"if we offer too much silent assent about mysticism and superstition – even when it seems to be doing a little good – we abet a general climate in which skepticism is considered impolite, science tiresome, and rigorous thinking somehow stuffy and inappropriate. Figuring out a prudent balance takes wisdom.”

– Carl Sagan

Everyday words are inherently imprecise. They work well enough in everyday life that you don't notice. Words seem to work, just as Newtonian physics seems to. But you can always make them break if you push them far enough.

--Paul Graham, How to Do Philosophy

[surprisingly not a duplicate]

An idealist is one who, on noticing that a rose smells better than a cabbage, concludes that it will also make better soup.

-- H. L. Mencken, describing halo bias before it was named

I like the pithy description of halo bias. I don't like or agree with Mencken's non-nuanced view of idealists. it's sarcastically funny, like "a liberal is one who believes you can pick up a dog turd by the clean end", but being funny doesn't make it more true.

0Eugine_Nier10yThe point is that idealists suffer from a halo bias around their chosen ideal.
6Will_Newsome10yDo roses make for good soup? They make for good chocolate.
8Vaniver10yRose water [http://en.wikipedia.org/wiki/Rose_water] is used for flavoring, sometimes. Roses have essentially no nutritional value, though, and cabbages are widely held to taste better than they smell.
4scmbradley10yI've had rosewater flavoured ice cream. I bet cabbage ice cream does not taste as nice.

Not everything that is more difficult is more meritorious.

-Saint Thomas Aquinas

I wish I would have memorized this quote before attending university.

*This comment was inspired by Will_Newsome's attempt to find rationality quotes in Summa Theologica.

Summa Theologica is a good example of what happens when you have an excellent deductive system (Aquinas was great at syllogisms) and flawed axioms (a literal interpretation of the Bible).

6Jayson_Virissimo10yAquinas probably meant something different by "literal interpretation" than you think. For instance, I'm pretty sure he agreed with Augustine that the six days of creation were not literally six periods of 24 hours.
6Tyrrell_McAllister10yOut of curiosity, where did Augustine say that? It's interesting that anyone bothered doubting that the six days were literal before the literal interpretation became embarrassingly inconsistent with established science.
3Ezekiel10yThe first three "days" happened before the sun and moon were created, so a literal interpretation was problematic even then.
3[anonymous]10yEh, there's an easy hack around that: God already knew what the length of a day was before it created the sun and the moon.
0FiftyTwo10yThe literalness or otherwise of the description wasn't really a issue of major debate one way or the other until there was a strong alternative hypothesis. Theres no political or signalling benefit to supporting a bizarre position when you have nothing to compare it too.
1Tyrrell_McAllister10yYes. So, the question is, Which alternative hypotheses were on the table before Darwin, and why were they considered compelling?
-3Will_Newsome10yIf I was copying over rationality quotes from the Summa I'd have gone for way different stuff, Aquinas was a fucking beast of a rationalist. I was just testing LW. Karma is not nearly as useful as accurate beliefs.
3Jayson_Virissimo10yI don't know about a beast, but in general philosophers from the Middle Ages are far underrated compared to, say, philosophers from the "Enlightenment".
2FiftyTwo10yI think thats a product of people being evaluated by the 'rightness' of their conclusions rather than the validity of their arguments, so someone who rationally derived a wrong conclusion from bad data is less respected than someone who found a conclusion similar to our present ones by bad reasoning or sheer chance (e.g. certain ancient philosophers).
-2Jayson_Virissimo10yMaybe, but that doesn't explain why there is so much misinformation [https://en.wikipedia.org/wiki/Myth_of_the_Flat_Earth] about medieval philosophy [http://plato.stanford.edu/entries/medieval-philosophy/] in popular sources. For instance, as Will Newsome [http://lesswrong.com/user/Will_Newsome] tried to point out, Saint Thomas Aquinas [http://plato.stanford.edu/entries/aquinas/] was arguably a compatibilist with respect to the problem of free will [http://plato.stanford.edu/entries/freewill/], but I was taught in university that the "right" solution to the problem of free will (compatibilism [http://plato.stanford.edu/entries/compatibilism/]) had to wait for a cognitive scientist (specifically, Daniel Dennet [https://en.wikipedia.org/wiki/Daniel_Dennett]). There are numerous issues where thinkers from the Middle Ages did come to roughly the "right" answer, but that moderns teach that they didn't. There has got to be more to the story.
5Alejandro110yI am surprised by this. The proto-compatibilism of Aquinas might be little-known, but I thought it was common knowledge that compatibilism has a long pedigree before the late 20th century, including most logical positivists like Ayer and earlier British empiricists like Hume (I would include Spinoza as well). What Dennett gives is a version informed by modern cognitive science, but not especially novel in its basic features.

The road to wisdom? — Well, it's plain
and simple to express:
Err
and err
and err again
but less
and less
and less.

1Raemon10yThis has been quoted by Yvain before, but not here.
1gwern10yI was very surprised to see this was not a dupe; checking, the copy in my Mnemosyne was simply taken straight from a collection of his grooks [http://web.archive.org/web/20100124141216/http://chat.carleton.ca/~tcstewar/grooks/grooks.html] . A missed opportunity.
0Dustin10yDo you mean you have a deck for quotes? As I'm just getting into trying out spaced repetition and trying to come up with things to memorize, I'm wondering about your reasons for memorizing quotes (if that is indeed what you're doing). Do you have some sort of system of question/answer pairs that help you remember quotes that are applicable to certain situations? Or are you trying to memorize quote authors? Or what?
4gwern10yI add quotes because it's a handy sort of quotes file (many people keep them) and because I like being able to reel off quotes or just have them handy in my memory for writing. There's nothing fancy about them: the question is the quote, and the answer is all the sourcing and bibliographi information. I grade them based on whether I feel I could paraphrase them in a relevant context. ("Ah yes, good old Box's quote about how 'all models are wrong but some are useful'. Good to remember for statistical discussions. Mark that one a 4.")
0ahartell10yAre the decks you personally use available anywhere?
2gwern10yhttp://www.gwern.net/Spaced%20repetition#see-also [http://www.gwern.net/Spaced%20repetition#see-also]
0ahartell10yThanks a bunch :)

Do not accept any of my words on faith,
Believing them just because I said them.
Be like an analyst buying gold, who cuts, burns,
And critically examines his product for authenticity.
Only accept what passes the test
By proving useful and beneficial in your life.

-- The Buddha, Jnanasara-samuccaya Sutra

4Nick_Roy10yGood instrumental rationality quote; not so good for epistemic rationality.
4fortyeridania10yWhy do you say that?
4Nick_Roy10y"Proving useful in your life" (but not necessarily "proving beneficial") is the core of instrumental rationality, but what's useful is not necessarily what's true, so it's important to refrain from using that metric in epistemic rationality. Example: cognitive behavioral therapy [https://en.wikipedia.org/wiki/Cognitive_behavioral_therapy] is often useful "to solve problems concerning dysfunctional emotions", but not useful for pursuing truth. There's also mindfulness-based cognitive therapy [https://en.wikipedia.org/wiki/Mindfulness-based_cognitive_therapy] for an example more relevant to Buddhism.
5fortyeridania10yI suppose that is a tension between epistemic and instrumental rationality. Put in terms of a microeconomic trade-off: The marginal value of having correct beliefs diminishes beyond a certain threshold. Eventually, the marginal value of increasing one's epistemic accuracy dips below the marginal value that comes from retaining one's mistaken belief. At that point, an instrumentally rational agent may stop increasing accuracy. On the other hand, it may be a problem of local-versus-global optima: The marginal value of accuracy may creep up again. Or maybe those who see it as a problem can fix it with the right augmentation.
6Vladimir_Nesov10yThere is no tension. Epistemic rationality is merely instrumental, while instrumental rationality is not. They are different kinds of things [http://lesswrong.com/lw/l4/terminal_values_and_instrumental_values/]. Means to an end don't compete with what the end is.
2thomblake10yUpvoted for this
2wedrifid10yIt is useful for pursuing truth to the extent that it can correct actually false beliefs when they happen to tend in one direction.
1fortyeridania10yThis sometimes comes at the expense of other truths [http://lesswrong.com/lw/34y/does_cognitive_therapy_encourage_bias/], just as pursuing evidence for your preferred conclusion turns up real evidence but a less accurate map.
0Nisan9yRelated quote from Epictetus [http://lesswrong.com/lw/f8x/rationality_quotes_november_2012/7qhg].

“A casual stroll through the lunatic asylum shows that faith does not prove anything.”

  • Friedrich Nietzsche
0Will_Newsome10yThat would seem to be an odd notion of "faith"; is the translation untrue to the original or is Nietzsche just being typically provocative? (I also personally don't see how the quote is at all profound or interesting but that's a separate issue and more a matter of taste.)

I apologize for practicing inferior epistemic hygiene. Thank you for indirectly bringing this to my attention. I knew that the quote was commonly attributed to Nietzsche, but I had never seen the original source. It would seem to be a rephrasing of this quote from The Antichrist:

The fact that faith, under certain circumstances, may work for blessedness, but that this blessedness produced by an idée fixe by no means makes the idea itself true, and the fact that faith actually moves no mountains, but instead raises them up where there were none before: all this is made sufficiently clear by a walk through a lunatic asylum.

3Will_Newsome10yAh, that sounds a bit more like the Nietzsche I know and kinda like! Thanks for digging up the more accurate quote.
4taelor10yI'd parse the quote as meaning "Believing in something doesn't make it true", in which case it's something that pretty much everyone on this site takes for granted, but that the average person hasn't necessarily fully internalized. Yudkowsky felt the need to make a similar point near the end of this [http://yudkowsky.net/rational/bayes] article, and philosophers as diverse as St. Anselm and William James have built entire epistemologies around the notion that faith is sufficient to justify belief, so obviously it's a point that needs to be made.
2Will_Newsome10yI dunno about St. Anselm but I found James's "The Will to Believe" essay reasonable as a matter of practical rationality. The sort of Bayesian epistemology that is Eliezer's hallmark isn't exactly fundamental, and the map-territory distinction isn't either, so I don't find it too surprising that e.g. Kantian epistemology looks a lot more like modern decision theory than it does Bayesian probability theory. I suspect a lot of "faith"-like behaviors don't look nearly as insane when seen from this deeper perspective. So on one level we have day-to-day instrumental rationality where faith tends to make sense for the reasons James cites, and on a much deeper level there's uncertainty about what beliefs really are except as the parts of your utility function that are meant for cooperation with other agents (ETA: similar to Kant's categorical imperative). On top of that there are situations where you have to have something like faith, e.g. if you happen upon a Turing oracle and thus can't verify if it's telling you the truth or not but still want to do hypercomputation. Things like this make me hesitant to judge the merits of epistemological ideas like faith which I don't yet understand very well.
4fortyeridania10yThis sort of taxonomy seems to deserve a more thorough treatment in a separate post.

...when you do have a deep understanding, you have solved the problem and it is time to do something else. This makes the total time you spend in life reveling in your mastery of something quite brief. One of the main skills of research scientists of any type is knowing how to work comfortably and productively in a state of confusion.

-Anon http://www.quora.com/What-is-it-like-to-have-an-understanding-of-very-advanced-mathematics#ans873950

(emphasis mine)

Teaching, for me and several other people I know, serves the purpose of reveling in your mastery. In fact, Feynman said it best:

In any thinking process there are moments when everything is going good and you've got wonderful ideas. Teaching is an interruption, and so it's the greatest pain in the neck in the world. And then there are the longer period of time when not much is coming to you. You're not getting any ideas, and if you're doing nothing at all, it drives you nuts! You can't even say "I'm teaching my class."

If you're teaching a class, you can think about the elementary things that you know very well. These things are kind of fun and delightful. It doesn't do any harm to think them over again. Is there a better way to present them? The elementary things are easy to think about; if you can't think of a new thought, no harm done; what you thought about it before is good enough for the class. If you do think of something new, you're rather pleased that you have a new way of looking at it.

Teaching helps me a lot in this respect, because I become very insecure sometimes when I do my research.

0FeepingCreature10yI can't tell if he presents this as a good thing or a bad thing.
0FiftyTwo10yAt the very edge its also useful to be able to work while in a state of sheer existential dread.
0Eugine_Nier10yIn my experience, if you find yourself in "a state of sheer existential dread", that probably means you've done something wrong, most likely made a category error somewhere along the way.

"Never interrupt your enemy while he is making a mistake." -- Napoleon Bonaparte

(This has been mentioned before on LW but not in a quote thread. I figured it was fair game.)

7dspeyer10yJust make sure to only apply this one to your actual enemies, and not to people who generally wish you well but disagree on some key point.
5wedrifid10yInterrupting even neutral associates when they are making a mistake does not necessarily have good outcomes for you either. Being the messenger has a reputation...
0FiftyTwo10yIts apparently a misattribution sadly. [https://en.wikiquote.org/wiki/Napoleon_I_of_France#Attributed]
1Vaniver10yIt looks like it's in the attribution section to me, not the misattribution section.

...some people requested that I be prohibited from studying. One time they achieved it through a very holy and simple mother superior who believed that studying would get me in trouble with the Inquisition and ordered me not to do it. I obeyed her for the three months that she was in office in as far as I did not touch a book, but as far as absolutely not studying, this was not in my power. [...] Even the people I spoke to, and what they said to me, gave rise to thousands of reflections. What was the source of all the variety of personality and talent I found among them, since they were all one species? [...] Sometimes I would pace in front of the fireplace in one of our large dormitories and notice that, though the lines of two sides were parallel and its ceiling level, to our vision it appears as though the lines are inclined toward each other and the ceiling is lower in the distance than it is nearby. From this it can be inferred that the lines of our vision run straight, but not parallel, to form the figure of a pyramid. And I wondered if that was the reason that the ancients questioned whether the earth was a sphere or not. Because although it seemed so, their vision mig

9Kaj_Sotala10yFabius actually seems a little irrational in this quote. At first he objects to Augustus's interpretation because Augustus is not an expert on the interpretation of signs, which is reasonable. But then when Augustus does have an intepretation that's coming from an augur, Fabius still continues to question it, pitting his view against expert opinion like it was still just the opinion of Augustus. Since it is not established that Fabius would be an augur himself, this seems like motivated cognition / not properly updating on evidence. Alternatively, it could be that Fabius doesn't actually believe in omens, but in that case first appealing to the need to get an expert opinion is pretty dishonest. Of course, Alejandro's comment below does clarify that Livia is probably lying about the augur's testimony, but I'm going by the quote as it was posted (and as most people probably read/voted it).
0Thomas10yFabius does not want to argue with a fool more than it is necessary. He engages the heavy guns only when needs to, this time at the end of the dialogue. My kind of a (dishonest you say) guy.
2Will_Newsome10yBecause days is the Schelling point interpretation, and if gods are communicating with you they'll probably go for the Schelling point. Lightning implies Zeus-Jupiter, so Augustus should look into historical examples of Zeus talking to people to see if Zeus tends to be misleading in ways similar to those Fabius warns of; in fact the augur had probably already considered things like this before speaking with Livia. And Fabius should trust the augur, who is a specialist in the interpretation of signs and probably has more details of the case than he does. I mean seriously, what are the chances that the letter C would get struck by lightning? We are beyond the point of arbitrary skepticism. Deny the data or trust the professionals. (I'm not familiar with the series in question, I'm just filling in details in the most likely way I can think of.) ETA: Wait, maybe Fabius is trolling Augustus/me? ...Nice one Fabius! I approve of your trolling. Downvote retracted. (Oh yeah and this is an excuse to link to the Wiki article on assassination markets [http://en.wikipedia.org/wiki/Assassination_market].)
2Alejandro110yFor everyone who knows that Livia is the Magnificent Bastard of the series (which is made clear from the first episode, so no spoiler there), the highest probability mass goes to the hypothesis that was lying about having spoken to an augur or about what he told her, and that she wanted Augustus to question her and only feigned to resist. And "everyone who knows" at this stage probably includes Fabius, and every other character but Augustus.
0Will_Newsome10ySo the leader of the relevant transhumanly intelligent entities is on the side of the Magnificent Bastard? If I was Augustus I'd seriously consider being nice to the Jews and asking YHWH for guidance. (Rationality: it works even better in magical universes! (Like, ahem, the one we're in.))

Chu-p’ing Man studied the art of killing dragons under Crippled Yi. It cost him all the thousand pieces of gold he had in his house, and after three years he'd mastered the art, but there was no one who could use his services. - Chuang Tzu

So he decided to teach others the art of kiling dragons. - René Thom

In questions of this appalling magnitude, I find the best way to "overcome bias" is often to find perspectives which seem to make each answer obvious. Once we recognize that both A and B are obviously true, and A is inconsistent with B, we are in the right mindset for actual thought.

--Mencius Moldbug

2gwern10yRemember sources please; "How Dawkins got pwned (part 7)" [http://unqualified-reservations.blogspot.com/2007/11/how-dawkins-got-pwned-part-7.html] , 8 November 2007
0GLaDOS10yYou have a thing for Moldbug too, don't you? ^_^
1Manfred10yThis sounds like bad advice. In Moldbug's application of it, for example, making things "obvious" corresponds to making bad arguments - arguments that, in some alternate reality, possibly made of straw, would correspond to some possibly straw person who found the argument very obvious. And then you say "well, obvious argument #1 is awful, so by process of elimination let's go with obvious argument #2! Q.E.D."

Human knowledge and human power meet in one; for where the cause is not known the effect cannot be produced. Nature to be commanded must be obeyed; and that which in contemplation is as the cause is in operation as the rule.

Francis Bacon

0fortyeridania10yWow, I'm surprised this had not been posted before. Good catch.
1NancyLebovitz10yI was very surprised, too. I'd found a similar quote-- one that that I'll put in a top-level comment-- and checked for the Bacon quote.

"Don't ask whether predictions are made, ask whether predictions are implied."

--Steven Kaas

"Is it hard?"

"Not if you have the right attitudes. It’s having the right attitudes that’s hard."

-- Robert M. Pirsig, Zen and the Art of Motorcycle Maintenance

Use only that which works, and take it from any place you can find it.

--Bruce Lee

8MixedNuts10yThat seems rather applause-lighty. The reversal is abnormal; who would say "Use some things that don't work"? Maybe in some traditionalist cultures "Resist the appeal of using things that work but come from unworthy places" would sound wise, but on LessWrong it would likely get stares.

Bruce Lee was a martial artist, and martial arts is a field where a lot of people go by tradition rather than checking on what works.

2[anonymous]10yawesomely relevant video:Joe Rogan on MMA and Kung Fu [http://www.youtube.com/watch?v=I9wEQ5RJD8w&feature=related]

That seems rather applause-lighty.

I think many cited quotations sound applause-lighty. They are meant to by pithy encapsulations of LW themes, after all. And I don't think that's necessarily a problem; applause lights are a problem for things that might be taken as reasoning, like posts.

2Desrtopa10y"Use only that which works" is obvious enough to be unhelpful, but "take it from any place you can find it" was pretty novel in the context in which he proposed it, and still is to a lot of people in a lot of domains. The existence of the Traditional branch of Jeet Kune Do (as opposed to the Concepts branch,) which exclusively teaches the martial art as Bruce Lee practiced it at the time of his death, is testament to the strength of humans' tendency to behave counter to this advice.

... if anyone thinks they can get an accurate picture of anyplace on the planet by reading news reports, they're sadly mistaken.

--Bruce Schneier

It’s not a good idea for members of the faith-based community like Hitchens to proclaim things like: Science proves we’re all genetically equal, so therefore you shouldn’t be beastly toward people of other races. The obvious flaw in this strategy is that eventually people will figure out that you are lying about what the science of genetics says, and therefore, by your own logic, that discredits the perfectly valid second half of your assertion.

--Steve Sailer

4Booty4Bayes10yGood chop, bro.

In short, they made unrealistic demands on reality and reality did not oblige them.

Cory Doctorow talking about DRM, but I think there are some wider applications.

3gwern10yReminiscent of one of my favorite Bruce Schneier quotes [https://plus.google.com/103530621949492999968/posts/FcqRJPRCYZ7].

Imagine willpower doesn't exist. That's step 1 to a better future.

"This has been a good day... I haven't done a single thing that was stupid..."

"Have you done anything that was smart?"

--Peanuts (Nov. 23, 1981) by Charles Schulz

Most people are theists not because they were "reasoned into" believing in God, but because they applied Occam's razor at too early an age. Their simplest explanation for the reason that their parents, not to mention everyone else in the world, believed in God, was that God actually existed. The same could be said for, say, Australia.

8gwern10yPlease remember sources; this is from "How I Stopped Believing in Democracy" [http://unqualified-reservations.blogspot.com/2008/01/how-i-stopped-believing-in-democracy.html] , 31 January 2008.
7CaveJohnson10yIs it conventional to add sources when it is an on-line? Sorry didn't know that was expected, since it wasn't in the posting rule set. Will remember to add sources in the future. BTW gwern sometimes your attention to detail is as unnerving as it is helpful and impressive.
0gwern10yI thought it was, but then, I may be interested only because it makes it easier in the future to track down citations if there is a title and URL (and because if I click on a URL, it goes into my archive bot [http://www.gwern.net/Archiving%20URLs]). It's just time-wasting... Heck, I time-waste on my time-wasting, I'm supposed to be adding citations on how people are biased against spaced repetition even when their scores are better with SR to my respective article.

"The last enemy that shall be destroyed is death"

--1 Corinthians 15:26

(I wonder what Eliezer would've made of it - as far as I know, he never read Deathly Hallows and so never read about the tombstone.)

8Raemon10yWell, he knows about the Hallows themselves via wiki-readings. I think he would have written the story the way it is whether he knew about the tombstone or not, but I put fairly high probability that he does know about the tombstone and how fantastically awesome an endcap it's going to be on the story.
1gwern10yMm. Maybe: http://predictionbook.com/predictions/5122 [http://predictionbook.com/predictions/5122]
6Raemon10yI think there's a close to 100% chance that the tombstone will be alluded to, because even if Eliezer DIDN'T know about it before, he will by the time the story ends (because I will have questioned and informed him about this), and after that I just can't imagine him making such a terrible mistake as to NOT include the tombstone's quote. I do think a simple bet of "did he already plan this?" is feasible. We can just ask him. (I put odds at 75%). (By "close to 100%" I mean maybe 95. I can think of scenarios where he hadn't originally planned for the tombstone and where it would be hard to integrate it)
2gwern10yOh fine: http://predictionbook.com/predictions/5124 [http://predictionbook.com/predictions/5124] But you'd better ask him now!
4Eliezer Yudkowsky10yI was already aware of the quote. It's on James and Lily's tombstone (in canon).
3gwern10yI see; but the predictions/questions wasn't were you aware of it at all, but were you planning to incorporate it [http://predictionbook.com/predictions/5124] ex ante, and did you [http://predictionbook.com/predictions/5122] ex post.
7Eliezer Yudkowsky10yIf it's incorporated it will have been planned beforehand.
2gwern10yYou and your silly hatred of spoilers. (The recent experimental evidence [http://psy2.ucsd.edu/~nchristenfeld/Publications_files/Spoilers.pdf], BTW, suggests spoilers are not harmful but helpful for enjoyment.) But I guess that statement works.
5NancyLebovitz10yFor what it's worth, there are stories where I've appreciated going in with no knowledge except for some reason to think I'd like it (the movie Hugo 3D is a recent example, for Mieville's Un Lun Dun I just had a reasonable guess about genre). I think I lost some of the impact of A Deepness in the Sky because I knew what Focus was before I started reading.
0[anonymous]10yI think whether spoilers are harmful varies among works and among readers. (For example, ‘finding out how it ends’ was the only reason why I finished reading Digital Fortress by Dan Brown rather than throwing it in the garbage bin right after the first couple chapters; if I had already known the ending I would likely not have enjoyed it at all (except possibly for laughing at it).)

I think whether spoilers are harmful varies among works and among readers. (For example, ‘finding out how it ends’ was the only reason why I finished reading Digital Fortress by Dan Brown rather than throwing it in the garbage bin right after the first couple chapters;

This is an example of when spoilers are good, right? Every person saved from reading Dan Brown...

5TheOtherDave10yI'm confused by what this is an example of. Had you known how it ended, would you have finished reading the book? If so, why? If not, how would that have been harmful?
0[anonymous]10y1) Probably not; 2) that would have taken away from me the enjoyment of reading the book to find out the ending. (I was quite bored that day, and I didn't have my computer or my music player or anything else to do with me.)
1TheOtherDave10y(nods) OK, sure... if the most enjoyable thing I can do right now is read a book that isn't enjoyable to read, in order to get the enjoyment of reading the book and being surprised by its ending, then telling me the ending is harmful. Agreed. I have trouble imagining actually being in that state personally, but of course people vary.
1MixedNuts10yThe existence of bookshops in train stations and airports selling badly-written suspense novels suggests this is a common state.
0TheOtherDave10yWell, I too have bought a number of books in airports and train stations over the years, and I don't see how the fact that airports and train stations sell the books they sell provides evidence to choose between the theory that army1987's state is common, and the theory that my state is common. (Of course, the reality could also be both, or neither.)
0Raemon10yIf I had been thinking better I would have specified "did he know" rather than "did he plan" so that we could resolve the issue. (I think there is at least a 30% chance one (if not both) of us will have forgotten this wager by the time the reveal happens)
0gwern10yThat's what PredictionBook is for. So far I have a good record for long-term use of it...

“The general method that Wittgenstein does suggest is that of ’shewing that a man has supplied no meaning for certain signs in his sentences’.

I can illustrate the method from Wittgenstein’s later way of discussing problems. He once greeted me with the question: ‘Why do people say that it was natural to think that the sun went round the earth rather than that the earth turned on its axis? I replied: ‘I suppose, because it looked as if the sun went round the earth.’ ‘Well,’ he asked, ‘what would it have looked like if it had looked as if the earth turned on its axis?’

This question brought it out that I had hitherto given no relevant meaning to ‘it looks as if’ in ‘it looks as if the sun goes round the earth’.

My reply was to hold out my hands with the palms upward, and raise them from my knees in a circular sweep, at the same time leaning backwards and assuming a dizzy expression. ‘Exactly!’ he said.”

–Elizabeth Anscombe, [An Introduction To Wittgenstein’s Tractatus](http://www.archive.org/details/introductiontowi009827mbp) (1959); apropos of a recent Scot Sumner blog post

Another great quote by Sumner in that same post:

The Great Depression was originally thought to be due to the inherent instability of capitalism. Later Friedman and Schwartz blamed it on a big drop in M2. Their view is now more popular, because it has more appealing policy implications. It’s a lot easier to prevent M2 from falling, than to repair the inherent instability of capitalism. Where there are simple policy implications, a failure to do those policies eventually becomes seen as the “cause” of the problem, even if at a deeper philosophical level “cause” is one of those slippery terms that can never be pinned down.

Science isn't just a job, it's a means of determining truth. Methods of determining truth that aren't trustworthy in the laboratory don't become trustworthy when you leave it. There is no doctrine of applying scientific methodology to every aspect of one's life, you either follow trustworthy methods of investigation or you don't, and "follow trustworthy methods of investigation" is the core of science.

~Desertopa, TVTropes Forum

There are types of valid evidence that aren't scientific. In particular science is also partially a social process, whereas you trying to find the truth for yourself is not.

A critical analysis of the present global constellation -- one which offers no clear solution, no "practical" advice on what to do, and provides no light at the end of the tunnel, since one is well aware that this light might belong to a train crashing towards us -- usually meets with reproach: "Do you mean we should do nothing? Just sit and wait?" One should gather the courage to answer: "YES, precisely that!" There are situations when the only truly "practical" thing to do is to resist the temptation to engage immediately and to "wait and see" by means of a patient, critical analysis.

Slavoj Žižek, Violence, emphasis added. Admittedly not the most clear elucidation of the subject of how urgency (fabricated or otherwise) should affect ethical deliberation, but see also his essay "Jack Bauer and the Ethics of Urgency" -- if you're into that sort of thing.

The ultimate theological question is: ‘Where does the Sun go at night?’.

The answer that so many civilisations agreed for so long was: ‘The Sun is driven by one of the gods, and at night it goes under the Earth to fight a battle. There is at least some risk that the god will lose this battle, and so the Sun may not rise tomorrow’. It’s something the human race understood was a cast iron fact before they knew how to cast iron. It survived as the working model twenty-five times longer than the four hundred years we’ve understood the Earth goes around the Sun.

Lance Parkin, Above us only sky

This is less a rationality quote than a "yay science" quote, but I find that impressive beyond words. For millenia that was a huge and frightening question, and then we went and answered it, and now it's too trivial to point out. We found out where the sun goes at night. I want to carve a primer on cosmology in gold letters on a mountain, entitled something in all caps along the lines of "HERE IS THE GLORY OF HUMANKIND".

It survived as the working model twenty-five times longer than the four hundred years we’ve understood the Earth goes around the Sun.

Is it excessive nitpicking to point out that the daily disappearance and reappearance of the Sun has to do with the Earth's rotation on its axis, not its rotation about the Sun? (Probably not, as the first comment on Parkin's blog posting points out the same.)

The truth is common property. You can't distinguish your group by doing things that are rational, and believing things that are true.

Paul Graham, Lies We Tell Kids

The truth is common property. You can't distinguish your group by doing things that are rational, and believing things that are true.

It would seem that if no other humans are behaving rationality and your group is behaving rationally then even Sesame St could tell you which of these things is not the same.

7roystgnr10yIf no other groups of humans are behaving as rationally as yours is, then it's likely no other humans are capable of easily identifying that your group is the one with the high level of uniquely rational behavior. To the extent that other groups can identify rational behaviors of yours, they will have already adopted them and will not consider you unique for having adopted them too. You can signal the uniqueness your group by believing and doing things that are both rational and unpopular, but to most outsiders this only signals uniqueness, not rationality, because the reason such things are unpopular is because most people don't find them to be obviously rational. And the outsiders are usually right: even though they're wrong in your particular actually-is-rational case, that's outnumbered by the other cases which, from the outside, all appear to be similar arational group-identifying behaviors and rationalizations thereof. E.g. at first glance there's not a huge difference between "I'm going to get frozen after I die", "I don't eat pork", "I avoid caffeine and hot drinks", etc.
3wedrifid10yNot actually true. I'd like it to be!
0TheOtherDave10yDamn skippy. I'd even settle for the above being true of my group with respect to other groups.
1Eugine_Nier10yDepends on how immediate and/or dramatic the benefits of the rational behavior are.
1Will_Newsome10ythen you're probably insanely wrong.
1wedrifid10yWhy do you say that? That doesn't sound true. Humans are monkeys - I should be surprised if a group of monkeys acts perfectly rational. I suggest that any insanity that however insane I may be this issue is straightforward.
0Will_Newsome10yMy original comment was meant to be a mildly elaborate adianoeta that is more than the sum of its parts (except that the addition of "insanely" was a regrettable and meaningless rhetorical flourish). So if I seem straightforwardly wrong then maybe something was lost in interpretation or I just didn't do it right.

3satt10yIt's been a while since I read that essay. I can't tell whether that quotation's meant to be an example of a lie we tell kids, or one of Paul Graham's own beliefs! (An invertible fact [http://lesswrong.com/lw/2u3/request_interesting_invertible_facts/]?)
2fortyeridania10yIt is Graham's own belief.
0satt10yYes, a look at it in context in the essay confirms that — but isn't it a strange belief for someone like Paul Graham to have? It looks false to me (although "truth is common property" is ambiguous). I think a group could make itself very distinct by believing certain truths and doing certain rationally justified things.
1fortyeridania10yI don't know whether it's strange for Graham to think this; I haven't read much of his stuff. I found the phrase "common property" odd too. I associate the phrase with "commons," as in tragedy [http://www.sciencemag.org/content/162/3859/1243.full] of the [http://en.wikipedia.org/wiki/Tragedy_of_the_commons] commons [http://www.econlib.org/library/Enc/TragedyoftheCommons.html].

0soreff10yMost groups of weapon developers probably hope to keep their knowledge distinct from that of other groups for as long as they can...
0fortyeridania10yWhat? I don't get this. Also, why should weapons developers care whether their products are distinctive? Having better weapons helps, and being better is being distinctive, but so is being worse.
1soreff10yI apologize. I should have been clearer. I mean that if a group of weapons developers, such as, for instance, the Manhattan Project, discovers certain critical technical data necessary to their weapons, such as, for instance, the critical mass of Pu-239, they will often prefer that these truths not spread to other groups. For as long as they are able to keep this knowledge secret, it is indeed a set of truths that makes this set of weapons designers distinct from other groups.
0fortyeridania10yOh, I see now. Thanks for clarifying. But if other developers are incorrect, then you'd want to be correct; and if other developers are correct, you'd still want to be correct. Put game-theoretically, accuracy strictly dominates inaccuracy. By contrast, isnt' distinctiveness only good when it doesn't compromise accuracy?

Prompted by Maniakes', but sufficiently different to post separately:

It cannot have escaped philosophers' attention that our fellow academics in other fields--especially in the sciences--often have difficulty suppressing their incredulous amusement when such topics as Twin Earth, Swampman, and Blockheads are posed for apparently serious consideration. Are the scientists just being philistines, betraying their tin ears for the subtleties of philosophical investigation, or have the philosophers who indulge in these exercises lost their grip on reality?

These bizarre examples all attempt to prove one "conceptual" point or another by deliberately reducing something underappreciated to zero, so that What Really Counts can shine through. Blockheads hold peripheral behavior constant and reduce internal structural details (and--what comes to the same thing--intervening internal processes) close to zero, and provoke the intuition that then there would be no mind there; internal structure Really Counts. Manthra is more or less the mirror-image; it keeps internal processes constant and reduces control of peripheral behavior to zero, showing, presumably, that external behavior Reall

8cousin_it10yI don't understand that quote. A good Bayesian should still pick the aposteriori most probable explanation for an improbable event, even if that explanation has very low prior probability before the event.
8Eugine_Nier10yI suspect the point is that it's not worthwhile to look for potential explanations for improbable events until they actually happen.
5APMason10yI think it's more than that - he's saying that if you have a plausible explanation for an event, the event itself is plausible, explanations being models of the world. It's a warning against setting up excuses for why your model fails to predict the future in advance - you shouldn't expect your model to fail, so when it does you don't say, "Oh, here's how this extremely surprising event fits my model anyway." Instead, you say "damn, looks like I was wrong."

"A Confucian has stolen my hairbrush! Down with Confucianism!"

-GK Chesterton (on ad hominems)

As in the Roman empire age, the theoretical concepts, taken out of the theories assigning their meaning and considered instead real objects, whose existence can be apparent only to the initiated people, are used to amaze the public. In physics courses the student (now unaware of the experimental basis of heliocentrism or of atomic theory, accepted on the sole basis of the authority principle) gets addicted to a complex and mysterious mythology, with orbitals undergoing hybridization, elusive quarks, voracious and disquieting black holes and a creating Big Bang: objects introduced, all of them, in theories totally unknown to him and having no understandable relation with any phenomenon he may have access to.

Lucio Russo, The Forgotten Revolution: How Science Was Born in 300 BC and Why it Had to Be Reborn

It's true that the author reads Hellenic scientists in the most favorable possible light while reading Renaissance scientists in the least favorable possible light. But he gives extensive quotations from the available sources, so that you can judge for yourself whether his interpretations are stretched.

"A “lie-to-children” is a statement which is false, but which nevertheless leads the child’s mind towards a more accurate explanation, one that the child will only be able to appreciate if it has been primed with the lie." "Yes, you needed to understand that” they are told, “so that now we can tell you why it isn’t exactly true." It is for the best possible reasons, but it is still a lie".”

Accepting this tension is the mark of an educated man, as Aristotle says.

We made our oath to Vavilov
We'd not betray the solanum
The acres of asteraceae
To our own pangs of starvation

"When The War Came", by The Decemberists

(from memory, will fix any errors later)

http://en.wikipedia.org/wiki/Nikolai_Vavilov

"While developing his theory on the centres of origin of cultivated plants, Vavilov organized a series of botanical-agronomic expeditions, collected seeds from every corner of the globe, and created in Leningrad the world's largest collection of plant seeds. This seedbank was diligently preserved even throughout the 28-month Siege of Leningrad, despite starvation; one of Nikolai's assistants starved to death surrounded by edible seeds."

2Will_Newsome10yThank you kind sir.
6fortyeridania10yCan you elucidate the connection to rationality?

A few Google searches resolved this question for me, and proved very interesting besides. Vavilov was a Soviet botanist focused on the cultivation of efficient seeds to mitigate hunger. In World War Two, Vavilov's Leningrad seedbank came under siege by the Nazis, who apparently wanted to steal/destroy the seeds. Considering the supplies vital to Russia's long-term survival, several of the scientists swore oaths to protect the seedbank against German forces, starving foragers, and rats.

They succeeded in doing so. The scientist-guards were so loyal that many of them died of starvation despite being in a facility full of edible seeds, as well as potatoes, corn, rice, and wheat. The seedbank endured the siege and was replenished after the city was liberated.

Vavilov himself did not live to see the victory of his researchers, as he had been sent to a camp thanks to his disapproval of the scientific fraud of Lysenkoism and died (ironically, of malnutrition) before the war ended.

I replied as follows: "What would you think of someone who said, "I would like to have a cat, provided it barked"? [...] As a natural scientist, you recognize that you cannot assign characteristics at will to chemical and biological entities, cannot demand that cats bark or water burn. Why do you suppose that the situation is different in the "social sciences?"

-- Milton Friedman

2gwern10yOne of these things is not like the others, one of these things does not belong.

There are valid quibbles and exceptions on both counts. Some breeds of cats make vocalizations that can reasonably be described as "barking", and water will burn if there are sufficient concentrations of either an oxidizer much stronger than oxygen (such as chlorine triflouride) or a reducing agent much stronger than hydrogen (such as elemental sodium).

In the general case, though, water will not burn under normal circumstances, and most cats are physiologically incapable of barking.

The point of the quote is that objects and systems do have innate qualities that shape and limit their behaviour, and that this effect is present in social systems studied by economists as well as in physical systems studied by chemists and biologists. In the original context (which I elided because politics is the mind killer, and because any particular application of the principle is subject to empirical debate as to its validity), Friedman was following up on an article about how political economy considerations incline regulatory agencies towards socially suboptimal decisions, addressing responses that assumed that the political economy pressures could easily be designed away by revising the agencies' structures.

1gwern10yI was actually thinking in terms of 'cats can deliberately meow in an annoying fashion [http://www.scientificamerican.com/blog/post.cfm?id=the-manipulative-meow-cats-learn-to-2009-07-13] (abstract [http://www.cell.com/current-biology/abstract/S0960-9822%2809%2901168-3]) like human infants and this behaviors seems perfectly modifiable, so a transhumanist could have a decent reason for preferring cats to bark than meow; and this is really stupid anyway, since we can change cats easily - we certainly can demand cats bark - but we can't change physis easily and can't demand water burn'.
3Manfred10ypfsch. You can burn water if you add salt and radio waves. Or if you put it in an atmosphere containing a reactive fluorine compound. Etc etc etc.
0Document10yThat since their preference harms nobody (apart from unadopted cats) and the utility function is not up for grabs [http://wiki.lesswrong.com/wiki/The_utility_function_is_not_up_for_grabs], I have no grounds to criticize them?
4Maniakes10yThe preference alone is mostly harmless. When the preference is combined with the misapprehension that the preference can be fulfilled, it may harm the person asserting the preference if it leads them to make a bad choice between a meowing cat, a barking dog, or delaying the purchase of a pet. If the preference order were (1. Barking Cat, 2. Barking Dog, 3. Meowing Cat, 4. No Pet), then the belief that a cat could be taught to bark could lead to the purchase/adoption of a meowing cat instead of the (preferred) barking dog. Likewise, in the above preference order, or with 2 and 3 reversed, the belief in barking cats could also lead to the person delaying the selection of a pet due to the hope that a continued search would turn up a barking cat. The problem is magnified, and more failure modes added, when we consider cases of group decision-making.
0dlthomas10y"I would like to have a cat, provided it barked" states that U(barking cat) > U(no cat) > U(nonbarking* cat). Preferring a meowing cat to no cat is a contradiction of what was stated. The issue you raise can still be seen with U(barking cat) > U(barking dog) > U(no pet) > U(nonbarking cat), however - a belief in the attainability of the barking cat may cause someone to delay the purchase of a barking dog that would make them happier. *In common usage, I expect that we should restrict it from "any nonbarking cat" to "ordinary cat", based on totally subjective intuitions. I would not be surprised by someone who said "I would like an X, provided it Y" for a seemingly unattainable Y, and would not have considered whether they would want an X that Z for some other seemingly unattainable Z. I think they just would have compared the unusual specimen to the typical specimen and concluded they want the former and don't want the latter. This is mostly immaterial here, I think.
1Maniakes10yI stand corrected.
0Document10yThat's strictly ruled out by the wording in the quote. While people often miscommunicate their preferences, I don't see particular evidence of it there, or even that the hypothetical person is under a misapprehension. To take it back to metaphor: the flip side of wishful thinking is the sour grapes fallacy, and while the quote doesn't explicitly commit it, without context it's close enough to put me moderately on guard.
1Maniakes10yHere is the full article from which the quote was taken: http://www.johnlatour.com/barking_cats.htm [http://www.johnlatour.com/barking_cats.htm]

2atorm10yWhat about people who want to reject the claims of religion but still want warm fuzzies? Maybe atheism wouldn't get such a bad rap in the public eye if it felt more welcoming for people who want truths but also want the sense of community provided by religion.
1faul_sname10yPaganism? It seems like one of the more accepting groups, and you don't need to actually believe to celebrate/be in a community.
0atorm10yInteresting idea, but identifying as pagan will probably raise as many eyebrows as atheism, if not more.

Most people you know are probably weak skeptics, and I would probably fit this definition in several ways. "Strong skeptics" are the people who write The Skeptics' Encyclopedia, join the California Skeptics' League, buy the Complete Works of James Randi, and introduce themselves at parties saying "Hi, I'm Ted, and I'm a skeptic!". Of weak skeptics I approve entirely. But strong skeptics confused me for a long while. You don't believe something exists. That seems like a pretty good reason not to be too concerned with it.

The next sentence is

It's not like belief in UFOs killed your pet hamster when you were a kid or something and you've had a terrible hatred of it ever since.

Skeptics will tell you that yes, it did. Belief that the Sun needs human sacrifices to rise in the morning killed their beloved big brother, and they've had a terrible hatred of it ever since. And they must slay all of its allies, everything that keeps people from noticing that Newton's laws have murder-free sunrise covered.

More accurately, Yvain-2004

8fortyeridania10yIs it more accurate to put it thus because Yvain-2012 disagrees with Yvain-2004 on this issue?

I don't know if there's enough of a specific, meaningful claim there for me to disagree with, but Yvain-2012 probably would not have written those same words. Yvain-2012 would probably say he sometimes feels creeped out by the levels of signaling that go on in the skeptical community and thinks they sometimes snowball into the ridiculous, but that the result is prosocial and they are still performing a service.

(really I can only speak for Yvain-2011 at this point; my acquaintance with Yvain-2012 has been extremely brief)

-20Will_Newsome10y
9Stabilizer10yWell, even if Yvain-2012 does not disagree with Yvain-2004, it would be nice to have the year attached. I would like that the year-attachment convention for attributing quotes and ideas becomes more widespread. Right now, the default assumption that everybody makes is that people are consistent over time. In reality, people almost surely change over time, and it is unreasonable to expect them to justify something which their earlier selves said. So, it would be really nice if the default was year-attachment.
0fortyeridania10yThat would seem to have benefits relative to no further information (except the author's name), but would the benefits be greater than those afforded by the current convention of citing the relevant work? Or maybe you think people don't follow that convention enough and they would be more likely to cite something if the thing they had to cite was just a date?
0Stabilizer10yCiting the original work would be the best I suppose. But in relatively informal contexts, like internet forums, it is probably easier for the reader to quickly have a sense of when the given quote was said if the year is attached.
4zntneo10yI would say that for instance I don't believe that most alt med stuff works but this is exactly the reason I care that others know this and how we know this. This attitude infuriates me.
6machrider10yThe fact is that there are many battles worth fighting, and strong skeptics are fighting one (or perhaps a few) of them. (As I was disgusted to see recently, human sacrifice [http://news.yahoo.com/child-sacrificed-liver-offered-gods-indian-police-074513654.html] apparently still happens.) However, I also think it's ok to say that battle is not the one that interests you. You don't have the capacity to be a champion for all possible good causes, so it's good that there is diversity of interest among people trying to improve the human condition.
3zntneo10yI totally agree if its not your cup of tea fine. What pisses me off is the line about " if you don't believe it exists it seems like a good reason to not be concerned with it"
2fortyeridania10yThe previous quotation [http://lesswrong.com/lw/94r/rationality_quotes_january_2012/5ktl] would seem to speak in favor of more strong skeptics.

Being right in the sense of being correct is not sufficient to win. Political technology determines political success. Learn how to organize and how to communicate. Most political technology is philosophically neutral. You owe it to your philosophy to study how to win.

Morton Blackwell

4Nornagest10yI might have upvoted the first sentence of this -- it's accurate, at least, if a little unproductive -- but out of context the rest is difficult to parse and might imply some seriously problematic attitudes. I take it political technology means something along the lines of "rhetoric"?
-2[anonymous]10ySure, it probably does, on the part of Blackwell. He is something of a fairly mindless conservative, not much of a libertarian, and he supports central bankers. But this part of his philosophy is worthy. He believes that if you're in a fight for your life, you should fight hard. ...Similar to Penn Jillette's advocacy of evangelism, even evangelism that he personally disagrees with. If the stakes are high, then even those on the wrong side of the stakes should value their position enough to fight for it, or change their opinion. Not necessarily so. Rhetoric is far from the only means of shifting a vote. It is one tool, there are many, many others. In fact, almost any vote can be shifted, given enough effort. Enough effort can be directed at nonvoters to mobilize them, etc... So, if you're trying to do something important (such as end slavery, release the victimless crime offenders from prison, etc...) you should learn how to win elections, since that's easier than engaging in violence commensurate with the level of importance attached to the issue. At some point, vital issues of life or death decay to violence (Civil War), if there is no political solution forthcoming. ---The victimized eventually refuse to stay victimized, or worse, the victimizers refuse to settle with too little victimization.

3MarkusRamikin10yHow are those things "convention"? Did all sentience have a pow-wow some time back and decide to experience such and such sensations when confronted with such and such physical things?
7Nornagest10yI read it as saying they're conventional in the sense that the lines between categories of sensory experience are drawn by consensus, lacking direct access to the experiences of others. We of course lack direct access to the atomic-scale world as well, but I imagine that's the point -- atomism was a lot more abstract to the likes of Democritus than atomic theory is to us. The underlying physical reality is in a certain sense abstracted away from us, and we reflect that by talking about physical experiences in a conventional way, but those experiences are still rooted in the reality of atoms and space -- or distributions of probability density, if you prefer.

What interest, zest, or excitement can there be in achieving the right way, unless we are enabled to feel that the wrong way is also a possible and a natural way, — nay, more, a menacing and an imminent way?

Lack of experience diminishes our power of taking a comprehensive view of the admitted facts. Hence those who dwell in intimate association with nature and its phenomena grow more and more able to formulate, as the foundations of their theories, principles such as to admit of a wide and coherent development: while those whom devotion to abstract discussions has rendered unobservant of the facts are too ready to dogmatize on the basis of a few observations.

3MixedNuts10yRecomputing everything/random things/currently unsatisfying things is expensive and error-prone. The standard for new good ideas may be to look at other cultures.

I note, however, that one should look at subcultures for ideas as well, not just at the mainstream cultures of different geographical regions.

Nominal essences are all the essences that science needs, and some are better than others, because they capture more regularity in nature.

"People are stupid; given proper motivation, almost anyone will believe almost anything. Because people are stupid, they will believe a lie because they want to believe it's true, or because they are afraid it might be true. People's heads are full of knowledge, facts, and beliefs, and most of it is false, yet they think it all true.

4Manfred10yGeneralization'd.
0scmbradley10ySorry I'm new. I don't understand. What do you mean?
2Manfred10yUm, so the " 'd " suggests that something has been affected by a noun [http://2.bp.blogspot.com/_CSmsEIWZS8g/SzP2zQHf_2I/AAAAAAAACvE/iJDlnG7sWbQ/s400/TGS+MSG'D.jpg] . In this case, the statement "every disputant is partly right and partly wrong" is affected by generalization. In that it is, er, a false generalization.
0scmbradley10yWhat do you mean "the statement is affected by a generalisation"? What does it mean for something to be "affected by a generalisation"? What does it mean for a statement to be "affected"? The claim is a general one. Are general claims always false? I highly doubt that. That said, this generalisation might be false, but it seems like establishing that would require more than just pointing out that the claim is general.
0Manfred10yRight. So calling it a "false generalization" needed two words. Anyhow: Where does the sun go at night? How big is the earth? Is it harmful to market cigarettes to teenagers? Is Fermat's last theorem true? Can you square the circle? Will heathens burn in hell for all eternity?
0scmbradley10yEr. What? You can call it a false generalisation all you like, that isn't in itself enough to convince me it is false. (It may well be false, that's not what's at stake here). You seem to be suggesting that merely by calling it a generalisation is enough to impugn its status. And in homage to your unconvential arguing style, here are some non sequituurs: How many angels can dance on the head of a pin? Did Thomas Aquinas prefer red wine or white wine? Was Stalin lefthanded? What colour were Sherlock Holmes' eyes?
1Manfred10ySuppose that I wanted to demonstrate conclusively that a generalization was false. I would have to provide one or more counterexamples. What sort of thing would be a counterexample to the claim "each party to all disputes that persist through long periods of time is partly right and partly wrong?" Well, it would have to be a dispute that persisted through long periods of time, but in which there was a party that was not partly right and partly wrong. So in my above reply, I listed some disputes that persisted for long periods of time, but in which there was (or is) a party that was not partly right and partly wrong.
0scmbradley10yAh I see now. Glad we cleared that up. Still, I think there's something to the idea that if there is a genuine debate [http://en.wikipedia.org/wiki/No_true_Scotsman] about some claim that lasts a long time, then there might well be some truth on either side. So perhaps Russell was wrong to universally quantify over "debates" (as your counterexamples might show), but I think there is something to the claim.
