply was not possible. He was pretty careful in that statement, even deliberately leaving room for aliens (by adding the clause "on this earth," because if "man" is understood as "rational animal," the existence of aliens would be the existence of other men.) People saw this even at the time and started to speculate about how "reconcilations" would be possible. While still not accepting an opinion that polygenism is definitely true, Paul VI made clear that Catholics are permitted to think that way: "In the attempt to rethink the Theology of original sin in the light of the scientific theory of evolution and polygenism, scholars have sought to determine the literary genre of the first chapters of Genesis, and in particular Gen. 1-3. And usually, following closely the documents of the Magisterium, they affirm that it is a theological aetiology, that is, a particular vision of history, a picturesque story which is largely symbolic, of an event which really happened (original sin). Consequently, they think that the bible is not concerned with the scientific question of evolution or polygenism and these are, therefore, not denied by Revelation." "Working on these premises, various hypotheses have been proposed to reconcile Revelation with science within the framework of a more modern theology of original sin. They are still only hypotheses, plausible to a greater or lesser extent, while the scientific theories are by no means certain and are in need of further completion and proof. The Magisterium of the Church in her latest documents has given clarifications of a specifically theological nature, while allowing those who are properly qu

0IlyaShpitser9y

I think the only real hard line the CC takes is on certain matters of faith when they invoke infallibility (and they only did that a handful of times on empirically unverifiable matters only). edit: I suppose actually the hard line includes some other things that form the core of the faith but needed no clarification via infallibility pronouncements, e.g. Nicene Creed. The CC will not give ground there either.

-3hairyfigment9y

A common falsehood.

0IlyaShpitser9y

Excommunication is a social punishment, a ritualized shunning, not a hill they are willing to die on. The CC is not in the business of making falsifiable claims. This policy was worked out long, long ago. ---------------------------------------- You seem pretty angry.

0CCC9y

I think a lot of that is the Vatican being really really cautious. They're ultra-cautious about just about everything they say (largely, I think, because they are well aware that (a) a lot of people will take what they say as gospel truth and (b) they don't get to take anything back, or hardly ever, so if they endorse evolution in some form and then a few decades later a scientist comes back and presents some improvement on the theory that contradicts that form then they will look silly). So, yeah. What I'm reading into that is that they're not saying it's definitely true (in the same way as they do say it's definitely true that God exists) but they are saying it looks like it just might be.

4gjm9y

As well as being ultra-cautious about evolution, Humani Generis says these things (emphasis mine): (as well as many other things that don't appear to me at all ultra-cautious, but where the language is less clear-cut). So this isn't the result of any general policy of ultra-caution. They are being extra-ultra-cautious about evolution specifically. That was in 1950, and they are less cautious now, but still very cautious. This is why I say their position is notably different from that of naturalistic evolutionary biologists. ... Oh, wait. Have I misunderstood you? If so, we may be arguing at cross-purposes. Here's our exchange from upthread: When you said "that", did you mean (1) "the exact same view of evolution as an atheist" or (2) "the idea that there's no fundamental reason why a theist couldn't, etc."? I've been assuming #1 but maybe you meant #2, in which case our disagreement is less sharp than I thought. On #2, my impression is that the Vatican hasn't said or implied much about what theists as such can reasonably believe about evolution; they're concerned, rather, with what faithful Catholics can reasonably believe about evolution; and what they've said about the latter is, inter alia, that faithful Catholics mustn't regard it as definitely right (a position that I don't think is negated by JP2's statement before the Pontifical Academy of Sciences), and from the things they are willing to call definitely right I don't think it's tenable to take this as meaning only that one shouldn't literally take Pr(evolution)=1. So I don't think the Vatican thinks it acceptable for Catholics to think about evolution in the same way as most atheists do. Again, what they think about theists more broadly is hard to tell.

2entirelyuseless9y

From the same document (of the International Theological Commission) that I quoted earlier: "Since it has been demonstrated that all living organisms on earth are genetically related, it is virtually certain that all living organisms have descended from this first organism." Given Ratzinger's approval of that document I don't think you can reasonably say that a Catholic who thinks that evolution is definitely right (in the ordinary sense of thinking that something is definitely right) is not a faithful Catholic.

0gjm9y

Well ... the very next sentence of that document is this: and while that's pretty positive about evolution it seems not to be saying that evolution is definitely right. I think what's going on here is that the authors of that document are happy being very confident about common descent but not so happy being equally confident about evolution. As to just what sort of evolution, here's an extract from further on in that document: As the section of that document that you quoted before makes clear, giving God a "truly causal role" doesn't necessarily mean endorsing divine intervention. Section 68 -- the one before the one you quoted before -- suggests what alternatives the authors had in mind, most notably the idea that he designed the universe in such a way that its natural operation would produce particular results. This, again, is quite far from any view of evolution that would be endorsed by naturalists.

2entirelyuseless9y

Even in section 68, I don't see them saying that God necessarily "designed the universe in such a way that its natural operation would produce particular results," in any sense stronger than the one which would be absolutely necessary for someone who believes that God is omnipotent and omniscient and the cause of everything that happens. In other words, given that you believe such things about God, then if you see a rock fall and land on the ground, you must believe that God wanted it on the ground. But that wouldn't necessarily imply that it would have bothered God if it landed in the water instead. Obviously naturalists would not accept God's design even in this sense. But it is not a scientific theory one way or another and makes no differences in what you expect to find in nature. So that would still allow for someone to say that naturalistic evolution is definitely true with respect to every prediction that it makes. Also, I agree that in practice, at least in other places, there is the implication that the world was designed (at least by initial conditions) for the sake of some results rather than others. This comes up especially in regard to marriage and sexuality. However, I don't see that proposed in any dogmatic way, and it seems to be wishful thinking: if it is objectively by chance that reproduction works the specific way it does, then it becomes harder or impossible to justify Catholic sexual morality. For example, if human beings had developed by evolution in such a way that sexual reproduction required one partner killing the other, it would be obviously justified for them to make technological changes in the way they reproduce.

2gjm9y

I'm not sure what sense you have in mind. It seems to me that taking seriously the idea that God is omniscient and the cause of everything that happens more or less commits one to seeing everything as designed by God to achieve whatever his purposes might be. It is fairly common to say: no, despite having that power God conferred free will upon some of his creatures, so that what they do is not chosen by him. I'm not sure that actually makes sense when looked at clearly, but in any case it seems hard to apply this idea to the laws of nature. In any case, the document we're discussing seems to me to be saying that God may guide natural processes like evolution by being a "cause of causes", and setting up the web of natural causation so as to achieve his ends. (I don't mean to imply that it's saying he did so in such a way as to predetermine everything that happens, by the way; one can imagine God setting up a world that operates at random, and optimizing for a particular probability distribution or something of the kind.)

0entirelyuseless9y

I'm not sure if we're disagreeing about anything. I'm not saying that any Church authority has said that "the process of evolution looks exactly like a naturalistic process", but that what they do say is consistent with this being true. Even assuming God had some motive for setting up things the way they are, how would that imply something in the process of evolution that doesn't look naturalistic? I certainly agree that if you say God is relevant at all, that is not something that naturalism would say. But it also doesn't seem to mean anything concrete about the process.

2gjm9y

Neither am I. I think that * in so far as the RCC has a position on the actual facts of biological evolution (as opposed to a position on what the Catholic faithful are supposed to think about them): * it seems to me fairly clearly distinguishable from any position a typical atheist evolutionist would adopt, even as regards observable questions like how likely it is that clear evidence of non-natural processes in evolution will ever turn up, though it's hard to be certain because the official documents carefully avoid being too definite on such matters, and * I bet the senior RC clergy responsible for these documents hold positions more clearly distinguishable from those of typical atheist evolutionists, even as regards etc.; but * I suspect many of them have at least a suspicion that the scientific evidence for naturalist-looking evolution is only ever going to get better, and that clear signs of any kind of divine design in natural organisms are never going to show up. * as regards the RCC's position on what the Catholic faithful are supposed to think: * I don't think they are forbidden to adopt positions that, as regards etc., are indistinguishable from those of a typical atheist evolutionist, but * those official documents seem intended to discourage them from holding such positions, and * such positions seem permitted only (I insist on saying!) grudgingly. In particular: * until recently the Catholic faithful were explicitly forbidden to adopt such positions (on account of, e.g., what Humani Generis says about not regarding evolution as definitely correct), and * I strongly suspect that if even a modest amount of credible scientific evidence pointing in the direction of "intelligent design" were to show up, the RCC would return to that sort of stance. (Not all of those things are directly related to the questions we were discussing.) Does that help?

2entirelyuseless9y

Ok. I think I agree at least mostly with this summary, although I might qualify a few points. In itself it's likely that someone who believes in God will estimate a higher probability of evidence of non-natural processes in evolution than for an atheist. But there is also the third point you mention, namely that even theists may notice that there is currently no such evidence and may suspect that there never will be any. So this might mitigate the difference in their expectations somewhat. Regarding what is grudgingly permitted or what is encouraged, I think this is less about probability assignments about the facts at issue, and more about the probability that a belief will tend to keep people in the Church or to lead to them leaving the Church. I think this is true even when the Church authorities are explicitly aware that a belief is probably false, at least in some cases. They still will not discourage that belief if it makes it more likely for someone to stay in the Church, unless there is some other motive for discouraging it (e.g. if the belief is very obviously ridiculous, they may discourage it because it could make the Church look bad.)

0CCC9y

Yes; there are some things that the Vatican is extremely certain of (e.g. the divine origin of the Christian religion). Their ultra-caution extends to everything else - a rather large category which just so happens to include evolution. I don't think they're less cautious, I just think they recognise that there's more evidence. At the very least, the fact that no-ones convincingly refuted it in the last sixty-odd years despite all the attention being paid to it counts for quite a bit. I meant that there's no reason why a theist can't hold a view of evolution that makes exactly the same predictions in all circumstances as an atheist does. Naturally, the theist's view will incorporate God as having (at the very least) set up the natural laws that permit it, while the atheist will presumably have those laws simply existing with no particular cause; but they can both agree on what those laws are. I understand that as meaning that faithful catholics shouldn't take Pr(evolution)=1. The thing is, the things that they are willing to consider as definitely right are things like the divine origin of Christianity; and as far as I understand it, they do expect faithful catholics to take Pr(Christianity has a divine origin)=1.

4gjm9y

Unfortunately, I think what you're clarifying isn't what I was asking about :-). Let P be the proposition "as far as scientifically observable consequences go, evolution behaves as if it's entirely natural and undesigned". You and I agree that a theist can consistently believe P; call this thing that we believe Q. (Perhaps you also believe P, as I do, but that's a separate question.) You made a remark about the RCC (which has spawned a discussion entirely out of proportion to the importance of that remark in anyone's arguments, but no matter!) which I interpreted as saying that the RCC's official position is P, whereas in fact perhaps you were saying that the RCC's official position is Q (or perhaps the closely related Q', which says that a good Catholic can consistently believe P). So my question was: were you saying that the RCC's position is (something like) P, or that the RCC's position is (something like) Q? I agree that HG can be read as saying faithful Catholics mustn't take Pr(evolution)=1 but must take Pr(souls)=1 (where both "evolution" and "souls" are brief abbreviations for more complicated things, of course). I suppose what I was getting at is that saying "don't take Pr(X)=1" effectively means quite different things depending on whether the community you're addressing is in the habit of taking Pr(various things)=1 or scrupulously avoids it as e.g. LW tends to for good reason; and the fact that HG firmly endorses taking some probabilities to be 1 indicates that it's in the former camp, which to me suggests that HG is saying not what an LWer would express by "don't take Pr(evolution)=1" but something more like "don't treat evolution as definitely true in the same sort of way as you treat other ordinary things as definitely true". But it's possible, as you say, that actually the position being sketched in HG would be, if written out with more care, something more like this: there are essential dogmas of RC faith, for which one must assign p=1; there are

0CCC9y

Something almost exactly like Q'. I get the impression they were hinting at something more like Pr(evolution)=0.9, which is a figure entirely unsupported by anything in the text and involves me taking a guess, but apart from that this is pretty much exactly how I read it, yes. (With the note that the only reason the RCC is specifically calling out evolution is because there's been such a brouhaha over it from the protestant churches that staying silent on the matter would have been bad politics). While there may very well be senior clergy who do think in such terms (I wouldn't know, I've never met any seriously senior clergy) this is largely why I think that something like p=0.9 is probably closer to the intended reading. (Or p=0.95, or even p=0.99) Even if so, I'm pretty sure that it wouldn't be the official Vatican position that that probability can ever be anything less than one. (Politics, again; if the Pope ever admits to that p being less than one and someone runs a headline based on it...) And if he does see such evidence, he has to consider the possibility that he is hallucinating, or being intentionally tricked by someone; if p is high enough, then it may very well be the case that any sufficiently convincing evidence will merely convince him to report to the nearest psychologist with complaints of extraordinarily detailed and persistent hallucinations.

3gjm9y

OK; then many of my earlier comments in this thread (which were essentially arguing that the RCC's position is very different from P) have been entirely not-to-the-point and have wasted everyone's time. I repent in dust and ashes. Yeah, this is roughly my reading too. (Maybe more like p=0.7 or something back in 1950 with Humani Generis.) So much the worse for the Vatican, then. (But I think you're probably right.)

0CCC9y

Something in that general order of magnitude is probably more-or-less right. ...I think we've pretty much come to agreement on these points, then.

0entirelyuseless9y

The Church has no official statements about probability one way or another. There are certainly Catholics who think that the probability of their beliefs is one (which is insane), but typically they do not hold this by saying that no possible evidence would convince them. They say, "such and such would convince me that Catholicism is false, but such and such is absolutely impossible, and I am absolutely certain that it is absolutely impossible." On the other hand there are many far more reasonable Catholics who admit that their probability is less than one, admit that there is evidence that would convince them their beliefs are false, and admit that they might later observe the evidence. The Church has never said anything against such opinions (or against the first kind of opinion). One person I know, whom pretty much everyone considers to be a devout and orthodox Catholic, told me that he would be happy with a probability of 30% (that is, he would be happy to believe with that probability, based on Pascal's wager type reasoning). I suspect that in practice his personal probability is around 50%.

2gjm9y

The discussion about probabilities was all concerning the following specific question: How should we interpret the language in, e.g., Humani Generis about how faithful Catholics are required not to hold that some things are definitely true but the RCC teaches that some other things are definitely true? For sure, no translation into LW-style probabilityese is going to reproduce the meaning exactly, but one might reasonably hope to approximate what the RC documents say in terms that make some kind of sense to rationalists.

-2entirelyuseless9y

I think you need to understand that in terms of doxastic voluntarism. The Church holds that faith is voluntary, so that people can reasonably be praised or blamed for what they believe. They may not say it explicitly about other kinds of belief, but if they are right about religious beliefs, it would probably also be true that accepting or rejecting the theory of evolution (and any other similar thing) is also voluntary. Given that account of belief, saying "you are obliged to say that this is definitely true and that this other thing is at least not definitely true," is a statement about the choices you should make. You should choose to say (according to Pius XII), "Christianity comes from God," and "Christianity definitely comes from God," but not (according to Pius XII), "The theory of evolution applied to human beings is definitely true." Because it's a question of choices, probability is not really relevant one way or another (except in the sense that the probability that something is true might be one reason that should affect whether or not you say something). That is why I gave the example of someone who estimates the chance of his beliefs being right, based on the evidence, to be about 50%. But despite that he chooses to say "this is simply true," probably based on various moral considerations. Kind of like you might want to believe your brother about something rather than saying he is lying, not because of strong evidence for that, but because it's hurtful to say "you're lying." If this account is correct, the reason you can't translate statements like that into statements resembling claims about probability is because that is simply not what they are about. Rationalists say many things which have similar moral implications, and which don't ultimately make a lot of sense apart from a similar doxastic voluntarism (e.g. "you ought to update on evidence," which implies that you can and should choose to do so), but most people don't accept an account like

2gjm9y

When I say "you ought to update on evidence" I'm fairly sure I am neither endorsing doxastic voluntarism nor making a claim about the morality of updating (or not) on evidence. Rather, I mean that if you update appropriately on evidence then your beliefs will, over time, tend to grow more accurate compared with the beliefs you would hold if you didn't update appropriately on evidence, and that this is likely to benefit whatever goals you may have. (I might add that it benefits other people for your beliefs to be accurate, so there is some moral import to whether you update on evidence, but that's not what I would mean by "ought".) Is it a pointless thing to say if we don't get to choose what we believe? Not if we have more choice about what overall strategy to use when adjusting our beliefs than we have about individual beliefs, which I think may well be the case. (As to the actual question of doxastic voluntarism, I think it's clear that it comes in degrees and that the truth isn't right at either extreme. I don't believe either of us could, right now, decide to believe that grass is pink and forthwith start doing so; but I'm pretty sure either of us could incline ourselves more toward believing (say) that Charles Dickens was born in 1834 simply by repeating "Charles Dickens was born in 1834" in a confident tone of voice fifty times. Choose another example if you happen already to have a confident opinion about whether Dickens was born in 1834.)

I am fairly sure that many rationalists do in fact make claims about updating on evidence with moral implications, even if you do not intend those implications yourself. But in any case, even your response implies a certain degree of voluntariness, if it is possible to adopt an overall strategy of adjusting our beliefs; if it were totally involuntary, we could not affect the strategy (and in fact you agree in the second part that it is not totally involuntary.) I agree that in the way people ordinarily mean it, I could not start to believe that grass is pink. But I also could not go and kill myself right now. That doesn't make not killing myself involuntary, since the reason is that I think it would be bad to kill myself. The case of the grass might be different, and it might be impossible to start to believe that in a stronger sense. In other discussion of this issue someone compared it to holding your hand in a fire until it is burned off; that might well be a physical impossibility, not just a question of thinking that it is bad. But even in the case of holding your hand in a fire, I would see that as a certain kind of desire (to pull your hand away), even if it is one that we cannot resist with our conscious desires, and the case of belief seems pretty similar. This might just be a question of how much you are willing to strain an analogy. It's not as if "belief" is a name for one objective thing in the world which is either there or not. There are a whole bunch of things, words, actions, thoughts, and feelings, and we call various patterns of these things a "belief." Some of these things are voluntary and some are not. Simply for consistency I choose to call the voluntary parts of that pattern "belief" and exclude the other parts, at least when there is competition between them. According to this way of speaking, I could choose to believe that Dickens was born in 1834, even right now, if I had a motive to do so. But that would not affect the involuntary part

Your initial puzzling definition of what you believed had two parts ("omnipotent and omniscient"). You quickly added that you attributed many other traits to God, but were less certain of them (!) and thus presumably could change them more easily. Are you saying that the whole set of claims has a common cause and they are therefore likely to go together?

-2CCC9y

Yes, that is correct. No. In the grandparent post here, I'm talking about (what I understand is) the average person's idea of God. I recognise that my conception is not average, and some debate with other people has convinced me that a lot of people have far more complicated ideas of what God is, with far more moving parts.

The basic form of the atheistic argument found in the Sequences is as follows: "The theistic hypothesis has high Kolmogorov complexity compared to the atheistic hypothesis. The absence of evidence for God is evidence for the absence of god. This in turn suggests that the large number of proponents of religion is more likely due to God being an improperly privileged hypothesis in our society rather than Less Wrong and the atheist community in general missing key pieces of evidence in favour of the theistic hypothesis." Now, you could make a counterpoint along the lines of "But what about 'insert my evidence for God here'? Doesn't that suggest the opposite, and that God IS real?" There is almost certainly some standard rebuttal to that particular piece of evidence which most of us have already previously seen. God is a very well discussed topic, and most of the points anyone will bring up have been brought up elsewhere. And so, Less Wrong as a community has for the most part elected to not entertain these sorts of arguments outside of the occasional discussion thread, if only so that we can discuss other topics without every thread becoming about religion (or politics).

0entirelyuseless9y

"There is almost certainly some standard rebuttal to that particular piece of evidence..." Evidence is not something that needs "rebuttal." There is valid evidence both for and against a claim, regardless of whether the claim is true or false.

150lbsofstorkmeat9y

That's fair. Though, I'd put my mistake less on the word "rebuttal" and more on the word "evidence." The particular examples I had in mind when writing that post were non-evidence "evidences" of God's existence like the complexity of the human eye, or fine structure of the universe. Cases where things are pointed to as being evidence despite the fact that they are just as and often more likely to exist if God doesn't exist than they would be if he did.

-1TheAncientGeek9y

yes, the debate here is well worn: the only novelty is less wrong's degree of confidence that they have right answer. Might that be what is attracting debate, as opposed to "most of us are atheists, but whatever".

-3CCC9y

I find this unconvincing. The basic theistic hypothesis is a description of an omnipotent, omniscient being; together with the probable aims and suspected intentions of such a being. The laws of physics would then derive from this. The basic atheistic hypothesis is, as far as I understand it, the laws of physics themselves, arising from nothing, simply existing. I am not convinced that the Kolmogorov complexity of the first is higher then the Kolmogorov complexity of the second. (Mind you, I haven't really compared them all that thoroughly - I could be wrong about that. But it, at the very least, is not obviously higher).

[-]hairyfigment9y110

Before seeing this I thought you rejected all priors based on Kolmogorov complexity, as that seemed like the only way to save your position. (From what you said before you've read at least some of what Eliezer wrote on the difficulty of writing an AGI program. Hopefully you've read about the way that an incautious designer could create levers which do nothing, since the human brain is inclined to underestimate its own complexity.)

While guessing is clearly risky, it seems like you're relying on the idea that a program to simulate the right kind of "omnipotent, omniscient being" would necessarily show it creating our laws of physics. Otherwise it would appear absurd to compare the complexity of the omni-being to that of physics alone. (It also sounds like you're talking about a fundamentally mental entity, not a kind of local tyrant existing within physics.) But you haven't derived any of our physics from even a more specific theistic hypothesis, nor did the many intelligent people who thought about the logical implications of God in the Middle Ages! Do you actually think they just failed to come up with QM or thermodynamics because they didn't think about God enough?

Yes, I think so. Yes, that is correct. A few seconds' googling suggests (article here) that a monk by the name of Udo of Aachen figured out the Mandelbrot set some seven hundred years before Mandelbrot did by, essentially, thinking about God. (EDIT: It turns out Udo was an April Fools' hoax from 1999. See here for details.) Mind you, simply starting from a random conception of God and attempting to derive a universe will essentially lead to a random universe. To start from the right conception of God necessarily requires some sort of observation - and I do think it is easier to derive the laws of physics from observation of the universe than it is to derive the mindset of an omniscient being (since the second seems to require first deriving the laws of physics in order to check your conclusions). ---------------------------------------- You are right. I skipped over the idea of an entirely indifferent omni-being; that case seems to have minimal probability of an afterlife (as does the atheist universe; in fact, they seem to have the same minimal probability). Showing that the benevolent case increases the probability of an afterlife is then sufficient to show that the probability of an afterlife is higher in the theistic universe than the atheistic universe (though the difference is less than one would expect from examining only the benevolent case). I also skipped the possibility of there being no death at all; I skipped this due to the observation that this is not the universe in which we live. (I could argue that the process of evolution requires death, but that raises the question of why evolution is important, and the only answer I can think of there - i.e. to create intelligent minds - seems very self-centred) I question whether it has an interest in humans specifically, or in intelligent life as a whole. (And there is at least a candidate for a high-level law of physics which mentions humans in particular - "humans have free will". It is not proven, de

The general opinion around here (which I share) is that the complexity of those is much higher than you probably think it is. "Human-level" concepts like "mercy" and "adultery" and "benevolence" and "cowardice" feel simple to us, which means that e.g. saying "God is a perfectly good being" feels like a low-complexity claim; but saying exactly what they mean is incredibly complicated, if it's possible at all. Whereas, e.g., saying "electrons obey the Dirac equation" feels really complicated to us but is actually much simpler. Of course you're at liberty to say: "No! Actually, human-level concepts really are simple, because the underlying reality of the universe is the mind of God, which entertains such concepts as easily as it does the equations of quantum physics". And maybe the relative plausibility of that position and ours ultimately depends on one's existing beliefs about gods and naturalism and so forth. I suggest that (1) the startling success of reductionist mathematics-based science in understanding, explaining and predicting the universe and (2) the total failure of teleological purpose-based thinking in the same endeavour (see e.g., the problem of evil) give good reason to prefer our position to yours. That sounds really optimistic.

-2CCC9y

That is possible. I have no idea how to specify such things in a minimum number of bits of information. This is true; yet there may be fewer human-level concepts and more laws of physics. I am still unconvinced which complexity is higher; mainly because I have absolutely no idea how to measure the complexity of either in the first place. (One can do a better job of estimating the complexity of the laws of physics because they are better known, but they are not completely known). ---------------------------------------- But let us consider what happens if you are right, and the complexity of my hypothesis is higher than the complexity of yours. Then that would form a piece of probabilistic evidence in favour of the atheist hypothesis, and the correct action to take would be to update - once - in that direction by an appropriate amount. I'm not sure what an appropriate amount is; that would depend on the ratio of the complexities (but is capped by the possibility of getting that ratio wrong). This argument does not, and can not, in itself, give anywhere near the amount of certainty implied by this statement (quoted from here): ---------------------------------------- I should also add that the existence of God does not invalidate reductionist mathematics-based thinking in any way.

3gjm9y

Well, I suppose in principle there might. But would you really want to bet that way? Yes, I completely agree. Almost, but not exactly. It makes a difference how wrong, and in which direction. One in a billion is only about 30 bits. I don't think it's at all impossible for the complexity-based calculation, if one could do it, to give a much bigger odds ratio than that. The question then is what to do about the possibility of having got the complexity-based calculation (or actually one's estimate of it) badly wrong. I'm inclined to agree that when one takes that into account it's not reasonable to use an odds ratio as large as 10^9:1. But it's not as if this complexity argument is the only reason anyone has for not believing in God. (Some people consider it the strongest reason, but "strongest" is not the same as "only".) Incidentally, I offer the following (not entirely serious) argument for pressing the boom-if-God button rather than the boom-with-small-probability button: the chances of the world being undestroyed afterwards are presumably better if God exists.

1CCC9y

Insufficient information to bet either way. Yes, that's what I meant by "capped" - if I did that calculation (somehow working out the complexities) and it told me that there was a one-in-a-billion chance, then there would be a far, far better than a one-in-a-billion chance that the calculation was wrong. Noted. If I assume that the second-strongest reason is (say) 80% as strong as the strongest reason (by which I mean, 80% as many bits of persuasiveness), the third-strongest reason is 80% as strong as that, and so on; if the strength of all this (potentially infinite) series of reasons is added together, it would come to five times as strong as the strongest reason. Thus, for a thirty-bit strength from all the reasons, the strongest reason would need a six-bit strength - it would need to be worth one in sixty-four (approximately). Of course, there's a whole lot of vague assumptions and hand-waving in here (particularly that 80% figure, which I just pulled out of nowhere) but, well, I haven't seen any reason to think it at all likely that the complexity argument is worth even three bits, never mind six. (Mind you, I can see how a reasonable and intelligent person might disagree on me about that). ...serious or not, that is a point worth considering. I'm not sure that it's true, but it could be interesting to debate.

3gjm9y

I would expect heavier tails than that. (For other questions besides that of gods, too.) I'd expect that there might be dozens of reasons providing half a bit or so. For what it's worth, I might rate it at maybe 7 bits. Whether I'm a reasonable and intelligent person isn't for me to say :-).

0CCC9y

Fair enough. That 80% figure was kindof pulled out of nowhere, really. You think the theistic explanation might be as much as a hundred times more complex? ...there may be some element of my current position biasing my estimate, but that does seem a little excessive. So far as this debate goes, my impression is that you either are both reasonable and intelligent or you're really good at faking it.

2gjm9y

No, as much as seven bits more complex. (More precisely, I think it's probably a lot more more-complex than that, but I'm quite uncertain about my estimates.) Damn, you caught me. (Seriously: I'm pretty sure that being really good at faking intelligence requires intelligence. I'm not so sure about reasonable-ness.)

0CCC9y

One bit is twice as likely. Seven bits are two-to-the-seven times as likely, which is 128 times. ...surely? I can think of a few ways to fake greater intelligence then you have. Most of them require a more intelligent accomplice, in one way or another. But yes, reasonableness is probably easier to fake.

2gjm9y

128x more unlikely but not 128x more complex; for me, at least, complexity is measured in bits rather than in number-of-possibilities. [EDITED to add: If anyone has a clue why this was downvoted, I'd be very interested. It seems so obviously innocuous that I suspect it's VoiceOfRa doing his thing again, but maybe I'm being stupid in some way I'm unable to see.]

0CCC9y

...I thought that the ratio of likeliness due to the complexity argument would be the inverse of the ratio of complexity. Thus, something twice as complex would be half as likely. Is this somehow incorrect? (I have no idea why it was downvoted)

6gjm9y

All else being equal, something that takes n bits to specify has probability proportional to 2^-n. So if hypothesis A takes 110 bits and hypothesis B takes 100, then A is about 1000x less probable. Exactly what "all else being equal" means is somewhat negotiable. * If you are using a Solomonoff prior, it means: in advance of looking at any empirical evidence at all, the probability you assign to a hypothesis should be proportional to 2^-n where n is the number of bits in a minimal computer program that specifies the hypothesis, in a language satisfying some technical conditions. Exactly how this cashes out depends on the details of the language you use, and there's no way of actually computing the numbers n in general, and there's no law that says you have to use a Solomonoff prior anyway. * More generally, whatever prior you use, there are 2^n hypotheses of length n (and if you describe them in a language satisfying those technical conditions, then they are all genuinely different and as n varies you get every computable hypothesis) so (handwave handwave) on average for large n an n-bit hypothesis has to have probability something like 2^-n. Anyway, the point is that the natural way to measure complexity is in bits, and probability varies exponentially, not linearly, with number of bits.

0CCC9y

Yes, and hypothesis A is also 1024x as complex - since it takes ten more bits to specify. ...it seems that our disagreement here is in the measure of complexity, and not the measure of probability. My measure of complexity is pretty much the inverse of probability, while you're working on a log scale by measuring it in terms of a number of bits.

1gjm9y

Yes, apparently we're using the word "complexity" differently. So, getting back to what I said that apparently surprised you: Yes, I think it is very plausible that the best theistic explanation for everything we observe around us is what I call "7 bits more complex" and you call "128x more complex" than the best non-theistic explanation; just to be clear what that means, I mean that if we could somehow write down a minimal-length complete description of what we see (compressing it via computer programs / laws of physics / etc.) subject to the constraint "must not make essential use of gods", and another subject instead to the constraint "must make essential use of gods", then my guess at the length of the second description is >= 7 bits longer than my guess at the length of the first. Actually I think the second description would have to be much longerer than that, but I'm discounting because this is confusing stuff and I'm far from certain that I'm right. And you, if I'm understanding you correctly, are objecting not so much "no, the theistic description will be simpler" as "well, maybe you're right that the nontheistic description will be simpler, but we should expect it to be simpler by less than one random ASCII character's worth of description length". Of course the real diffiulty here is that we aren't in a position to say what a minimal length theistic or nontheistic description of the universe would look like. We have a reasonable set of laws of physics that might form the core of the nontheistic description, but (1) we know the laws we have aren't quite right, (2) it seems likely that the vast bulk of the complexity needed is not in the laws but in whatever arbitrary-so-far-as-we-know boundary conditions[1] need to be added to get our universe rather than a completely different one with the same laws, and we've no idea how much information that takes or even whether it's finite. And on the theistic side we have at most a pious hope that something like "

0CCC9y

It is confusing. I'm still not even convinced that the theist's description would be longer, but my estimation is so vague and has such massively large error bars that I can't say you're wrong, even if what you're saying is surprising to me. More or less. I'm saying I would find it surprising if the existence of God made the universe significantly more complex. (In the absolutely minimal-length description, I expect it to work out shorter, but like I say above, there are massive error bars on my estimates). While I've heard this argued before, I have yet to see an idea for a world that (a) is provably better, (b) cannot be created by sufficient sustained human effort (in an "if everyone works together" kind of way) and (c) cannot be taken apart by sustained human effort into a world vaguely resembling ours (in an "if there are as many criminals and greedy people as in this world"). I'm not saying that there isn't nasty stuff in this world. I'm just not seeing a way that it can be removed without also removing things like free will. Very little, really. There's a lot of unknowns.

5gjm9y

If we get seriously into discussing arguments from evil we could be here all year :-), so I'll just make a few points and leave it. (1) Many religious believers, including (I think) the great majority of Christians, anticipate a future state in which sin and suffering and death will be no more. I'm pretty sure they see this as a good thing, whether they anticipate losing their free will to get it or not. (2) I don't know whether I can see any way to make a world with nothing nasty in it at all without losing other things we care about, but it doesn't seem difficult to envisage ways in which omnipotence in the service of perfect goodness could improve the world substantially. For instance, consider a world exactly like this one except that whenever any cell in any animal's body (human or other) gets into a state that would lead to a malignant tumour, God magically kills it. Boom, no more cancer. (And no effect at all on anyone who wouldn't otherwise be getting cancer.) For an instance of a very different kind, imagine that one day people who pray actually start getting answers. Consistently. I don't mean obliging answers to petitionary prayers, I mean communication. Suddenly anyone who prays gets a response; the responses are consistent and, for some categories of public prayer, public. There is no longer any more scope for wars about whose vision of God is right than there is for wars about whose theory of gravity is right, and anyone who tries to recruit people to blow things up in the name of God gets contradicted by a message from God himself. There might still be scope for fights between people who think it's God doing this and people who think it's a super-powerful evil being, but I don't think it's credible that this wouldn't decrease religious strife. And if you think that being badly wrong about God is a serious problem (whether just because it's bad to be wrong about important things, or because it leads to worse actions, or because it puts one in danger

0CCC9y

I've heard arguments that we've already reached that state - think about if you go back in time about two thousand years and describe modern medical technology and lifestyles. (I don't agree with those arguments, mind you, but I do think that such a future state is going to have to be something that we build, not that we are given. It's difficult to be certain. Now I'm imagining a lot of scientists studying and trying to figure out why some cells just mysteriously vanish for no good reason - and this becoming the greatest unsolved question in medical science and taking all the attention of people who might otherwise be figuring out cures for TB or various types of flu. (In this hypothetical universe, they wouldn't know about malignant tumours, of course). And if someone would otherwise develop a LOT of cancer, then Sudden Cell Vanishing Syndrome could, in itself, become a major problem... Mind, I'm not saying it's certain that universe would be worse, or even that it's probable. It's just easy to see how that universe could be worse. That would be interesting. And you raise a lot of good points - there would be a lot of positive effects. But, at the same time... I think HPMOR showed quite nicely that sometimes, having a list of instructions with regard to what to do is a good deal less valuable than being able to understand the situation, take responsibility, and do it yourself. People would still have free will, yes. But how many people would voluntarily abdicate their decision-making processes to simply do what the voice in the sky tells them to do (except the bits where it says "THINK FOR YOURSELVES")? ...this is something which I think would probably be a net benefit. But I can't be certain. ...very probably. That just means that a better world needs to be designed that can be created under the constraints of not everyone working together. It's a hard problem, but I don't think it's entirely insoluble. That is a good question. I have no good answers fo

4gjm9y

Then I suggest that you classify the people making those arguments as Very Silly and don't listen to them in future. You're welcome to think that; my point is simply that if such a thing is possible and desirable then either one can have a better world than this without abrogating free will, or else free will isn't as important as theists often claim it is when confronted with arguments from evil. (Perhaps your position is that the world could indeed be much better, but that the only way to make such a better world without abrogating free will is to have us do it gradually starting with a really bad world. I hope I will be forgiven for saying that that doesn't seem like a position anyone would adopt for reasons other than a desperate attempt to avoid the conclusion of the argument from evil.) Again, you're welcome to imagine whatever you like, but if you're suggesting that this would be a likely consequence of the scenario I proposed then I think you're quite wrong (and again wonder whether it would occur to you to imagine that if you weren't attempting to justify the existence of cancer to defend your god's reputation). Under what circumstances would they notice this? Cells die all the time. We don't have the technology to monitor every cell -- or more than a tiny fraction of cells -- in a living animal and see if it dies. We don't have the technology or the medical understanding to be able to say "huh, that cell died and I don't know why; that's really unusual". Maybe some hypothetical super-advanced medical science would be flummoxed by this, but right now I'm pretty sure no one would come close to noticing. (Also, you could combine this with my second proposal, and then what happens is that someone says "hey, God, would you mind telling us why these cells are dying?" and God says "oh, yeah, those are ones that were going wrong and would have turned into runaway growths that could kill you. I zap those just before they do. You're welcome.".) Please, think ab

-2CCC9y

...perhaps I have failed to properly convey that argument. I did not intend to say that our world now is in a state of perfection. I intended to point out that, if you were to go back in time a couple of thousand years and talk to a random person about our current society, then he would be likely to imagine it as a state of perfection. Similarly, if a random person in this era were to describe a state of perfection, then that might be a description of society a couple of thousand years from now - and the people of that time would still not consider their world in a state of perfection. In short, "perfection" may be a state that can only be approached asymptotically. We can get closer to it, but never reach it; we can labour to reduce the gap, but never fully eliminate it. You mean, just kind of starting up the universe at the point where all the major social problems have already been solved, with everyone having a full set of memories of how to keep the solutions working and what happens if you don't? ...I have little idea why the universe isn't like that (and the little idea I have is impractically speculative). The only way? No. Starting a universe at the point where the answers to society's problems are known is a possible way to do that. ...the thing is, I don't know what the goal, the purpose of the universe is. Free will is clearly a very important part of those aims - either a goal in itself, or strictly necessary in order to achieve some other goal or goals - but I'm fairly sure it's not the only one. It may be that other ways of making a better world without abrogating free will all come at the cost of some other important thing that is somehow necessary for the universe. Though this is all very speculative, and the argument is rather shaky. Okay, if the cells just die and don't vanish, then that makes it a whole lot less physics-breaking. (Alternatively, if they are simply replaced with healthy cells, then it becomes even harder to spot). ...you k

I realise that I said "I'll just make a few points and leave it" and then, er, failed to do so. And lo, this looks like it could be the beginning of a lengthy discussion of evil and theism, for which LW probably really isn't the best venue. So I'm going to ignore all the object-level issues aside from giving a couple of clarifications (see below) and make the following meta-point: You seem to be basically agreeing with my arguments and conceding that your counterproposals are shaky and speculative; my point isn't to declare victory nor to suggest you should be abandoning theism immediately :-) but just that I think this indicates that you agree with me that whether or not the world turns out to be somehow the best that omnipotence coupled with perfect wisdom and goodness can achieve, it doesn't look much like it is. In which case I don't think you can credibly make an argument of the form "the world is well explained by the hypothesis that it's a morally-optimal world, which is a nice simple hypothesis, so we should consider that highly probable". I've argued before that it's not so simple a hypothesis, but it's also a really terrible explanation for the world we actually see. The promised clarifications: 1. The reason why my cancer-zapping proposal didn't involve curing all diseases was that it's easier to see that a change is a clear improvement if it's reasonably small and simple. Curing all diseases is a really big leap, it probably makes a huge difference to typical lifespans and hence to all kinds of other things in society, it probably would get noticed which, for good or ill, could make a big difference to people's ideas about science and gods and whatnot. I would in fact expect the overall effect to be substantially more positive than that of just zapping incipient cancers, but it's more complicated and therefore less clear. I'm not trying to describe an optimal world, merely one that's clearly better than this one. 2. My point about habits and advertisin

...to be fair, I think I also deserve part of the blame for this digression. I have a tendency to run away with minor points on occasion. I agree that this is a position which can reasonably be held and for which very strong arguments can be made. Makes sense. (It does raise the question of how we would know whether or not it is already happening for an even more virulent disease...) To be fair, it wasn't just Hitler; there were a whole lot of people working under his command whose free will was also involved. And several million other people trying to help or hinder one side or the other...

2gjm9y

I think if you hypothetically let Hitler rise to power but then magically prevent him from giving orders to persecute Jews more severely than (say) requiring them to live in ghettos, you probably prevent the Holocaust without provoking a coup in which someone more viciously antisemitic takes over. Or killing him in childhood or letting his artistic career succeed better would probably suffice (maybe Germany would then have been taken over by different warmongers blaming their troubles on other groups, but is it really credible that in every such version of the world we get something as bad as Hitler?). Of course it might turn out that WW2 was terribly beneficial to the world because it led to technological advances and the Holocaust was beneficial because it led to the establishment of the state of Israel, or something. But that's an entirely different defence from the one we're discussing here, and I can't say it seems like a very credible one anyway. (If we really need those technological advances and the state of Israel, aren't there cheaper ways for omnipotence to arrange for us to get them?)

0CCC9y

I, too, think that this is extremely likely. This would show that Hitler's orders were necessary for the Holocaust, but it would not show that they were sufficient - there's probably at least a half-dozen or so people whose orders were also necessary for the Holocaust, and then of course there's a lot of ways to prevent the Holocaust by affecting more than one person in some or other manner. I doubt the political ramifications had much to do with it. The effect of thousands of people being placed in difficult moral situations and having to decide what to do might have been a factor, though; a sort of a stress testing of thousands of peoples' free will, in a way which by and large strengthens their ability to think for themselves (because they're now well aware of how bad things get when others think for them).

2gjm9y

It doesn't need to. The more ways there are to prevent the Holocaust, the more morally unimpressive not doing so becomes. Or, at least, the better the countervailing reasons need to be. Six million Jews and six million others died in the Holocaust. It is not so easy to think for yourself when you are dead. (Or: It is very easy to think for yourself when you are dead because you have then transcended the confusions and temptations of this mortal life. But I don't think anyone's going to argue seriously that the Holocaust was a good thing because the people murdered in it were thereby enabled to make better decisions post mortem. The only reason for this paragraph is to forestall complaints that the one before it assumes atheism.)

So, um... to go back along this line of argument a few posts, then... ...this means you're in agreement with what I wrote here, right? I'm not sure exactly what point you're trying to make. And several million other people hid jews in their attics; attempted (at great personal risk) to smuggle jews to safe places; helped jews across the borders; or, on the other side, hunted jews down, deciding to obey evil orders; arrested people and sent them to death camps; ran or even built said camps... and were, in one or another way, put through the wringer. I can't find the reference now, but I do seem to recall reading - somewhere - that Holocaust survivors were significantly less likely to fall victim to the Milgram experiment or similar things. (I'm not talking about the people who were killed at all.)

2gjm9y

1. The Holocaust could probably have been prevented, with no extra adverse consequences of similar severity, by an intervention that didn't interfere with more than one person's free will. 2. Therefore, a "free will" defence of (the compatibility of theism with) the world's evil needs to consider that one person's free will to be of comparable importance to all the suffering and death of the Holocaust. 3. If free will is that important, then in place of (or in addition to) the "problem of evil" we have a "problem of unfreedom"; we are all less free than we might have been, in many ways, and even if that unfreedom is only one millionth as severe as what it would have taken to stop the Holocaust, a billion people's unfreedom is like a thousand Holocausts. 4. This seems to me to be a fatal objection to this sort of "free will" theodicy. (The real problem is clearly in step 2; we all know, really, that Hitler's free will -- or that of any of the other people whose different decisions would have sufficed to prevent the Holocaust -- isn't more important than millions of horrible deaths.) I'm pretty sure the number who hid Jews in their attics, helped them escape, etc., was a lot less than six million. And, please, actually think about this for a moment. Consider (1) what the Nazis did to the Jews and (2) what some less-corrupted Germans did to help the Jews. Do you really, truly, want to suggest that #2 was a greater good than #1 was an evil? And are you seriously suggesting that the fact that a whole lot of other Germans had the glorious opportunity to exercise their free will and decide to go along with the extermination of the Jews makes this better? I think I recall reading of a Christian/atheist debate in which someone -- Richard Swinburne? -- made a similar suggestion, and his opponent -- Peter Atkins? Christopher Hitchens? -- was heard to growl "May you rot in hell". I personally think hell is too severe a punishment even for the likes of Hitler, and did even whe

0CCC9y

Oh. ...you know, a lot of what you've been saying over the past few days makes so much more sense now. In effect, you're looking for the minimum intervention to prevent the Holocaust. (And it should have been possible to do that without taking control of Hitler's actions; a sudden stroke, bolt of lightning, or well-timed meteor strike could have prevented Hitler from ever doing anything again without removing free will). Considering how much importance the universe seems to put on free will, this might be considered an even more minimal intervention (and no matter how much importance free will is assigned, one life is less than six million lives). Which leads us directly to the question of why lightning doesn't strike sufficiently evil people, preferably just before they do something sufficiently evil. To which the answer, expressed in the simplest possible form, is "I don't know". (At best, I can theorise out loud, but it's all going to end up circling back round to "I don't know" in the end). Well, if each one was helped by one person, refused help by one person, and arrested by one person, then that's eighteen million moral dilemmas being faced. (Presumably one person could face several of these dilemmas). No. I don't. I'm very sure that it's nowhere near a complete picture of all the consequences of the Holocaust, but (2) is nowhere near (1). ...and neither (2) nor (1) (nor both of them together) are a complete accounting of all the consequences of the Holocaust. I have it on good authority (from a parish priests' sermon, unfortunately he does not publish his sermons to the internet so I can't link it) that the RCC agrees with you on this point.

0Lumifer9y

That implies the "great people" approach to human history (history is shaped by actions of individual great people, not by large and diffuse economic/social/political/etc. forces) -- are you willing to accept it?

2gjm9y

I think it implies only a rather weak version of the "great people" approach: some things of historical significance are down to individual people. (Who might be "great" in some sense, but might instead simply have been in a critical place at a critical time.) And yes, I'm perfectly willing to accept that; is there a reason why you would expect me not to? Without Hitler, Germany would still have been unstable and at risk of being swayed by some sort of extremist demagogue willing to blame its troubles on Someone Else. So I'd assign a reasonable probability to something not entirely unlike the Nazi regime arising even without Hitler. It might even have had the National Socialists in charge. But their rhetoric wouldn't have been the same, their policies wouldn't have been the same, their tactics in war (if a war happened) wouldn't have been the same, and many things would accordingly have been different. The extermination of millions of Jews doesn't seem particularly inevitable, and I would guess that in (so to speak) most possible worlds in which Hitler is somehow taken out of the picture early on, there isn't anything very much like the Holocaust.

0Lumifer9y

That, of course, is not a falsifiable statement :-)

2gjm9y

It's not my fault if the nearest correct thing to the "great people" theory that actually follows from my opinions happens not to be falsifiable. (It's not even clear that strong forms of the "great people" theory are falsifiable, actually.)

-1Lumifer9y

I am not talking about faults, but if it's not falsifiable, can it be of any use?

2entirelyuseless9y

Of course an opinion can be useful without being falsifiable. "Human life as we see it is not utterly worthless and meaningless," is probably not falsifiable (how would you falsify it?), but believing it is very useful for avoiding suicide and the like.

0Lumifer9y

Opinions are not falsifiable by their nature (well, maybe by revealed preferences). But, hopefully, core approaches to the study of history (e.g. "great people" vs "impersonal forces") are more than mere opinions.

0gjm9y

Quite possibly not. Is that a problem? (The way this conversation feels to me: You claim that X follows from my opinions. I say: no, only the much weaker X' does. You then complain that X' is unfalsifiable and useless. Quite possibly, but so what? I expect everyone has beliefs from which one can deduce unfalsifiable and useless things.)

-1Lumifer9y

A recap from my side: I didn't claim that X follows from your opinions -- I asked if you subscribe to the theory. You said yes, to a weak version. I pointed out that the weak version is unfalsifiable and useless. You said "so what?" I don't think that a version of a theory that has been sufficiently diluted and hedged to be unfalsifiable and so useless can be said to be a meaningful version of a theory. It's just generic mush. I'm not trying to trap you. I was interested in whether you actually believe in the "great people" theory (homeopathic versions don't count). It now seems that you don't. That is perfectly fine.

4gjm9y

Actually, you did both: (An aside: where I come from, saying "Your opinion implies X; are you willing to accept X?" is a more adversarial move than simply saying "Your opinion implies X" since it carries at least a suggestion that maybe they believe things that imply X without accepting X, hence inconsistency or insincerity or something.) My point, in case it wasn't clear, is that the nearest thing to the "great people" theory that actually follows from anything I've said is what you are describing as "generic mush". (Perhaps next time I will be less polite and just say "No, that's bullshit, no such thing follows from anything I've said" rather than trying to find the nearest thing I can that does follow. I was hoping that you would either explain why it would be interesting if I accepted the "generic mush" or else explain why you think something stronger than the "generic mush" follows from what I wrote, and confess myself rather taken aback at the tack you have actually taken.) As to the "great people" theory: I believe that some historical events are down to the actions of individuals (who may or may not be great in any other sense) while some are much more the result of large and diffuse phenomena involving many people. That isn't a statement that has a lot of readily evaluable observable consequences, but it's the best answer I can give to the question you asked. (As I said above, I'm not sure that the "great people" theory itself, even in strong forms, actually fares any better in terms of verifiability or falsifiability.)

-2TheAncientGeek9y

Note that infinite sets can have very low informational complexity-- that's why complexity isn't a slam-dunk against MUH. Don't think of infinite entities as very large finite entities.

2gjm9y

I'm pretty sure I wasn't thinking of infinite entities as very large finite entities, nor was I claiming that infinite sets must have infinite complexity or anything of the kind. What I was claiming high complexity for is the concept of "good", not God or "perfectly good" as opposed to "merely very good".

-2TheAncientGeek9y

Wouldn't "perfectly good" be the appropriate concept here?

4gjm9y

Yes, but the point is that the "perfectly" part (1) isn't what I'm blaming for the complexity and (2) doesn't appear to me to make the complexity go away by its presence.

1TheAncientGeek9y

I don't see how you can be sure about, when there is so much disagreement about the meaning of good. Human preferences are complex because they are idiosyncratic, but why would a deity, particularly a "philosopher's god", have idiosyncratic preferences? And an omniscient deity could easily be a 100% accurate consequentialist..the difficult part of consequentialism, having reliable knowledge of the consequences, has been granted...all you need to add to omniscience is a Good Will. IOW, regarding both atheism and consequentialism as slam-dunks is a bit of a problem, because if you follow through the consequences of consequentialism, many of the arguments atheism unravel: a consequentialist deity is fully entitled to destroy two cities to save 10, that would be his version of a trolley problem.

3gjm9y

It seems to me that no set of preferences that can be specified very simply without appeal to human-level concepts is going to be close enough to what we call "good" to deserve that name. I entirely agree, but I don't see how this makes a substantial fraction of the arguments for atheism unravel; in particular, most thoughtful statements of the argument from evil say not "bad things happen, therefore no god" but "bad things happen without any sign that they are necessary to enable outweighing gains, therefore probably no god".

2Lumifer9y

Not if the deity is omnipotent.

That's debatable, at which point it is no longer a slam dunk.

"Omnipotent", "omniscient", and "being" are packing a whole shit-ton of complexity, especially "being". They're definitely packing more than a model of particle physics, since we know that all known "beings" are implemented on top of particle physics.

1Transfuturist9y

I don't think mind designs are dependent on their underlying physics. The physics is a substrate, and as long as it provides general computation, intelligence would be achievable in a configuration of that physics. The specifics of those designs may depend on how those worlds function, like how jellyfish-like minds may be different from bird-like minds, but not the common elements of induction, analysis of inputs, and selection of outputs. That would mean the simplest a priori mind would have to be computed by the simplest provision of general computation, however. An infinitely divine Turing Machine, if you will. That doesn't mean a mind is more basic than physics, though. That's an entirely separate issue. I haven't ever seen a coherent model of God in the first place, so I couldn't begin to judge the complexity of its unproposed existence. If God is a mind, then what substrate does it rest on?

-2CCC9y

We don't know that beings require particle physics - if the only animal I've ever seen is a dog, that is not proof that zebras don't exist. I'm not saying that there isn't complexity in the word "being", just that I'm not convinced that your argument in favour of there being more complexity than particle physics is good.

-3entirelyuseless9y

"Being" surely does not have more complexity than particle physics. Particles are already beings.

-1[anonymous]9y

"Being" in the sense of intelligent mind sure as hell does. Particles are not beings in that sense of the word, and that's the common sense.

150lbsofstorkmeat9y

Kolmogorov complexity is, in essence, "How many bits do you need to specify an algorithm which will output the predictions of your hypothesis?" A hypothesis which gives a universally applicable formula is of lower complexity than one which specifies each prediction individually. More simple formulas are of lower complexity than more complex formulas. And so on and so forth. The source of the high Kolmogorov complexity for the theistic hypothesis is God's intelligence. Any religious theory which involves the laws of physics arising from God has to specify the nature of that God as an algorithm which specifies God's actions in every situation with mathematical precision and without reference to any physical law which would (under this theory) later arise from God. As you can imagine, doing so would take very, very many bits to do successfully. This leads to very high complexity as a result.

-1CCC9y

If we assume that God is a free-willed agent, then that might even be impossible in a finite number of bits...

350lbsofstorkmeat9y

The number of bits required to specify an agent with free will (insofar as free will is a meaningful term when discussing a deterministic universe) is definitely finite. Very large, but finite. Which is a good thing, since Kolmogorov priors specify a prior of 0 for a hypothesis with infinite complexity and assigning a prior of 0 to a hypothesis is a Bad Thing for a variety of reasons.

4Lumifer9y

I don't understand the concept of specifying (in bits) an agent with free will.

250lbsofstorkmeat9y

The length (in bits for a program in a universal Turing machine) of the smallest algorithm which will output the same outputs as the agent if the agent were given the same inputs as the algorithm. Do note that I said "insofar as free will is a meaningful term when discussing a deterministic universe". Many definitions of free will are defined around being non-deterministic, or non-computable. Obviously you couldn't write a deterministic computer program which has those properties. But there are reasons presented on this site to think that once you pare down the definition to the basic essentials of what is really meant and stop being confused by the language used to traditionally describe free will, that you should in principle be able to have a deterministic agent who does, in fact, have free will for all meaningful purposes.

0Lumifer9y

I don't read it this way. The approach you linked to basically says that free will does not exist and is just a concept humans came up with to confuse themselves. If you accept this, then you should not use the "free will" terminology at all because there is no point to it. So I still don't understand that concept.

150lbsofstorkmeat9y

Exactly so. The only reason I'm using the free will terminology at all here is because the hypothesis under consideration (an entity with free will which resembles the Abrahamic God is responsible for the creation of our universe) was phrased in those terms. In order to evaluate the plausibility of that claim, we need a working definition of free will which is amiable to being a property of an algorithm rather than only applying to agents-in-abstract. I see no conflict between the basic notion of a divinely created universe and the framework for free will provided in the article hairyfigment links. One can easily imagine God deciding to make a universe, contemplating possible universes which They could create, using Their Godly foresight to determine what would happen in each universe and then ultimately deciding that the one we're in is the universe They would most prefer to create. There's many steps there, and many possible points of failure, but it is a hypothesis which you could, in principle, assign an objective Solomonoff prior to. (Note: This post should not be taken as saying that the theistic hypothesis is true. Only that its likelihood can successfully be evaluated. I know it is tempting to take arguments of the form "God is a hypothesis which can be considered" to mean "God should be considered" or even "God is real" due to arguments being foot soldiers and it being really tempting to decry religion as not even coherent enough to parse successfully.)

-4Lumifer9y

Would you care to demonstrate? Preferably starting with explaining how the Solomonoff prior is relevant (note that a major point in theologies of all Abrahamic religions is that God is radically different from everything else (=universe)).

550lbsofstorkmeat9y

No, I would not care to demonstrate. A proof that a solution exists is not the same thing as a procedure for obtaining a solution. And this isn't even a formal proof: it's a rough sketch of how you'd go about constructing one, informally posted in a blog's comment section as part of a pointless and unpleasant discussion of religion. If you can't follow how "It is possible-in-principle to calculate a Solomonoff prior for this hypothesis" relates to "We are dismissive of this hypothesis because it has high complexity and little evidence supporting it." I honestly can't help. This is all very technical and I don't know what you already know, so I have no idea what explanation would be helpful to close that inferential distance. And the comments section of a blog really isn't the best format. And I'm certainly not the best person to teach about this topic.

0Lumifer9y

Sure, that's fine.

And yet here we have someone talking about "free will" as if it meant something, and CCC's usage seems entirely consistent with the meaning described here.

Well, there is a lot of motivated cognition on that topic (relevant disclaimer, I'm an atheist in the conventional sense of the word) and it seems deceptively straight forward to answer (mostly by KC-dabblers), but it is in fact anything but. The non-triviality arises from technical considerations, not some philosophical obscurantism. This may be the wrong comment chain to get into it, and your grandstanding doesn't exactly signal an immediate willingness to engage in medias res, so I won't elaborate for the moment (unless you want me to).

3Transfuturist9y

The laws of physics as we know them are very simple, and we believe that they may actually be even simpler. Meanwhile, a mind existing outside of physics is somehow a more consistent and simple explanation than humans having hardware in the brain that promotes hypotheses involving human-like agents behind everything, which explains away every religion ever? Minds are not simpler than physics. This is not a technical controversy.

2[anonymous]9y

Go on and elaborate, but unless you can show some very thorough technical considerations, I just don't see how you're able to claim a mind has low Kolmogorov complexity.

0Kawoomba9y

"Mind" is a high level concept, on a base level it is just a subset of specific physical structures. The precise arrangement of water molecules in a waterfall, over time, matches if not dwarves the KC of a mind. That is, if you wanted to recreate precisely this or that waterfall as it precisely happened (with the orientation of each water molecule preserved with high fidelity), the strict computational complexity would be way higher than for a comparatively more ordered and static mind. The data doesn't care what importance you ascribe to it. It's not as if, say, "power", automatically comes with "hard to describe computationally". On the contrary, allowing for a function to do arbitrary code changes is easier to implement that defining precise power limitations (see constraining an AI's utility function). Then there's the sheer number of mind-phenomena, are you suggesting adding one by necessity increases complexity? In fact, removing one can increase it as well: If I were to describe a reality in which ceteris is paribus, with the exception of your mind not actually being a mind, then by removing a mind I would have increased overall complexity. Not even taking into account that there are plenty of mind-templates around already (implicitly, since KC, even though uncomputable, is optimal), and that for complexity considerations, adding another of a template isn't even adding much, necessarily (I'm aware that adding just a few bits already comes with a steep penalty, this comment isn't meant to be exhaustive). See also the alphabet example further on. Then there's the illusion that somehow our universe is of low complexity just because the physical laws governing the transition between time-steps are simple. That is mistaken. If we just look at the laws, and start with a big bang that is not precisely informationally described, we get a multiverse host of possible universes with our universe not in the beginning, which goes counter the KC demands.

For the avoidance of doubt, I was putting that in the mouth of Hypothetical Modern-Day Karl Marx rather than expressing my own attitude to religion. (In case you care: I am an atheist; my wife is an active Christian; I firmly disagree with all the religions I know enough about to have an opinion but don't think words like "delusion" are generally helpful for describing them.) As for the use of religion in the Sequences, I think what's going on is this: * Eliezer thinks it's really obvious, when one thinks clearly, that the usual religions are wrong. * He expects most of his readers to agree and have similar reasons. * On the other hand, there are plenty of religious people about, some of whom are very smart. * So he uses religion as an example of something that convinces lots of people despite being very wrong. * Of course some of his readers will disagree, but he anticipates less disagreement on religion than on other topics where he sees widespread wrongness. * He doesn't spend time arguing against religion because (1) he expects most people who remain religious despite exposure to hardcore rational thinking to be basically unpersuadable and (2) discussions of religion have a way of taking over (a bit like discussions of hot-button political issues) and he didn't want everyone engaged in religious flamewars rather than discussions of other things. That all seems reasonable (whether or not correct) to me.

2CCC9y

...ah. I completely misconstrued your intentions there. My apologies. I think you are very probably correct, or close to correct. Unfortunately, it seems to have had the effect of turning atheism into something of an applause light in the comments.

5Richard_Kennaway9y

Is this an instance of the template "As someone who believes X, I have to say that where this book argues against X is its weakest part."?

3gjm9y

Obviously it is. The more interesting question is whether, as with many instances of that template, CCC thinks the anti-religious material is weakest only because it conflicts with CCC's opinions. (Those of us who think religion is Bad and Wrong are of course at the same risk of overrating them as CCC is of underrating them.)

1CCC9y

Yes, it probably is :) However, I do think that I can provide an objective argument for it being poorly fitted. That argument is as follows; it is an important part of the Sequences that one should never write the conclusion to an argument before writing down the argument that leads to that conclusion (the last line on the page should not be written first). Yet, in the particular case of atheism, we are shown only the last line, and not the supporting argument(s). Hence, poorly fitted to the Sequences as a whole.

2raydora9y

What can you predict with the existence of your God that you can't predict without? And what makes your God more likely than any other God or Gods? I suppose it's a question of granularity. While there have been a number of sound arguments for 16/64 equalling 1/4, there are hitherto no arguments of equal strength for the existence of any particular deity. 16/64 being equal to 1/4 allows people to predict what will happen when they scale objects.

1CCC9y

The existence of an afterlife. The presence of free will. I start with the question, "Is there a God?", by which I mean a being both omnipotent and omniscient. I am confident that the answer to that question is "yes". I have since assigned a number of further ideas to this concept, some of which are almost certainly wrong (but I'm not sure which ones). It is highly likely that someone else has come up with a more accurate idea of God than my idea. (There are seven billion people on Earth; the odds of my idea being the most accurate are laughably small). ...does that answer your question?

2hairyfigment9y

So, I can't help but note that the existence of an afterlife does not follow from "a being both omnipotent and omniscient." ("Free will" does not seem terribly well defined, but "possibility and could-ness" in the sense of that post does not follow either - save perhaps for the omni-being, and then only in a more general sense.) What can you predict with the part you expressed confidence in? What makes you confident?

-2CCC9y

Ah. The presence of an omniscient, omnipotent being is important to the proof, but it is not the only element in that proof (the other elements are taken from observation of the universe, and are less controversial). Consider; if an omnipotent, omniscient being exists, then it must take one of three stances with regard to humanity. It must either support the existence of humanity, or it must be neutral towards humanity, or it must support the non-existence of humanity. Since the being is omnipotent, if God wanted to wipe out humanity, God could (one or two well-placed asteroids a couple of million years back would have done it easily). Thus, I conclude that God is either in support of, or neutral towards humanity. Now I also observe the universe around me, looking for traces of maliciousness in the laws of physics. So far, I have not found any. This implies that God is not into casual, petty cruelty without reason. It seems therefore likely that God is, at the very least, not evil. The complete cessation of an intelligence would seem to be a great evil. Therefore, I postulate that there is a very strong probability that God has put some measures in place to prevent this. The measure most likely is some sort of afterlife; somewhere that a person can continue to survive, but not communicate back to those they leave behind. Of course, this argument does not say that an afterlife is certain, given the existence of God, merely that it seems likely. ---------------------------------------- As to free will; here, I note that humans are demonstrably capable of the sort of casual cruelty that is absent from the laws of nature. Moreover, humans are capable of opposing each other. This strongly implies that at least some humans are capable of opposing what God wants. (This does not necessarily imply that said opposition has any chance of long-term success). This, in turn, seems to imply that humans do have some capacity to decide for themselves; hence, free will.

6gjm9y

If the absence of maliciousness in the laws of physics is good evidence that God is not evil, is the absence of benevolence in the laws of physics good evidence that God is not good?

0entirelyuseless9y

There is at least one thing in the laws of physics that seems like benevolence rather than the absence of it. When animals have a strong tendency to do certain things, e.g. eat or engage in sex, those things tend to be pleasant to the animal. That seems like benevolence. I could imagine a situation where everything that animals tended to do, was painful to them. You might say that is absurd, since then they would not tend to do those things. But they do those things because of the laws of physics, not because of how they feel. So there is nothing absurd about it, just like a person can be on a rollercoaster without any control over what is happening. It would be pretty terrible if life was like that, but fortunately it's not.

The dog could act in ways that you interpret as the dog being pleased, but trying to interpret it that way here would be circular reasoning since you are trying to show that the dog's actions show that things are pleasant to it.

What are you claiming -- that a dog is inherently unable to have "pleasant" feelings, or that humans have no capability whatsoever to judge the what's happening in the mind of a dog on the basis of its behaviour?

2Jiro9y

In this context, you are claiming that "when animals have a strong tendency to do certain things, those things tend to be pleasant to the animal". Judging what is happening in the mind of the animal on the basis of its behavior, in order to support this claim, is circular reasoning.

Nope, that's not me, that's entirelyuseless. But you haven't answered my question.

3gjm9y

That isn't in the laws of physics, except in the trivial sense in which everything that happens in the world is "in the laws of physics" (in which case of course there are vastly many benevolent and malicious things "in the laws of physics"). I think there's a false dichotomy there. They do those things because of how they feel, and they feel the way they do because of the laws of physics. (Note that if you deny the latter half of this then you definitely aren't entitled to say that this is "in the laws of physics".)

0entirelyuseless9y

I agree that in the normal sense, they do those things because of how they feel, and that they feel the way they do because of the laws of physics. That's kind of my point. When I said, "They do those things because of the laws of physics, not because of how they feel," I meant this: I can imagine laws of physics that would imply that they do more or less the same things they do now, but they constantly feel bad about it. This is not something that might be impossible, like a zombie hypothesis. It is certainly possible, as is evident from the rollercoaster example. In other words, the question is why the laws of physics and the way people feel are related in the way that they are, instead of a different way which would be much worse. I don't see any strong argument that the actual way is intrinsically much more probable. And even if we showed that it is intrinsically more probable, someone could simply say that this shows that God is intrinsically good.

2gjm9y

I see a very strong argument that the actual way is much more probable. What does it mean to say that something feels bad? Mostly, I think, that whoever (or whatever) it feels bad to is strongly motivated to make it not happen. That's what feeling-bad is for, evolutionarily; it's what distinguishes those feelings as bad ones. So of course we should expect that people (and other animals) tend to do things that feel better in preference to things that feel worse. (You might argue that the overall level of good-feeling is higher than we'd expect. But I don't see any reason to think that.)

0entirelyuseless9y

As I said, I think there's an argument there for the goodness of God (or at least of the goodness of the universe) even if this relationship is intrinsically probable or even necessary. This is probably another way of putting the same thing: do you think that overall it is good to exist? If the universe overall is neutral, the overall expectation would seem to be that it would be neutral to exist. But most people think it is good to exist. That suggests that overall the universe is good.

0hairyfigment9y

We just had someone argue that in practice they don't (speaking of evolution). I don't wholly endorse the argument, but let's not casually dismiss it - the point that people need something to live for seems true enough.

2entirelyuseless9y

That post was not arguing that people think that overall it is bad to exist. It was arguing that people don't think it is good to exist forever, which is quite different.

-1hairyfigment9y

Balderdash. The link argues that people do not want to keep living for even a matter of millenia if they "have nothing to live for," in the author's own words (and he argues that most people only care about having/raising children, which they lose interest in). This is clearly evidence for people being indifferent between existence and non-existence without a goal, or "neutral" as you put it before you somehow forgot that alternative.

0entirelyuseless9y

That would still mean that existence was overall good for them by giving them the possibility of raising children (or reaching other goals they might have), which they would not have otherwise.

0gjm9y

I don't see how such an argument would work, as I've said in another comment. Perhaps explain there if you feel like it?

2Gram_Stone9y

Physics seems like a weirdly low-level thing if we're thinking about whether or not animals' behavior could remain the same and their subjective experience could be a state of what we would call suffering in some possible world. I just don't think that you could make edits on that level and have changes that are so fine-tuned. Editing physics doesn't leave everything alone except subjective experience; editing physics breaks fire. And if we have to settle for a physics that leaves at least most everything the same and life remains possible, then why wouldn't we expect reward mechanisms to evolve and for the default state of affairs to be one in which adaptive experiences 'feel good' and others 'feel bad'? gjm called this a false dichotomy, but I think a better though perhaps more complex way of putting it is that you're mixing up your multi-level maps. Take free will and determinism as an example. Some people become fatalists because they think that determinism contradicts their idea of what possibility means. But they're contaminating their maps. You have a low-level map of physics where everything is lawful and there is no thing similar to what you might call 'possibility.' Then you have a high-level map of decision-making, and the fatalists take the lawfulness from their low-level physics map and draw it onto their high-level decision-making map, and say, "Well, the lawfulness overrules the possibility", and then they start making null decisions, but that's wrong. Possibility is a primitive notion in your high-level decision-making map and only in that map, just like the laws of physics are primitive notions in your low-level physics map and only in that map. In the territory, your brain runs on physics and your decision-making algorithm runs on physics, and your decision-making algorithm computing the output of logical nodes making decisions other than the one that it must make makes you feel possibility, and the whole process is lawful, and you have a bridge

0entirelyuseless9y

I agree with you about compatabilism, but I don't think that answers my question. I am not saying that you could have physical situation exactly like the real world except with subjective experience reversed. I agree that in order to reverse subjective experience, you would need to make physical changes. But with those physical changes, why couldn't you have a situation where adaptive experiences feel bad and non-adaptive ones feel good? Maybe this is impossible. But if it is impossible, maybe that just shows that God is necessarily good.

2gjm9y

How are you defining "bad" and "good", in this world whose creatures are so different from us? I suggest: "feel good" means "have subjective properties that tend to make such creatures seek experiences that have them" and "feel bad" means "have subjective properties that tend to make such creatures avoid experiences that have them". In which case, a world in which adaptive experiences feel worse than non-adaptive ones is a world in which creatures systematically pursue maladaptive goals and avoid adaptive ones. Evolution will get rid of such creatures pretty quickly, no? Suppose I'm right about evolution (see above); how would you get from there to "God is necessarily good"?

0entirelyuseless9y

I basically agree with your definitions. However: Subjective properties that tend to make a creature seek something can only do that because those subjective properties correspond to some objective physical property, at least if you aren't supporting dualism. Why do the subjective properties that, in fact, tend to make people seek such experiences, correspond to objective properties that lead to that particular physical result (i.e. tending to physically move toward those results.) You can say this is a tautology, and it is, in a way. But if we are simply talking about the particular subjective property in itself (as opposed to the fact that we happen to be pointing to it using our tendency to seek it), it is not a tautology, even if it may be a physical necessity. In other words: zombies are probably physically impossible. But if they were possible, and if they were actual, instead of real humans, then reality would be neutral, neither good nor evil, since there would be no experience. In a similar way, negative-humans (who tend to seek painful experiences and avoid pleasant ones) are likely physically impossible. But if they were possible and actual, then the universe would be evil, and nearly all experiences would be bad. But as it is, most experiences are good, and the universe is good. Talking about God here is probably a distraction, but if the universe is good, then its cause or causes should also be good. If the facts that make the universe good are necessary, then its causes are necessarily good.

1Gram_Stone9y

Actually, you're affirming the consequent. If the cause of the universe is good, then the universe will be good. But if we observe that the universe is good, then we cannot infer that the cause of the universe is necessarily good. Classic example:

0entirelyuseless9y

Affirming the consequent is valid in the terms of the evidence relation. In other words, the fact that I have a sore throat is evidence that I have the flu, although not proof. In the same way, the universe being good is evidence that the cause is good. If up to that point, we assumed that the cause was entirely neutral, our best estimate will now be that the cause is good.

0Gram_Stone9y

That's true, but there are other equally explanatory hypotheses that don't involve good causes, so at the very least, the fact that the universe is good (although I would contest or at least qualify that claim) is not evidence either way. It doesn't help you figure out which possible world you're in.

0gjm9y

I suggest that things coming out of evolutionary biology are more like logical than physical necessities; we would expect the same sort of dynamics to apply even with very different physical laws. (On the other hand, the "necessity" involved is weaker, because evolution is a stochastic process and it's very possible for suboptimal bits of design to get fixed in a population.) So, anyway, the situation seems to be something like this: Any organisms with anything we could reasonably identify as "feeling good" or "feeling bad" experiences will tend to seek the ones that "feel good" in preference to the ones that "feel bad", almost tautologously. This means that, doing whatever they do, they will tend to "feel better" than we can imagine them doing if (e.g.) they absurdly sought out "feeling bad" experiences in preference to "feeling good" ones. So far, so good. But to describe this by saying that "most experiences are good, and the universe is good" seems wrong to me, and I don't see how you get from "the facts that make the universe good are necessary" to "its causes are necessarily good". To expand on those points: First: yes, living things will do nicer things in preference to nastier. But those are comparative terms. If everything in (say) human experience were made substantially more or substantially less pleasant uniformly it would have little impact on our decisions, but surely it could change whether "most experiences are good". My actual impression is that most experiences are neutral and the amounts of good and bad aren't terribly different. We have both orgasms and headaches; both enlightenment and boredom; both the satisfaction of a job well done and the frustration of failing to achieve what we should. I don't see any reason to think other animals' balance is very different. Second: if "the universe is good" is meant to be just another way of saying "most experience is good" then I don't think passing from one to the other does anything other than invi

0entirelyuseless9y

I think I disagree with the first part (that we can't understand the idea of something doing things that feel bad rather than feel good, or that there are obvious reasons why this is impossible in principle), but I won't argue that for two reasons. First because that would probably end up being a very time consuming discussion, and second because, as I said, I think I can make my argument even if I grant your point. Regarding your three points: 1. It sounds like you are saying that there is a balance of good and evil in human life which is basically equal, so that overall life is neutral. If this is the case, it would certainly make sense to say that the universe is neutral as well. But I disagree that the overall balance is neutral, and I think that most people disagree. Most people have a strong preference to live, rather than to die, even in a painless way. This implies that they think the value of the rest of their life is significantly higher than zero. This suggests that you are undervaluing positive experiences and overemphasizing negative experiences, compared to the values that most people place on those. And I doubt that in practice you personally think your life is worthless on balance. 2. When I say that the universe is good, I do not just mean that life or experience is overall good. If that needs additional justification, I will do that in addressing the third point. 3. I agree that a cause does not always have the properties of the effect. But goodness has a particular meaning which affects the issue. Without trying to give a formal definition, saying that something is good certainly means something like "this is a desirable state of affairs," and likewise saying that something is bad would mean something undesirable. But then if a cause brings about a good effect, it brings about a desirable state of affairs. And if the thing was desirable, bringing it about was desirable, and so there is reason to call the cause good as well, even though it s

0gjm9y

I don't think my first part says quite what you say it says, but never mind that since you've agreed not to contest it :-). On good versus neutral versus bad, and wanting to live: wanting and liking are different things, and I think there are (alas) plenty of people who feel that their life contains more bad than good but still have no wish to die. (And, also alas, some who admit that their life contains more good than bad but do want to die, at least some of the time.) No, I don't think my life is worthless on balance. I think I have an unusually good life. [EDITED to add: And I expect a lot of other people here on LW have unusually good lives too. It's a group selected for high intelligence (almost necessary to find much LW material interesting), reasonable amounts of leisure time (else we'd be doing other things), not being overwhelmed with other concerns (else again we'd be doing other things), easy access to the internet (since that's where LW is), membership in a somewhat-dominant culture (because LW is anglophone and founded by people in the US), etc. None of these things is universal here, none of them is either necessary or sufficient for a good life, but they all tend to be characteristic of LW participants and they all tend to go along with a more pleasant life.] On causes and effects: if by "good" you mean only "bringing about more desirable than undesirable effects, on balance" then I am, at least provisionally, prepared to agree that if an effect is good then that's evidence for the goodness of each of its causes. But it seems to me that this is a much weaker sense of "good" than the one usually intended by people who say that God is "good". Suppose I have a child (as in fact I do) and that I alternate between treating her kindly and beating her (as in fact I do not). If I do her more good than harm, overall, does this justify calling me "good"? Of course not. What does your argument from goodness of experience really come down to? Only this, I thin

0entirelyuseless9y

I basically agree with what you said about wanting and liking. That's one reason why it's easy for me to imagine a situation where I constantly do things that feel awful and avoid the pleasant ones. Because to some extent that already happens. But life is not even close to being like that as a whole. I also agree that people on LW are likely to have better lives on average than people in general, and also that at least some people would say that overall there is more bad than good in their lives, while still not wanting to commit suicide or anything like that. But I very much doubt that this is even close to a majority of people, even in very poor countries or in a historical sense. I realize I could be wrong about this and that (if so) someone could prove it with the proper statistics. But this is my current sense of the situation. Regarding calling the causes good, that is one reason why I said it was a distraction (relative to this argument) to talk about God. Because normally when people say "God," they think of a person, and in fact a particular person, with the result that instead of talking about some particular point, people are actually discussing whether or not the doctrines of someone's religion are true or false as a whole. In any case, as you point out, saying that someone is a "good person," has a particular meaning, certainly more than saying that overall the person causes more good than bad. But in that way there is no contradiction in someone being a good thing but a bad person, because "good thing" and "good person" mean two different things. I agree with your summary of the argument, at least as far as it goes.

0gjm9y

Well, if you detach your argumentation about good versus bad experience from talk of "God", then all you're left with is: People have more good than bad experiences on the whole, so if the universe has causes then they are more likely to be such as to generally produce (ultimately) more good than bad experiences, than to be such as to generally produce (ultimately) more bad than good experiences. Which is fair enough, but I'm sure originally this was being proposed as evidence for belief in a good god, and it really doesn't seem to me to offer more than a tiny amount (and, further, in so far as it does the highly mixed character of human experience seems to provide at least as much evidence against the perfectly good gods of various religions).

0entirelyuseless9y

Actually, that wasn't how I meant it even originally (even if in fact it is weak evidence for that). I suppose it wasn't unreasonable for you to understand it that way because I used the word "benevolence," and in reply to a comment about whether God is good or not, but in fact I was only objecting to the implied claim that the laws of physics (and therefore whatever causes them) are overall absolutely neutral, and I used the word benevolence because you used it. I agree with you that there is good evidence against the idea of God as a perfectly good person, in a literal sense, especially if you understand that in the sense that God is someone who is supposed to look at every particular thing which is happening and decide whether or not it's a good idea to allow it to happen or not. It seems very likely that no such thing is happening.

0gjm9y

Oh, OK! But in that case I wonder whether there's a miscommunication. I forget who was claiming that the laws of physics are "neutral", but what I would mean if I made such a claim is simply that nothing in those laws is about justice or charity or benevolence or honesty or anything of the kind. Of course it might turn out that the laws of physics have consequences of which we morally approve (e.g., living things tending to do things that lead to good rather than bad experiences) or disapprove (e.g., living things competing ruthlessly against one another much of the time), and if you believe in gods and devils and the like then you might think that some of those consequences are actually "design features" rather than emergent coincidences, but the laws themselves simply don't operate at the same level as moral considerations do. It seems unlikely to me that anyone here was deliberately claiming, or implying, that the laws of physics can't have any consequences to which we attach moral weight.

0entirelyuseless9y

There was probably some miscommunication, perhaps because when people talk about things they have certain interests. This can happen in a completely non-truth related way, as e.g. a website like Answers in Genesis is not interested in discovering the truth, but in arguing for creationism without any regard for reality. However, even when people want to know or discuss the truth they still have particular motivations which affect the discussion. So for example if someone is interested at the moment in thinking about one particular aspect of reality, he is more likely to interpret other people's statements as being relevant to that consideration, even if they are in fact irrelevant or less relevant than he would like. But I'm not sure it's completely an issue of miscommunication because I'm not very comfortable with your explanation here either. Let me try to summarize your comment before I try to explain why I have a problem with it: 1. The laws of physics that we know and use are mathematical laws about mass and force and so on. It is obvious that these do not contain anything about justice etc. 2. It turns out that these laws have various consequences which have moral importance for us, some good and some bad. 3. But the laws "don't operate at the same level," even if someone might suppose that the above good or bad consequences are the result of someone's good or bad intentions. If they are an argument for such good or bad intentions, they are a fairly weak argument for it. (I realize that there is more here than you said in the comment I'm replying to, but I'm summarizing also based on our previous discussion.) I agree with all three of these points. However, I still have a problem with your comment as a whole, probably because of this: "you might think that some of these consequences are actually 'design features' rather than emergent coincidences." It is perfectly obvious that mathematical laws as such are not about morality, and in that sense it is n

0hairyfigment9y

It is by no means obvious that the laws of physics could not be about morality or humans. A law to prevent human beings from losing all of their limbs would, if expressed in the same 'language' as the other laws, be absurdly long - but any being we could reasonably describe as "omnipotent and omniscient" would have no trouble creating it. I don't know if I understand the rest of the parent. Would you like to replace "oranges" with "dresses" and try again? If Martha's perceptions consisted entirely of connections, - let's say she could only register differences between the photons arriving from different areas and compare these mathematical differences with other patterns of difference, which may activate other nodes in her network - would she describe anything differently?

0entirelyuseless9y

I didn't say it is obvious that there couldn't be laws of physics about morality or about humans. I said it is obvious that the ones we actually know and use are not about those things. As for the rest, I'll adopt the style that Socrates calls "polemical," and say that "I have given my argument, if you disagree it is up to you to refute it." Mostly because I didn't want to get involved in that discussion in the first place.

0Gram_Stone9y

To be clear, I didn't think you were proposing any sort of p-zombie-like hypothesis, where mental states are epiphenomenal or otherwise. I think this is the same sort of error that a lot of people make when they ask "Why am I who I am instead of someone else?" They think that their identity exists primitively in the territory or even that it existed before their body; but it's a wrong question because they have the causality reversed. The question would make sense if you were some ghost-in-the-machine and you or someone else picked some physical body, but that's not how it works. Your body caused your mind, so you always are who you are and the question is confused. (I also don't mean to exclude the possibility of anthropic reasoning in this example.) The good and the bad don't exist primitively in the territory, they are caused by evolutionary processes that develop organisms with reward mechanisms, and we identify reward and punishment, among other things, with these high-level concepts of 'good' and 'bad' that didn't exist before us, so good is always good and bad is always bad and the question is confused. Although with what I've seen in neuroscience, some creature like what you describe doesn't necessarily seem outside of the realm of physical possibility to me. If people can simultaneously observe that they are paralyzed and come up with endless excuses for why they aren't, and the cognitive processes we're talking about in this case aren't too intertwined, then I can perhaps conceive of a creature that continues to perform adaptive behaviors but experiences suffering and happiness in the reverse. But I would expect someone to have to construct it, not for it to evolve. Or maybe an evolved creature with the most horrible sort of oddly complex neurological lesion.

-2CCC9y

That would be a reasonable argument to make. I would follow it up by claiming that the existence of free will is evidence of benevolence in the laws of physics.

2gjm9y

With what definition of "free will"?

-1CCC9y

"Free will" consists of the ability of a person to determine their own future actions by some entirely internal process (which can observe, but is not controlled by, external factors); where "person" is defined as a collection of stuff such that the collection of stuff that makes up you has no overlap with the collection of stuff that makes up me and neither of us have any overlap with the collection of stuff that makes up (say) Barack Obama, or Trevor Noah, or Jacob Zuma.

3gjm9y

Do you understand "is not controlled by" in such a way that having "free will" is inconsistent with (1) purely deterministic physics and/or (2) purely deterministic+random physics? (On the face of it your definition makes free will inconsistent with #1 but not with #2, but I can e.g. imagine a definition that restricts those "external factors" to, say, the state of the world outside one's body in at most the last year, in which case "free will" might be compatible with outright determinism.)

0CCC9y

I don't think that free will can be reconciled with purely deterministic physics - free will implies that, in exactly the same situation, with each and every particle in exactly the same space, I can still choose whether to purchase those biscuits or not. On the other hand, my decision whether or not to purchase those biscuits is not exactly random, either. There are a number of factors that go into it - in fact, considering force of habit, quite a few of my decisions are extremely predictable. So I'm not sure that random physics is entirely reconcilable either.

0gjm9y

OK. So, do you consider that you actually have good evidence for the existence of free will in this sense? If so, what is that evidence? The obvious alternative hypothesis, which seems to me to explain all the evidence I know of just as well, is that at the level of physics there's nothing but determinism and maybe randomness, but it looks different to us because we can't see all the details. We think "I could have done otherwise in the exact same situation" because we have seen ourselves and others do different things in very similar-looking situations, we can imagine making a different decision in what feels like the same situation, etc.; but we don't get to observe the exact states of all the particles that compose us and the world around us, and what we think of as "the same situation" may actually be quite different in its details. We also don't get to observe the mechanisms that lead to our making whatever choices we do, so those choices feel like opaque black-box miracles to us. No magical contra-causal free will is required for things to look this way to us.

0CCC9y

I did think I had a good argument for free will (given the existence of God), but TheAncientGeek has punctured that. (I had a second argument as well, but I'm waiting to see whether TheAncientGeek has any comment on that one). Aside from that, all I've really got is that: (a) What I do feels like free will; that may be an illusion. (b) What other people do is consistent enough to suggest that their actions are being guided by individual, similarly free-willed minds. ...both of which are fairly weak evidence, if anything.

0entirelyuseless9y

It's clear that if you put someone in very similar situations and ask them to make a choice, over time they will converge to making a certain choice a certain percentage of the time. That could easily be the same percentage of the time that would be predicted by deterministic physics plus e.g. quantum uncertainty, so I don't see any reason in principle why your account of free will could not be consistent with everything happening according to the laws of physics, if there is randomness in the laws of physics. As for the feeling, if a deterministic chess computer had feelings, it would have to have the feeling that it could make any move it wanted, because if it didn't feel that way, it couldn't consider all the possibilities, and it can't decide on a move without considering all the possibilities. This doesn't prevent chess computers from being deterministic, so it might not prevent you from having a feeling like that, even if your actions are in fact deterministic.

2Lumifer9y

No, it's not clear at all. If ask me to make choices in similar situations, first I might humor you, then I'll get bored and start fucking around with the system, and then I'll get really bored and stop cooperating with you. There won't be much of a convergence over time. The abstraction is not the territory.

2JDR9y

The problem with that model seems to be that as time goes on, the situation in which you are put in becomes increasingly dissimilar to the original one, just because of we've added memories of having had to make this choice x number of times before. If we could run the experiment so that you always felt like it was the first time you were in this situation, perhaps by putting the same kind of decision in different contexts and spreading them out over time and with various distractions, do you think you'd still deviate in the same way? I know I'm going back from territory to less practical abstraction here, but I think this kind of difficult-to-collect data would be more revealing for this question.

1Lumifer9y

Most of my point is that you can not. Among I things, I change over time. As a practical example, I drink beer. Various kinds of. My beer preferences do not converge over time. Instead, they wander over different styles, different hoppiness/maltiness/etc., even different breweries. I have no idea what kind of beer I will like in, say, a year, but it probably will be different from what I like now. Showing that something works in a toy model does not show that the same thing works in actual reality.

0JDR9y

Sure, I totally agree with you - in real life, we can really put a person in exactly the same situation twice. If we could, this whole free will argument would be a lot easier to solve. That said, I do think the toy models are useful. Pretending we can do this experiment gives an answer to the problem I've never managed to pick a hole in (and tbh getting other people's input on it is the hidden motivation for entering this discussion): If we could let you choose a beer, then rewind the universe - including all particles, forces, and known and unknown elements of cognition anyone might postulate such as souls and deities back to their starting position - then let it go again, there are only really two things that could happen: 1) you choose the same beer because that's what the universe was leading up to or 2) you choose a different beer despite the fact that all parameters of the universe known and unknown are the same. The first outcome would suggest determinism; the second randomness, or at least independence from all variables which we consider "self" such as personality, memory and perhaps souls and things, since they were all rewound with the universe. I'd be really interested to hear of any third option anyone can think of! As you say, showing this in a toy model isn't the same as showing it in actual reality; but when the actual experiment is impossible, one is arguing about abstract concepts anyway, and one has a lot of difficulty imagining outcomes not encompassed in the model I'm not sure we can do much better.

0Lumifer9y

Within the toy model, yes. In actual reality, you still don't know. The trivial third option is to drink wine :-P On a bit more serious note, if you set up the problem so that the outcomes are X and not-X, there could be no third option.

0entirelyuseless9y

I suspect that if we take the average of e.g. the bitterness of the beers that you have been drinking, it has already converged to an average, and future developments will probably not change that average much, even if there are some years when you drink sweet beers and some years when you drink bitter beers.

0Lumifer9y

Empirically speaking, you are wrong.

0entirelyuseless9y

Perhaps, although I don't see how you can know that unless you have been making measurements, or unless it has definitely been going in the direction of getting more and more sweet, or more and more bitter. In any case, since beer does not differ an infinite amount in sweetness and bitterness, it won't be easy to stop that average from converging sooner or later.

0Lumifer9y

Um, if I'm swinging from Lambics to Stouts with excursions into IPAs and Belgian Trappists, do you really think I converged on a particular bitterness? Random walk, even if bounded, does not converge.

0entirelyuseless9y

The random walk doesn't converge. But the average position does.

0Lumifer9y

The concept of convergence does not apply to the "average position". It always exists. You are probably thinking of statistical estimation with uncorrelated errors. That is not the case here, you are not estimating some unobserved parameter.

0entirelyuseless9y

I mean your average position on any day taken as the average of all the values up to that day. As days increase indefinitely, this changing average will converge (e.g. to the central value.)

2Lumifer9y

But that doesn't mean my taste in beer will converge to some value. All it means is that the average of history of my beer wanderings will be somewhere around the middle of the range -- an observation which is quite useless for the free will debate.

1entirelyuseless9y

The general point I was making is that there is nothing about free will, even if by definition it means you have more than one option in the same physical situation, which gives us a reason to expect a pattern different from determinism with the addition of some randomness. So unless someone can show how those patterns would be different, there isn't any special reason to suppose that our actions couldn't correspond entirely to the laws of physics, without that meaning we don't have free will.

1Lumifer9y

That's heavily underspecified. Most everything can be fit into a pattern of "determinism with the addition of some randomness". In any case, you started with a specific claim that the choices will converge. Outside of the toy-model setup I didn't think it was necessarily true and I still don't think so.

0entirelyuseless9y

I meant that the changing average of the choices will converge, in the way I expect to happen in the beer case. I still think this will happen under all normal circumstances.

0CCC9y

I, um... I'm not seeing what that says about free will. If you pick out a selection of numbers from one to a hundred, and you keep going, then the more numbers you pick out the less effect each new number will have on the running average. I just don't see how this leads to "free will can be explained by deterministic physics plus randomness".

0entirelyuseless9y

I don't think it proves that. I think it suggests that it may be the case. We already know that deterministic physics plus randomness will result in statistical patterns like that. I am just saying that free will is going to result in statistical patterns as well. As far as I know, those could be the same patterns, which would mean that free will would be consistent with deterministic physics plus randomness. That is not a proof. I am just saying I don't know of any specific reasons to think those patterns will be different. Do you have reasons like that?

0CCC9y

The thing is, the "pattern" you've picked up is a pattern that every series of numbers follows - that every series of numbers must follow. Any hypothesis will result in the same pattern - if I think that free will is controlled by the number of cookies eaten in Western Australia every second Tuesday, and I try to see if it follows the pattern of the average converging to a value as more samples are added, I'll find the same pattern. If "having the same pattern" is to have any sort of predictive power at all, then that pattern must be a pattern that the data can possibly not have under another hypothesis.

I'm mystified by this discussion. entirelyuseless seems to be saying that if you look at the history of choices someone has made in similar situations, they will show some kind of convergence, which I see no reason at all to believe. And CCC seems to be saying that every sequence of numbers shows this pattern, which I not only see no reason to believe but can refute. (E.g., consider the sequence consisting of one +1, two -1s, four +1s, eight -1s, etc. The average after 2^n-1 steps oscillates between about -1/3 and about +1/3.) And none of this seems to have anything much to do with free will; in so far as the "libertarian" notion of free will makes sense at all, it seems perfectly consistent with making choices that average out in the long run, at least with probability -> 1 or something of the kind, and determinism is perfectly consistent with not doing so, since e.g. the sequence of numbers I just described can be produced by a very simple computer program (at least if it either has infinite memory or has at least a few hundred bits and isn't observed for longer than the lifetime of the universe).

0CCC9y

...I had understood "converges" to mean that each successive sample moves the rolling average by a smaller and smaller amount.

0gjm9y

Well, that isn't what "converges" means in mathematics (it means there's a particular value towards which one gets and stays arbitrarily close), but with that definition it is indeed tautologously true that wandering around within a bounded region yields "converging" averaged values. (But not if the region can be unbounded. Easy counterexample: One +1, two -2, four +4, eight -8, etc.)

0Richard_Kennaway9y

If the steps get smaller sufficiently slowly, there are counterexamples similar to yours with +1s and -1s. It's difficult to get convergence short of explicitly imposing convergence. Confinement to a bounded region implies accumulation points (points to which some subsequence converges), but there can be any number of those. They can even be dense in the space.

4gjm9y

There are counterexamples to convergence-in-the-usual-sense, and my example was one of them. If one takes CCC's statement of what s/he meant by "convergence" absolutely at face value, then there are not only counterexamples but trivial counterexamples; e.g., begin 0,0,1; the first step moves the rolling average by 0 and the second doesn't. What I took CCC as actually meaning was that the differences converge-in-the-usual-sense to zero, or equivalently that one can make them small enough by waiting long enough. That's straightforwardly true because if the diameter of your region is D then after n steps your average can't move by more than D/n per step.

0CCC9y

Just to confirm - yes, that's what I'd meant. Which it trivially true, yes; that is why I couldn't understand why entirelyuseless was attaching any special significance to it.

-1Richard_Kennaway9y

That's what CCC said in his last post, but it's not a useful property for showing what was originally claimed by entirelyuseless, who said: This doesn't follow from shrinking steps, because: The sum of that over all n is divergent, so the average can move around anywhere if you wait long enough. In fact, for any number of passes of averaging, that will still be true: if the underlying sequence goes somewhere and sticks there long enough, the average will eventually get there. Then the underlying sequence can go somewhere else, and so on. To put this in more concrete terms, with an example of a property that for many people shows no long-term stability in their lifetime, consider physical location (relative to the geocentric frame). A person may live for years in one place, then years in another town or another continent, and make such moves at various times in their life. For such a person, there is no useful concept of their average location. In the case of the original example, a person's taste in beer can make just as drastic changes, on top of which, the world changes and new beers are created, the space of the random walk changes as the walk is being made. entirelyuseless's original claim: cannot be salvaged.

0gjm9y

I agree. (Did something I said give a contrary impression? I thought I'd said right at the outset that the original claims of both entirelyuseless and CCC are wrong.)

0entirelyuseless9y

I have already said that I agree that it is mathematically possible to prevent the average from converging, just that this is not likely to happen in real life. In RichardKennaway's comment, "goes somewhere and sticks there long enough" means progressively longer periods of time, and so is not realistic.

0entirelyuseless9y

I'm not saying that people's choices converge in the sense of getting closer to a particular value, but that the average converges. You are right to say that this is not a necessary property of every sequence of values (and CCC was mistaken.) You say that there is no reason to think I am right about this, but your proposed sequence of numbers suggests that I am, namely by showing that the only way the average won't converge is if you purposely choose a sequence to prevent that from happening. Suppose you offer someone chocolate or vanilla ice cream once a week. I think there are very good reasons to think that the moving average would begin to change slower and slower very quickly, and would basically converge after a while. This would happen unless the person used a sequence like the above: namely, unless he chose a sequence with the explicit intention of preventing convergence. I agree that someone can have this intention, and that this would not refute determinism. In that sense you could say that the whole discussion is irrelevant. But the relevance, from my point of view, is that it makes the question more concrete. The basic point is that you can, if you want, define free will so that it is not consistent with determinism. But then it will be consistent with determinism plus randomness, unless you propose some prediction which is not consistent with the second. And no one had done that. So no one has even suggested a definition of free will which would be inconsistent with being produced by some form of physical laws.

0CCC9y

Given that our universe clearly does operate on some form of physical laws, if anyone were to provide such a definition of free will, it should be trivial to show that it's not how our universe works.

0gjm9y

Not if the person's preferences are changing gradually over time. That is a real thing that really happens. (For the avoidance of doubt: I agree that any notion of free will it's credible to think we have is consistent with physicalism.)

0entirelyuseless9y

I agree that a person's preferences can change over time but it will not have the effect of an average that goes back and forth without his preferences changing back and forth, but remaining stable at the extremes for longer and longer periods of time (much like your sequence). This is not a likely thing to happen in real life. Anyway I also agree that the particulars of this are not that important to my point.

0entirelyuseless9y

Basically I am saying that deterministic physics plus randomness can produce any possible pattern, as you're noting. So it can also produce the pattern produced by free will. Or do you have some idea of what free will would do which is different from deterministic physics plus randomness? If so, I haven't see it suggested yet.

0CCC9y

Yes, I agree. It can. Deterministic physics alone can, if you have a long enough list of rules.

0CCC9y

...I'm not seeing this. It can consider all the possibilities even if it knows that it must play the possibility with the highest odds of winning - in fact, knowing that means that it must consider all the possibilities in order to calculate those odds, surely?

2entirelyuseless9y

Even if it knows that it must play the move with the highest odds of winning, as far as it knows when it starts considering, that could be any of the moves. But yes that would be knowledge that its move is objectively deterministic. This would not necessarily prevent it from feeling like it could make any move it wanted, just like people who believe themselves subject to deterministic physics still feel like they can do whatever they want. But the chess computer doesn't have to know what is determining its moves, in which case it will be even more likely to feel that it can make whatever move it wants.

0CCC9y

Well, yes, feeling like it has freedom doesn't really prevent it from not having freedom; but I don't see how the feeling of freedom makes any difference at all. Why shouldn't the chess computer feel constrained?

2entirelyuseless9y

I agree that the feeling doesn't make any difference. That's what I'm saying: whether it feels constrained or not, it may or may not be deterministic. Those are two different things. The same is true for us.

4gjm9y

"Free will" is an ambiguous term. The sort of free will you've argued for here could be paraphrased as "not being God's puppets", but I hope it's obvious that that can't be evidence of God's existence. But you listed "free will" as something you can explain with God better than without! I really don't think the fact that people sometimes do things a god should be expected to disapprove of can be evidence for that god's existence. Do you? (Perhaps the argument you have in mind makes essential use of the fact that humans engage in a kind of cruelty "that is absence from the laws of nature". But I don't see how that can work. We should expect human behaviour, even if entirely derived from the laws of nature, to have features that aren't apparent when looking at the laws themselves -- just as, e.g., in Conway's "Game of Life" there are phenomena like gliders that aren't apparent from the almost-trivial rules of the game.)

-2CCC9y

Ah, let me elaborate, then. Whether God exists or not, one can postulate a universe in which people are puppets - philosophical zombies, moving and acting according to some purely deterministic set of rules. In the atheistic universe, those behaviours may be at odds with one another, because the rules are not guided; they do not have an aim. They may optimise for some goal on the individual, or even the group level, but there is no reason why they should do so in an efficient manner; a puppet universe may include humans who oppose each other. In the theistic universe, the presence of an omnipotent, omniscient being suggests that there is some purpose to the universe. If all people are puppets, then, it is to be expected that all people work tirelessly towards a single goal, without opposing each other. Therefore, the observation that people oppose each other cannot be used to argue for free will in the atheistic universe, but can do so in the theistic universe. You've got it backwards. I'm not using it as evidence for God's existence; I'm using it as evidence for free will, given the existence of God as a postulate.

1TheAncientGeek9y

You are treating puppet and zombie as equivalents, but they are not. Rational deterministic agents may or may not succeed in co operating. Co-operation is probably the outcome that ideal rational agents would tend to , but non ideal agents face barriers to co operation. Puppets in a theistic universe may or may not co-operate depending on what the Puppetteer wants: some Purposes are served by struggle. Maybe the Puppetteer is a Nietzchian , who wants conflict and struggle to develop strength. Puppets may or may not oppose each other, zombies may or may not oppose each other, free agents may or may not oppose each other. There's nothing you can deduce.

0CCC9y

You are right that I am treating them as equivalent. How are they different?

1TheAncientGeek9y

Zombie=driven determinstitcally by their own inner workings, inherently predictable. Puppet=controlled by an external force, not necessarily predictable, since the Puppeteer could be controlling them whimsically.

0CCC9y

In that case, it sounds like the "zombie" is the atheistic no-free-will scenario, while the "puppet" is the theistic no-free-will scenario? In that case, my argument is that the fact that people oppose each other quite strongly at times seems to suggest that we are not puppets but neither confirms nor denies the zombie hypothesis.

2TheAncientGeek9y

Yep. I don't see that. We make our own puppets fight, eg in video games.

1CCC9y

...you make an excellent point. In fact, I think you've pretty much invalidated my entire (presented) argument for free will given the existence of God. I have an alternative argument in favour of free will (given the existence of God) if you'd like to have a look over it - it requires not just God, but a (at least vaguely) benevolent God, which is why I didn't present it earlier (it requires more assumptions therefore it is a weaker argument). In short, the alternative argument runs as follows; start with the assumption of a benevolent God (and noting the lack of malevolence in the laws of physics as at least weak evidence for the benevolence of a deity). Note that humans, unlike the laws of physics, are capable of being malevolent towards each other; extremely malevolent, in some cases. If they were puppets of a generally benevolent God, then that malevolence is out of place; and this is therefore evidence in favour of free will. (This also implies that God considers free will more important than preventing malevolence).

0gjm9y

You were earlier when the topic first came up in this thread.

-1CCC9y

Er... no, I wasn't. The question that was asked was "What can you predict with the existence of your God that you can't predict without?" I parsed this as "What can be shown, taking the existence of God as a postulate, that cannot be shown without that postulate?" And one of the things that can be shown to be at least more likely with that postulate than not, is free will. Thus, I included it in the response to the question. ...I'm now beginning to wonder if I entirely missed the point of that question.

2gjm9y

I think you did (but maybe I was the one who did); I took it to be presupposing that your belief in God is (or should be) the result of thinking that God explains some things about the world better than absence-of-God would, and asking what such things you had in mind. But maybe raydora was asking a question more like "what use is your belief?" than "what basis has your belief?". raydora, if you're reading this, which (if either) did you have in mind? Anyway: my apologies for failing to consider the possibility that you were interpreting the question so differently from me and consequently misunderstanding the point of your answers!

0CCC9y

No worries, it's all straightened out now. Incidentally, TheAncientGeek found a severe problem in my argument for free will elsewhere.

2entirelyuseless9y

Not seeing maliciousness in the laws of physics is a very weak argument for an afterlife, because even if there is no afterlife, that doesn't mean that God is malicious. It just means that he doesn't prevent things from working the way they do naturally, just like he doesn't prevent a lion from eating a man, or a man from hunting the lion.

0ChristianKl9y

Does that mean the bible which assumes that God wiped out most of humanity with the flood is definitely wrong and to the extend that God exists it's not the God of the bible?

1CCC9y

No. a) The existence of an afterlife would mean that those people were not destroyed. They had a really bad day and then woke up someplace else. b) The story of the flood, in itself, may be a parable (by which I mean, a story intended to teach a lesson, usually of a moral or ethical nature, without necessarily being true) like the parable of the Good Samaritan, or the story of the Garden of Eden. c) There may have been reason for the flood. Any one of these alternatives could answer your question; personally, I think (b) is the most likely, though (a) and (c) are also possible.

2gjm9y

What exactly do you mean by option (b)? * That whoever originally wrote that story intended it to be understood as fiction with a moral, rather than as truth? * That it may have originated as (alleged) history, but whoever incorporated it into the documents that became Jewish and Christian scriptures did so with the intention that it should be understood as fiction with a moral? * That whoever wrote it may have intended it to be seriously believed, but God arranged for it to land up in the Jewish and Christian scriptures with the intention that it should be treated as fiction with a moral? * That it doesn't really matter why it was written or how it got into the scriptures, but nowadays it should be understood as fiction? * Something else? It seems to me that the first three of these imply a certain degree of incompetence on the part of the writers, editors, or god concerned, given how widely the story has been treated as history since its incorporation into scripture. The fourth is fair enough, but it seems to me that (what I take to be) ChristianKI's inference "the bible contains this story, which is not true, so we should reduce our general confidence in what the bible says" is then reasonable (and indeed the decision to understand as fiction something in the bible that wasn't originally intended that way amounts to conceding that point). Of course if the fifth option is right then all of the above may be moot.

-1CCC9y

This is somewhat muddled by the idea that the original story may have been an oral tradition for some time before being written down - that is to say, the person who put pen to paper may not have been the one to create the story in the first place, and may in fact have been removed from that person by several generations. So it is quite possible that whoever originally created the story may have intended it as fiction with a moral, but that it may have been understood as history by the person who put stylus to papyrus. Or it may have started out as history, gained some embellishment along the way, then rephrased to highlight a perceived moral, then embellished again to further highlight that moral, then only written down. I am very uncertain of the history behind how it got there. I think that it is most probable that it is now fiction with a moral; and I think that there have been a whole lot of biblical passages that have been very firmly, and very publically, misunderstood by some people with very loud voices (such as pretty much the entire Creationism movement). I think that the Bible, especially the Old Testament, is a collection of some fiction, some non-fiction - one of the clearest examples of fiction (to my eyes) is the book of Job, which seems to be an entire story written in such a way that it can be performed as a play by a handful of actors with little-to-no equipment (all the dramatic stuff happens off-stage and is introduced by messengers running in and shouting "This happened!"). I think that the morals that the fictional parts try to show are important; they should not be simply discounted and tossed aside because they did not happen.

3gjm9y

Yeah. (I felt that my list of possibilities was already too long without bringing up the oral/written distinction, but it's important enough in view of the gradual evolution of oral traditions that that was probably a mistake on my part.) I'm not sure quite what you mean by saying that it's now fiction with a moral; just that that's how believers do (or should) read it now, or something stronger? I agree that some things in the Bible seem clearly to be intended as fiction; I'd put Jonah alongside Job in that category. And I agree that one absolutely shouldn't go from "X is fiction" to "let's ignore X". But going from "X was intended as history but turns out to be wrong history" to "let's ignore X" is more reasonable, though still not a slam-dunk (because maybe the story originated as wrong history but was kept around for the sake of things in it that don't depend on the history).

-2CCC9y

I'm pretty much saying that's how I read it. I'm not so sure about Jonah (he seems a good deal less clear-cut than Job - at the very least, Jonah would be very hard to stage without some pretty impressive special effects) but apart from that, I think I agree with everything in this paragraph.

2gjm9y

I'm not suggesting that Jonah was intended as a play; I think it more likely that it was just intended to be read (or told aloud). But it seems (1) not very likely to be true-as-history even if we assume that some fairly miracle-happy version of Christianity or Judaism is right, (2) quite well designed as a story-with-a-moral, and (3) very much like the sort of story-with-a-moral that would get written to make a point. (I'm guessing that the background is one of controversy over the attitudes Israelites should have towards nasty heathen foreigners. Jonah is not meant to be a sympathetic figure in this story.)

-2CCC9y

Well, Ninevah at least was a place that actually existed (according to Wikipedia). Beyond that... well, you make some good points, but I still think it's far less clear-cut than Job.

0ChristianKl9y

If it's a parable, isn't the parable about the fact that certain actions like gay sex are bad enough that they warrant a God engaging in genocide? Even if the God didn't actually commit the genocide but merely wanted to make the point that doing so is justified, that still seems bad to me.

0CCC9y

I think there are multiple morals. * If you do something that you know you shouldn't, there will almost certainly be bad consequences. * Not knowing what those consequences are will not prevent them from happening. * If you act in the correct way and take competent instruction, you can save yourself even while everyone around you dies. * In such circumstances, it may not actually be possible to save those around you without dooming yourself. * When going out into a dangerous situation, find some way to check how safe it is first. * Look after your animals. (This would be more relevant in a more agricultural society)

1entirelyuseless9y

CCC already said that he thinks science is mostly right about the history of the universe, so presumably he does not believe such a flood ever happened. Many Christians believe that such a flood never happened without thinking that the Bible is "definitely wrong" and without thinking that they believe in a God who is "not the God of the Bible."

1Lumifer9y

Oh ye of little faith! Global floods certainly happened in human history. What do you think happened to sea levels at the end of the last Ice Age (and humans were already around)? There are claims that memories of such a flood are preserved in legends and stories in Australia, for example. It doesn't even have to be a global flood: a big enough tsunami will suffice.

-4VoiceOfRa9y

You seem to have missed the "without reason" part.

1raydora9y

Yes, it does, though those answers lead to further questions. How can you gain information from a prediction you cannot test, until you die? Is there some way to test it? Or have you encountered personal evidence of an afterlife already? Why does free will or an afterlife require a God? It's hard to convey tone in text, but these are honest questions. If they make you uncomfortable, it's fine if you ignore them. Regarding the sequences, you may find it easier to derive the same information from books popularizing a lot of the source material it is based on, if the sequences themselves turn you off.

-1CCC9y

Well, the obvious answer is "by dying". However, this also prevents me from communicating my results, calling the usefulness of the procedure into question... No, but there are people who have. Feel free to look them up. Note that one of the requirements of canonisation as a saint by the Roman Catholic Church is that someone find evidence, sufficient to convince the Church, that the person being canonised is in the afterlife. So a look through the Vatican records will probably provide a number of examples to look over, if you'd like. They do not require a God. My argument for both requires a God, but there may be other arguments that do not. Actually, by and large they don't. There is one element of the Sequences which niggles at me a bit, but it doesn't really bother me all that much; Eleizer is perfectly entitled to his opinions.

5gjm9y

This would be more impressive if it didn't so often happen that the ones with the best-sounding evidence so often turn out to be outright fraudulent. E.g., Eben Alexander's book ("Proof of Heaven") makes claims about his illness that are demonstrably untrue, and it turns out he's been in trouble before for reasons that call his integrity seriously into question (e.g., there is reason to think he's falsified patients' medical records); Alex Malarkey ("The Boy who went to Heaven") retracted his claims to have died and visited heaven. Yeah, they do indeed require evidence sufficient to convince the church that the person is in the afterlife. Unfortunately, it doesn't seem like the church needs terribly good evidence. Typically what they want to see is a miracle performed by the proto-saint's intercession. E.g., the miracle that qualified the former Pope John Paul II for beatification (he hasn't been canonized yet) is that a nun had a neurological condition, she prayed for him to intercede for her, and she stopped having symptoms. But (1) no one actually knows exactly what condition she has or had, and hence no one knows how likely remission is even without divine intervention, and (2) she appears to have had a relapse since the alleged miracle.

2CCC9y

Yes, that is a problem - if you're making up the claim, you can make up evidence to be as convincing as you want. Considering that the Church already thinks that there is an afterlife, the burden of proof they require is almost certainly lower - possibly significantly lower - than the burden of proof that you would be looking for... it's just the potential source of evidence that came most immediately to mind at the time.

0entirelyuseless9y

John Paul II was canonized more than a year ago (you might have been looking at an older news source and not noticed the date on it.) There are definitely problems with the Church's canonization process, and if they really cared about the validity of miracles like that, they should publish the facts of the case and an explanation of why they think it was a miracle. But they don't do that, which allows for a lot more wishful thinking. A more reasonable example of a miracle claim (which is not about the afterlife) is this. Most explanations which do not accept it as a miracle are mistaken in obvious ways, as for example Brian Dunning's explanation in the linked article. I'm not sure where he got the idea that doctors did not testify to the amputation, but that is simply completely false.

1gjm9y

Whoops, you're right, he's been canonized now. Sorry about that. I agree that the most convincing miracle stories aren't about the afterlife, but the question at issue here wasn't "do miracles ever happen?" but "do we have good evidence of an afterlife?"; the question arose because CCC cited the existence of an afterlife as something better explained by his variety of theism than by atheism. (As to the specific alleged miracle you mention: at a remove of nearly 400 years, it seems difficult to say much about what actually happened; e.g., I don't see how we have enough evidence to rule out the possibility of a concerted fraud some time after the alleged events, the enquiry at Zaragoza being an outright fiction; or a smaller-scale earlier fraud along Dunning's lines, but with the doctors having been bribed to say what they did. Of course either of those would be a strange and unusual happening -- but stranger and more unusual than a completely amputated leg miraculously growing back?)

0entirelyuseless9y

I agree that even the most convincing miracle accounts do not necessarily imply that it is more reasonable to accept them than to suppose that they most likely have strange and unusual human and natural explanations. That's what I said earlier in comparing claims of revelation to claims of intelligent design in biology.

-1VoiceOfRa9y

This is circular reasoning. You can argue that your theory makes it likely that the miracle didn't happen, but then you can't use it as evidence for your theory.

6gjm9y

It's not circular reasoning; even without deciding between naturalism and the various candidate supernaturalisms we know from straightforward observation that major miracles are extremely rare and hoaxes are not so rare.

-2VoiceOfRa9y

Depending on the scale of the hoax.

-1entirelyuseless9y

I agree with you that Eliezer nowhere presents very strong arguments against religion, although he says some things that are relevant. Most likely he doesn't bother for the reasons given by gjm or similar reasons. Still, that doesn't mean that there aren't any such arguments. For example, do you think that intelligent design in biology is false? If so, consider what happens if you apply similar reasoning to the idea of revelation, i.e. that certain human claims are "truths descended from heaven".

0CCC9y

I think that the universe was created, fourteen-and-a-bit billion years ago, with a set of natural laws so designed as to end up at a desired configuration. Exactly what that configuration is, or whether the universe has reached it yet, is a question that I cannot answer. I strongly suspect, though there may be some element of bias in this suspicion, that the presence of intelligence is somehow important to that eventual desired configuration. I am very much not convinced that the shape of the body that that intelligence finds itself inhabiting is at all important. I think it is highly probable that science (in general) is more right than wrong about what happened in those fourteen-and-a-bit billion years, and that the parts that are not completely right will be made more right and less wrong by future generations of scientists. ...I'm not quite sure what you mean by "intelligent design" - I have a vague idea only - but hopefully the above will answer your question. I think that some humans may claim revelations that they did not receive, possibly out of a desire for recognition.

0entirelyuseless9y

The question would by why you would give special weight to some specific claims of revelation (in particular), if you wouldn't give special weight to the claim that the bacterial flagellum (in particular) could not have evolved. In other words, it is perfectly possible that some organs could not have evolved, and it is perfectly possible that some claims do not originate from human causes. But the problem is giving good enough reasons for accepting that in a particular case. "It looks like it couldn't have evolved," or "It looks like it didn't have human sources" are not good enough.

-2CCC9y

...what does the bacterial flagellum have to do with anything? I think I am missing some important context here. Well, the simplest argument for accepting some revelations would be that later events, unknown and unknowable at the time of the revelation, were later shown to be true (for example, predicting the time and place of a volcanic eruption or other natural disaster)

2entirelyuseless9y

Michael Behe has used the bacterial flagellum as an example of something in biology which he supposes must have been directly designed and not evolved. I don't know of any examples of detailed predictions of the future where the 1) it is clearly established that the prediction was actually made before the thing happened; 2) it is clearly established that the thing happened as stated; 3) the thing has a substantial degree of unknowable detail. Regarding the third, I mean more detail than things like, "I will die on May 3, 2020." It would be quite surprising if this turns out to be true, but not surprising enough to prove that I have some special source of knowledge, given the total number of predictions that are made by someone or other. Given that you can satisfy all three conditions, I agree that this would be a good reason to suppose that someone has some special source of knowledge. That won't make it easy for you to know which of his opinions are influenced by that source, unless you know exactly what the source is and how it affects his opinions in particular. So it still won't easily give you a reason to accept particular revelations.

-1CCC9y

...a few minutes on Google suggests that biologists have by now worked out a few plausible ways in which a bacterial flagellum might have evolved. This seems reasonable to me; I assume that the biologists are competent and know their field. ...I can think of a few biblical examples, but given the length of time between then and now (and how much even recent eyewitness accounts can be distorted) I can also see how all those examples would probably fail on point (2) at the very least. (I think I can probably find examples that pass on points (1) and (3), at least).

2entirelyuseless9y

Ok. But one of the main reasons biologists have considered the flagellum issue is because Behe proposed it as something that couldn't have evolved. So the point of that was that since there are basically an unlimited number of things in nature, many of them won't have been considered in detail by scientists, or at least we might not be able to personally find those considerations (if they are only available in some obscure academic journal, for example). So if I take some animal or some organ, check to see if anyone has found a plausible way that it could have evolved, and find out that, as far as I can determine, no one has done that, it would foolish to conclude that it must not have been produced by evolution. The point of that argument was this: The number of historical events is even larger than than the number of animals and organs in biology, so it will be even more true that many such events have had no good analysis by historians. So if I take one of these events and I don't see how it could have had historical causes, and I don't find any historians giving it a historical treatment, it would be foolish to conclude that it could not have had historical causes but must have had a supernatural cause. In both cases, in theory you could draw such a conclusion without being unreasonable, but you would need to have very strong reasons indeed. This is illustrated by the example of the difficulty of establishing that a prediction actually implies some knowledge of the future, as you conceded here. And again, even assuming that you established such a fact, it would not be easy to know what else follows from that fact.

Right. The absence of evidence of an evolutionary origin is not evidence of the absence of an evolutionary origin. Fair enough. Absence of evidence is not evidence of absence. So, in short, you're suggesting that any claim of a divine origin for any historical event actually needs to be accompanied by at least some evidence suggesting a divine origin, and not merely a lack of evidence suggesting a mundane one? That seems reasonable to me.

0entirelyuseless9y

I would agree with "at least some evidence," but I also said, "very strong reasons indeed." Basically, we already have good evidence for this: "In many cases, some event appears to have meaningful evidence of a supernatural origin, but in fact it had natural historical causes." Thus, unless you happen to be a Mormon, you probably believe that Joseph Smith's religion had basically natural historical causes, despite the testimony of his witnesses that they saw the golden plates from which the Book of Mormon was translated (which presumably he would have a hard time coming up with naturally.) So there is some evidence of a supernatural origin there, but most people don't think it had a supernatural origin anyway. The corresponding behavior in other cases would be to ask for pretty strong evidence (not just some) before you accept a claim like that.

As it happens, I am not a Mormon and I know virtually nothing about Joseph Smith. I shall simply class this whole golden plates business (about which I know nothing more than what you put in your comment) as "unknown, unclassified" until such time as I find out more. I would move it to neither the "natural historical causes" category nor the "divine causes" category until such time as I have sufficient evidence that suggests which category it should be in. ...you and I probably have different thresholds for "sufficient evidence".

"The" bacterial flagellum (actually there are different kinds and I think only one kind is relevant here) was a leading example used by proponents of "intelligent design", who claimed it was a complex system that couldn't possibly have evolved incrementally.

0CCC9y

Thanks. A brief googling suggests that biologists have figured out how it could have evolved from similar organs with different functions, which seems to neatly solve the issue.

That's called the "fallacy fallacy", BTW.

It would actually be pretty easy to transform all of the anti-religious material into e.g. anti-ufos as aliens material. Or if it would sound silly to constantly bring up the same example, alternate between similar cases.

0gjm9y

I'm not so sure. Some of the anti-religious stuff is specifically concerned with Eliezer's upbringing, and so far as I know he wasn't brought up to believe aliens are visiting earth. Some of it is concerned with the fact that religious belief is widespread among (otherwise) reasonable people, which isn't so true of UFO theories. I would guess that most of what could be replaced with material about UFOs could about equally well just be removed; it's the rest that's difficult.

-2entirelyuseless9y

You're probably right about the personal material, although I suspect you could make the theoretical points in another way. But it wouldn't be a matter of easily substituting one thing for another. One could make the points about religious beliefs relative to rationality without directly asserting that all religious beliefs are false, simply because it is obvious for simple logical reasons that the majority of such beliefs are false (because opposed religious beliefs cannot both be true), and even religious people will grant that this is the case. And the majority of such beliefs being false means that if you actually want to know the truth, you need to take a lot more care about such things than most people do, whether or not any religious beliefs are actually true. The same general point is actually true about anti-religious beliefs as well, and this may be one reason why that wouldn't be a book Eliezer could have written. For example, he said that he would rather push a button that would destroy the world if God exists, than a button that had a known probability of one in a billion of destroying the world. It seems to me more reasonable to believe that Mohammed or Joseph Smith was a prophet from God, than to push that "destroy the world if God exists" button. In other words, Eliezer's personal beliefs are unreasonable in a similar way, just in an opposite direction.

2gjm9y

I suspect (but don't know) that a lot of religious people would be almost as upset at "most religious claims are false" as "your specific religious claims are false" even though, as you say, the former is almost a triviality. I also suspect that many would fall back on claims along the following lines: "Yes, superficially my beliefs and my Muslim neighbour's beliefs contradict one another. But we are fully agreed on the existence of God, and perhaps we are just seeing the same thing from different angles." -- and then they would not be willing to agree that most people's beliefs on religious topics are wrong. I think I agree with you rather than Eliezer on the probability-of-God question, but the answer might well depend a lot on what range of possibilities we count as making "God exists" true.

0entirelyuseless9y

I don't think I've heard this particular response within my social circle, but I wouldn't be too surprised to hear it from others. And in any case I do hear things which amount to, "That may be technically true, but saying it is suggesting that my religion is likely false, and implying that is really bad." In that sense I agree that religious beliefs tend to make people have a hard time even with general abstract truths about rationality, at least as soon as they realize the implications for their beliefs.

People condition on information that isn’t true.

Of course, a good hierarchical Bayes reasoner is going to use huge amounts of prior information against small amounts of countervailing evidence. Do you start believing in ghosts every time someone puts on a white sheet and jumps out at you?

2Zubon9y

Did you mean to reply to a different post? That doesn't seem relevant to either the quote or the source article. A better metaphor here would be not believing in linens when someone puts on a white sheet and jumps out at you.

3username29y

Well, if you see something ghost-like, that's a weak evidence in favor of existence of ghosts. But it's a weak evidence, it doesn't trump everything else we know about the world.

On the other hand, in this case, it was more that they didn't check, than that they didn't believe the evidence.

I am not saying we should discard our intuitions about relative outrage, but we ought to look at them more closely rather than just riding them to a quick conclusion.

Tyler Cowen, "Just How Guilty Is Volkswagon?"

0Luke_A_Somers9y

For reference, the notions of relative outrage are between deliberate and accidental harm, and in particular that as the magnitude of the problem grows, it makes less and less difference. Also, how does a post with 0 votes end up lower on the page under the 'best' criterion than a post at -8 points????

Dupe.

investors (index funds, diversified mutual funds, whatever) who own shares in multiple companies in the same industry cause those companies to compete with each other less vigorously. These investors want to maximize the profits of the industry, not the individual firm, and fierce competition is not in their interests. So -- the theory goes -- managers increasingly manage in the interests of those investors, leading to less competition, higher prices for consumers and a host of other problems. Posner and Weyl blame institutional investors for income inequ
