Broadly speaking, I agree, and Jesus mythicist Richard Carrier would also agree:

[A]mateurs should not be voicing certitude in a matter still being debated by experts ([Jesus] historicity agnosticism is far more defensible and makes far more sense for amateurs on the sidelines) and [...] criticizing Christianity with a lead of "Jesus didn't even exist" is strategically ill conceived -- it's bad strategy on many levels, it only makes atheists look illogical, and (counter-intuitively) it can actually make Christians more certain of their faith.

But reading some of his stuff made me upgrade the idea that there was no historical Jesus from "almost certainly false" to "plausible". (Carrier has written a couple books on this -- Proving History: Bayes's Theorem and the Quest for the Historical Jesus and On the Historicity of Jesus: Why We Might Have Reason for Doubt -- but I haven't read those, only some stuff available on the web.)

  • Carrier:

    I think it is more likely that Jesus began in the Christian mind as a celestial being (like an archangel), believed or claimed to be revealing divine truths through revelations (and, by bending the ear of prophets in previous eras, through hidden messages planted in scripture). Christianity thus began the same way Islam and Mormonism did: by their principal apostles (Mohammed and Joseph Smith) claiming to have received visions from their religion's "actual" teacher and founder, in each case an angel (Gabriel dictated the Koran, Moroni provided the Book of Mormon).

    [...]

    It would be several decades later when subsequent members of this cult, after the world had not yet ended as claimed, started allegorizing the gospel of this angelic being by placing him in earth history as a divine man, as a commentary on the gospel and its relation to society and the Christian mission. The same had already been done to other celestial gods and heroes, who were being transported into earth history all over the Greco-Roman world, a process now called Euhemerization, after the author Euhemerus, who began the trend in the 4th century B.C. by converting the celestial Zeus and Uranus into ordinary human kings and placing them in past earth history, claiming they were "later" deified (in a book ironically titled Sacred Scripture). Other gods then underwent the same transformation, from Romulus (originally the celestial deity Quirinus) to Osiris (originally the heavenly lord whom pharaohs claimed to resemble, he was eventually transformed into a historical pharaoh himself).

  • Carrier:

    [I]n Jewish cosmology, all sorts of things that exist or occur on earth also do so in heaven: fighting, writing, scrolls, temples, chairs, trees, gardens.

  • (To make the following paragraph more concise I'll omit hedge phrases like "according to Carrier". And even Carrier doesn't regard this as certain, only more likely than not.)

    The writings about Jesus that come the closest to being contemporary with his putative lifetime are Paul's seven or so authentic letters. Paul, who converted to Christianity after Jesus came to him in a vision sometime around 33 CE, never claims to have met the historical Jesus, and never unambiguously talks about Jesus as a human who lived on Earth. (E.g.: Paul talks about about Jesus being crucified, but this crucifixion took place in some celestial realm not on Earth. Paul mentions "James the Lord's brother", but this means not that James was a literal brother of Jesus of Nazareth but that James is a fellow Christian, the way a modern Christian might refer to their "brothers and sisters in Christ".)

It ain’t a true crisis of faith unless things could just as easily go either way.

—Thor Shenkel

Many in this world retain beliefs whose flaws a ten-year-old could point out, if that ten-year-old were hearing the beliefs for the first time. These are not subtle errors we’re talking about. They would be child's play for an unattached mind to relinquish, if the skepticism of a ten-year-old were applied without evasion. As Premise Checker put it, "Had the idea of god not come along until the scientific age, only an exceptionally weird person would invent such an idea and pretend that it explained anything."

And yet skillful scientific specialists, even the major innovators of a field, even in this very day and age, do not apply that skepticism successfully. Nobel laureate Robert Aumann, of Aumann’s Agreement Theorem, is an Orthodox Jew: I feel reasonably confident in venturing that Aumann must, at one point or another, have questioned his faith. And yet he did not doubt successfully.  We change our minds less often than we think.

This should scare you down to the marrow of your bones. It means you can be a world-class scientist and conversant with Bayesian mathematics and still fail to reject a belief whose absurdity a fresh-eyed ten-year-old could see. It shows the invincible defensive position which a belief can create for itself, if it has long festered in your mind.

What does it take to defeat an error that has built itself a fortress?

But by the time you know it is an error, it is already defeated. The dilemma is not “How can I reject long-held false belief X?” but “How do I know if long-held belief X is false?” Self-honesty is at its most fragile when we’re not sure which path is the righteous one. And so the question becomes:

How can we create in ourselves a true crisis of faith, that could just as easily go either way?

Religion is the trial case we can all imagine.2 But if you have cut off all sympathy and now think of theists as evil mutants, then you won’t be able to imagine the real internal trials they face. You won’t be able to ask the question:

What general strategy would a religious person have to follow in order to escape their religion?

I’m sure that some, looking at this challenge, are already rattling off a list of standard atheist talking points—“They would have to admit that there wasn’t any Bayesian evidence for God’s existence,” “They would have to see the moral evasions they were carrying out to excuse God’s behavior in the Bible,” “They need to learn how to use Occam’s Razor—”

Wrong! Wrong wrong wrong! This kind of rehearsal, where you just cough up points you already thought of long before, is exactly the style of thinking that keeps people within their current religions.  If you stay with your cached thoughts, if your brain fills in the obvious answer so fast that you can't see originally, you surely will not be able to conduct a crisis of faith.

Maybe it’s just a question of not enough people reading Gödel, Escher, Bach at a sufficiently young age, but I’ve noticed that a large fraction of the population—even technical folk—have trouble following arguments that go this meta.3 On my more pessimistic days I wonder if the camel has two humps.

Even when it’s explicitly pointed out, some people seemingly cannot follow the leap from the object-level “Use Occam’s Razor! You have to see that your God is an unnecessary belief!” to the meta-level “Try to stop your mind from completing the pattern the usual way!” Because in the same way that all your rationalist friends talk about Occam’s Razor like it’s a good thing, and in the same way that Occam’s Razor leaps right up into your mind, so too, the obvious friend-approved religious response is “God’s ways are mysterious and it is presumptuous to suppose that we can understand them.” So for you to think that the general strategy to follow is “Use Occam’s Razor,” would be like a theist saying that the general strategy is to have faith.

“But—but Occam’s Razor really is better than faith! That’s not like preferring a different flavor of ice cream! Anyone can see, looking at history, that Occamian reasoning has been far more productive than faith—”

Which is all true. But beside the point. The point is that you, saying this, are rattling off a standard justification that’s already in your mind. The challenge of a crisis of faith is to handle the case where, possibly, our standard conclusions are wrong and our standard justifications are wrong. So if the standard justification for X is “Occam’s Razor!” and you want to hold a crisis of faith around X, you should be questioning if Occam’s Razor really endorses X, if your understanding of Occam’s Razor is correct, and—if you want to have sufficiently deep doubts—whether simplicity is the sort of criterion that has worked well historically in this case, or could reasonably be expected to work, et cetera. If you would advise a religionist to question their belief that “faith” is a good justification for X, then you should advise yourself to put forth an equally strong effort to question your belief that “Occam’s Razor” is a good justification for X.4

If “Occam’s Razor!” is your usual reply, your standard reply, the reply that all your friends give—then you’d better block your brain from instantly completing that pattern, if you’re trying to instigate a true crisis of faith.

Better to think of such rules as, “Imagine what a skeptic would say—and then imagine what they would say to your response—and then imagine what else they might say, that would be harder to answer.”

Or, “Try to think the thought that hurts the most.”

And above all, the rule:

Put forth the same level of desperate effort that it would take for a theist to reject their religion.

Because if you aren’t trying that hard, then—for all you know—your head could be stuffed full of nonsense as bad as religion.

Without a convulsive, wrenching effort to be rational, the kind of effort it would take to throw off a religion—then how dare you believe anything, when Robert Aumann believes in God?

Someone (I forget who) once observed that people had only until a certain age to reject their religious faith. Afterward they would have answers to all the objections, and it would be too late. That is the kind of existence you must surpass. This is a test of your strength as a rationalist, and it is very severe; but if you cannot pass it, you will be weaker than a ten-year-old.

But again, by the time you know a belief is an error, it is already defeated. So we’re not talking about a desperate, convulsive effort to undo the effects of a religious upbringing, after you’ve come to the conclusion that your religion is wrong. We’re talking about a desperate effort to figure out if you should be throwing off the chains, or keeping them. Self-honesty is at its most fragile when we don’t know which path we’re supposed to take—that’s when rationalizations are not obviously sins.

Not every doubt calls for staging an all-out Crisis of Faith. But you should consider it when:

  • A belief has long remained in your mind;
  • It is surrounded by a cloud of known arguments and refutations;
  • You have sunk costs in it (time, money, public declarations);
  • The belief has emotional consequences (note this does not make it wrong);
  • It has gotten mixed up in your personality generally.

None of these warning signs are immediate disproofs. These attributes place a belief at risk for all sorts of dangers, and make it very hard to reject when it is wrong. And they hold for Richard Dawkins’s belief in evolutionary biology, not just the Pope’s Catholicism.

Nor does this mean that we’re only talking about different flavors of ice cream. Two beliefs can inspire equally deep emotional attachments without having equal evidential support. The point is not to have shallow beliefs, but to have a map that reflects the territory.

I emphasize this, of course, so that you can admit to yourself, “My belief has these warning signs,” without having to say to yourself, “My belief is false.”

But what these warning signs do mark is a belief that will take more than an ordinary effort to doubt effectively. It will take more than an ordinary effort to doubt in such a way that if the belief is in fact false, you will in fact reject it. And where you cannot doubt in this way, you are blind, because your brain will hold the belief unconditionally.  When a retina sends the same signal regardless of the photons entering it, we call that eye blind.

When should you stage a Crisis of Faith?

Again, think of the advice you would give to a theist: If you find yourself feeling a little unstable inwardly, but trying to rationalize reasons the belief is still solid, then you should probably stage a Crisis of Faith. If the belief is as solidly supported as gravity, you needn’t bother—but think of all the theists who would desperately want to conclude that God is as solid as gravity. So try to imagine what the skeptics out there would say to your “solid as gravity” argument. Certainly, one reason you might fail at a crisis of faith is that you never really sit down and question in the first place—that you never say, “Here is something I need to put effort into doubting properly.”

If your thoughts get that complicated, you should go ahead and stage a Crisis of Faith. Don’t try to do it haphazardly; don’t try it in an ad-hoc spare moment. Don’t rush to get it done with quickly, so that you can say, “I have doubted, as I was obliged to do.” That wouldn’t work for a theist, and it won’t work for you either. Rest up the previous day, so you’re in good mental condition. Allocate some uninterrupted hours. Find somewhere quiet to sit down. Clear your mind of all standard arguments; try to see from scratch. And make a desperate effort to put forth a true doubt that would destroy a false—and only a false—deeply held belief.

Elements of the Crisis of Faith technique have been scattered over many essays:

  • Avoiding Your Belief’s Real Weak Points—One of the first temptations in a crisis of faith is to doubt the strongest points of your belief, so that you can rehearse your good answers. You need to seek out the most painful spots, not the arguments that are most reassuring to consider.
  • The Meditation on Curiosity—Roger Zelazny once distinguished between “wanting to be an author” versus “wanting to write,” and there is likewise a distinction between wanting to have investigated and wanting to investigate. It is not enough to say, “It is my duty to criticize my own beliefs”; you must be curious, and only uncertainty can create curiosity. Keeping in mind conservation of expected evidence may help you update yourself incrementally: for every single point that you consider, and each element of new argument and new evidence, you should not expect your beliefs to shift more (on average) in one direction than another. Thus you can be truly curious each time about how it will go.
  • Original Seeing—To prevent standard cached thoughts from rushing in and completing the pattern.
  • The Litany of Gendlin and the Litany of Tarski—People can stand what is true, for they are already enduring it. If a belief is true, you will be better off believing it, and if it is false, you will be better off rejecting it. You would advise a religious person to try to visualize fully and deeply the world in which there is no God, and to, without excuses, come to the full understanding that if there is no God then they will be better off believing there is no God. If one cannot come to accept this on a deep emotional level, one will not be able to have a crisis of faith. So you should put in a sincere effort to visualize the alternative to your belief, the way that the best and highest skeptic would want you to visualize it. Think of the effort a religionist would have to put forth to imagine, without corrupting it for their own comfort, an atheist’s view of the universe.
  • Tsuyoku Naritai!—The drive to become stronger.
  • The Genetic Heuristic—You should be extremely suspicious if you have many ideas suggested by a source that you now know to be untrustworthy, but by golly, it seems that all the ideas still ended up being right.
  • The Importance of Saying “Oops”—It really is less painful to swallow the entire bitter pill in one terrible gulp.
  • Singlethink—The opposite of doublethink. See the thoughts you flinch away from, that appear in the corner of your mind for just a moment before you refuse to think them. If you become aware of what you are not thinking, you can think it.
  • Affective Death Spirals and Resist the Happy Death Spiral—Affective death spirals are prime generators of false beliefs that it will take a Crisis of Faith to shake loose. But since affective death spirals can also get started around real things that are genuinely nice, you don’t have to admit that your belief is a lie, to try and resist the halo effect at every point—refuse false praise even of genuinely nice things. Policy debates should not appear one-sided.
  • Hold Off On Proposing Solutions—Don’t propose any solutions until the problem has been discussed as thoroughly as possible. Make your mind hold off on knowing what its answer will be; and try for five minutes before giving up—both generally, and especially when pursuing the devil’s point of view.

And these standard techniques, discussed in How to Actually Change Your Mind and Map and Territory, are particularly relevant:

But really, there’s rather a lot of relevant material, here and on Overcoming Bias. There are ideas I have yet to properly introduce. There is the concept of isshokenmei—the desperate, extraordinary, convulsive effort to be rational. The effort that it would take to surpass the level of Robert Aumann and all the great scientists throughout history who never broke free of their faiths.

The Crisis of Faith is only the critical point and sudden clash of the longer isshoukenmei—the lifelong uncompromising effort to be so incredibly rational that you rise above the level of stupid damn mistakes. It’s when you get a chance to use the skills that you’ve been practicing for so long, all-out against yourself.

I wish you the best of luck against your opponent. Have a wonderful crisis!

2Readers born to atheist parents have missed out on a fundamental life trial, and must make do with the poor substitute of thinking of their religious friends.

3See “Archimedes’s Chromophone” (http://lesswrong.com/lw/h5/archimedess_chronophone) and “Chromophone Motivations” (http://lesswrong.com/lw/h6/chronophone_motivations).

4Think of all the people out there who don’t understand the Minimum Description Length or Solomonoff induction formulations of Occam’s Razor, who think that Occam’s Razor outlaws many-worlds or the simulation hypothesis. They would need to question their formulations of Occam’s Razor and their notions of why simplicity is a good thing. Whatever X in contention you just justified by saying “Occam’s Razor!” is, I bet, not the same level of Occamian slam dunk as gravity.

It seems that it takes an Eliezer-level rationalist to make an explicit account of what any ten-year-old can do intuitively. For those not quite Eliezer-level or not willing to put in the effort, this is really frustrating in the context of an argument or debate.

Very true. Case in point: the belief that "minimum description length" or "Solomonoff induction" can actually predict anything.

The argument in this post is precisely analogous to the following:

Bayesian reasoning cannot actually predict anything. Choose priors that result in the posterior for MWI being greater than that for Copenhagen, and it says you should believe MWI; choose priors that result in the posterior for Copenhagen being greater than that for MWI, and it says you should believe Copenhagen.

The thing is, though, choosing one's own priors is kind of silly, and choosing one's own priors with the purpose of making the posteriors be a certain thing is definitely silly. Priors should be chosen to be simple but flexible. Likewise, choosing a language with the express purpose of being able to express a certain concept simply is silly; languages should be designed to be simple but flexible.

It seems to me that you're waving the problem away instead of solving it. For example, I don't know of any general method for devising a "non-silly" prior for any given parametric inference problem. Analogously, what if your starting language accidentally contains a shorter description of Copenhagen than MWI?

If you're just doing narrow AI, then look at your hypothesis that describes the world (e.g. "For any two people, they have some probability X of having a relationship we'll call P. For any two people with relationship P, every day, they have a probability Y of causing perception A."), then fill in every parameter (in this case, we have X and Y) with reasonable distributions (e.g. X and Y independent, each with a 1/3 chance of being 0, a 1/3 chance of being 1, and a 1/3 chance of being the uniform distribution). Yes, I said "reasonable". Subjectivity is necessary; otherwise, everyone would have the same priors. Just don't give any statement an unusually low probability (e.g. a probability practically equal to zero that a certain physical constant is greater than Graham's number), nor any statement an unusually high probability (e.g. a 50% probability that Christianity is true). I think good rules are that the language your prior corresponds to should not have any atoms that can be described reasonably easily (perhaps 10 atoms or less) using only other atoms, and that every atom should be mathematically useful. If the starting language accidentally contains a shorter description of Copenhagen than MWI? Spiffy! Assuming there is no evidence either way, Copenhagen will be more likely than MWI. Now, correct me if I'm wrong, but MWI is essentially the idea that the set of things causing wavefunction collapse is empty, while Copenhagen states that it is not empty. Supposing we end up with a 1/3 chance of MWI being true and a 2/3 chance that it's some other simple thing, is that really a bad thing? Your agent will end up designing devices that will work only if a certain subinterpretation of the Copenhagen interpretation is true and try them out. Eventually, most of the simple, easily-testable versions of the Copenhagen interpretation will be ruled out--if they are, in fact, false--and we'll be left with two things: unlikely versions of the Copenhagen interpretation, and

The minimum description length formulation doesn't allow for that at all. You are not allowed to pick whatever language you want, you have to pick the optimal code. If in the most concise code possible, state 'a' has a smaller code than state 'b', then 'a' must be more probable than 'b', since the most concise codes possible assign the smallest codes to the most probable states. So if you wanna know what state a system is in, and you have the ideal (or close to ideal) code for the states in that system, the probability of that state will be strongly inversely correlated with the length of the code for that state.
2Oscar_Cunningham
Aren't you circularly basing your code on your probabilities but then taking your priors from the code?
0Ronny Fernandez
Yep, but that's all the proof shows: the more concise your code, the stronger the inverse correlation between the probability of a state and the code length of that state.

I haven't read anything like this in my admittedly limited readings on Solomonoff induction. Disclaimer: I am only a mere mathematician in a different field, and have only read a few papers surrounding Solomonoff. The claims I've seen revolve around "assembly language" (for some value of assembly language) being sufficiently simple that any biases inherent in the language are small (some people claim constant multiple on the basis that this is what happens when you introduce a symbol 'short-circuiting' a computation). I think a more correct version of Anti-reductionist's argument should run, "we currently do not know how the choice of language affects SI; it is conceivable that small changes in the base language imply fantastically different priors." I don't know the answer to that, and I'd be very glad to know if someone has proved it. However, I think it's rather unlikely that someone has proved it, because 1) I expect it will be disproven (on the basis that model-theoretic properties tend to be fragile), and 2) given the current difficulties in explicitly calculating SI, finding an explicit, non-trivial counter-example would probably be difficult. Note that is not such a counter-example, because we do not know if "sufficiently assembly-like" languages can be chosen which exhibit such a bias. I don't think the above thought-experiment is worth pursuing, because I don't think we even know a formal (on the level of assembly-like languages) description of either CI or MWI.

Bo, the point is that what's most difficult in these cases isn't the thing that the 10-year-old can do intuitively (namely, evaluating whether a belief is credible, in the absence of strong prejudices about it) but something quite different: noticing the warning signs of those strong prejudices and then getting rid of them or getting past them. 10-year-olds aren't specially good at that. Most 10-year-olds who believe silly things turn into 11-year-olds who believe the same silly things.

Eliezer talks about allocating "some uninterrupted hours", but for me a proper Crisis of Faith takes longer than that, by orders of magnitude. If I've got some idea deeply embedded in my psyche but am now seriously doubting it (or at least considering the possibility of seriously doubting it), then either it's right after all (in which case I shouldn't change my mind in a hurry) or I've demonstrated my ability to be very badly wrong about it despite thinking about it a lot. In either case, I need to be very thorough about rethinking it, both because that way I may be less likely to get it wrong and because that way I'm less likely to spend the rest of my life worrying that I missed somethin...

If I believe something that's wrong, it's probably because I haven't thought about it, merely how nice it is that it's true, or how I should believe it… or I've just been rehearsing what I've read in books about how you should think about it. A few uninterrupted hours is probably enough to get the process of actually thinking about it started.

Some interesting, useful stuff in this post. Minus the status-cocaine of declaring that you're smarter than Robert Aumann about his performed religious beliefs and the mechanics of his internal mental state. In that area, I think Michael Vassar's model for how nerds interpret the behavior of others is your God. There's probably some 10 year olds that can see through it (look everybody, the emperor has no conception that people can believe one thing and perform another). Unless this is a performance on your part too, and there's shimshammery all the way down!

"How do I know if long-held belief X is false?"

Eliezer, I guess if you already are asking this question you are well on your way. The real problem arises when you didn't even manage to pinpoint the possibly false believe. And yes I was a religious person for many years before realizing that I was on the wrong way.

Why didn't I question my faith? Well, it was so obviously true to me. The thing is: did you ever question heliocentrism? No? Why not? When you ask the question "How do I know if Heliocentrism is false?" You are already on your way. The thing is, your brain needs a certain amount of evidence to pinpoint the question.

How did I overcome my religion? I noticed that something was wrong with my worldview like seeing a deja vu in the matrix every now and then. This on an intellectual level, not as a visible thing. But much more subtle and less obvious so you really have to be attentive no notice it, to notice that there is a problem in the pattern. Things aren't the way they should be.

My father is an atheist with Jewish parents, and my mother is a (non-practicing) Catholic. I was basically raised "rationalist", having grown up reading my father's issues of Skeptical Inquirer magazine. I find myself in the somewhat uncomfortable position of admitting that I acquired my belief in "Science and Reason" in pretty much the same way that most other people acquire their religious beliefs.

I'm pretty sure that, like everyone else, I've got some really stupid beliefs that I hold too strongly. I just don't know which ones they are!

Great post. I think that this sort of post on rationality is extremely valuable. While one can improve everyday judgment and decision making by learning about rationality from philosophy, econ and statistics, I think that these informal posts can also make a significant difference to people.

The recent posts on AI theorists and EY's biography were among my least favorite on OB. If you have a choice, please spend more time on either technical sequences (e.g. stuff on concepts/concept space, evolutionary bio, notion of bias in statistics) or stuff on rationality like this.

A good reminder. I've recently been studying anarcho-capitalism. It's easy to get excited about a new, different perspective that has some internal consistency and offers alternatives to obvious existing problems. Best to keep these warnings in mind when evaluating new systems, particularly when they have an ideological origin.

EDIT: This comment is redacted. Replace "anarcho-capitalism" with "singularitarianism" and that's the experience I'm having. It's not so much wondering if a long-held belief is false as wondering if the new belief I'm picking up is false.

"Try to think the thought that hurts the most."

This is exactly why I like to entertain religious thoughts. My background, training, and inclination are to be a thoroughgoing atheist materialist, so I find that trying to make sense of religious ideas is good mental exercise. Feel the burn!

In that vein, here is an audio recording of Robert Aumann on speaking on "The Personality of God".

Also, the more seriously religious had roughly the same idea, or maybe it's the opposite idea. The counterfactuality of religious ideas is part of their strength, apparently.

Here's a doubt for you: I'm a nerd, I like nerds, I've worked on technology, and I've loved techie projects since I was a kid. Grew up on SF, all of that.

My problem lately is that I can't take Friendly AI arguments seriously. I do think AI is possible, that we will invent it. I do think that at some point in the next hundreds of years, it will be game over for the human race. We will be replaced and/or transformed.

Have you ever heard of the term hubris? If you can't imagine ways in which the human race can be destroyed by non-nerds then that shows a lack of imagination not that it can not be done. Also, it isn't like nerds and non-nerds are actually a different species, people that do not have a natural aptitude for a subject are still capable of learning the subject,. If nerds all moved to nerdtopia other people would study what material there was on the subject and attempt to continue on. If this is not possible then you have applied the term nerd to be too broad such that it contains the majority of people and all that would be left are people that are incapable to fully taking care of themselves without some form of outside assistance and would thus destroy the human race by sheer ineptitude at basic survival skills.
1Дмитрий Зеленский
The vast majority of people is both incapable of and uninterested in creating new technology OR doing science (and their incapability supports their lack of interest). So, if nerds move to nerdtopia taking some already-deadly technologies with them, the remaining world will never create something AI-like... well, given that newborns with nerds' skills are taken away early. People are generally stupid - not only in the sense of exhibiting specific biases discussed by Eliezer but also in the sense of lack of both curiosity and larger-than-three working memory (or larger-than-120 IQ, whitherever you prefer) in the majority (and larger-than-two/larger-than-100 in a big group). Having intelligence - IQ above roughly 120 or any isomorphic measure - is something so rare that from standard p<0.05 view it's inexistent (Bell's curve, 100 as mean, 10 as sigma).
1tlhonmey
I would say that the non-nerds can't save the human race either though.  Without nerds our population never exceeds what can be supported by hunting, gathering, and maybe some primitive agriculture. Which isn't much.  We'd be constantly hovering just short of being wiped out by some global cataclysm.  And there's some evidence that we've narrowly missed just that at least once in our history.  If we want to survive long-term we need to get off this rock, and then we need to find at least one other solar system.  After that we can take a breather while we think about finding another galaxy to colonize. Yes, we might destroy ourselves with new technology.  But we're definitely dead without it.  And if you look at how many new technologies have been denounced as being harbingers for the end of the world vs how many times the world has actually ended, I'd have to think that gut feelings about what technologies are the most dangerous and how badly we'll handle them are probably wrong more often than they're right.

Trying to set up an artificial crisis in which one outcome is as likely as another is a very bad idea.

If your belief is rationally unjustfiable, a 'crisis' in which one has only a fifty-fifty chance of rejecting the belief is not an improvement in rationality. Such a crisis is nothing more than picking a multiple-choice answer at random -- and with enough arbirarily-chosen options, the chance of getting the right one becomes arbitrarily small.

A strategy that actually works is setting your specific beliefs aside and returning to a state of uncertainty, then testing one possibility against the other on down to first principles. Uncertainty != each possibility equally likely.

A fifty-fifty chance of choosing your previous belief does not constitute a reasonable test. If your belief is unreasonable, why would treating it as equally plausible as the alternative be valid?

The trick is to suspend belief and negate the biasing tendencies of belief when you re-evaluate, not to treat all potentials as equal.

Agreed. Every time I changed my mind about something, it felt like "quitting," like ceasing the struggle to come up with evidence for something I wanted to be true but wasn't. Realizing "It's so much easier to give up and follow the preponderance of the evidence." Examples: taking an economics class made it hard to believe that government interventions are mostly harmless. Learning about archaeology and textual analysis made it hard to believe in the infallibility of the Bible. Hearing cognitive science/philosophy arguments made it hard to believe in Cartesian dualism. Reading more papers made it hard to believe that looking at the spectrum of the Laplacian is a magic bullet for image processing. Extensive conversations with a friend made it hard to believe that I was helping him by advising him against pursuing his risky dreams. When something's getting hard to believe, consider giving up the belief. Just let the weight fall. Be lazy. If you're working hard to justify an idea, you're probably working too hard.

One of the problems with your examples in both economics and archeology is that less is known on the subject then what you think is known, especially if you have just taken introductory courses on the subject.

From "Twelve virtues of rationality" by Eliezer:

The third virtue is lightness. Let the winds of evidence blow you about as though you are a leaf, with no direction of your own. Beware lest you fight a rearguard retreat against the evidence, grudgingly conceding each foot of ground only when forced, feeling cheated. Surrender to the truth as quickly as you can. Do this the instant you realize what you are resisting; the instant you can see from which quarter the winds of evidence are blowing against you.

Eliezer uses almost the same words as you do.( Oh, and this document is from 2006, so he has not copied your lines.) Some posts earlier Eliezer accused you of not reading his writings and just making stuff up regarding his viewpoints.......

And you seriously believe that, in all circumstances and for all people with any false belief, those people are better off believing the truth concerning that belief? The obvious counterexample is the placebo effect, where a false belief is scientifically proven to have a benefit. The beneficial effects of false beliefs are so powerful, that you can't conduct a pharmaceutical study without accounting for them. And you are no doubt familiar with that effect. Another example would be believing that you're never better off believing a false belief, because then you have more incentive to investigate suspicious beliefs.

The difficult epistemic state to get into is justifiably believing that you're better off believing falsely about something without already, in some sense, knowing the truth about it.
0christopherj
It's actually very easy and common to believe that you're better off believing X, whether or not X is true, without knowing the truth about it. This is also well-justified in decision theory, and by your definition of rationality, if believing X will help you win. A common example is choosing to believe that your date has an "average romantic history" and choosing not to investigate. If you think you can't do this, I propose this math problem. Using a random number generator over all American citizens, I have selected Bob (but not identified him to you). If you can guess Bob's IQ (with margin of error +/- 5 points), you get a prize. Do you think it is possible for Bob's IQ to be higher or lower than you expected, and if so, do you believe you're better off not having any expectation at all rather than a potentially false expectation? See, as soon as a question is asked, you fill in the answer with [expected answer range of probabilities] rather than [no data]. It's much easier to believe something and not investigate, than to investigate and try to deceive yourself. And unless you add as an axiom "unlike all other humans for me false beliefs are never beneficial" (which sounds like a severe case of irony), then a rationalist on occasion must be in favor of said false beliefs. Just out of curiosity, why the switch from "rational" to "epistemic"?

The problem with the idea that sometimes people are better of not knowing is that it has no practical impact on how an ideal rationalist should behave, even assuming it's true.

Supposing that you are right requires us to suppose that there is both a powerful argument against reductionism, and a powerful argument in favor of psi.

Supposing that you are a crank requires only one argument, and one with a much higher prior.

In other words, if you were advocating one outrageous theory, someone might listen. The fact that you are advocating two simultaneously makes dismissing all of your claims, without reading the book you recommend, the logical response.

Eventually I began to wonder what my life experiences might look like to an atheist - religion is above all an interpretive filter that we use to make sense of our lives. Although I knew that my beliefs in God were right, what would my life look like to me if I did not belive... (read more)

It also discusses some events that are unlikely in isolation but seem trivially within the realm of chance given 100 years and approaching 7 billion people.

I became a Christian because I was a Bayesian first. I know there are others like me. I saw and experienced evidence that caused me to positively update my belief.

Now if you don't like that argument, then please tell me how can anyone become an atheist via Bayesian updating? Can your posterior really go to a point mass at zero (belief in God)? If so, please tell me what prior you were using. If not, please tell me how you define atheism.

Atheism is believing that the state of evidence on the God question is similar to the state of evidence on the werewolf question.

[-]Also_odd10 Response to previous version

Would that apply to someone with a particularly high prior on the werewolf question? So, you would agree that anyone who believes that the state of evidence on "the God question" is more positive than the state of evidence on the "werewolf question" should consider labeling themselves an agnostic? theist?

And, I presume that you believe that one's current belief in the state of evidence would be controlled by 1) verifiable general evidence, 2) experience, and 3) priors on both questions?

Then we're in agreement: you should (apparently) call yourself an atheist, and I should call myself a Christian, as we differ on #2 and #3. (not that theism = Christian, but that goes back to #2).

So here I am having been raised in the Christian faith and trying not to freak out over the past few weeks because I've finally begun to wonder whether I believe things just because I was raised with them. Our family is surrounded by genuinely wonderful people who have poured their talents into us since we were teenagers, and our social structure and business rests on the tenets of what we believe. I've been trying to work out how I can 'clear the decks' and then rebuild with whatever is worth keeping, yet it's so foundational that it will affect my marriage (to a pretty special man) and my daughters who, of course, have also been raised to walk the Christian path.

Is there anyone who's been in this position - really, really invested in a faith and then walked away?

Quite a few. Dan Barker was a Christian minister before he walked away. But the truth is, it is much harder to walk away from a religion when one is married and has a family. And sometimes, it can destroy families to even voice doubts.

Christianity isn't the only religion that has this aspect. Among Orthodox Jews there's a common refrain that too many are leaving the faith and a standard suggested solution for this is to make kids marry earlier because once they are married they are much more likely to stay in the faith.

But whenever this sort of thing comes up it is important to ask how much do the social structures really depend on the religion? Will your husband love you less if you tell you him don't believe? Will your friends no longer be friendly? Will they stop providing social support? And if they will stop being friendly on such a basis, what makes you see them as genuine friends in the first place?

There's no question that these issues are deep and difficult and should probably be handled slowly. I'd recommend maybe sending a version of your question to The Friendly Atheist- one of the writers there has a column (Ask Richard) where he regularly answers questions much like yo... (read more)

This is exactly the situation where the Litany of Gendlin seems most questionable to me. I haven't been in your situation. One option for dealing with the situation might be to learn to lie really well. It might be the compassionate thing to do, if you believe that the people you interact with would not benefit from hearing that you no longer believe. (Yes, I'm aware that I'm responding to a stale post.)
-1Kenny
I don't believe I should lie to you (or anyone) because there might be one way you might not benefit from my honest and forthright communication. So, unfortunately, I've decided to reply to you and tell you that your advice is terrible, however well-intentioned. You seem to think that if you can imagine even one possible short-term benefit from lying or not-disclosing something, then that's sufficient justification to do so. But where exactly is the boundary dividing those things that, however uncomfortable or even devastating, must be said or written and those things about which one can decieve or dupe those one loves and respects? 'Radical honesty' isn't obviously required, but I would think that honesty about fundamental beliefs would be more important than what is normally considered acceptable dishonesty or non-disclosure for social purposes.
3TimFreeman
That's not what I said. I said several things, and it's not clear which one you're responding to; you should use quote-rebuttal format so people know what you're talking about. Best guess is that you're responding to this: You sharpened my "might be" to "is" just so you could disagree. This is a rhetorical question, and it only makes sense in context if your point is that in the absence of such a boundary with an exact location that makes it clear when to lie, we should be honest. But if you can clearly identify which side of the boundary the alternative you're considering is on because it is nowhere close to the boundary, then the fact that you don't know exactly where the boundary is doesn't affect what you should do with that alternative. You're doing the slippery slope fallacy. Heretics have been burned at the stake before, so compassion isn't the only consideration when you're deciding whether to lie to your peers about your religious beliefs. My main point is that the Litany of Gendlin is sometimes a bad idea. We should be clear that you haven't cast any doubt on that, even though you're debating whether lying to one's peers is compassionate. Given that religious relatives tend to fubar cryonics arrangements, the analogy with being burned at the stake is apt. Religious books tend to say nothing about cryonics, but the actual social process of religious groups tends to be strongly against it in practice. (Edit: This all assumes that the Litany of Gendlin is about how to interact with others. If it's about internal dialogue, then of course it's not saying that one should or should not lie to others. IMO it is too ambiguous.)
[-]nshepperd110 Response to previous version

The Litany of Gendlin is specifically about what you should or should not believe, and your feelings about reality. It says nothing about telling people what you think is true — although "owning up to it" is confusingly an idiom that normally means admitting the truth to some authority figure, whereas in this case it is meant to indicate admitting the truth to yourself.

-2Kenny
And that's why I wrote "You seem to think that ..."; I was describing why I thought you would privilege the hypothesis that lying would be better. You're absolutely right that learning to lie really well and actually lying to one's family, the "genuinely wonderful people" they know, everyone in one's "social structure" and business, as well as one's husband and daughter MIGHT be the "compassionate thing to do". But why would you pick out exactly that option among all the possibilities? Actually it wasn't a rhetorical question. I was genuinely curious how you'd describe the boundary. The reason why I think it's a justified presumption to be honest to others is in fact because of a slippery slope argument. Human being's minds run on corrupted hardware and deception is dangerous (for one reason) because it's not always easy to cleanly separate one's lies from one's true beliefs. But your implication (that lying is sometimes right) is correct; there are some obvious or well-known schelling fences on that slippery slope, such as lying to the Nazis when they come to your house while you're hiding Jews. Your initial statement seemed rather cavalier and didn't seem to be the product of sympathetic consideration of the original commenter's situation. Have you considered Crocker's rules? If you care about the truth or you have something to protect then the Litany of Gendlin is a reminder of why you might adopt Crocker's rules, despite the truth possibly not being the "compassionate thing to do".
3Jiro
Rationality can't be wrong, but it can be misused. "People can stand what is true, for they are already enduring it." is technically correct, but omits factors relevant to the situations when most people consider lying to be necessary. The fact that you know something is true is itself a truth. So if you reason "they have to endure the truth whether I tell them it or not", you also have to acknowledge that by telling them you've added a second-order truth, and they now have to endure that second-order truth that they didn't before. The implication that telling someone the truth doesn't change anything because it didn't change the original truth... isn't true, Of course most people don't think in terms of "telling someone a truth adds another truth", but if you try to analyze it, it turns out that it does. Virtually nobody "cares about the truth" in the absolute sense needed to make that statement logically correct. Most people care about the truth as one of several things that they care about, which need to be balanced against each other.
0wedrifid
As a matter of logic nobody caring about the truth (in whatever sense is meant by the claim) is sufficient to ensure that the statement is always correct (the part replaced by the ellipsis need not be resolved). (The problem is that it is then probably useless.)

Because it's a possibility that the post we're talking about apparently did not consider. The Litany of Gendlin was mentioned in the original post, and I think that when interpreted as a way to interact with others, the Litany of Gendlin is obviously the wrong thing to do in some circumstances. Perhaps having these beautifully phrased things with a person's name attached is a liability. If I add a caveat that it's only about one's internal process, or it's only about communication with people that either aspire to be rational or that you have no meaningful relationship with, then it's not beautifully phrased anymore, and it's not the Litany of Gendlin anymore, and it seems hopeless for the resulting Litany of Tim to get enough mindshare to matter. I'm not curious about that, and in the absence of financial incentives I'm not willing to try to answer that question. There is no simple description of how to deal with the world that's something a reasonable person will actually want to do.

There are several things to ask about beliefs like this:

  1. Do they make internal sense? (e.g. "What is the fourth dimension?")

  2. Do they match the sort of evidence that you would expect to have in the case of non-delusion? (e.g. "Do you have any observable physical traits indicating your extraterrestrial origin? Would someone looking into records of your birth find discrepancies in your records indicating forgery?")

  3. Do they try to defend themselves against testing? (e.g. "Do you expect to illuminate a completely dark room at night by generating light? Would you expect to exist happily in psychological conditions that would harm normal humans by subsisting on aid packages full of love?")

  4. Do they have explanatory power? (e.g. "Has there, as a matter of historical fact, been a sudden and dramatic reduction in global strife and suffering since the date of your supposed arrival?")

  5. Do they have a causal history that can be reasonably expected to track with truth across the entire reference class from an outside view? (e.g. "Did you receive your information via private mental revelation or a belief from as long ago as you can remember, similar to the beliefs of people you do consider crazy?")

Hi, Alicorn! 1. Yes. They are drawn from the material at http://lawofone.info/ . The philosophy presented there is internally consistent, to the best of my understanding. 2. There is no physical evidence. All of the "evidence" is in my head. This is a significant point. 3. There are a variety of points in the source document which could be interpreted as designed to defend its claims against testing. This is a significant point. 4. I am not aware of any physically testable predictions that these beliefs make. This is a significant point. 5. The causal history of these beliefs is that I read the aforementioned document, and eventually decided that it was true, mainly on the basis of the fact that it made sense to my intuition and resonated personally with me. This is a significant point. Thanks for asking!

Currently reading Law of One. I'm not sure what the mechanism is, but it seems to involve people receiving telepathic messages (from an entity named Ra) and speaking them aloud. I would like to note that I have experienced messages coming into my head, seemingly from outside (either as voices or as an impulse to write), and can even occasionally cause it voluntarily. Their content can be partially unexpected, but it never contains information I could test independently. I consider this an entertaining misbug in my brain, not evidence of an external telepathic entity.

I'm not going to say which direction I lean, but I lean that direction very strongly. My friends lean that way. My parents do not lean that way as much as I do but they are in that general direction.

And I realize that I may not lean that way because it is the rational way to approach a well-run country, but because I am merely used to it.

I started letting go of my faith when I realized that there really isn't much Bayesian evidence for it. Realizing that the majority of the evidence needed to believe something is used just to isolate that something out of all the other possible beliefs finished it off. But I do have one question: If Jesus wasn't magic, where did the Bible even come from? Lee Strobel "proves" that Jesus died and came back from the dead, but his proofs are based on the Bible. Why was the Bible so widely accepted if there wasn't anything extra-special about Jesus after all?

Asking similar questions about the Quran and various other religion's holy texts, and just general popularity of many cults and things, makes you realise an idea or set of such things has no requirement to be true to be popular. In fact, looking at the self-help section in a bookstore reminds you of this (see Lukeprog's self-help sequence first post). I also believe that Richard Carrier has a book called 'Not the Impossible Faith' which discusses this question, although defo check that if you're thinking of buying for that purpose.

Well, if you make the assumption that Jesus existed and behaved as described in the New Testament, this reduces to Lewis's trilemma. The criticisms section of that page outlines some of the possible responses. The option I personally find most compelling is that there's plenty of room for distortion and myth-making between Jesus's ministry and the writing of the earliest Christian works we know about: at least four decades [ETA: got this wrong earlier; see downthread], possibly more depending on how generous you're being. Knowing what we do about how myths form, that's more than enough time for the supernaturalism in the Gospels to have accumulated. Look at it this way and it's no longer a question of "lunatic, liar, or Lord"; rather a colossal game of Telephone played between members of a fragmented and frequently persecuted sect, many of whom would have had incentive to play up the significance of the founding events. There are more recent religious innovations that you can look at for comparison: Mormonism, for example, or Rastafarianism. Some have even used this to argue against the historicity of Jesus, although I don't think doing so is necessary to a secular interpretation of the New Testament.
1Protagoras
How do you get "between a hundred and twenty and two hundred" years? The standard story puts the death of Jesus around 30 B.C.E., and dates the composition of the earliest gospel to around 70 B.C.E. Admittedly, the standard story is certainly not beyond question[1] but I'd be interested if you had any specific reasons for advocating a different timeline. Of course, 40 years is more than sufficient for pretty much unlimited distortion and mythmaking anyway. [1] The chain of reasoning for dating the composition is, sadly, too often along these lines: we know that A was certainly written before date X, because A must be before B. We know this because B contains a vague reference that kind of looks like it refers to A, and it doesn't look all that likely that B was tampered with by later scholars to insert the reference. B must be before C for similar reasons, and C before D, and D before E, and E actually contains some fairly specific references to being written around date Y which we again don't think are all that likely to have been tampered with by later copyists. It is unlikely at each stage that the next writer acquired and made use of the text as soon as it was written, so we subtract a few years from Y for each stage for the transmission of the text and arrive at X as the latest possible date for A to have been written.
1Nornagest
My mistake, I was thinking of non-Christian references to the life of Jesus (and didn't have the dates quite right there either; Tacitus wrote in the early second century and Josephus late in the first, although both references are rather brief). As best I can tell, you're right about the chronology of Christian writings; Mark is thought to be the earliest of the surviving Gospels, and that was probably written around CE 70. The hypothetical Q source may have come somewhat earlier, but seems to have been a collection of sermons and proverbs rather than a gospel as such, if its projected influence on later works is anything to go by. Edited to correct. But yes, forty years is a large enough gap to explain a lot of drift.
1Protagoras
Ugh. Why'd I write "B.C.E." when I meant "C.E."? Oh well, I guess it didn't confuse anyone. Anyway, besides a handful of people who question the usual gospel dating and try to argue that it was really considerably later, I know there's also a tiny minority of scholars who date the life of Jesus much earlier, as much as a century or more before what the standard story reports. Hence, I'd wondered if you were a subscriber to one of those theories. It means having to assume some of the references to contemporary events in the gospels are just wrong, but honestly the standard story also has to do that; it just has a different set of mistakes it needs to explain away. Still, it's a pretty tiny minority theory, and I haven't really investigated what the evidence for it is supposed to be.
6Salemicus
Some people wrote it down. That's also the Christian story of where the Bible came from. There probably was something extra-special about Jesus, in the sense that he was highly charismatic, or persuasive, and so on. And his followers probably really did think that he'd come back from the dead, or at least that his body had mysteriously vanished. But none of that adds up to magic or divinity. Look at people in the current day - convinced (rightly or wrongly) in the existence of aliens, or homeopathy, or whatever else. "If L. Ron Hubbard wasn't magic, where did Dianetics come from?" Alternatively, consider Joseph Smith. He's far more recent and far better-attested than Jesus, who also had a loyal group of followers who swore blind that they'd seen miracles - even the ones who later broke with him, and who after his death, carried on his teachings and founded a religion with the utmost seriousness and in the face of extreme hardship and sacrifice. Yet chances are you're not a Mormon (or, if you are a Mormon, consider Mohammed ibn Abdullah). Apply the same thinking to Jesus's life as you do to that of Josepth Smith, and see where it takes you.

Broadly speaking, I agree, and Jesus mythicist Richard Carrier would also agree: But reading some of his stuff made me upgrade the idea that there was no historical Jesus from "almost certainly false" to "plausible". (Carrier has written a couple books on this -- Proving History: Bayes's Theorem and the Quest for the Historical Jesus and On the Historicity of Jesus: Why We Might Have Reason for Doubt -- but I haven't read those, only some stuff available on the web.) * Carrier: * Carrier: * (To make the following paragraph more concise I'll omit hedge phrases like "according to Carrier". And even Carrier doesn't regard this as certain, only more likely than not.) The writings about Jesus that come the closest to being contemporary with his putative lifetime are Paul's seven or so authentic letters. Paul, who converted to Christianity after Jesus came to him in a vision sometime around 33 CE, never claims to have met the historical Jesus, and never unambiguously talks about Jesus as a human who lived on Earth. (E.g.: Paul talks about about Jesus being crucified, but this crucifixion took place in some celestial realm not on Earth. Paul mentions "James the Lord's brother", but this means not that James was a literal brother of Jesus of Nazareth but that James is a fellow Christian, the way a modern Christian might refer to their "brothers and sisters in Christ".)

The predominant ways in which Christianity has spread are conversion by the sword, parent to child transmission, and social ostracism for people who refuse to believe it. It spreads for reasons related to its fitness as a system of ideas but unrelated to its factual truth. This is not how evolution spreads. Also, distinguish between "anyone can claim X" and "anyone can correctly claim X". Creationists could claim that evolution spreads the same way--but they'd be wrong.

Maybe there's a confusion being caused here by the sentence "This is not how evolution spreads."

It's not a counterargument, it's an observation about the limits of the maxim quoted. And while it can certainly be misapplied, are you going to argue that a memetic plague never happens?
2CCC
Then I may have misunderstood the intention of the phrase. As an observation about the limits of the maxim, I agree with it. And no, I'm not going to argue that a memetic plague never happens. I am, however, going to argue that a memetic plague is hard to identify, making this observation very difficult to actually apply with any reliability. It's just too easy - if I see a bunch of experts in the subject all saying something that I disagree with - for me to think "they're infected by a memetic plague". It's so much more comforting to think that than to think "maybe I'm wrong" - especially when I already have some evidence that seems to say that I am right. So, while this observation can be applied correctly, it would be far, far too easy to misapply. And if I were to misapply it - I would have no idea that I am, in fact, misapplying it. As a general observation, then, I cautiously agree. As a specific argument in virtually any debate, I deeply mistrust it. I hope that makes my position clearer.

We know how religion spreads. We know it well enough that when it is obvious enough that the "experts" are basing their "expertise" on religion, we can ignore it without worrying that we are just dismissing the experts because doing so is comforting. It's not as if the way religion spreads is seriously in question.
2CCC
I'm not sure that you do. From your previous post: If this were true - and if it were an exhaustive list of the predominant ways - then I would expect to see the following: * Parent-to-child transmission only works if the parents are Christian. Social ostracisation only works if a majority of a given person's possible social acquaintances are. * Thus, the only means on the list of introducing is into a new area is by the sword * Thus, I would expect missionaries to either have been abandoned, or to be given a sword as standard equipment on setting out. I do not see this. * Furthermore, I would expect to see, in countries where it is not a majority religion, it would slowly fade and die (as social ostracism is used against it by the majority) Now, I am not saying that it is never spread by such means. (Fortunately, 'by the sword' appears to have been largely abandoned in recent history). But assuming it to be an exhaustive list does not appear to match reality - there seems to be a rather large gap where a single missionary, armed with nothing more than information and presumably a fairly persuasive tongue, can go into a large enough group of humans who have little or no previous knowledge of religion and end up persuading a number of them to join.
0entirelyuseless
This is a good argument, and one way of seeing that is by contrast with Islam, where the method described is historically much closer to being exhaustive -- and in general it was indeed introduced into new areas was by means of swords, and missionaries did take swords with them as standard equipment. (In the future Islam may continue to spread more in the fashion that Christianity did in the past, however.)
0onlytheseekerfinds
This idea seems to be more or less taken for granted by people who oppose either Islam. Is there actually a perspicuous source of data describing in detail how Islam spread, that allows assessments of that kind to be made?
0entirelyuseless
You could start by reading about the topic on Wikipedia (that will also refer you to many other sources.) Of course you could say that probably most of those articles and their sources were written by non-Muslims. But that is like saying that most people who have argued for any position have tended to be people who believe that position, and therefore we should ignore their arguments.
0onlytheseekerfinds
reading about the topic on Wikipedia Just because there's an article on the spread of Islam doesn't mean that a balanced quantitative analysis on the means of its proliferation either exists or is possible. Usually when someone asserts something to that effect, the onus is on them to support their assertion by referencing a specific source.
0Jiro
No, it just has to get big enough that Christians have enough other Christians around that the social structure becomes self-sustaining. Social ostracism is used to get rid of spontaneously appearing non-Christian individuals, not large groups. So don't assume it's an exhaustive list. It really doesn't matter for the purposes of my point that it also spreads through peaceful missionaries. You seem to think that I'm complaining that Christianity spreads violently, so you're bringing up non-violent missionaries. But that isn't my point. My point is that Christianity spreads as a meme system. Belief systems have traits which lead them to spread regardless of their truth. Some of those traits I listed above. Other traits include, of course, the belief system telling its members to send out missionaries to spread the belief system. Having missionaries is an adaptation which helps the belief system to spread, in the same way that coconuts being able to float so they can travel to distant islands helps coconuts to spread. Belief systems which spread efficiently will do better than belief systems that don't, and will soon cover as much area as they can right until they run into other well-adapted belief systems.
1CCC
Fair enough. A neighbourhood or other small community can be self-sustaining, then. But it still needs to be started. As soon as I don't assume it's an exhaustive list, your point collapses. Yes, it does spread as a meme system, This is because it is a meme system. Newtonian physics is also a meme system. And Newtonian physics can also spread as a meme system, in all three of the ways you describe. (I don't think anyone ever has tried to spread Newtonian physics by the sword, but it could be done in theory; but Newtonian physics has most certainly been spread by parent-to-child transmission and by social ostracisation). Similarly for relativistic physics. Or, for that matter, any other descriptive model of the universe, including ones that are perfectly accurate and 100% true. Because any descriptive model of the universe is a meme system, and can therefore be spread as a meme system. Your conclusion, in short, relies on the idea that Christianity is only spread by means that are not dependant on the truth of its ideas, and never spread by means that are dependant on the truth of those ideas. This you have not shown.
0Jiro
It isn't all or nothing. These methods of transmission exist for Newtonian physics, but they are much less fundamental to how Newtonian physics spreads. If it's medieval times, and I announce to the members of my village that I'm not a Christian and act accordingly. I may end up dead, lynched, expelled, tortured by the Inquisition, or sent to a ghetto. If i get up now and announce that I don't believe in Newtonian physics, not much is going to happen to me unless I have a job that depends on Newtonian physics. The social ostracization may not be completely missing (people can still laugh at me), but it's far weaker than for Christianity. And parents teach Christianity to their children because Christianity directly asserts that it is good to teach itself to your children, and implies that their children will be in terrible supernatural peril if they don't. There really isn't anything comparable for Newtonian physics that isn't related to the fact that Newtonian physics works--if parents don't teach their children not to walk off cliffs, the children won't grow up to refuse to teach Newtonian physics to their own children.
4CCC
I'm pretty sure that the main modern transmission vector for Newtonian physics is schoolteacher-to-child (which is very similar to parent-to-child, except that the parent hires an intermediary). Mind you, I don't have any stats or data handy to back that up, it's just a general impression.
0Jiro
But again, that happens because it's piggybacking on the fact that people teach things that work. Since science works, it gets taught. If science didn't make factual claims with real-world implications, nobody would teach it. Religion is not bound by this; it gets taught even in the absence of such factual claims, because it has a bunch of commands that amount to "spread this religion regardless of the facts".

I think there's some equivocation here between different meanings of "expert". Experts in Shakespeare are experts in what Shakespeare said and what things mean within the context of Shakespeare's plays and Shakespeare's life. A comparable "expert in Christianity" would be able to tell me what Christianity claims and put it into context as a whole. But "amateurs should defer to experts", in reference to Christianity, doesn't mean "amateurs should accept the experts' word about Christianity," it means "amateurs should accept the claims presented by Christianity". There's nothing comparable for Shakespeare. In this sense, neither experts nor schools teach Shakespeare at all.
2CCC
Um. Going back to the comment that started this all - over here - shows that the quote originally comes from this page, which is an essay written from the atheist perspective on how to go about arguing the historicity of Jesus. The 'experts' in question appear (to me) to be not theologists but historians, seeking whether or not a given person, referenced in certain historical documents, actually lived at one point or not, and the author bluntly states that he expects the odds of said existence, using his best estimate of requisite probabilities, to be about one in twelve thousand. (He then goes on to say that this is far from the least likely claim in the Christian faith; supernatural miracles are far more unlikely, and thus far better things to call into question). So, no, the original context does not say that amateurs should accept the claims made by Christianity (and it does not define professionals by their religious leanings). It says that amateurs should not take a firm position on a question where the experts do not take that firm position. (It does not say that the amateurs have to agree with the experts when those experts do take a firm position, amateurs are allowed to remain uncertain).
0ChristianKl
You made a claim that schools teach their curriculum because the curriculum is useful. (e.g. If science didn't make factual claims with real-world implications, nobody would teach it) Teaching Shakespeare is an example where it's not clear whether there any use to it. Schools might simply teach it because teaching Shakespeare is high status. The math curriculum is also not optimized by teaching children the kind of math that's likely to be useful for them. It instead tries to teach them calculus because calculus is high status while making Fermi estimates isn't.

I didn't claim that the only reason schools teach their curriculum is that it is useful. There can be (and are) different parts of the curriculum taught for different reasons, some related to being useful and some not.

How do you know that the reason students teach Newtons laws is them being useful and not for status purposes?
0hairyfigment
How well do they serve each purpose? I'm given to understand Newton's Laws are highly useful in engineering. How do they compare with alternative means of producing status, like teaching everyone 'Ubik' and 'fnord?'
0ChristianKl
But most students will not do jobs as engineers. Touch typing is a useful skill for nearly all jobs yet most schools don't teach it. There are no professors of touch typing that give the subject academic prestige. On the other hand academic physic has prestige. Calculus has more academic prestige than statistics and thus schools are focusing more on teaching calculus.

The book "The Rise of Christianity" is an excellent analysis, using the tools of modern sociology, of the rise of Christianity in the Roman Empire. Key insights 1. It grew exponentially mostly via transmission from people you knew. As your social world became more than 50% Christian, you were more likely to convert. In recent times Mormanism has grown in a similar fashion. 2. It had many rules that encouraged having large families (no birth control, no abortion, no infanticide, no sex outside marriage which encouraged young marriage, bans on many sources of fun other than having sex with your spouse, bans of divorce which made marriage more secure in a sense). 3. The higher status of women in Christianity than in the Roman world encouraged women to convert. An example of this higher status was that a pagan man could order his wife to have an abortion. Many of the patriarchal statements in the new testament were latter additions when the church, which was originally very egalitarian, did become very patriarchal. 4. Christians were only allowed to marry pagans if the pagan converted, or at a minimum, agreed for the children to brought up as Christians. 5. (3) and (4) combined with the shortage of women due to infanticide of female children meant that men who wanted a wife often had little choice but to marry a Christian. The children would then be Christians. Once they achieved critical mass they seized control of the state and enacted coercive measures which ruthlessly crushed the other religions. As an example, even visiting pagan temples was banned, books were destroyed, priests killed, temples burned or converted to churches.
3onlytheseekerfinds
Another factor is that Christianity is exclusive - one could not adhere to Christianity and, say, Mithraism at the same time, since Christianity claimed a monopoly on religious truth. Other saviour cults which did not function in the same way would not have been able to work up the same amount of religious fervour, since a man's trust in his religion is limited by that religion's trust in itself.

When do you believe this happened, aside from cases where "Jesus" was translated as "Buddha"? Missionaries today typically harass other Christians.
1CCC
A brief Google points me at this fellow. He was a medieval Fransiscan missionary to China, and established what appears to have been a reasonably successful church there that stayed around for about forty years after his death (until the Ming Dynasty arose in 1369 and expelled them from the country).
2gjm
You would expect (peaceful) missionaries to be abandoned (at least as a tool for spreading Christianity to places where there is no Christianity) if there were a careful effort to track their effectiveness. I do not believe there usually is. Is your impression different? If you look at the places where there are a lot of Christians, they do seem to match up pretty well with (1) where the Roman Empire was plus (2) places colonized by countries that used to be part of the Roman Empire. One obvious counterexample is Korea, which (I think) is evidence that missionaries can sometimes introduce Christianity to a new place with long-term success. But what others are there? (Incidentally, I think your analysis is incomplete. Another way to introduce Christianity to a new area would be immigration. I don't know to what extent this has actually happened.)
0CCC
I don't think you need a careful effort to track their exact effectiveness. It would be fairly obvious in a couple of generations that peaceful missionaries would fall in one of two categories - either they have some success (as evidenced by some number of converts that they win over) or they have no success (as evidenced by every missionary outreach pretty much collapsing as soon as the missionary either leaves or dies). A careful effort to track effectiveness could tell the difference between slight success and strong success, but I think that even with a merely cursory checkup people could tell the difference between some success and no success at all. I'm not surprised. There are many possible explanations for this; a sufficient explanation might be that these are places that early (Latin-speaking) missionaries could be reasonably sure of finding Latin-speaking people, and thus were not required to face the additional hurdle of learning a new language first. Hmmm... would Japan count? That is true. I don't know to what extent that has happened either, but I imagine it would be accompanied (if successful) by a very strong spread of the immigrant's culture in other ways, as well. (Such as language).
0gjm
I think missionaries are usually sent to particular places by organizations, and when one leaves another goes. So there isn't opportunity to identify where they aren't making progress. And the actual question isn't really "no success" versus "any success"; no one claimed or implied that converting people is literally impossible, only that generally when Christianity spreads successfully it does so along with military conquest. You're welcome to be (having had the facts pointed out to you) as surprised or unsurprised as you please; I remark that much the simplest explanation would seem to be that Christianity mostly spreads by military conquest. It's hard to tell how big a Christian community the missionaries there were able to produce. (Right now, as I understand it, Japan is one of the world's least religious countries, so I guess you are thinking of the 17th century.) So, I dunno: maybe? ... Oh, I thought of another way for Christianity to get into a new area that's consistent with the "converting people is really ineffective" narrative. Again, no one claims that converting people is 100% ineffective. So, what you do is to find a place whose rulers are very much in control of the population, and send your missionaries to the royal court or whatever. They probably won't convince the ruler, but if they do then bingo, you've got thousands or millions of new converts fairly immediately. I think this has happened once or twice. I bet it's been attempted a lot more.
0CCC
It's not going to be perfect. Sometimes there will be more missionaries than established places to send them, and new missions can be opened - but sometimes a missionary will, through mischance or malice, die before he's expected to do so and there will be no replacement ready to send. I don't actually know about specific incidences, but there should be enough data on what happens when a mission is abandoned to be able to tell how successful it can be. That is a simple explanation, yes. Another simple explanation is that Christianity mostly spreads where language barriers don't get in the way. I don't see either of these two explanations as being significantly simpler than the other. Hmmmm. That would be a sensible scenario. There have also been cases where non-Christian rulers, perhaps fearing the political power of the church, made practice of the religion illegal, with severe punishments for doing so. Taking the two together, it seems fairly clear that converting the ruler would be a very important step for many successful missionaries.
2gjm
I remain doubtful, but perhaps you're right. Also a reasonable hypothesis. Hmm, do we have cases where the boundaries of the Roman Empire don't match up well with linguistic boundaries? Probably not, simply because anywhere conquered by the Romans would probably have tended to learn to speak Latin, producing an artificial lowering of language barriers within the empire. Yes. Though in the most famous recent case I can think of -- the Soviet Union -- it seems that they weren't very effective in suppressing Christianity; it came back pretty strongly once the communists lost power. Still, paying a lot of attention to the ruler(s) does seem like an effective strategy for those wanting to spread a religion to a new place. Going back to the higher-level question of how necessary conquest is to the spread of Christianity: there are apparently something like 100M Christians in China, and not because China was ever conquered by Christians. On the other hand, in the past there seem to have been multiple instances where Christian missions produced a fair number of converts but then the religion largely died out until the next wave of missionaries came in. My impression after all this is as follows. (1) It is certainly not impossible for Christianity to spread without conquest, and there are a few major instances where it has done so. (2) Most of the world's Christians, however, are part of Christian communities that got way way by conquest. (3) Attempts to spread Christianity by mere persuasion are sometimes very effective but often very ineffective. I would expect that all these things apply equally to any other major religion. #2 will of course be untrue for religions that have never gained official approval by any political power, but we should expect all such religions to be pretty small in numbers for that exact reason. Maybe Hinduism is a sort of exception, being found almost exclusively in India, but I am shockingly ignorant of Indian history and don't know whether
0CCC
Hmmm. I don't know enough history to be able to name specific situations, but what about the other way round - countries that learned Latin without being conquered? (Perhaps for ease of trading?) I believe the Roman Empire once tried to suppress it as well. It doesn't appear to have worked then, either. Yes; there seem to have been specific instances where missionary conversion worked, and specific instances where it did not. Those conclusions do not seem unreasonable to me. I think it also depends somewhat on the structure of the religion in question. Judaism doesn't have missionaries, for example, and I don't think there's any way for a non-Jew to become a Jew (I may be wrong on that point, but if there is, the Jews certainly don't advertise it).
0entirelyuseless
You can convert to Judaism. However you are right that they are not actively interested in converting someone. There seems to be a certain historical arc here. The earliest religions did not try to convert anyone because they were simply part of the culture of an individual nation, and you don't convert people to a nationality. Judaism is part of this tradition but at the border of the next, namely the point where people realize that insofar as religions make claims about the world, it does not make sense for some people to accept them and some people to reject them. If a claim about the world is true, everyone should accept it. This leads religions to try to convert people. Now we are reaching a third stage: as even religious people come closer to realizing that those claims were not actually true in the first place, even the religious people are backing away again from converting people. An example would be Pope Francis condemning proselytism and saying that he is not interested in converting Evangelicals etc.
0Houshalter
Consider also that religions that convert more people tend to spread faster and farther than religions that don't. So over time religions should become more virulent.

If all experts are infected with meme plagues, and are able to prevent alternative views from being presented, then you have a problem. This implies that one of the following is true: * Studying the subject at all carries a strong risk of meme plague infection * Only those pre-infected with the meme plague have the interest and/or the ability to study the subject * You're wrong about something - either the presence of the meme plague or its spread or... something. You could attempt to study the subject to expert level yourself, taking appropriate anti-meme-plague precautions; but you have to be very careful that you're not shutting your ears to something that's really true (you don't want to become a climate-change-denying weather expert, after all) so you'll need to seriously consider all necessary data (maybe re-run some vital experiments). This would take significant time and effort. I don't know what other strategy could reasonably be followed...
4Lumifer
Real-life example. A relevant quote:
2CCC
Huh. Okay. In this particular real-life example, though, it is clear that the politicisation is in the infrastructure around the science, not in the science itself. That is to say, learning climate science is not memetically dangerous - it is simply difficult to get a paper published that does not agree with certain politics. And that is bad, but it is not the worst possibility - it means that someone merely studying climate science is safe in so doing. So, in this particular case, the solution of studying climate science oneself, becoming an expert, and then forming a suitable opinion is a viable strategy (albeit one that takes some significant time). (An alternative solution - which will also be a hard thing to do - is to create some form of parallel infrastructure for climate science; another magazine in which to publish, another source of funding, and so on. There will likely be serious attempts to politicise this infrastructure as well, of course, and fending off such attempts will doubtless take some effort).
0Lumifer
If you are an autodidact and study the climate science by yourself from first principles, yes, it's not dangerous. However if you study it in the usual way -- by going to a university, learning from professors and published papers, etc. -- you will absorb the memes.

Hmmmm. Depends how ingrained the memes are in the material. Oh, you'd certainly have awareness of the memes - but accepting them is a different story, and a certain skepticism in a student (or in a professor) can probably blunt that effect quite a bit. Even if the memes are that thoroughly integrated, though, the only effect is to make the establishment of a parallel infrastructure that much more appropriate a solution.
0waveman
There is another possibility: the selection process for experts eliminates diverse perspectives. Try getting tenure as a political scientist as a conservative republican, as an example. But there are more subtle problems. For example, the selection process for medical doctors actively screens out people with a high level of mathematical and statistical skill, knowledge and ability. It does this by very strongly selecting for other characteristics - ability to memorize vast arrays of words and facts, physical and mental stamina. Because if you strongly select for X, it will generally be at a cost to anything else that is not strongly correlated with X.
2hairyfigment
Your second point is clearly true. The first seems false; Christianity makes much more sense from a Greco-Roman perspective if Jesus was supposed to be a celestial being, not an eternal unchanging principle that was executed for treason. And the sibling comment leaves out the part about first-century Israelites wanting a way to replace the 'corrupt,' Roman-controlled, Temple cult of sacrifice with something like a sacrifice that Rome could never control. Josephus saw the destruction of that Temple coming. For others to believe it would happen if they 'restored the purity of the religion' only requires the existence of some sensible zealots.

Would you say the origins of other religions become more mysterious if there never were whatever magical beings those religions posit? Would you think it likely that Guanyin was real human of unknown gender? Do the origins of fictional stories become more mysterious if there never were the fictitious characters in the flesh? Did Paul Bunyan exist, as there were similar lumberjacks? You're not supposed to tie yourself to any hypothesis, even if mainstream, but rather update your probability distributions. Bits of the NT weren't written until long enough after the supposed death of Jesus that people wouldn't have been like, 'Who you talkin' about?' And I doubt they would've cared whether the character existed, like no one cares whether Harry Potter existed, because it's the stories that matter.
0Salemicus
Yes, of course. The least mysterious explanation of Paul Bunyan stories is that there really was a Paul Bunyan. And the closer the real Paul Bunyan hews to the Bunyan of the stories, the smaller the mystery. P(stories about Bunyan | Bunyan) > P(stories about Bunyan | !Bunyan). But just because a story is simple, doesn't necessarily make it likely. We can't conclude from the above that P(Bunyan | stories about Bunyan) > P(!Bunyan | stories about Bunyan).
2CCC
Hmmm. To mess around with equations a bit... what can we say about P(Bunyan | stories about Bunyan) and P(!Bunyan | stories about Bunyan), given P(stories about Bunyan | Bunyan) > P(stories about Bunyan | !Bunyan)? Let's genaralise it a bit (and reduce typing). What can we say about P(A|B) and P(!A|B) when P(B|A) > P(B|!A)? Consider Bayes' Theorem: P(A|B) = [(P(B|A)*P(A)]/P(B). Thus, P(B) = [(P(B|A)*P(A)]/P(A|B) Therefore, P(!A|B) = [(P(B|!A)*P(!A)]/P(B) Now, P(!A) = 1-P(A). So: P(!A|B) = [(P(B|!A)*{1-P(A)}]/P(B) Solve for P(B): P(B) = [(P(B|!A)*{1-P(A)}]/P(!A|B) Since P(B) = [(P(B|A)*P(A)]/P(A|B): [(P(B|A)*P(A)]/P(A|B) = [(P(B|!A)*{1-P(A)}]/P(!A|B) Since P(B|A) > P(B|!A) [(P(B|A)*P(A)]/P(A|B) > [(P(B|!A)*P(A)]/P(A|B) Therefore: [(P(B|!A)*{1-P(A)}]/P(!A|B) > [(P(B|!A)*P(A)]/P(A|B) Since probabilities cannot be negative: [{1-P(A)}]/P(!A|B) > [P(A)]/P(A|B) .[1-P(A)]*P(A|B) > [P(A)]*P(!A|B) ...which means that either (1-P(A)) > P(A) or P(A|B) > P(!A|B), and quite possibly both; and whichever of these two inequalities is false (if either) the ratio between the two sides is closer than the inequality that is true. To return to the original example; either P(Bunyan | stories about Bunyan) > P(!Bunyan | stories about Bunyan) OR P(!Bunyan) > P(Bunyan). Also, if P(Bunyan | stories about Bunyan) > P(!Bunyan | stories about Bunyan) is false, then it must be true that P(Bunyan|stories about Bunyan) > P(Bunyan).

You left out the 'magical' part of my question. If magical beings exist(ed), then everything becomes more mysterious. That's partly why we don't pester JK Rowling about what extra-special boy Harry Potter was based on. We don't even suspect comic superheros like Batman, who has no magic, to have been based on a real-life billionaire. We certainly don't have scholars wasting time looking for evidence of 'the real Batman.' Modern stories of unlikely events are easily taken as imaginings, yet when people bucket a story as 'old/traditonal', for some people, that bucket includes 'characters must've been real persons', as if humans must've been too stupid to have imagination. https://en.wikipedia.org/wiki/Fakelore

I guess you mean that we could and it wouldn't be obviously silly, with which I agree. But, for what it's worth, it never crossed my mind to assume that Harry Potter was based on any specific non-magical boy. The characteristics he has that aren't essentially dependent on story-specific things (magic, being the prime target of a supervillain, etc.) seem pretty ordinary and not in any particular need of explanation. I wouldn't be astonished if it turned out that there was some kid Rowling knew once whom she used as a sort of basis for the character of Harry Potter, but I'd be a bit surprised. And if it did, I wouldn't expect particular incidents in the books to be derived from particular things that happened to that child. In particular, I wouldn't say that the simplest (still less the most likely) explanation for the Harry Potter stories involves there being some non-magical child on whom they are based. I don't think any of this has much bearing on whether the simplest explanation for stories about Jesus, Muhammad, the Buddha, Zeus, etc., involves actual historical characters on which they're based. The answer to that surely varies a lot from case to case. (FWIW I'd say: historical Jesus of some sort likely but not certain; historical Muhammad almost certain; historical Buddha likely but not certain; historical Zeus-predecessor very unlikely. But I am not expert enough for my guesses to be worth anything.)
0Jade
Historical Muhammad not certain: http://www.wsj.com/articles/SB122669909279629451 . Of course, people have set about trying to protect minds from a 'fringe' Bayesian view: "Prof. Kalisch was told he could keep his professorship but must stop teaching Islam to future school teachers." In case anyone missed it, Richard Carrier explicitly used Bayes on question of historical Jesus. I don't know if Kalisch used Bayes, but his language conveys intuitive Bayesian update. The bearing of fictional stories is simple: calculate probabilities of historical X based on practically 100% probability that human imagination was a factor (given that the stories contain highly unlikely magic like in known-to-be fiction stories, plus were written long after X supposedly lived). Note that that still leaves out probabilities of motivations for passing fiction as nonfiction like Joseph Smith or L. Ron Hubbard did. Once you figure probabilities including motivations and iterations of previous religious memes, it becomes increasingly unlikely that X existed. Paul Bunyan, AFAIK, wasn't based on previous memes for controlling people, nor were the stories used to control people, so I wouldn't be suspicious if someone believed the stories started based on someone real. When people insist religious characters were real, OTOH, I become suspicious of their motivations, given unlikelihood that they examined evidence and updated Bayesian-like. @Salemicus: Citation for "We do ask JK Rowling what non magical boy inspired Harry Potter"?

I did say almost certain. My impression -- which, as I said above, is no more than that and could easily be very wrong -- is that the Jesus-myth theories require less "conspiracy" than the Muhammad-myth ones.

Then why don't you just point to evidence of his existence being more likely than others'?

You don't count the Koran as "intact own writings"? :-) Yes, I am well aware that it was compiled quite some time after his death from a collection of records and that, by tradition, Muhammad was illiterate. The Arab society around VII century wasn't big on writing -- the cultural transmission was mostly oral. However external sources mention Muhammad already in 636 AD.

You're referring to the phrase "many villages were ravaged by the killing of the Arabs of Muhammad", written after Muhammad's supposed death, "Arabs of Muhammad" meaning 'Muslims' the way "people of Christ" means 'Christians'. That Muslims and Christians existed doesn't mean the characters they invoked to justify violence, supremacism, etc. existed as actual humans. Criteria for considering Muhammad and Jesus near certain are so lax, we'd have to consider some Greek/Roman gods near certain.

So you're arguing that by 632 the violent and supremacist Arab hordes were justifying their violence and supremacism by inventing an imaginary prophet who lived merely a few decades before (so some of "his" contemporaries were still alive). Because they were so tricksy they made him not a terribly appealing character -- an illiterate merchant's apprentice who married a cougar and then went a bit crazy -- and attributed to him a whole book of poetry clearly written while on acid. And hey -- it worked! Their creation (I guess it was a joint effort -- takes a village and all that..?) was so successful that it caused the fastest massive conquest in human history. An interesting theory.

The criteria for the historicity of Greek/Roman Gods and Muhammad/Jesus are not the same. The Roman Gods are for the most part just Romanized versions of Greek Gods. If you examine the different characteristics closely, then the Greek Gods have much in common with Gods in the pantheons of other Indo-European peoples. For example Zeus is the God of Thunder, Thor is the God of Thunder in Germanic mythologies, and Perun serves the same purpose in Slavic mythologies. Based on these similarities you can trace these stories to the stories of some common ancestral Gods of the old Indo-European nomads on the steppes of Russia and the Ukraine... So these stories are so ancient that any link to anyone living whether man or whatever is highly unlikely. However stories of Jesus and Muhammad are much more likely considering since they occured at times when writing was already invented and shortly after their death, we can see stirrings of historical events linked to them. With Jesus, we have historical writing of him maybe 50 years after his death, including by his enemies. So a historical figure of Jesus is highly likely, although the miracles and stuff attributed to him are made up. With Muhammad the probabilities are even higher. Shortly after his death, there were conquests of neighboring lands done by people who were saying they were his friends (meaning they saw him live). While most of the stories about him are probably highly exaggerated, there most likely was a historical Muhammad.

I really am having trouble doubting my conviction in rational thought. I can't visualize an alternative. I can visualize an alternative to my atheist philosophy though, since if God descended from heaven and handed me a bunch of concrete evidence that He exists, I wouldn't say 'ah, rationality was wrong.' I would say 'Oh, so you exist. I'll eat my hat on that one and concede that my confidence in your non-existence has been defeated, but to be fair until just now you've given me no rational reason to believe in you.' I'm a rational atheist because all of t... (read more)

Well, imagine the world was such that "rational thought" (whatever you mean by it) tended to result in incorrect beliefs, and a different type of thinking (say, choosing positions randomly) always achieved better accuracy. You can't fool it either; pretending to choose beliefs randomly won't work unless you actually believe them.

There is a God/simulator, and he inspects your thought processes, making the world such that rational thinking fails.

For a person who already escaped from religion a thought about "What general strategy would a religious person have to follow in order to escape their religion?" is like a thought about how to make all people on Earth stop eating meat for a vegetarian person. Not a very constructive thought. If one starts thinking about such general strategy then one implicitly sets a goal to somehow assist all religious persons to escape from their religion. But that kind of goal is not necessarily a good one :) Instead, a person who already (or from the start) escaped the religion, can spend that time to look for more people with similar minds.

It seems to me that in our civilisation we have a quite nice way of dealing with deficiency of faith's crises - assuming the narrative of epistemological societal progress the people with poor epistemic hygiene, along with a smaller mix of those with a better one die off and a new generation is generally more able to look at the issues with a fresh set of eyes.

Not sure however how true it is that accurate memes tend to live and propagate - there are quite a few cases that are still disputed despite being settled for hundreds of years, although I may be looking at not big enough time frame here.

Saint Peter of Verona, patron saint of inquisitors, practiced this method when dealing with suspected heretics. By allowing himself to have a crisis of faith when confronted with the sincerity of his opposition, his beliefs came out stronger in the end and we're often persuasive. Saint Peter not only never lost his faith, but through his example, inspired his assassin to devote his life to the Church.

I suggest instead finding an unforgivable sin within the religion you are seeking to escape. Then committing that sin gives you a personal incentive to bui... (read more)

It seems to me that a rationalist provisionally believes that which is supported by the evidence, by the rationalist's experience, and by logical demonstration/argumentation. If there is no such rational basis to believe in a particular religion, it is not clear to me why the rationalist would need any sort of trick to escape from it. It seems to me that deciding what belief you want to have and then tricking yourself into believing it via a ritualistic act rather than via an examination of the evidence, etc., (in other words, following the advice given in your post) could be considered a cardinal sin of (epistemic) rationality.

Thank you! So, the path of purposeful self-deception is not the road to higher rationality, no matter how well it happens to work. To use the monkey riding on the tiger analogy for human cognition, I wonder which is more effective. The monkey putting the tiger in a pen and swinging through the trees alone...Or the monkey that ties a steak to a stick and rides the tiger.
0g_pepper
Correct I suspect the monkey is better off putting the tiger in a pen and swinging through the trees alone - with a steak and a stick it is just a matter of time before the monkey loses control of the situation and becomes a side dish to the steak. Similarly, trying to harness self-deception to lead one to truth/rationality is apt to backfire.
0RedMan
Taking the analogy further to a community of tiger riding monkeys...The monkey that waves the steak on a stick in front of some other monkey's tiger probably has a future in marketing. The monkeys who decide to pen their tigers may have a problem, the tigers are still present, may be unhappy about their confinement, and after a time, the monkeys may not watch them as closely as they should... As a case in point, I give you the prevalence of polyamory in the rationalist community. Historically, polygyny has been a feature of insular communities that wanted to become more insular. Is polyamory serving its purpose as a strong social barrier to entry for the high table of the rationalist community, or is it really just pure rationality at work?
1gjm
I don't see how it can be very useful as a "strong social barrier to entry". It's not as if you have to be poly to be accepted as a rationalist, is it?

no one questions the historicity of say Pythagoras

Really?

Here's a newspaper review whose author says Pythagoras "may well be a mythical amalgam of various forgotten sages". The book under review itself says "Sadly, it is now almost universally assumed by classical scholars that Pythagoras never existed". I suspect this is partly tongue in cheek, since the other information I can find doesn't seem consistent with what it says on its face, but if it's a joke I think it's the sort that depends on not being too far from the truth. Here's... (read more)

Which wasn't Christian while it was doing the conquering.

Fair point: Christianity in Europe is more "persuade the ruler and others will fall into line" than "spread by the sword". (Though IIRC there's some reason to think that the ruler was willing to be persuaded partly because substantial fractions of his people already had been.)

The problem with faith is that for many people it has become a part of their identity. The brain cells are intertwined and when someone attacks their faith, their self-protection mechanism kicks in and their rational thinking turns off.

It's basically like Plato's Allegory of the Cave, where prisoners choose to disbelieve the real world and go back to their own fake reality.

About ten years late to the party here, but regarding Aumann, I think you do him an injustice - he is well aware of the conflict between rationality and God. Here is an interview with him that goes in depth into these issues:

http://www.ma.huji.ac.il/~hart/papers/md-aumann.pdf?

He says: "Religion is an experience, mainly an emotional and aesthetic one. It is not about whether the earth is 5,765 years old. " He goes into more detail. For him, the question of whether or not god really exists is almost irrelevant to his religion. He then delves int... (read more)

Yep; in the time since this was written, the LW community has gone pretty heavily in the direction of "let's figure out how to reclaim the coordination and community benefits of religion separately from the weird belief stuff", and (imo) done pretty well at it.

For me, I'd already absorbed all the right arguments against my religion, as well as several years' worth of assiduously devouring the counterarguments (which were weak, but good enough to push back my doubts each time). What pushed me over the edge, the bit of this that I reinvented for myself, was:

"What would I think about these arguments if I hadn't already committed myself to faith?"

Once I asked myself those words, it was clear where I was headed. I've done my best to remember them since.

Why would this question be relevant? Let's say that the answer is "I would think that the arguments in favour of religion are stupid". What is that supposed to prove?
3orthonormal
I used to believe, as do many Christians, that an open-hearted truthseeker will become convinced of the existence of the true God once they are exposed. To say otherwise makes missionary work seem rather manipulative (albeit still important for saving souls). More importantly, the principle is well attested in Christian thought and in the New Testament (Jesus with Nicodemus, Paul with the Athenians, etc). There are and have been world religions that don't evangelize because they don't have the same assumption, but Christianity in particular is greatly wounded if that assumption proves false.
1Jakub Supeł
Oh, so then the question should be "What would I think about these arguments if I hadn't already committed myself to faith and I were an open-hearted truthseeker?". Your claim is that: 1) such a person should consider arguments for the Christian faith to be good, on balance (otherwise "Christianity is greatly wounded"), and 2) such a person often would not consider arguments for the Christian faith to be good. Why do you believe (2)? That is, how can you know what a sincere seeker is going to think of any particular argument? Or, even worse, about all the arguments so that they can decide which theory is more probable on the balance?  I met unbelievers who found some arguments convincing and others who found them unconvincing, but there is no way for me to know if any of them were open-hearted truthseekers. If doctrine (1) is true, it's just not an empirically verifiable doctrine, since there is no observation by means of which you could determine even your own sincerity, much less that of others. https://www.reasonablefaith.org/writings/question-answer/is-gods-existence-evident-to-every-sincere-seeker

Why do you consider religious faiths to be obviously untrue? "They would be child's play for an unattached mind to relinquish, if the skepticism of a ten-year-old were applied without evasion." Why do you consider the questions of a ten-year old to be unaswerable except through evasion? On the contrary, such questions are almost invariably easily answerable to anyone who has the slighest knowledge about philosophy of religion and the doctrine of their particular religion. I would be silly to be guided by the questions of a 10-year old instead of the a... (read more)

I came back to this post to draw inspiration from it and found several issues with it, that I now spot as a much older and more mature adult, almost 30.

 

  1. God and other spiritual or/and religious topics are placeholders to be tabooed, so there can be many individual beliefs behind them. What is sound? Is it the wave or the phenomenon in the brain? Same with God. Every theist has his or her own little bubble of belief. 

    We cannot refute the ARGUMENTS for God easily, we have to refute the THINKING. 

    That is what the article indeed argues and tries
