I've always loved the initial exchange between Gregory and Syme in "The Man Who Was Thursday".

Context: Gregory is an anarchist poet, Syme is claiming to be a poet of respectability, which Gregory maintains is impossible.

....The poet delights in disorder only. If it were not so, the most poetical thing in the world would be the Underground Railway."

"So it is," said Mr. Syme.

"Nonsense!" said Gregory, who was very rational when anyone else attempted paradox. "Why do all the clerks and navvies in the railway trains look so sad and tired, so very sad and tired? I will tell you. It is because they know that the train is going right. It is because they know that whatever place they have taken a ticket for that place they will reach. It is because after they have passed Sloane Square they know that the next station must be Victoria, and nothing but Victoria. Oh, their wild rapture! oh, their eyes like stars and their souls again in Eden, if the next station were unaccountably Baker Street!"

"It is you who are unpoetical," replied the poet Syme. "If what you say of clerks is true, they can only be as prosaic as your poetry. The rare, strange thing is to hit the mark; the gross, obvious thing is to miss it. We feel it is epical when man with one wild arrow strikes a distant bird. Is it not also epical when man with one wild engine strikes a distant station? Chaos is dull; because in chaos the train might indeed go anywhere, to Baker Street or to Bagdad. But man is a magician, and his whole magic is in this, that he does say Victoria, and lo! it is Victoria. No, take your books of mere poetry and prose; let me read a time table, with tears of pride. Take your Byron, who commemorates the defeats of man; give me Bradshaw, who commemorates his victories. Give me Bradshaw, I say!"

This one should help you empathize with other people more.

"Everyone has a secret world inside of them. All the people in the whole world, no matter how dull they seem on the outside, inside them they've got unimaginable, magnificent, wonderful, stupid, amazing worlds."

-Neil Gaiman

The usual touchstone, whether that which someone asserts is merely his persuasion -- or at least his subjective conviction, that is, his firm belief -- is betting. It often happens that someone propounds his views with such positive and uncompromising assurance that he seems to have entirely set aside all thought of possible error. A bet disconcerts him. Sometimes it turns out that he has a conviction which can be estimated at a value of one ducat, but not of ten. For he is very willing to venture one ducat, but when it is a question of ten he becomes aware, as he had not previously been, that it may very well be that he is in error. If, in a given case, we represent ourselves as staking the happiness of our whole life, the triumphant tone of our judgment is greatly abated; we become extremely diffident, and discover for the first time that our belief does not reach so far. Thus pragmatic belief always exists in some specific degree, which, according to differences in the interests at stake, may be large or may be small. - Immanuel Kant , The Critique of Pure Reason

It is easy to believe; doubting is more difficult. Experience and knowledge and thinking are necessary before we can doubt and question intelligently. Tell a child that Santa Claus comes down the chimney or a savage that thunder is the anger of the gods and the child and the savage will accept your statements until they acquire sufficient knowledge to cause them to demur. Millions in India passionately believe that the waters of the Ganges are holy, that snakes are deities in disguise, that it is as wrong to kill a cow as it is to kill a person - and, as for eating roast beef…that is no more to be thought of than cannibalism. They accept these absurdities, not because they have been proved, but because the suggestion has been deeply imbedded in their minds, and they have not the intelligence, the knowledge, the experience, necessary to question them. We smile…the poor benighted creatures! Yet you and I, if we examine the facts closely, will discover that the majority of our opinions, our most cherished beliefs, our creeds, the principles of conduct on which many of us base our very lives, are the result of suggestion, not reasoning… Prejudiced, biased, and reiterated assertions, not logic, have formulated our beliefs. - Dale Carnegie

The noble lord in this case, as in so many others, first destroys his opponent, and then destroys his own position afterwards. The noble lord is the Prince Rupert of parliamentary discussion: his charge is resistless, but when he returns from the pursuit he always finds his camp in the possession of the enemy.

Benjamin Disraeli, source, on the speeches of Lord Stanley. I often think of this quote regarding the effectiveness (or otherwise) of different kinds of rhetoric.

For context, Prince Rupert was a cavalry commander whose charges were extremely effective at shattering the opposing cavalry, but who was often unable to restrain his troops from going too far, and consequently lost a number of important battles in the English Civil War.

Knowledge and productivity are like compound interest. Given two people of approximately the same ability and one person who works ten percent more than the other, the latter will more than twice outproduce the former. The more you know, the more you learn; the more you learn, the more you can do; the more you can do, the more the opportunity - it is very much like compound interest. I don't want to give you a rate, but it is a very high rate. Given two people with exactly the same ability, the one person who manages day in and day out to get in one more hour of thinking will be tremendously more productive over a lifetime.

-Richard Hamming, You and Your Research

The same critical concept in two different disciplines:

"Of several responses made to the same situation, those which are accompanied or closely followed by satisfaction to the animal will, other things being equal, be more firmly connected with the situation, so that, when it recurs, they will be more likely to recur; those which are accompanied or closely followed by discomfort to the animal will, other things being equal, have their connections with that situation weakened, so that, when it recurs, they will be less likely to occur. The greater the satisfaction or discomfort, the greater the strengthening or weakening of the bond." - Edward Thorndike's Law of Effect, Animal Intelligence: Experimental Studies, 1911

"Public services are never better performed than when their reward comes in consequence of their being performed, and is proportioned to the diligence employed in performing them." - Adam Smith, The Wealth of Nations, 1776

But have you ever asked yourselves sufficiently how much the erection of every ideal on earth has cost? How much reality has had to be misunderstood and slandered, how many lies have had to be sanctified, how many consciences disturbed, how much "God" sacrificed every time? If a temple is to be erected a temple must be destroyed: that is the law - let anyone who can show me a case in which it is not fulfilled! - Friedrich Nietzsche, The Genealogy of Morals

Human laws aim to induce human beings to virtue little by little, not all at once. And so the laws do not immediately impose on the many imperfect citizens what already belongs to virtuous citizens, namely, that citizens abstain from everything evil. Otherwise, the imperfect citizens, unable to endure those commands, would erupt into worse evil things.

-Thomas Aquinas, Summa Theologica

Perhaps any sufficiently advanced logic is indistinguishable from stupidity. - Alex Tabarrok, The Rise of Opaque Intelligence

As readers, we remain in the nursery stage so long as we cannot distinguish between taste and judgment, so long, that is, as the only possible verdicts we can pass on a book are two: this I like; this I don't like.

For an adult reader, the possible verdicts are five: I can see this is good and I like it; I can see this is good but I don't like it; I can see this is good and, though at present I don't like it, I believe that with perseverance I shall come to like it; I can see that this is trash but I like it; I can see that this is trash and I don't like it.

~ W. H. Auden, A Certain World: A Commonplace Book

Meta: How is this supposed to be different from the existing rationality quotes thread?

Meta

The truth can be of use when you can see where falsehoods lay.

Don't quit on hopes or dreams when you have simply got to -

Chin up! Don't bet on sinking ships because they'll only drag you down!

You've got to keep on sailing even when you want to frown!

The world will keep on turning without matter where you land.

You might as well be running when your feet should hit the sand!

-Rainbow Dash, lyrics to Sinking Ships, a song from Bittersweet, a fan-made episode of MLP:FiM.

So far as this is the case, it is evident that government, by excluding or even by superseding individual agency, either substitutes a less qualified instrumentality for one better qualified, or at any rate substitutes its own mode of accomplishing the work, for all the variety of modes which would be tried by a number of equally qualified persons aiming at the same end; a competition by many degrees more propitious to the progress of improvement than any uniformity of system. - J.S. Mill, Principles of Political Economy with some of their Applications to Social Philosophy

It is thus that the private interests and passions of individuals naturally dispose them to turn their stocks towards the employments which in ordinary cases are most advantageous to the society. But if from this natural preference they should turn too much of it towards those employments, the fall of profit in them and the rise of it in all others immediately dispose them to alter this faulty distribution. Without any intervention of law, therefore, the private interests and passions of men naturally lead them to divide and distribute the stock of every society among all the different employments carried on in it as nearly as possible in the proportion which is most agreeable to the interest of the whole society. - Adam Smith, Wealth of Nations

On religion:

Faith is corrosive to the human mind. -Susan Blackmore

I've never really thought just how damaging blind faith was to my thought processes until I read this quote. It strikes a chord with me.

If you're offended by any word in any language, it’s probably because your parents were unfit to raise a child. They were too stupid. They should have been neutered. Because all it is is a sound you can make with your mouth. It’s not a weakness that you have naturally. When you come out of that pink ugly hole onto this planet, you're nothing but a gooey, shrinking, wrinkled ball of weakness. That’s all you are: you're weak, you're nothing but weak, and your parents look at that, and they think: “Not weak enough. We can make this thing even weaker by training it to react poorly to different sounds that you can make with your mouth.”

-- Doug Stanhope
