"Sometimes men come by the name of genius in the same way that certain insects come by the name of centipede; not because they have a hundred feet, but because most people cannot count above fourteen."

"People are mostly sane enough, of course, in the affairs of common life: the getting of food, shelter, and so on. But the moment they attempt any depth or generality of thought, they go mad almost infallibly. The vast majority, of course, adopt the local religious madness, as naturally as they adopt the local dress. But the more powerful minds will, equally infallibly, fall into the worship of some intelligent and dangerous lunatic, such as Plato, or Augustine, or Comte, or Hegel, or Marx."

"Muad'Dib learned rapidly because his first training was in how to learn. And the first lesson of all was the basic trust that he could learn. It's shocking to find how many people do not believe they can learn, and how many more believe learning to be difficult. Muad'Dib knew that every experience carries its lesson."

"What is wanted is not the will to believe, but the wish to find out, which is the exact opposite."

"I have now reigned about 50 years in victory or peace, beloved by my subjects, dreaded by my enemies, and respected by my allies. Riches and honors, power and pleasure, have waited on my call, nor does any earthly blessing appear to have been wanting to my felicity. In this situation, I have diligently numbered the days of pure and genuine happiness which have fallen to my lot. They amount to fourteen."

"Science is what we understand well enough to explain to a computer. Art is everything else we do. ... Science advances whenever an Art becomes a Science. And the state of the Art advances too because people always leap into new territory once they have understood more about the old."

"One can measure the importance of a scientific work by the number of earlier publications rendered superfluous by it."

-- David Hilbert

"The seeker after the truth is not one who studies the writings of the ancients and, following his natural disposition, puts his trust in them, but rather the one who suspects his faith in them and questions what he gathers from them, the one who submits to argument and demonstration, and not to the sayings of a human being whose nature is fraught with all kinds of imperfection and deficiency. Thus the duty of the man who investigates the writings of scientists, if learning the truth is his goal, is to make himself an enemy of all that he reads, and, applying his mind to the core and margins of its content, attack it from every side. He should also suspect himself as he performs his critical examination of it, so that he may avoid falling into either prejudice or leniency."

-- Alhazen (Abū 'Alī al-Hasan ibn al-Hasan ibn al-Haitham)

Once again, we are saddled with a Stone Age moral psychology that is appropriate to life in small, homogeneous communities in which all members share roughly the same moral outlook. Our minds trick us into thinking that we are absolutely right and that they are absolutely wrong because, once upon a time, this was a useful way to think. It is no more, though it remains natural as ever. We love our respective moral senses. They are as much a part of us as anything. But if we are to live together in the world we have created for ourselves, so unlike the one in which our ancestors evolved, we must know when to trust our moral senses and when to ignore them.

--Joshua Greene

Practically anything can go faster than Disc light, which is lazy and tame, unlike ordinary light. The only thing known to go faster than ordinary light is monarchy, according to the philosopher Ly Tin Wheedle. He reasoned like this: you can't have more than one king, and tradition demands that there is no gap between kings, so when a king dies the succession must therefore pass to the heir instantaneously. Presumably, he said, there must be some elementary particles—kingons, or possibly queons—that do this job, but of course succession sometimes fails if, in mid-flight, they strike an anti-particle, or republicon. His ambitious plans to use his discovery to send messages, involving the careful torturing of a small king in order to modulate the signal, were never fully expounded because, at that point, the bar closed.

It's a wonderful thing to be clever, and you should never think otherwise, and you should never stop being that way. But what you learn, as you get older, is that there are a few million other people in the world all trying to be clever at the same time, and whatever you do with your life will certainly be lost - swallowed up in the ocean - unless you are doing it with like-minded people who will remember your contributions and carry them forward. That is why the world is divided into tribes.

-- Neal Stephenson, The Diamond Age

I neglected to record from which character the quote came.

It's easy to put down the shallow concerns of life, but in a way they are what life is about. Deeper concerns that don't connect in any way to economic wealth, social status, physical pleasure, etc., are not really deep but pointless. The shallow concerns all pertain to the lowest common denominator of human life because they really are the basic fabric of everyone's life. They're concerns that everyone shares and that everyone can easily understand.

—Ben Kovitz, Shallowness

"Smart people believe weird things because they are skilled at defending beliefs they arrived at for non-smart reasons." - Michael Shermer

In the King-on-the-Mountain style of conversation, one person (the King) makes a provocative statement, and requires that others refute it or admit to being wrong. The King is the judge of whether any attempted refutation is successful. [...] The King's behavior comes down to "you can't stop me". By the rules of his game, no one can make him back down. He treats conversation as a negotiation with his opponent. If his opponent wants him to back down, it's his opponent's responsibility to make him back down, not his responsibility to do something to help his opponent. He himself feels no responsibility to learn or understand or cultivate his mind.

—Ben Kovitz, King on the Mountain

"Fierce battles are fought within the confines of our goal systems. Inside the closed walls the essence of right and wrong is at stake as the rebels engage the guards of the evolutionary past. After the violent confrontations, the old kings rejoice their triumph or get beheaded to become but ghosts of their former glory. And again and again our inner book of morals gets revised... — Nevertheless, whatever the outcome is, it is, by definition, good."

"No matter how the next forty-seven thousand years turn out, whether they are ages of liberty or tyranny, happiness or misery, by the time two hundred thousand million years are passed, the civilization that rules the sevagram will occupy basically the same area of the local galactic supercluster, and achieve roughly the same height of enlightenment and technical advancement. You are wasting my time with trifles."

Monroe Fieldbinder sees psychologist to bounce ideas off him. One of Fieldbinder's ideas is that the phenomenon of modern party-dance is incompatible with self-consciousness, makes for staggeringly unpleasant situations (obvious resource: Amherst/Mt. Holyoke mixer '68) for the all self-conscious person. Modern party-dance is simply writhing to suggestive music. It is ridiculous, silly to watch and excruciatingly embarrassing to perform. It is ridiculous, and yet absolutely everyone does it, so that it is the person who does not want to do the ridiculous thing who feels out of place and uncomfortable and self-conscious . . . in a word, ridiculous.

David Foster Wallace (The Broom Of The System, pg. 158)

On an advertisement for a fitness product: "WHAT'S STRONGER? YOU, or YOUR EXCUSES?"

Loyalty mods don't whisper propaganda in your skull. They don't bombard you with images of the object of devotion while stimulating the pleasure centres of your brain, or cripple you with pain and nausea if you stray from correct thought. They don't cloud your mind with blissful euphoria, or feverish zealotry; nor do they trick you into accepting some flawed but elegant piece of casuistry. No brainwashing, no conditioning, no persuasion. A loyalty mod isn't an agent of change; it's the end product, a fait accompli. Not a cause for belief, but belief itself, belief made flesh - or rather, flesh made into belief.

When I came across this quote, I was struck by its relevance to one of Eliezer's beisutsukai posts about finding the successor to quantum mechanics ("The Failures of Eld Science"; on a side note, are there any 'internal'/wikilinks to LW articles for us to use, instead of hardwiring lesswrong.com URLs?).

I meant to write a post on how interesting it is that we intellectually know that many of our current theories must be wrong, and even have pretty good ideas as to which ones, but we still cannot psychologically tackle them with the same energy as if we had some anomaly or paradox to explain, or have the benefit of hindsight. The students in Eliezer's story know that quantum mechanics is wrong; someone with a well-verified observation contradicting quantum mechanics knows that it is wrong (replace 'quantum' with 'classical' as you wish). They will achieve better results than a battalion of conventional QMists.

But nothing quite gelled.

I divide my officers into four classes; the clever, the lazy, the industrious, and the stupid. Most often two of these qualities come together. The officers who are clever and industrious are fitted for the highest staff appointments. Those who are stupid and lazy make up around 90% of every army in the world, and they can be used for routine work. The man who is clever and lazy however is for the very highest command; he has the temperament and nerves to deal with all situations. But whoever is stupid and industrious is a menace and must be removed immediately!

"Now, what I want is, Facts. Teach these boys and girls nothing but Facts. Facts alone are wanted in life. Plant nothing else, and root out everything else.

An anti-rationalist quote. Dickens believes there is more to life than rationality. Does his satire upon us here have any basis in reality?

I quoted this in another comment, but I think it deserves to be in here as well. It used to be in the rec.backcountry FAQ.

For an idea to have survived so long across so many cycles is indicative of its relative fitness. Noise, at least some noise, was filtered out. Mathematically, progress means that some new information is better than past information, not that the average of new information will supplant past information, which means that it is optimal for someone, when in doubt, to systematically reject the new idea, information, or method. Clearly and shockingly, always. -Nassim Nicholas Taleb, Fooled by Randomness p.52
