Best of Rationality Quotes
'One day, Korzybski was giving a lecture to a group of students, and he interrupted the lesson suddenly in order to retrieve a packet of biscuits, wrapped in white paper, from his briefcase. He muttered that he just had to eat something, and he asked the students on the seats in the front row, if they would also like a biscuit. A few students took a biscuit.
"Nice biscuit, don't you think," said Korzybski, while he took a 2nd one. The students were chewing vigorously. Then he tore the white paper from the biscuits, in order to reveal the original packaging. On it was a big picture of a dog's head and the words "Dog Cookies."
The students looked at the package, and were shocked. Two of them wanted to vomit, put their hands in front of their mouths, and ran out of the lecture hall to the toilet.
"You see," Korzybski remarked, "I have just demonstrated that people don't just eat food, but also words, and that the taste of the former is often outdone by the taste of the latter."'
I think of this as a rationalist parable and not so much a quote. It has a lot of personal resonance since I often had dog biscuits with my tea when I was younger.
"CAESAR [recovering his self-possession]: Pardon him. Theodotus, he is a barbarian, and thinks that the customs of his tribe and island are the laws of nature."
--George Bernard Shaw, Caesar and Cleopatra (1898)
'One day when I was a junior medical student, a very important Boston surgeon visited the school and delivered a great treatise on a large number of patients who had undergone successful operations for vascular reconstruction.
At the end of the lecture, a young student at the back of the room timidly asked, “Do you have any controls?” Well, the great surgeon drew himself up to his full height, hit the desk, and said, “Do you mean did I not operate on half the patients?” The hall grew very quiet then. The voice at the back of the room very hesitantly replied, “Yes, that’s what I had in mind.” Then the visitor’s fist really came down as he thundered, “Of course not. That would have doomed half of them to their death.”
God, it was quiet then, and one could scarcely hear the small voice ask, “Which half?”'
Dr. E. E. Peacock, Jr., quoted in Medical World News (September 1, 1972), p. 45, as quoted in Tufte's 1974 book Data Analysis for Politics and Policy; http://www.marginalrevolution.com/marginalrevolution/2010/12/the-ethics-of-random-clinical-trials.html
"Perhaps the excellence of aphorisms consists not so much in the expression of some rare or abstruse sentiment, as in the comprehension of some obvious and useful truth in a few words.
We frequently fall into error and folly, not because the true principles of action are not known, but because, for a time, they are not remembered; and he may therefore be justly numbered among the benefactors of mankind who contracts the great rules of life into short sentences, that may be easily impressed on the memory, and taught by frequent recollection to recur habitually to the mind."
--Samuel Johnson, Rambler #175, November 19, 1751
"The conversation eventually turned to the fact that Palanpur farmers sow their winter crops several weeks after the date at which yields would be maximized. The farmers do not doubt that earlier planting would give them larger harvests, but no one, the farmer explained, is willing to be the first to plant, as the seeds on any lone plot would be quickly eaten by birds.
I asked if a large group of farmers, perhaps relatives, had ever agreed to sow earlier, all planting on the same day to minimize the losses. 'If we knew how to do that,” he said, looking up from his hoe at me, "we would not be poor.'"
--Microeconomics, pg 39, Samuel Bowles
"Whoso wishes to grasp God with his intellect becomes an atheist."
--Nikolaus Ludwig von Zinzendorf

"This achievement is often praised as a sign of the great superiority of modern civilization over the many faded and lost civilizations of the ancients. While our great skill lies in finding patterns of repetition under the apparent play of accident and chance, less successful civilizations dealt by appealing to supernatural powers for protection. But the voices of the gods proved ignorant and false; they have been silenced by the truth."
--James P. Carse, Finite and Infinite Games
"If we were bees, ants, or Lacedaemonian warriors, to whom personal fear does not exist and cowardice is the most shameful thing in the world, warring would go on forever.
But luckily we are only men - and cowards."
--Erwin Schrodinger, Mind and Matter
"Student: How can one realize his Self-nature? I know so little about the subject.
Yasutani: First of all, you must be convinced you can do so. The conviction creates determination, and the determination zeal.
But if you lack conviction, if you think 'maybe I can get it, maybe I can't', or even worse, 'This is beyond me!' - you won't awaken no matter how much you do zazen."

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 waste many hours each day being efficient."
"What is written without effort is in general read without pleasure."
--Dr. Samuel Johnson
"No, imbeciles! No! Fools and cretins, a book will not make a plate of soup; a novel is not a pair of boots; a sonnet is not a syringe; a drama is not a railway - those forms of civilization which have caused humanity to march on the road to progress.
By all the bowels of all the popes, past, present and future, no! Ten thousand times no!
You cannot make a hat out of a metonymy, and you cannot make a simile in the form of a bedroom slipper, and you cannot use an antithesis as an umbrella [...] An ode is, I have a feeling, too light a garment for the winter."
--Théophile Gautier, Preface (1834) to Gautier, Mademoiselle de Maupin (1835), http://berlin.wolf.ox.ac.uk/lists/quotations/quotations_by_ib.html
"Mortal danger is an effective antidote for fixed ideas."

"I thought a little [while in the isolation tank], and then I stopped thinking altogether. … incredible how idleness of body leads to idleness of mind. After two days, I’d turned into an idiot. That’s the reason why, during a flight, astronauts are always kept busy."
Oriana Fallaci as quoted in Rocket Men: The Epic Story of the First Men on the Moon, by Craig Nelson, which cites 'Fallici, Oriana If the Sun Dies. New York. Atheneum, 1967', seen on http://www.johndcook.com/blog/2010/12/11/after-two-days-id-turned-into-an-idiot/
"As a final practical maxim, relative to these habits of the will, we may, then, offer something like this: Keep the faculty of effort alive in you by a little gratuitous exercise every day. That is, be systematically ascetic or heroic in little unnecessary points, do every day or 2 something for no other reason than that you would rather not do it, so that when the hour of dire need draws nigh, it may find you not unnerved and untrained to stand the test. Asceticism of this sort is like the insurance which a man pays on his house and goods. The tax does him no good at the time, and possibly may never bring him a return. But if the fire does come, his having paid it will be his salvation from ruin."
--William James, The Principles of Psychology 1890, Chapter IV
"The person who takes the banal and ordinary and illuminates it in a new way can terrify. We do not want our ideas changed. We feel threatened by such demands. "I already know the important things!" we say. Then Changer comes and throws our old ideas away."
Chapterhouse Dune, Frank Herbert
"...for we judge ourselves by what we feel capable of doing, while others judge us by what we have already done."
--Henry Wadsworth Longfellow, Kavanagh ch. 1
"Here it is difficult as it were to keep our heads up, - to see that we must stick to the subjects of our every-day thinking, and not go astray and imagine that we have to describe extreme subtleties, which in turn we are after all quite unable to describe with the means at our disposal. We feel as if we had to repair a torn spider's web with our fingers."
Ludwig Wittgenstein, Philosophical Investigations 106
"For there is no error so crooked, but it hath in it some lines of truth;
Nor is any poison so deadly, that it serveth not some wholesome use."
"Of Truth in Things False", Proverbial Philosophy, Martin Farquhar Tupper
"O my friend, if we, leaving this war, could escape from age and death, I should not here be fighting in the van; but now, since many are the modes of death impending over us which no man can hope to shun, let us press on and give renown to other men, or win it for ourselves."
--Sarpedon, The Iliad, as quoted in Eric Drexler's Engines of Creation
"Normal humans don't interest me. If anyone here is an alien, a time traveler, slider, or an esper, then come find me! That is all."
--The Melancholy of Haruhi Suzumiya, vol 1
--George Bernard Shaw, A Treatise on Parents and Children (1910)
