Here's the new thread for posting quotes, with the usual rules:
And here, according to Trout, was the reason human beings could not reject ideas because they were bad: Ideas on Earth were badges of friendship or enmity. Their content did not matter. Friends agreed with friends, in order to express friendliness. Enemies disagreed with enemies, in order to express enmity. The ideas Earthlings held didn’t matter for hundreds of thousands of years, since they couldn’t do much about them anyway. Ideas might as well be badges as anything.

Doctor Slithingly watched the readout on the computer screen and rubbed his hands together. ‘Excellent,’ he muttered, his voice a thin, rasping hiss. ‘Excellent!’ He laughed to himself in a chilling falsetto. ‘Soon my plan will come to fruition. Soon I will destroy them all!’ The room resounded with the sound of his insane giggling. This was the culmination of years of research – years of testing tissue samples and creating unnatural biological hybrids – but now it was over. Now, finally, he would destroy them all – every single type and variation of leukaemia. In doing so, he would render useless the work of thousands of charitable organisations as well as denying medical professionals the world over a source of income. He would prevent the publication of hundreds of inspiring stories of survival and sacrifice which might otherwise have sold millions of copies worldwide. ‘Bwahaha!’ he laughed. ‘So long, you meddling haematological neoplasm, you!’

You are not the king of your brain. You are the creepy guy standing next to the king going "a most judicious choice, sire".
-- Steven Kaas
Steven and most of the people here (including me) do indeed believe that "you are your brain" in the sense that the mind is something that the brain does. But Steven's epigram is using "you" in a narrower sense, referring to just the conscious, internal-monologue part of the mind.
In the fable of the fox and the grapes, it's the fox's brain that is the proximate cause of him giving up the attempt to get the grapes, but it's the "creepy vizier" part of his mind that makes up the "I didn't want them anyway" story.
(Edit: I should have said "most of the other people here" in my first sentence. In case you didn't know it, Steven Kaas is an LWer. He is kind enough to let me and others earn tons of karma by quoting his Twitter bons mots.)
It's illustrating the thing from psychology where your conscious self (the "you" in "you are" here) often seems to be more about making up narratives about why you do things you somewhat unconsciously decide to do, rather than fully consciously deciding to do what you do.
It's not terribly obvious normally, but scary stuff happens when you get a suitable type of brain damage. Instead of necessarily going "hm, my introspective faculties seem to be damaged and I'm doing weird stuff for no reason I can ascertain", people often start happily explaining why it is an excellent idea for the king of the brain who has been replaced with a zombie robot during the brain damage to start lumbering around moaning loudly and smashing things at random.
Yvain's post The Apologist and the Revolutionary from a couple of years ago had some fascinating and mind-boggling discussion of other bizarre things that result from particular brain damage.
"Our moods are so unstable because we are only chemicals in a saline solution - not entries in a ledger or words in a book."
Is this true? Naive Googling yields this, which suggests (non-authoritatively) that blood sugar and moods are indeed linked (in diabetics, but it's presumably true in the general population). However, despair is not noted and the effects generally seem milder than that (true despair is a rather powerful emotion!)
Blood sugar is very closely linked to self-control, including suppression of emotion. While this may appear to be a different thing, it isn't: when you include feedback loops and association spirals, a transient, weak emotional distraction can become deep and overwhelming if normal modes of suppression fail.
"He [H.G. Wells] has abandoned the sensational theory with the same honourable gravity and simplicity with which he adopted it. Then he thought it was true; now he thinks it is not true. He has come to the most dreadful conclusion a literary man can come to, the conclusion that the ordinary view is the right one. It is only the last and wildest kind of courage that can stand on a tower before ten thousand people and tell them that twice two is four."

I was interested in the context here. Chesterton was referencing Wells' original belief that the classes would differentiate until the upper class ate the lower class. Wells changed his mind to believe the classes would merge.

What is the aim of philosophy? To be clear-headed rather than confused; lucid rather than obscure; rational rather than otherwise; and to be neither more, nor less, sure of things than is justifiable by argument or evidence. That is worth trying for.

Already I had learned from thee that because a thing is eloquently expressed it should not be taken to be as necessarily true; nor because it is uttered with stammering lips should it be supposed false. Nor, again, is it necessarily true because rudely uttered, nor untrue because the language is brilliant. Wisdom and folly both are like meats that are wholesome and unwholesome, and courtly or simple words are like town-made or rustic vessels — both kinds of food may be served in either kind of dish.

... People usually don't know why they vote for the candidates they choose to vote for, and are not particularly good at assessing how something influenced that vote -- let alone how some hypothetical future event would influence them.
...if you ask voters, it turns out that some will tell you that they would be more likely, and a somewhat larger number will tell you that they'll be less likely, to vote for someone with a Trump endorsement. Hey, reporters: don't believe those polls! You can take it as a measure of what respondents think about Trump, if you care about such things, but there's no reason to believe that this kind of self-reporting about vote choice is meaningful at all, and it shouldn't be included in stories about a Trump endorsement as if it was meaningful.
...The bottom line here is that polling is a really good tool for reporters to use in many cases, but remember: what polling tells you for sure is only what people will say if they're asked a question by a pollster.

Any time you say something is "more likely" than something else, that an explanation is "improbable," or "almost certainly true," or "implausible," and so on, you are making mathematical statements. Any time something is "more" than something else, that's math.
I’ve very often made mistakes in my physics by thinking the theory isn’t as good as it really is, thinking that there are lots of complications that are going to spoil it — an attitude that anything can happen, in spite of what you’re pretty sure should happen.

I may say that this is the greatest factor—the way in which the expedition is equipped—the way in which every difficulty is foreseen, and precautions taken for meeting or avoiding it. Victory awaits him who has everything in order — luck, people call it. Defeat is certain for him who has neglected to take the necessary precautions in time; this is called bad luck.

Paradoxes, like optical illusions, are often used by psychologists to reveal the inner workings of the mind, for paradoxes stem from (and amplify) dormant clashes among implicit sets of assumptions.
Judea Pearl (Causality)
...A paradox arises when two seemingly airtight arguments lead to contradictory conclusions—conclusions that cannot possibly both be true. It’s similar to adding a set of numbers in a two-dimensional array and getting different answers depending on whether you sum up the rows first or the columns. Since the correct total must be the same either way, the difference shows that an error must have been made in at least one of the two sets of calculations. But it remains to discover at which step (or steps) an erroneous calculation occurred in either or both of the running sums. There are two ways to rebut an argument. We might call them countering and invalidating.
+To counter an argument is to provide another argument that establishes the opposite conclusion.
+To invalidate an argument, we show that there is some step in that argument that simply does not follow from what precedes it (or we show that the argument’s premises—the initial steps—are themselves false).
If an argument starts with true premises, and if every step in the argument does follow, then the argument’s conclusion must be true. However, invalidating an argument—identifying an incorrect step somewhere—does not show that the
The tendency toward generalization doesn’t bother me in an of itself, rather, I’m focused on whether the proposition is true. But the hypocrisy gets tiresome sometimes, as people will fluidly switch from a cognitive style which accepts generalization to one which rejects it. A stereotype is often a generalization whose robustness you don’t want to accept. Negative generalities need context when they’re unpalatable, but no qualification is necessary when their truth is congenial.

..."Stay, 'tis just a figure!" Root laughed rather winningly, reaching out to touch Locke's shoulder.
"A faulty one," Daniel said, "for you are an alchemist."
"I am called an Alchemist. Within living memory, Daniel, everyone who studied what I—and you—study was called by that name. And most persons even today observe no distinction between Alchemy and the younger and more vigorous order of knowledge that is associated with your club."
"I am too exhausted to harry you through all of your evasions. Out of respect for your friends Mr. Locke, and for Leibniz, I shall give you the benefit of the doubt, and wish you well," Daniel said.
"God save you, Mr. Waterhouse."
"And you, Mr. Root. But I say this to you—and you as well, Mr. Locke. As I came in here I saw a map, lately taken from this house, burning in the fire. The map was empty, for it depicted the ocean—most likely, a part of it where no man has ever been. A few lines of latitude were ruled across that vellum void, and some legendary isles drawn in, with great authority, and where the map-maker could not restrain himself he drew phantastickal monsters. That map, to me, is A
I was pondering whether to cut the quote at this point, or to include the rest of the dialogue between natural philosopher Daniel Waterhouse and alchemist Enoch Root. I decided to cut the quote here firstly because otherwise it would be too long, and secondly because the rest of the dialogue does not have the same stirring, "yay science!", "yay modernity!" feeling of Daniel's tirade. But it is thought-provoking, so I include it below, with some reflections after it:
..." 'Tis a noble pursuit and I wish you Godspeed," Root said, "but remember the poles."
"The poles?"
"The north and south poles, where your meridians will come together—no longer parallel and separate, but converging, and all one."
"That is nothing but a figment of geometry."
"But when you build all your science upon geometry, Mr. Water-house, figments become real."
Daniel sighed. "Very well, perhaps we'll get back to Alchemy in the end—but for now, no one can get near the poles—unless you can fly there on a broom, Mr. Root—and I'll put my trust in geometry and not in the books of fables that Mr. Boyle and Sir Elias are sorting through belo
On the Outside View:
"Of course, if you want to, you can always come up with reasons why the lessons from the Neo-Sumerian Empire don't apply to you."
To explain: the Outside View is a powerful tool, but one sometime should reject it based on even more powerful factors from the Inside View, where one can be sure that one is in a new (or at least, different) reference class from the one being used in the Outside View. Of course, one may want to reject it based just on one like one's views...
This sometimes leads to a back-and-forth series of arguments over burdens of proof dubbed 'reference class tennis' where the two sides argue over what is the correct reference class which will either support or undermine a particular claim (is AGI in the reference class of "additional incremental innovation", which would undermine claims of significant danger/reward, or entire "regime changes", which would support the same claims? This is the game of reference class tennis which Eliezer and Hanson are arguing their way through in the link and related links).
Kaas is humorously parodying a side using an Outside View involving the Neo-Sumerian Empire, replying to the other side making the commonsense position - yours too ('what lessons?') - that the quasi-literate agricultural Neo-Sumerian Empire from 3000 years ago is not in a...
It may be expecting too much to expect most intellectuals to have common sense, when their whole life is based on their being uncommon -- that is, saying things that are different from what everyone else is saying. There is only so much genuine originality in anyone. After that, being uncommon means indulging in pointless eccentricities or clever attempts to mock or shock.

When people talk about the importance of democracy, it is never democracy as it has ever actually functioned, with the politicians that have actually been elected, and the policies that have actually been implemented. It is always democracy as people imagine it will operate once they succeed in electing "the right people" — by which they mean, people who agree almost completely with their own views, and who are consistent and incorruptible in their implementation of the resulting policies.
--Ben O'Neill, here
Considering the above quote can be used to criticize nearly any popular political position I don't think it is inherently mind-killing. Also since we all agree democracy is a good thing this isn't even very political. The original article and context obviously does make it somewhat political.
Paul Graham has written quite extensively of why some things are considered "threatening heresy", and other things mere eccentricity. Ultimately, he concludes that in order for something to be tabooed, it must be threatening to some group that is powerful enough to enforce the taboo, but not powerful enough that the can safely ignore what their critics say about them. Democracy is currently so entrenched in western civilization that it doesn't have to give a fuck if a few people here and there criticize it occasionally.
The same is true of people who call for a dictatorship or any non-democratic form of government. They also always imagine it will be governed by "the right people", and imagine all the things "the right people" could accomplish if freed from the need to listen to the "ignorant mob".

Bertie is a goldmine of rationality quotes.
The human understanding is no dry light, but receives an infusion from the will and affections; whence proceed sciences which may be called "sciences as one would." For what a man had rather were true he more readily believes. Therefore he rejects difficult things from impatience of research; sober things, because they narrow hope; the deeper things of nature, from superstition; the light of experience, from arrogance and pride, lest his mind should seem to be occupied with things mean and transitory; things not commonly believed, out of deference to the opinion of the vulgar. Numberless, in short, are the ways, and sometimes imperceptible, in which the affections color and infect the understanding.

Latest news: Burning Man blames game theory for their failure to understand basic supply and demand, hugely underprices tickets, 2/3 of buyers left in cold, Market Economics Fairy cries.
That's not a fair assessment of the organizers' skill level.
They seem to have a nice firm grip on the effect of fixed supply, fixed price, and increasing demand:
And in those regards, the ticket selection system worked as planned — but it created other unforeseen problems, and most of them boil down to an unpredicted, overwhelming level of demand. The impact of that demand is beyond what we projected when designing the system; even if we knew there were destined to be some people missing out, we didn’t expect nearly so many.
What they didn't predict was that the expectation of scarcity would further increase demand, creating a positive feedback loop. In their words:
there was a fair amount of over-registration – those who said “I need one but I’ll order two…” or “I’m not sure I’m going but I’ll get one just in case.” We can now see that some of that happened simply because the perception of scarcity drove fear and action for all of us.
So, they understand supply and demand (they just made a bad factual estimate of demand), and they didn't really understand game theory - but after they made their mistake they publicly admitted it, asked around to see what they did wrong, and proposed strategies for mitigating the mistake.
Why are we mocking them again?
In this particular case, not all attendees appear to be equally valuable to the event/other attendees. Giving priority to people who've organized cool things in the last few years may make sense.
Yes, this was my reaction - 'let the price float, and give transferrable vouchers to the people who do the most awesome stuff; if they object, well, that's why the vouchers are transferrable'. It's not much different from what they're already suggesting, telling the lucky ones to distribute excess tickets among people they like.
From the blog post:
No event organizer or ticket seller has solved scalping completely.
It seems pretty easy to solve: auction off all the tickets.
It improves the chance that further Market Economics will happen by rewarding people who produce it. It goes without saying that Market Economics is a terminal value to the Market Economics Fairy. If she was just interested in profit, she'd be starting a hedge fund instead of going around telling people about Market Economics.
Market Economics fairy should consider starting a hedge fund anyway and investing that money into a lobby group or other means of promoting Market Economics. I sincerely doubt emitting sparkles from her wand is where her comparative advantage lies.
What do you mean? The Market Economics Fairy is way better at emitting sparkles from her wand than anyone else, and has no special talent for managing hedge funds.
Well now you've proved that the Market Economics Fairy should quit her job and found a startup aimed at roboticizing sparkle production. I hope you're happy.
You're missing the unstated corollary to this, or any other discussion of scalpers: 'and prices have to be "reasonable" for whatever demographic we claim to serve or would prefer to serve'.
Hence, you get discussions of young girl singers unhappy that all these icky old men are paying hundreds of dollars for the tickets to her concert, even though the market doesn't clear at the $40 or $60 her preteen fans can spare. (And if an organization does let the price float to its natural level of hundreds of dollars, then you get shocked articles in the newspaper on 'ticket inflation' and angry letters to the editor about how in their day you could get in for a nickel...)
So there is the problem: The ideal of non-discrimination is not compatible with cases where the demographics of event-goers is itself a strong influence on the quality of the event for everyone involved.

A poem about decision trees:
I think that I shall never see
A decision complex as that tree—A tree with roots in ancient days
(At least as old as Reverend Bayes);A tree with trunk all gnarled and twisted
With axioms by Savage listed;A tree with branches sprouting branches
And nodes declaring what the chance is;A tree with flowers in its tresses
(Each flower made of blooming guesses);A tree with utiles at its tips
(Values gleaned from puzzled lips);A tree with stems so deeply nested
Intuition’s completely bested;A tree with branches in a tangle
Impenetrable from any angle;A tree that tried to tell us “should”
Although its essence was but “would”;A tree that did decision hold back
’Til calculation had it rolled back.Decisions are reached by fools like me,
But it took a consultant to make that tree.

"The Enlightenment is the moment at which explanatory knowledge is beginning to assume its soon-to-be-normal role as the most important determinant of physical events. At least it could be: we had better remember that what we are attempting – the sustained creation of knowledge – has never worked before. Indeed, everything that we shall ever try to achieve from now on will never have worked before. We have, so far, been transformed from the victims (and enforcers) of an eternal status quo into the mainly passive recipients of the benefits of relatively rapid innovation in a bumpy transition period. We now have to accept, and rejoice in bringing about, our next transformation: to active agents of progress in the emerging rational society – and universe."

Consider for a moment the first primitive amphibian that crawled up out of the sea around 400 million years ago. A contemporary biologist, had any existed, would certainly have classed this species as a rather unusual type of fish, for it would be far more closely related to certain kinds of fish than any other extant species. It is only in hindsight that we can see that it was not a fish, but the first representative of an entirely new class[41] of [vertebrates], the amphibians. But intelligence and tool-using are developments of comparable scope to the ability to breath air and move about on land. I therefore argue that human beings are not primates; we are not even mammals. Homo sapiens is a radical evolutionary phenomenon, the first representative of a new class of [vertebrates].

Once, as a junior doctor, I was walking through the hospital grounds when I noticed a patient sitting on a bench slashing his wrists with a broken bottle of vodka whose contents he had just drunk. I asked him to come into the hospital where I could sew him up (sobering him up was beyond my powers). He refused and I went to fetch a porter to drag him in by force.
By the time we returned, he had climbed up the fire escape (it was a Victorian building) and clambered over the railings on to a narrow ledge three storeys up, on which he was swaying drunkenly. The porter and I went up the fire escape: the man threatened to jump if we came nearer. We decided we had to make a grab for him; as we did so, he jumped. We held him suspended by his arms three storeys up. First he shouted, “Let me go, you bastards!” and then, “Help, I’m falling!” – a metaphor for the whole of human life, when you come to think of it.

Civilization is a stream with banks. The stream is sometimes filled with blood from people killing, stealing, shouting and doing the things historians usually record, while on the banks, unnoticed, people build homes, make love, raise children, sing songs, write poetry and even whittle statues.

[Mr. Furious tries to balance a hammer on his head]
Mr. Furious: Why am I doing this, again?
The Sphinx: When you can balance a tack hammer on your head, you will head off your foes with a balanced attack.
Mr. Furious: And why am I wearing the watermelon on my feet?
The Sphinx: [looks at the watermelon on Mr. Furious' feet] I don't remember telling you to do that.

[A] single qubit that you understand is better than a thousand qubits that you don’t.

Man gives indifferent names to one and the same thing from the difference of their own passions; as they that approve a private opinion call it opinion; but they that mislike it, heresy: and yet heresy signifies no more than private opinion.

Which occasions? If this were a rationality kata I would immediately ask, "What trigger condition does the person need to recognize that chains into using this technique?"
The strategy was really easy on the paper: no driver mistake, no pit stop mistake, no mechanic mistake, no engineer mistake ... it is so easy to write these things, but it is almost impossible to make it happen.
Dindo Capello, as quoted in Truth in 24 (2009 film).
When learning, you must know how to make the clear distinction between what is ideology and what is genuine knowledge.
There is no such thing as good and evil. There is what is right and what is bad, what is consistent and what is wrong.

That is the entire original quote, but not all felt like it belonged here. It's all part of the same, I think.
Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric.
No no, it's not that bad if you try to figure out where the commas go:
Not only are most eccentric opinions that have been held not accepted, those that gain the benefit of the eccentric opinions on their way to being accepted, are not necessarily those that first hold them.
So to rewrite with fewer negations:
Most eccentric opinions are not ultimately accepted. And when those rare eccentric opinions get accepted, their original accepters don't benefit much; but instead, the credit or rewards are reaped by those who accept them later in the acceptance process.
...the other, to change thy opinion, if there is anyone at hand who sets thee right and moves thee from any opinion. But this change of opinion must proceed only from a certain persuasion, as of what is just or of common advantage, and the like, not because it appears pleasant or brings reputation.
Marcus Aurelius, Meditations.
We produce 30-year projections of social security deficits and oil prices without realizing that we cannot even predict these for next summer --- our cumulative prediction errors for political and economic events are so monstrous that every time I look at the empirical record I have to pinch myself to verify that I am not dreaming. What is surprising is not the magnitude of our forecast errors, but absence of awareness of it.

Now you're looking for the secret. But you won't find it because, of course, you're not really looking. You don't really want to work it out. You want to be... fooled.

The context in the movie is a bit different, but it's a nice illustration of how people can let themselves be seduced by mysterious answers to mysterious questions, even when they purport to be "looking for the answer."
What makes a subject difficult to understand — if it is significant, important — is not that some special instruction about abstruse things is necessary to understand it. Rather it is the contrast between the understanding of the subject and what most people want to see. Because of this the very things that are most obvious can become the most difficult to understand. What has to be overcome is not difficulty of the intellect but of the will.
Ludwig Wittgenstein, Philosophical Occasions
The right to search for truth implies also a duty; one must not conceal any part of what one has recognized to be true.

Mandatory for science, generally advisable for anything else.

If you were smart enough to earn a Ph.D. in math, you should be able to learn how to program, once you overcome a possible psychological block. More important, let's make sure that our grad students are top-notch programmers, since very soon, being a good programmer will be a prerequisite to being a good mathematician.

You can only become intellectually an adult, so to speak, if you break through domain dependence.
Taleb runs an interesting Facebook, but if you don't want to get a Facebook account, I expect that a lot of this material will be in his upcoming book about anti-fragility (systems which get stronger when stressed).
I just realized that his domain dependence is equivalent to Rand's "concrete-bound mentality"-- in both cases, it's getting stuck on a single example rather than seeing general principles.

This quote hasn't gotten any karma yet-- it isn't funny, and it seems so obvious as to almost not be worth saying.
Still, I suspect that a lot of trouble is caused by ignoring that advice.
...We want to stand upon our own feet and look fair and square at the world -- its good facts, its bad facts, its beauties, and its ugliness; see the world as it is and be not afraid of it. Conquer the world by intelligence and not merely by being slavishly subdued by the terror that comes from it. ... We ought to stand up and look the world frankly in the face. We ought to make the best we can of the world, and if it is not so good as we wish, after all it will still be better than what these others have made of it in all these ages. A good world needs know
I needed reinforcements. "Look," I said, "four billion people believe in some sort of God and free will. They can't all be wrong."
"Very few people believe in God," he replied.
I didn't see how he could deny the obvious. "Of course they do. Billions of people believe in God."
The old man leaned toward me, resting a blanketed elbow on the arm of his rocker.

...Methodologically speaking, we must be careful to prevent valid insights from degenerating into fantasies and superstition, and not develop the tendency to see an occult background everywhere and at all costs. In this regard, every assumption we make must have the character of what are called "working hypotheses" in scientific research - as when something is admitted provisionally, thus allowing the gathering and arranging of a group of apparently isolated facts, only to confer on them a character not of hypothesis but of truth when, at the end o
Within ten days thou wilt seem a god to those to whom thou art now a beast and an ape, if thou wilt return to thy principles and to worshiping of reason
Marcus Aurelius, Meditations.
The intended listener must be doing an awful lot of stuff they already know is wrong. Ten days is a pretty short period of time to impress people as a god, and it usually requires more training and practice to get there. Heck, I still only impress people as a god around 10% of the time, and it took me 17 years to get here from when I first dedicated myself to rationality.

Who cares about "sometimes" when making a decision? What counts is the expectation, what happens on average.
Yes, sometimes investing all your savings in a single high-risk stock picked at random while drunk works better than listening to various experts, researching the relevant literature and diversifying your investments. That doesn't mean it's a good idea.
