Their judgment was based more upon blind wishing than upon any sound prevision; for it is a habit of mankind to entrust to careless hope what they long for, and to use sovereign reason to thrust aside what they do not fancy.

-- Thucydides, Greek Historian, ca. 5th century BCE (Book IV, 108)

I like Thucydides for the way he tries to explain history in terms of real-politik, people, their drives and especially without including the gods in an explanation, somewhat similar to Hippocrates.

Interestingly, a modern version of this appeared in Neal Stephenson's Anathem:

Never believe a thing simply because you want it to be true

where it's called Diax's Rake.

Anathem is a great book, I'd like to add, and quite well aligned with many of the LW themes.

Secondly, Anathem isn't actually aligned with LW themes at all. It might appear that way at the beginning, but Stephenson undoes all of it with the spoiler twist at the end.

If anything of the classical supernatural existed, it would be a branch of engineering by now.

The Salvation War Web Original trilogy is based on this premise. And boy does it makes good use of it.

I've just been reading it. Oh dear... this series looks to be fun and really really bad. "Good Omens" (Pratchett and Gaiman) is an excellent book along such apocalyptic lines.

3SilasBarta14y

Now that you mention it, this is kind of the premise of the Star Ocean series. It has "symbology" (as it's called in the third installment, Till the End of Time), which is basically the ability to manipulate nature to do "magical"-seeming things by formation of particular symbols. The people in these worlds harness this capability for standard engineering purposes: they build air-conditioning units that draw their coldness from application of specific symbols. The plot of End of Time revolves around a professor combining symbological powers with those of genetics.

0fortyeridania14y

People have cited some very modern inventions, but ever since the first invention, people have been inventing things that were previously relegated to magic. I mean, what else is technology?

6gwern14y

Some technology is for replacing things ascribed to magic. But most technology is fulfilling needs that a wizard doesn't know he has, or is there to solve a need or problem that wouldn't except for some other bit of technology. Look at a few thousand (out of the millions of existing) patents. How many of them have a direct analogue in magic such that their utility really is something 'previously relegated to magic'? - not vaguely falling in a general class of functionality which you once saw a spell kinda-sorta like. For example. Recent news about an environmentally friendly rocket fuel made out of just nitrogen and oxygen. This is a very modern invention. It's very useful. What magic does it replace? 'Oh, rocket fuel replaces flying on a broomstick!' Ah, but I wasn't talking about rocket fuel in general and certainly not rockets+rocket-fuel, because this invention was not of 'rocket fuel in general'. This invention was of a particular kind of rocket fuel. What magic does this particular kind of rocket fuel replace? The answer is none. Flying magic is conceived of as intrinsically environmentally friendly. Harry Potter never asks himself how he will pay for the bioremediation of the hydrochloric acid left in the wake of his broomstick. Take a look at Kevin Kelly's discussion of sparkcatchers. What magic is this technology replacing? This isn't even particularly esoteric stuff like I could start pulling out from biology or chemistry. (What wizard - or author - ever had the imagination to think of bacteria glowing green like fireflies?) This kind of statement reminds me of an upvoted quote here somewhere which went 'since when has the majority ever been right about anything?' This irritates me, because the majority is right. Of the infinite class of propositions the majority holds, most are right, and the ones the majority has been wrong about, like geocentrism, have approximately measure 0. It's right about everything else. The majority in the room I am in think

1soreff14y

Very much agreed. By the way, this one one of the points W. Brian Arthur makes in The Nature of Technology which I recommend as a well written exposition of quite a number of the dynamics in technology development. One very broad range of technology which has no analog to magic is high precision instrumentation. There are very few situations in daily life when I need to know a measurement to within 0.1%, and they are many technological and scientific situations where that knowledge is necessary.

1gwern14y

Actually, Arthur is already on my reading list. ;) I think I must have seen him recommended before by Kevin Kelly or perhaps Don Ihde. I was going to point out that another good example is all the sensory modalities that science knows of, like electromagnetism in all its forms and frequencies, or gravity itself, but I thought that they were too arguably close to magical 'second sight' or chi skills like sensing someone nearby.

0shokwave14y

You have to be careful that you don't go from "the majority is right in most cases" to "the majority is right in this case" without good reason. Prior to any information about this case, sure, it's a good guide. But if you have reason to believe that this case isn't a trivial inference from overwhelming direct observational evidence, then the majority is much less of a guide. When it comes to a socially-accepted conclusion, a severe dearth of evidence, and motivations to hold a certain point of view, 70-90% - the majority - get it wrong. On the phrase "since when has the majority ever been right about anything?": on most points of difference, the majority has been wrong first and right only later. It is easy to look at only the points of difference: when it comes to points of similarity, you are part of the majority, and so you're not really interested in knocking them down. Perhaps a better formulation would be "since when has the majority ever been right about anything that isn't simultaneously important and obvious ?" The problem with saying is that most are boring. On the class of interesting propositions, the majority does not have a good track record.

Repeat?

9Richard_Kennaway14y

I only judge something as a repeat if it's already appeared in a quotes thread. Sometimes it's worth pulling out something quoted in the middle of a discussion and presenting it here.

1Kaj_Sotala14y

Apparently, yeah. Not in a quotes thread, though.

[-]torekp14y190

Idealists of all schools, aristocrats and bourgeois, theologians and physicians, politicians and moralists, religionists, philosophers, or poets, not forgetting the liberal economists - unbounded worshippers of the ideal, as we know - are much offended when told that man, with his magnificent intelligence, his sublime ideas, and his boundless aspirations, is, like all else existing in the world, nothing but matter, only a product of vile matter.

We may answer that the matter of which materialists speak, matter spontaneously and eternally mobile, active, productive, matter chemically or organically determined and manifested by the properties or forces, mechanical, physical, animal, and intelligent, which necessarily belong to it - that this matter has nothing in common with the vile matter of the idealists. The latter, a product of their false abstraction, is indeed a stupid, inanimate, immobile thing, incapable of giving birth to the smallest product, a caput mortuum, an ugly fancy in contrast to the beautiful fancy which they call God; as the opposite of this supreme being, matter, their matter, stripped by that constitutes its real nature, necessarily represents supreme nothingness.

"Anyone who believes that the theory of evolution implies moral darwinism, and who also believes in the theory of gravity, has a moral duty to go jump off a cliff." -- Ari Rahikkala

2JenniferRM14y

Is there anyone who actually believes in moral darwinism under that self-description, or is it just a straw man position that people like to claim as the underpinning of the ideology of people they don't like? When I tried to google the term I found the book Moral Darwinism: How We Became Hedonists which is described thusly in a five star review:

6Tyrrell_McAllister14y

I think that the quote is best read as a critique of any appeal to nature. Maybe you don't see such brazen appeals to nature in careful arguments, but they seem common enough in informal arguments. Many people really do seem to think that you've made a substantive point about what we ought to do when you point out that something happens "in nature". For example, I knew someone once who was uncomfortable with tolerating homosexuality, but who felt obliged to seriously reconsider his position when he learned that animals sometimes exhibit homosexual behavior. I was in the strange position of trying to explain why he ought not to be persuaded by that argument, even though it led him to what I thought was the right conclusion.

1Blueberry14y

Did you then tell him about chimpanzee war, murder, and infanticide? The appeal to nature is very common, and I'd rather get rid of that than change someone's mind about same-sex behavior, which seems to be a terminal value difference anyway.

5SilasBarta14y

So, Wiker thinks that the eventually-dominant (?) Epicurean movement staged a deliberate 2-millennium (?) campaign to get a 60s-style social revolution (?) going, and thereby steal credit (?) for scientific advancement from the Church, which was doing so well at it (?) for the first 1500 years. Before reading it: what are the odds Wiker has marshaled enough evidence to even get that hypothesis on the radar? Oh, and check this out from the description: Yeah, we sure don't have any evidence of a Greek culture practicing infanticide, do we? Edit: Also, the review you refer to is by a "Phillip Johnson", who looks to be this Phillip Johnson, founder of the Intelligent Design movement.

2JenniferRM14y

I think that you're agreeing with me? My point was that Wike clearly has an axe to grind and was attributing belief in "moral darwinism" to people who don't even know what it means. You're logically taking apart the theory I was quoting... thus we're in agreement... or not? Or something. The thing I was puzzled by was the way the original quote had a surface layer of congruence (darwinism, suicide for stupid people, etc) but was difficult for me to coherently parse when I tried to work out the implications and examine the logic that inspired it. I came up wanting when I did that, and that lead me to question whether the ideas themselves were well grounded. If not, where did the ideas even come from?

2SilasBarta14y

Yes, we're in agreement. I was just shocked by how bizarre the claim is, given how many improbable pieces he's stitched together. I think Johnson -- or Wiker, if that's what the book really argues -- came to that belief by fitting his own view sympathetically into a larger narrative, and found it convenient to stretch it as far back in time as possible. In fairness, when reading about Epicurus, a lot of his ideas do match modern post-60s beliefs, but there isn't a common demographic that endorses the whole package.

[-]DSimon14y160

When I was 14, my father was stationed in Japan. I went rock climbing with this kid from school. He fell and got injured, and I had to bring him to the hospital. We came in through the wrong entrance, and passed this guy in the hall. He was a janitor. My friend came down with an infection, and the doctors didn't know what to do. So they brought in the janitor. He was a doctor. And a Buraku - one of Japan's untouchables. His ancestors had been slaughterers, gravediggers. And this guy knew that he wasn't accepted by the staff, didn't even try. He didn't dress well. He didn't pretend to be one of them. People around that place didn't think he had anything they wanted, except when they needed him - because he was right, which meant that nothing else mattered. And they had to listen to him.

Yeah, I really thought that was true at some point... but as it turns out, being good at fixing broken Windows computers hasn't made me respected, just commodified. :-)

[-]brazzy14y160

The necessity for marking our classes has brought with it a bias for false and excessive contrast, and we never invent a term but we are at once cramming it with implications beyond its legitimate content. There is no feat of irrelevance that people will not perform quite easily in this way; there is no class, however accidental, to which they will not at once ascribe deeply distinctive qualities. The seventh sons of seventh sons have remarkable powers of insight; people with a certain sort of ear commit crimes of violence; people with red hair have souls of fire; all democratic socialists are trustworthy persons; all people born in Ireland have vivid imaginations and all Englishmen are clods; all Hindoos are cowardly liars; all curly-haired people are good-natured; all hunch-backs are energetic and wicked, and all Frenchmen eat frogs. Such stupid generalisations have been believed with the utmost readiness, and acted upon by great numbers of sane, respectable people. And when the class is one's own class, when it expresses one of the aggregations to which one refers one's own activities, then the disposition to divide all qualities between this class and its converse, and to cram one's own class with every desirable distinction, becomes overwhelming.

[-]SilasBarta14y230

I was actually starting another article that presents a solution (well, a research program) for qualia. [1] The idea is this:

The concept of qualia becomes mysterious when we have a situation in which sensory data (edit: actually, cognition of the sensory data) is incommensurable (not comparable) between beings. So the key question is, when would this situation arise?

If you have two identical robots with idential protocols, you have no qualia problem. They can directly exchange their experiences and leave no question about whether "my red" is "your red".

But here's the kicker: imagine if the robots don't use identical protocols. Imagine that they instead simply use themselves to collect and retain as much information about their experiences as physically possible. They optimize "amount I remember".

In that case, they will use every possible trick to make efficient use of what they have, no longer limited by the protocols. So they will eventually use "encoding schemes" for which there is no external rulebook; the encoding is implicitly "decompressed" by their overall functionality. They have not left a "paper trail" that... (read more)

9JenniferRM14y

Before finishing (or perhaps as a sequel?) you should make sure to watch Cristof's Koch's "neural correlates of consciousness" talk. He's been giving variations on this talk for something like 10 years that I know of and its pretty polished. Its gotten better over the years and the speaker is the source of my current working definition of consciousness (quoted below). Which is not about language I/O and compression but about internal experiences themselves and what systems implement them. The core insight is that you can show someone a visual trick (like the faces or goblet image) and you can go back and forth "seeing different interpretations". When you're in one or the other state "internal state" this is you having different kinds of "qualia", and presumably these distinct perceptual states have "biological correlates". Manipulation of these internal mental states and study of the associated physical systems become the "object of study" in order to crack the mind-body problem. Once you've got the neural level you can ask about high level issues like algorithms or ask about deeper mechanisms like neurotransmitters and genes and so on. Full understanding would imply that we could create mutant "zombie mice" and that they would have no qualia (of certain sorts) and be incapable of whatever behavior was "computed" in a way that involved (that sort of) qualia. Ideally we would have a theory to predict and and explain such phenomenon and perhaps we'd be able to invent things like a pill that lets you "become a p-zombie" for an hour (though I suspect part of that would involve shutting down enough memory formation processes that you would not be able to remember the experience except via something external like videotape). The Q&A has much more sophisticated objections/questions than you usually get on the subject of minds. The final question ends with Koch's working theory which sounds about right to me. Quoting Koch when asked why he thinks bees are probably consc

3SilasBarta14y

Thanks for the pointer! This will help me to connect my speculations to the existing literature. Any text version/transcript of this lecture, or paper that explains the points in the talk?

0JenniferRM14y

My summary above cuts to what I think is the core insight about focusing clearly and experimentally on exactly the elements of interest: consciousness and neurons. The talk itself is a summary of the main points of many papers with different points and some demonstrations of the experimental manipulations. The talk itself (rather than the intros) starts about 4 minutes in. I recommend just watching it. Koch is a pretty good speaker and this is sort of his "dog and pony show" where he summarizes an entire research program in a way that's been iteratively optimized for years. Your 60 minutes will not be wasted :-)

1Oscar_Cunningham14y

Up voted, looking forward to you posting some of these in-progress articles. Should: Be vice-versa?

Thanks! And yes it should, I'll correct that.

0WrongBot14y

This seems to match up with an argument I made against writing oneself into the future, though I think your formulation is more general. I'm certainly quite interested in hearing more on the subject; I think you're headed in a good direction.

4SilasBarta14y

Thank you much, and I definitely see the similarity with what you posted. I may indeed be running into the problem of letting "good enough" become the enemy of "at all". I'll try to get these articles up in some presentable form soon.

2cousin_it14y

The drafts you've been posting lately are interesting to me, and I'd like to see them fleshed out into top-level posts. I would also suggest adding external material and references to give more context to your thought experiments.

0SilasBarta14y

Thanks. But that's one of my difficulties. I read a lot of stuff and so these ideas just "come together". I don't even know if there is a source that agrees with this idea. As it stands now, the only sources I believe I'd be able to cite are some of Gary Drescher's discussion of qualia, and the information-theoretic basics of how compression works, and what makes it more or less effective. Any suggestions (specific suggestions) for how to find the external references that would be relevant to this topic or the other one's I've posted recently? By the way: I started keeping a list of planned top-level articles on my Wiki page.

1NihilCredo14y

I 'get' the other two, but the red-silk analogy eludes me.

2Richard_Kennaway14y

I have heard of a blind man comparing red (as he had heard of it) to the sound of a trumpet.

0NihilCredo14y

Hmm... can a blind man possess synæsthesia? It seems possible if the source of the blindness is in the eye rather than the brain.

4Jonathan_Graehl14y

More likely color-words as concepts exist in the brains of blind people because there are interestingly different distributions of other directly meaningful concepts associated in proximity with others' usage of the color-words, and with actual objects in the world (presuming that their color is sometimes described to you). I think Richard put this very well when he said "as he had heard of it".

2Blueberry14y

Probably. A color-blind person can.

1Blueberry14y

Me too. Silk is more like beige or cream color. How can you describe red without talking about fire?

3KrisC14y

Or this infographic from Information is beautiful. The texture of silk is smooth and easily slips from the grasp. It is exciting and sensuous as a fabric. Anger, courage, love, heat, and passion, according to the chart. Perhaps it might be easier to read them the referenced chart's correspondences.

9twanvl14y

That infographic would have been much better as a regular table, instead of this circular thing. It seems to me as if it is not intended to be actually used, only to look nice.

[-]Richard_Kennaway14y100

It's a dreadful graphic. No information leaps out at the viewer, you have to hunt through two tables for the meanings of the letters and numbers. It takes an effort to find the letter for any given block, or to find the block for any given letter, in radii far from where the letters appear. It's difficult to tell apart yellow and gold, or grey and silver: the key only serves to highlight how indistinguishable the colours are.

And since this graphic does not work, I cannot see it as beautiful. It is an ugly sacrifice of function to superficial prettiness.

1cupholder14y

Agreed. I wish they'd stick to calling hard-to-read graphics like this 'visualizations' - the word 'infographics' implies a graphic designed to efficiently display information. The worst part is it wouldn't be hard to improve the graphic. They could drop the annoying 84-item list and just directly write the emotions in the 84 slots around the circle instead of using numbers. Enlarge the circle and blow up the font size a bit - then they can put the A to J list of cultures into the empty middle of the circle so you don't have to keep looking off the side to cross-reference it. That'd help, even if it wouldn't fix it. Edit - I see that when they used that infographic as their book's cover, they gave up on the idea of making it a real infographic and just made it into a pretty flower!

0Blueberry14y

So looking at numbers 31, 2, and 46, a friendly AI should be orange and blue... I don't associate red with smoothness, or silk with any of those emotional qualities.

2wedrifid14y

Are you sure about that? Your emotions don't ask you for permission before they make associations.

-1Blueberry14y

I can't tell if this is wordplay based on the ambiguity in the quoted sentence (in which case, I like the joke :) ) or if you're serious. If you're serious, then yes, I'm sure: while emotions may not ask me for permission, I'm aware of what they're associated with.

Their judgment was based more upon blind wishing than upon any sound prevision; for it is a habit of mankind to entrust to careless hope what they long for, and to use sovereign reason to thrust aside what they do not fancy.

-- Thucydides, Greek Historian, ca. 5th century BCE (Book IV, 108)

I like Thucydides for the way he tries to explain history in terms of real-politik, people, their drives and especially without including the gods in an explanation, somewhat similar to Hippocrates.

Interestingly, a modern version of this appeared in Neal Stephenson's Anathem:

Never believe a thing simply because you want it to be true

where it's called Diax's Rake.

Anathem is a great book, I'd like to add, and quite well aligned with many of the LW themes.

No love for Wizard's First Rule?

0[anonymous]14y

I have to disagree on two counts. First, Diax's Rake is explicitly a reference to Thucydides, (or, more spoilerifically, Thucydides' "referenced" Diax for some value of reference), so it's not really interesting that it appeared in Anathem. Secondly, Anathem isn't actually aligned with LW themes at all. It might appear that way at the beginning, but Stephenson undoes all of it with the spoiler twist at the end.

0djcb14y

Hmm.. i can't remember the specific reference to Thucydides from the book, and I don't have it handy right now... did the book mention him? I just found the parallel quite interesting. Regarding the other point, I meant 'aligned with LW themes', that is discusses many of the same things that are discussed here -- and in many cases seems to agree. Not always - but apart from the parallel universe mixups which are a bit... suspect, I got the idea that NS has been lookin at LW (well, OB) and similar sources.

Shame leads to a variant on guessing the teacher's password-- an effort to not piss people off, without asking them what might be problematic. After all, you're supposed to know better than to make that mistake.

3xamdam14y

"The shameful does not learn" - Talmud I agree with your point, but I do not think the emotion should be dispensed with altogether, if that's really possible. I think you can separate social embarrassment, which in this context is counterproductive, from deep very personal private embarrassment of having been stupid.

[-]WrongBot14y120

For an even somewhat rational person, pain is far stronger than necessary as a warning sign. As someone generally concerned with my own body's welfare, the mental equivalent of popping up a politely worded dialog box would be sufficient. I find that shame is likewise overkill for solving this problem.

5rwallace14y

Personally, I don't mind pain being a strong enough warning that it's hard to ignore. I can see the need for that. I think the problem with pain is that it's like those stupid car alarms. You know the ones that should be programmed to turn off after five minutes because any good they might do will have been done by then if it's to be done at all, but they actually keep going all night? That's what pain should have: a way of saying, after some appropriate enforced time delay, fine, I've got the message, I'm doing everything I can about the problem, you can stop now.

4SilasBarta14y

I can't. I've had problems with pains that are demonstrably unrelated to any threat to bodily integrity and for which there is no known technique that removes it. If pain were limited to real threats, I'd agree, but it's not. So it's not even an issue of "yeah, I get the message, you can stop reminding me"; often times, there is no message to be given, just suffering.

3Blueberry14y

Have you never been tempted to push ahead doing something you want, and ignored a minor pain? We'd just ignore pop-up boxes if we were in the middle of something we considered important.

0WrongBot14y

Absolutely. But this is not a way in which pain is superior to a pop-up box. If the pop-up box that replaced intense pain had alarms and flashing lights attached, and the one for more minor pains did not, I would pay attention to the alarms and flashing lights.

[-]DSimon14y140

Speaking in terms of real pop-up boxes, you might be surprised at how easy it is for people to ignore the content of even the most blaring, attention-grabbing error messages.

A typical computer user's reaction to a pop-up box is to immediately click whatever they think will make it go away, because a pop-up box is not a message to be understood but a distraction from what they're actually trying to accomplish. A more obnoxious pop-up box just increases the user's agitation to get rid of it.

As rationalists, we try hard to avoid falling into traps like these (I'm not sure if there's a name for the fallacy of ignoring information because it's annoying, but it's not exactly a high-utility strategy), but part of the way we should do that is to design systems that encourage good habits automatically.

I like Firefox's approach; when it wants you to choose between Yes or No on an important question ("Really install this unsigned plugin?"), it actually disables the buttons on the pop-up for the first 3 seconds. You see the pop-up box, your well-honed killer instinct kicks in and attempts to destroy it by mindlessly clicking on Yes so you can get back to work already... but that doesn't work, you're surprised, and that jolt out of complacency inspires you to actually read the message.

I suspect a "Hey, have you noticed that something has penetrated the skin of your left foot?" warning might benefit from having the same mechanism.

5WrongBot14y

I appear to be a mutant: I always read pop-up boxes. By all means, please adapt my analogy to something that you would actually pay attention to.

3sfb14y

That doesn't seem a lot better - I know what it wants me to do with an unsigned plugin prompt - review the site, verify the download hash, review the plugin source code, look for reviews of the plugin, author, site... What I actually do is wait 5 seconds, then click "yes do it" as soon as possible. So the utility is ... well intentioned, but still ineffective.

1DSimon14y

It's true that it's less than perfectly effective, but it serves some purpose: I almost always install plugins from the Mozilla plugin site, where a rating is immediately available, and where a virused plugin would probably get removed very quickly. Under those conditions, I know that I'm fairly safe just installing it anyways. However, a malicious site could attempt to infect my browser by installing a plugin, which is where the timer comes in handy. It could even attempt to hide the plugin dialog with lots of other useless dialogs ("Really submit this comment?" Yes. "Really really submit this comment?" Yes. "Really really REALLY submit this comment?" Yes. "Install this plugin?" Yes. Oh, hold on, wait! Crap.) More generally, timed dialogs are helpful because they increase the chance that you notice what it is you're confirming. If you know you're doing something risky and want to do it anyways, so be it... but at least you know what it is you're accepting, and are given a greater opportunity to back out if you are surprised by the level of risk.

It seems pretty clear to me that this was not true in our ancestral environment. It may be the case in our present artificially benign environment however.

1WrongBot14y

That is precisely what I mean; but also note that there are circumstances in the ancestral environment in which pain is entirely useless, such as when one has been mortally wounded. So even in the worst case we can do better than pain, and in the current case I suspect we can do much, much better.

1SilasBarta14y

Evolution has the problem of path-dependence, though. Once the "don't do that" / "pay attention to that" mechanism builds up slowly over many generations, it cannot refactor in such a way that it surgically cuts out the internal feeling of pain in precisely those circumstances where, "hey, might as well give up".

0mattnewport14y

It's hard to see what reproductive benefit there would be to reduced suffering when dying either so there is unlikely to be any evolutionary pressure in that direction.

0xamdam14y

Thanks for the explanation. I like the argument, but still willing to play the devil's advocate: popup box is nice when you're paying attention, but it does not produce learning. Imagine working on a plant where a wrong move can cause a serious injury. Popup boxes will not produce the muscle memory needed to navigate. I would argue this strongly about pain, but I am not sure how well the analogy transfers to mental errors.

2WrongBot14y

Well, it would have to be a popup box that interrupts whatever you're currently thinking about. It grabs focus, to continue the analogy. Does pain produce muscle memory? I haven't heard that before.

1xamdam14y

Maybe a popup would be better, but until we can hack our brains the question remains whether you're better off with shame as a learning mechanism. Does pain produce learning? Probably yes. http://www.nytimes.com/1991/08/27/news/pain-and-learning-may-be-close-cousins-in-chain-of-evolution.html?pagewanted=all

1WrongBot14y

To continue the computer analogy, it would have to be a popup box that steals focus, so that you can't do anything else until you acknowledge it's there. Does pain aid in creating muscle memory? I hadn't heard that before.

1red7514y

Should it pop up again if pain increases from mild to strong? Should it pop up periodically when pain is extreme? I'd rather prefer to consciously disable drive to remove pain source, but stay informed of kind and intensity of pain. Edit: AFAIK insects use that kind of pain processing, they react on pain, but they don't get overwhelmed by it.

1WrongBot14y

Sure. The analogy to computers is not a perfect one, because brains don't function like modern computer operating systems. My objection to pain is not that it is uninformative, it's that it's overwhelmingly unpleasant even when we do not wish it to be.

1red7514y

Yes, it can inflict more harm by forcing you into suboptimal decisions. Shame can be alike too. So, I vote for insect-like shame and pain processing, I've mentioned in grandparent.

1sclamons14y

There are cases of people with no sense of pain. Here's an article about it: http://findarticles.com/p/articles/mi_m1200/is_25_170/ai_n26713199/ ...and a link to the primary it references, if you have a subscription to Nature: http://www.nature.com/nature/journal/v444/n7121/full/nature05413.html A relevant quote from the review: "The team's first research subject, a 10-year-old boy, was well known in his community for street performances in which he placed knives through his arms and walked on hot coals. Despite tissue damage, he apparently felt no discomfort." Other mutants for the same gene were similar -- they generally enjoyed showing off their lack of pain by deliberately injuring themselves. One killed himself by jumping off a roof, I believe just after the above article was published (sorry, I'm not really sure where I read that). Living without pain is generally an unhealthy idea. Without visceral negative feedback, humans don't place value on bodily integrity and tend to self-terminate, which is probably why those mutants are incredibly rare. Perhaps once aversion reactions have been formed, knocking out pain receptors would be a good thing. I'd certainly be curious to see if people still avoid injuring themselves if they lose the ability to feel pain AFTER they've experienced it all their lives.

3Cyan14y

They don't. People who develop pain asymbolia from various insults to the brain are not strongly motivated to avoid pain. (And these are people who have functioning nociception, unlike the family described in the article you link.)

2WrongBot14y

Yeah, knocking out pain receptors in children seems like a very bad idea. Pain is unnecessarily harsh if you already have a strong interest in preserving your body; then all you really need is to know that you're doing something bad to yourself, and that's more than enough reason to stop. But for those who are not yet sufficiently rational, like (most) children, it's probably not something to be messed with without serious consideration. It sounds like that kid has some of the worst parents in human history. How do you let your kid get a reputation for self-mutilation and not, y'know, stop him?

2wedrifid14y

Stop your child from getting status for himself and your family? Inconceivable!

0red7514y

Knocking out nociceptors? It's not what I thought about. Knocking them out reduce available infomation to make decisions. I meant deliberate suppression of goal-shifting and brain resource allocation effects of nociceptors activity (in a sense proposed by Marvin Minsky). It is hard to evaluate effects of this change on child's pain aversion behavior, but I can hypothesize that this kind of pain control could be ineffective until "central executive" is sufficiently developed. Edit: In the case of mild pain this way of dealing with it can be exercised on our current brainware.

3apophenia14y

I disagree--perverse incentives. If I was ashamed every time I was wrong, I might be more careful. Or, I might stop admitting I was wrong.

I am stunned by the relatively high mod-points of this exchange. I agree that the quotes are moderately funny. (Albeit the M.S. quote was much more funny in the specific context within the game, but even there it was his white-wash response to an action that earned Shepard renegade points.) Still, I can't see, how all this is related to the "art of human rationality"...

6Rain14y

"Killing is wrong, no matter what," is a very powerful and standard meme for heroes. It is counter intuitive for someone who "loves people" to kill someone. It requires a less-biased assessment of expected utility than is typically performed. That's why I enjoyed the original quote; in the context of the movie, it made sense in the way of typical human failings for him to say no, and his body language and tone highly suggested he would do so right until the end.

6CronoDAS14y

It's also convenient for writers. Imagine what would happen to the Batman comic book series if someone finally got around to putting a bullet through The Joker's brain. (In a Discworld story, it's suggested that "heroes" and Dark Lords have a bit of an understanding: Dark Lords keep on making all of the mistakes on the Evil Overlord list, and heroes keep on letting Dark Lords escape after the day has been saved.)

3wedrifid14y

And nauseating. Don't forget nauseating.

1Christian_Szegedy14y

In my reading, the assessment was funny exactly because it was emotional and therefore biased. That's what use of "son of a bitch" suggested as well.

3Rain14y

Emotion drives value and purpose; logic is compatible with emotion; Spock is a bad example for rationalists.

3fortyeridania14y

It's related because it portrays someone disregarding the omission/commission distinction. Among consequentialists (who seem to be quite common on LW), how something happens is not directly relevant to its moral value. Untutored intuition, in contrast, seems to say that killing is worse than letting die. Therefore, if consequentialism is right about this, then many humans' moral intuitions are wrong in a predictable way. Thus they are biased. Thus they are irrational. Thus this is related to the art of human rationality.

8TheOtherDave14y

The situations in which a habitual killer-of-humans will cause death come up more often than the situations in which a habitual letter-of-humans-die will cause death. If you're a consequentialist who negatively values death, it seems to follow that a habit of killing humans is worse than a habit of letting them die.

1fortyeridania14y

Thank you for pointing out this argument. I'm not sure I agree that "let-die" situations arise less often than "kill" situations. It seems that every moment you have disposable income (i.e. more than you and yours need to survive) involves a choice between saving someone's life and not saving anyone's life.

0TheOtherDave14y

(nods) That's fair. And yes, if it makes sense to classify what I'm doing right now as choosing not to avert avoidable deaths, it follows that my lifestyle is morally worse (from a consequentialist perspective) than that of a poor murderer.

In which case the quote becomes much less categoric.

He was no computer scientist, but he presumably knew a lot about specific non-computer things. The more important those things are, the less important computers are likely to be (relative to computers, that is).

It comes in roughly two main categories - things you ought to read if you want to pursue a worthwhile career in software, and things you ought to read if you want to be a manager or leader. There is some overlap, but this book falls squarely in the second.

Twinkle, twinkle, little star -
I know exactly what you are:
An incandescent ball of gas,
Condensing to a solid mass.

Twinkle, twinkle, giant star -
I need not wonder what you are,
For seen through spectroscopic ken
You're helium and hydrogen.

-- Peter Marshall

(Quoted in Robert Ettinger's "The Prospect of Immortality." Ettinger says that Gene Lund credited it to Peter Marshall. I haven't been able to find a more direct source that confirms this.)

Edit: How do you force a line return so that a poem will read correctly? Thanks, fixed now.

End the line with two (or more) spaces.

Thanks very much.

Excellent! My kids get this version: Twinkle Twinkle little star, We all know just what you are, You're a sun that's far away, Far too faint to see by day Twinkle Twinkle little star, We all know just what you are

Put a double space at the end of the line.

"They never do tests. Not many real deeds either. Oh, conversation with your grandmother's shade in a darkened room, the odd love potion or two, but comes a doubter, why, then it's the wrong day, the planets are not in line, the entrails are not favorable, we don't do tests!" -Tyrian, Dragonslayer

"No, imbeciles! No! Fools and cretins, a book will not make a plate of soup; a novel is not a pair of boots; a sonnet is not a syringe; a drama is not a railway - those forms of civilization which have caused humanity to march on the road to progress.
By all the bowels of all the popes, past, present and future, no! Ten thousand times no!
You cannot make a hat out of a metonymy, and you cannot make a simile in the form of a bedroom slipper, and you cannot use an antithesis as an umbrella [...] An ode is, I have a feeling, too light a garment for the wi

We don't need anyone to tell us what to do. Not Savonarola, not the Medici. We are free to follow our own path. There are those who will take that freedom from us, and too many of you gladly give it. But it is our ability to choose- whatever you think is true- that makes us human...There is no book or teacher to give you the answers, to show you the way. Choose your own way! Do not follow me, or anyone else.

(Assassin's Creed II, Ezio Auditore's speech)

Okay, I'll choose my own way. What else does Auditore say I should do?

This problem of "I want to teach you how to do something by yourself - to start with, do what I say because I say so" seems to apply to teaching children / non-rational people to be more rational, teaching unhappy / non-biologically-broken depressed people (i.e. broken world view, not causatively abnormal brain chemistry) to be happier, as well as dependent people to be more independent. Taking better control of yourself, starting by giving more control to someone else to get you past the initial obstable that you can't get past and onto the proverbial ladder that you can then continue cimbing yourself. It looks like a more legitimate problem than your dismissal gives it credit for.

Why do you care? You should not follow it anyways. ;)

From Give Well:

I think the distinction between “interesting story/hypothesis” and “good case for action” is also chronically underrecognized in the world of giving.

I don't think the problem is limited to the world of giving.

With CJ Cherryh's Foreigner novels, I haven't had that sort of good fortune. However, I think I'm beginning to have a clue to at least one of the aspects of that grammar. What she does, leading up over a number of pages to those sections that in other writers would be identified as infodumps, is carefully build the foundation for a question -- and then, when she writes that section, she answers that question. Which means that by that time the reader is so eager for the information that it doesn't come across as an infodump at all.

I have a few questions.

1) What's "Bayescraft"? I don't recall seeing this word elsewhere. I haven't seen a definition on LW wiki either.
2) Why do some people capitalize some words here? Like "Traditional Rationality" and whatnot.

Man's bodily needs are simple, being comprised under three heads: food, clothing, and a dwelling-place; but the bodily desires which were implanted in him with a view to procuring these are apt to rebel against reason, which is of later growth than they.

-- Al Ghazzali, "The Alchemy of Happiness"

If he were speaking to us through the chronophone, we might hear him continue:

Accordingly, as we saw above, they require to be curbed and restrained by the mathematical laws promulgated by the Bayesian Conspiracy.

How wise it was of Al-Ghazzali to recognize, a thousand years ago, that our bodily desires exist only to induce us, in a rather stupid way, to satisfy our needs.

Once I read about the experiments of a German professor studying the simplest mechanisms of memory formation in primitive creatures. The German did find his simplest mechanisms - generally, Germans always find what they search for. In particular, he put a worm on a narrow board. The worm crawled ahead. Ahead was an electrified wire. Before the wire, according to the German plan, the worm had the option of turning right. After 18464 electric shocks the worm got wise and started to turn. I vividly imagine the confrontation between the worm and the German pr

"I too, breaking out of old ways, had discovered solitude and melancholy which is at the basis of religion. Religion turns the melancholy into uplifting fear and hope. But I had rejected the ways and comforts of religion. I couldn't turn to them again, just like that. That melancholy about the world remained something I had to put up with on my own. At some times it was sharp; at some times it wasn't there."
