Rationality Quotes

“The problem with today’s world is that everyone believes they have the right to express their opinion AND have others listen to it.

The correct statement of individual rights is that everyone has the right to an opinion, but crucially, that opinion can be roundly ignored and even made fun of, particularly if it is demonstrably nonsense!”
― Brian Cox

“The passion for revenge should never blind you to the pragmatics of the situation. There are some people who are so blighted by their past, so warped by experience and the pull of that silken cord, that they never free themselves of the shadows that live in the time machine...

And if there is a kind thought due them, it may be found contained in the words of the late Gerald Kersh, who wrote:"... there are men whom one hates until a certain moment when one sees, through a chink in their armour, the writhing of something nailed down and in torment.”
― Harlan Ellison, The Essential Ellison: A 50 Year Retrospective

“In the Hindu religion, one can[not] have freedom of speech. A Hindu must surrender his freedom of speech. He must act according to the Vedas. If the Vedas do not support the actions, instructions must be sought from the Smritis, and if the Smritis fail to provide any such instructions, he must follow in the footsteps of the great men.
He is not supposed to reason. Hence, so long as you are in the Hindu religion, you cannot expect to have freedom of thought”
― B.R. Ambedkar

“Your strength as a rationalist is your ability to be more confused by fiction than by reality. If you are equally good at explaining any outcome, you have zero knowledge.”
― Eliezer Yudkowsky

“Does a man of sense run after every silly tale of hobgoblins or fairies, and canvass particularly the evidence? I never knew anyone, that examined and deliberated about nonsense who did not believe it before the end of his enquiries.”
― David Hume, The Letters of David Hume

“Reality is, you know, the tip of an iceberg of irrationality that we've managed to drag ourselves up onto for a few panting moments before we slip back into the sea of the unreal.”

“The world, viewed philosophically, remains a series of slave camps, where citizens – tax livestock – labor under the chains of illusion in the service of their masters.”
― Stefan Molyneux

“But there seems to have been an actual decline in rational thinking. The United States had become a place where entertainers and professional athletes were mistaken for people of importance. They were idolized and treated as leaders; their opinions were sought on everything and they took themselves just as seriously — after all, if an athlete is paid a million or more a year, he knows he is important … so his opinions of foreign affairs and domestic policies must be important, too, even though he proves himself to be both ignorant and subliterate every time he opens his mouth. (Most of his fans were just as ignorant and unlettered; the disease was spreading.)”
― Robert A. Heinlein, To Sail Beyond the Sunset

“I have no great fondness for the universe, but I do live there”
― Eliezer Yudkowsky, Harry Potter and the Methods of Rationality

― Abhaidev, The Influencer: Speed Must Have a Limit

“Since knowledge, thinking, and rational action are properties of the individual, since the choice to exercise his rational faculty or not depends on the individual, man’s survival requires that those who think be free of the interference of those who don’t. Since men are neither omniscient nor infallible, they must be free to agree or disagree, to cooperate or to pursue their own independent course, each according to his own rational judgment. Freedom is the fundamental requirement of man’s mind.

A rational mind does not work under compulsion; it does not subordinate its grasp of reality to anyone’s orders, directives, or controls; it does not sacrifice its knowledge, its view of the truth, to anyone’s opinions, threats, wishes, plans, or “welfare.” Such a mind may be hampered by others, it may be silenced, proscribed, imprisoned, or destroyed; it cannot be forced; a gun is not an argument. (An example and symbol of this attitude is Galileo.)

It is from the work and the inviolate integrity of such minds—from the intransigent innovators—that all of mankind’s knowledge and achievements have come. (See The Fountainhead.) It is to such minds that mankind owes its survival. (See Atlas Shrugged.)”
― Ayn Rand, Capitalism: The Unknown Ideal

“I am myself a dissenter from all known religions, and I hope that every kind of religious belief will die out. I do not believe that, on the balance, religious belief has been a force for good. Although I am prepared to admit that in certain times and places it has had some good effects, I regard it as belonging to the infancy of human reason, and to a stage of development which we are now outgrowing.”
― Bertrand Russell, Sceptical Essays

“In fact quite generally, commercial advertising is fundamentally an effort to undermine markets. We should recognize that. If you’ve taken an economics course, you know that markets are supposed to be based on informed consumers making rational choices. You take a look at the first ad you see on television and ask yourself … is that it’s purpose? No it’s not. It’s to create uninformed consumers making irrational choices. And these same institutions run political campaigns. It’s pretty much the same: you have to undermine democracy by trying to get uninformed people to make irrational choices.”
― Noam Chomsky, The Kind of Anarchism I Believe in, and What's Wrong with Libertarians

“Had reason ever created a poem, or a symphony, or a painting? If rationality can’t see things like the secret commonwealth, it’s because rationality’s vision is limited. The secret commonwealth is there. We can’t see it with rationality any more than we can weigh something with a microscope: it’s the wrong sort of instrument. We need to imagine as well as measure ...”
― Philip Pullman, The Secret Commonwealth

“The methods of increasing the degree of truth in our beliefs are well known; they consist in hearing all sides, trying to ascertain all the relevant facts, controlling our own bias by discussion with people who have the opposite bias, and cultivating a readiness to discard any hypothesis which has proved inadequate.”
― Bertrand Russell, Sceptical Essays

“There are some doubters even in the western villages. One woman told me last Christmas that she did not believe either in hell or in ghosts. Hell she thought was merely an invention got up by the priest to keep people good; and ghosts would not be permitted, she held, to go 'trapsin about the earth' at their own free will; 'but there are faeries,' she added, 'and little leprechauns, and water-horses, and fallen angels.' I have met also a man with a mohawk Indian tattooed upon his arm, who held exactly similar beliefs and unbeliefs. No matter what one doubts one never doubts the faeries, for, as the man with the mohawk Indian on his arm said to me, 'they stand to reason.' Even the official mind does not escape this faith. ("Reason and Unreason")”
― W.B. Yeats, The Celtic Twilight: Faerie and Folklore

“You have to be a light to yourself in a world that is utterly becoming dark.”
― Jiddu Krishnamurti
