100 Quotes About Rationality

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

Now that science has helped us to overcome the awe of the unknown in nature, we are the slaves of social pressures of our own making. When called upon to act independently, we cry for patterns, systems, and authorities. If by enlightenment and intellectual progress we mean the freeing of man from superstitious belief in evil forces, in demons and fairies, in blind fate--in short, the emancipation from fear--then denunciation of what is currently called reason is the greatest service reason can render. Max Horkheimer

Action is the activity of the rational soul, which abhors irrationality and must combat it or be corrupted by it. When it sees the irrationality of others, it must seek to correct it, and can do this either by teaching or engaging in public affairs itself, correcting through its practice. And the purpose of action is to enable philosophy to continue, for if men are reduced to the material alone, they become no more than beasts. Iain Pears

One of chief pieces of advice I give to aspiring rationalists is "Don't try to be clever." And, "Listen to those quiet, nagging doubts." If you don't know, you don't know what you don't know, you don't know how much you don't know, and you don't know how much you needed to know. Eliezer Yudkowsky

Considering he was neither priest nor scholar, the young man gave sensible, thoughtful replies -- the more so, perhaps, for being untrained, for he had not learned what he should believe or should not believe. Present a statement to him in flagrant contradiction to all Christian doctrine and he could be persuaded to agree on its good sense, unless he remembered it was the sort of thing of which pyres are made for the incautious. Iain Pears

Happiness is not to be achieved at the command of emotional whims. Happiness is not the satisfaction of whatever irrational wishes you might blindly attempt to indulge. Happiness is a state of non-contradictory joy–a joy without penalty or guilt, a joy that does not clash with any of your values and does not work for your own destruction, not the joy of escaping from your mind, but of using your mind's fullest power, not the joy of faking reality, but of achieving values that are real, not the joy of a drunkard, but of a producer. Happiness is possible only to a rational man, the man who desires nothing but rational goals, seeks nothing but rational values and finds his joy in nothing but rational actions. . Ayn Rand

Life is fundamentally a mental state. We live in a dream world that we create. Whose life is truer, the rational man of action pursuing practical goals of personal happiness and wealth or the philosophic man who lives in a world of theoretical and metaphysical ideas? We ascribe the value quotient to our lives by making decisions that we score as either valid or invalid based upon our personal ethics and how we think and behave. Kilroy J. Oldster

Most reject the more repugnant or indefensible dogmas while still holding onto some core belief. Many believers will proudly describe themselves as "reasonable" or "rational" based on how little of their religion they still embrace versus how much they now reject. I think it's funny when people realize that the less you believe the more reasonable you are, but they stop before they reach the logical conclusion. Aron Ra

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

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

When..did it become irrational to dislike religion, any religion, even to dislike it vehemently? When did reason get redescribed as unreason? When were the fairy stories of the superstitious placed above criticism, beyond satire? A religion was not a race. It was an idea, and ideas stood (or fell) because they were strong enough (or too weak) to withstand criticism, not because they were shielded from it. Strong ideas welcomed dissent. Salman Rushdie

When confronted by a ‘believer’ it is easy for me to contrast the views of the skeptic with those of the rationalist. I simply reach into my pocket and pull out my change. Holding a quarter aloft, I say, ‘This is a most remarkable coin, for it is heavier than all the sins of humanity committed since the beginning of the human race.’ I then hold up a nickel and say, ‘This coin is even more amazing, as it is brighter and shinier than the flames that proceeded from the Burning Bush discovered on Mt. Sinai by Moses.’Then I raise a penny and state, ‘This portrait of President Lincoln is more realistic and true-to-life than any portrait of Satan ever painted.’ And finally, I hold out a bright, shiny dime and say, ‘And this dime is the most amazing of all because it is heavier and contains more precious metals than all the gold bricks in the streets of Heaven.’I end with ‘Give to Caesar what is his, and hold the rest of it dear–for it is all you see and touch–and the Christian god can take care of all his things, for they amount to less than this 41 cents I hold here in my hand. . E. HaldemanJulius

You can't distinguish your group by doing things that are rational and believing things that are true. If you want to set yourself apart from other people you have to do things that are arbitrary and believe things that are false. Paul Graham

Though he never actually joined it, he was close to some civilian elements of the Democratic Front for the Liberation of Palestine, which was the most Communist (and in the rather orthodox sense) of the Palestinian formations. I remember Edward once surprising me by saying, and apropos of nothing: 'Do you know something I have never done in my political career? I have never publicly criticized the Soviet Union. It’s not that I terribly sympathize with them or anything–it's just that the Soviets have never done anything to harm me, or us.' At the time I thought this a rather naïve statement, even perhaps a slightly contemptible one, but by then I had been in parts of the Middle East where it could come as a blessed relief to meet a consecrated Moscow-line atheist-dogmatist, if only for the comparatively rational humanism that he evinced amid so much religious barking and mania. It was only later to occur to me that Edward's pronounced dislike of George Orwell was something to which I ought to have paid more attention. . Christopher Hitchens

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

.It is asking a great deal of a man, who has learnt to regulate his everyday affairs in accordance with the rules of experience and with due regard to reality, that he should entrust precisely what affects him most nearly to the care of an authority which claims as its prerogative freedom from all the rules of rational thought. Sigmund Freud

Experience cannot beat logic, and interpretations of observational evidence which are not in line with the laws of logical reasoning are no refutation of these but the sign of a muddled mind (or would one accept someone’s observational report that he had seen a bird that was red and non-red all over at the same time as a refutation of the law of contradiction rather than the pronouncement of an idiot?). HansHermann Hoppe

For the most part, people strenuously resist any redefinition of morality, because it shakes them to the very core of their being to think that in pursuing virtue they may have been feeding vice, or in fighting vice they may have in fact been fighting virtue. Stefan Molyneux

Believing that there is a conflict between rationality and spirituality is like believing that there is a conflict between knowledge and inspiration. Unknown

[S]cience has contributed a great deal to war and violence, and people well trained in science are sometimes not entirely rational and are even dogmatic. We have to find a way to teach reflectively, not just scientifically. Nel Noddings

Then you get the wrong answer and you can't go to the Moon that way! Nature isn't a person, you can't trick them into believing something else, if you try to tell the Moon it's made of cheese you can argue for days and it won't change the Moon! What you're talking about is rationalization, like starting with a sheet of paper, moving straight down to the bottom line, using ink to write 'and therefore, the Moon is made of cheese', and then moving back up to write all sorts of clever arguments above. But either the Moon is made of cheese or it isn't. The moment you wrote the bottom line, it was already true or already false. Whether or not the whole sheet of paper ends up with the right conclusion or the wrong conclusion is fixed the instant you write down the bottom line. . Eliezer Yudkowsky

Some information is classified legitimately; as with military hardware, secrecy sometimes really is in the national interest. Further, military, political, and intelligence communities tend to value secrecy for its own sake. It's a way of silencing critics and evading responsibility - for incompetence or worse. It generates an elite, a band of brothers in whom the national confidence can be reliably vested, unlike the great mass of citizenry on whose behalf the information is presumably made secret in the first place. With a few exceptions, secrecy is deeply incompatible with democracy and with science. Carl Sagan

It is significant comment on the victory of science over magic that were someone to say ‘if I put this pill in your beer it will explode, ’ we might believe them; but were they to cry ‘if I pronounce this spell over your beer it will go flat, ’ we should remain incredulous and Paracelsus, the Alchemists, Aleister Crowley and all the Magi have lived in vain. Yet when I read science I turn magical; when I study magic, scientific. Cyril Connolly

The human has not one but two births — first, when a person is born from the mother’s womb, and second, when that person rises from the socio-culturally imposed cocoon of prejudices and ignorance. Abhijit Naskar

It's hard to imagine a more extraordinary claim than that some hidden intelligence created a universe of more than a hundred billion galaxies, each containing more than a hundred billion stars, and then waited more than 13.7 billion years until a planet in a remote corner of a single galaxy evolved an atmosphere sufficiently oxygenated to support life, only to then reveal his existence to an assortment of violent tribal groups before disappearing again. Lawrence M. Krauss

It was a fairy tale, no fooling. It was unreality becoming real. This frightened her. Because people don't care for unreality becoming real. It pricks their well-fed minds, you see, with something like a hunger pang. They prefer the logical stuffiness of expectancy. It is only at certain times that they weaken, letting imagination in. That's the time to get them. (“The Disinheritors”) Richard Matheson

Like all people who have known rough times, light-heartedness seemed to her too irrational and inconsequent to be indulged in except as a reckless dram now and then; for she had been too early habituated to anxious reasoning to drop the habit suddenly.. Her triumph was tempered by circumspection, she had still that field-mouse fear of the coulter of destiny despite fair promise, which is common among the thoughtful who have suffered early from poverty and oppression. Thomas Hardy

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

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

If we are ever going to achieve a rational approach to organizing our affairs, we have to dignify the process of admitting to being wrong. It doesn't help matters at all if the media, or your friends, accuse you of "flip-flopping" when you change your mind. Changing our minds is our hope for the future. Brian Eno

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

Elinor agreed to it all, for she did not think he deserved the compliment of rational opposition. Jane Austen

Rationality attracts conscientious humans, whereas mysticism attracts fools. Abhijit Naskar

A narrow hallway is all that separates rational from irrational, creativity from insanity, and intelligence from stupidity. Kilroy J. Oldster

If God meant for people to fly, He would have given them brains. Robert A. Heinlein

There is no history of mankind, there is only an indefinite number of histories of all kinds of aspects of human life. And one of these is the history of political power. This is elevated into the history of the world. But this, I hold, is an offence against every decent conception of mankind. It is hardly better than to treat the history of embezzlement or of robbery or of poisoning as the history of mankind. For the history of power politics is nothing but the history of international crime and mass murder. Karl Popper

You are modern humans of the civilized world. And modern humans rise beyond all laws and superstitions of the society. They help their fellow beings to rise from the ashes of ignorance, illusion and fear. Abhijit Naskar

The New Man means to develop all the three dimensions of being, all the three doors to God: the head, the dimension of thinking, logic and reason, the heart - the dimension of joy, trust, intuition, relationships, beauty, creativity and a sense of unity in love and the being, the dimension of meditation, silence, emptiness and oneness with life. The first level of the head is the dimension of ideas, intellect, hypothesis, theories, logic, analysis, rationality and dualistic thinking. The first level is the level of the mind, which means a continuous oscillation like a pendulum between the mind's memories of the past and the ideas, dreams and expectations of the future. The second level of the heart is the dimension of joy, acceptance, trust, understanding, trust, friendship, intuition, empathy, creativity, compassion, humor, playfulness and a sense of unity in love. The third level of being is the dimension of presence, awareness, meditation, silence, emptiness and wholeness. The third level is our connection with our inner life source. Swami Dhyan Giten

People who have cut their teeth on philosophical problems of rationality, knowledge, perception, free will and other minds are well placed to think better about problems of evidence, decision making, responsibility and ethics that life throws up. Simon Blackburn

The goal of argumentation is to make a case so forceful (note the metaphor) that skeptics are coerced into believing it–they are powerless to deny it while still claiming to be rational. In principle, it is the ideas themselves that are, as we say, compelling, but their champions are not always averse to helping the ideas along with tactics of verbal dominance, among them intimidation (“Clearly . . .”), threat (“It would be unscientific to . . .”), authority (“As Popper showed . . .”), insult (“This work lacks the necessary rigor for . . .”), and belittling (“Few people today seriously believe that . . .”). Perhaps this is why H. L. Mencken wrote that “college football would be more interesting if the faculty played instead of the students. Steven Pinker

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

No validation of our rationality - of our very sanity - can be accomplished using our rationality itself. How can a person operating within a system of beliefs, including beliefs about beliefs, get outside that system to determine whether it is rational? If your entire system becomes infected with madness, including the very rules by which you reason, then how can you ever reason your way out of your madness? . Rebecca Goldstein

Melancholy is an escape not from reality, but unreality of the world. Raheel Farooq

The more rational we are, the more emotional we can be. Nino Gruettke

The sexual mechanisms of the two genders are just not compatible, that’s the horrible truth of it. (..)This is a truth we dare not acknowledge these days - because sameness is our religion and heretics are no more welcome now than they ever were - but I’m going to acknowledge it, because I’ve always felt that humility before the facts is the only thing that keeps a rational man together. Be humble in the face of facts, and proud in the face of opinions, as George Bernard Shaw once said. He didn’t, actually. I just wanted to put some authority behind this observation of mine, because I know you’re not going to like it. Hugh Laurie

Never trust books on the question of whether or not to trust your rational thinking. Trust your rational thinking on the question of whether or not to trust the books. Abhijit Naskar

A bitter thing cannot be made sweet. The taste of anything can be changed. But poison cannot be changed into nectar. B.R. Ambedkar

A man who does not question his own judgment, society, and who flourishes between deceit and bewilderment, fails his moral responsibility as a rational being. Duop Chak Wuol

Empathy is the sunlight to the vampire of culture. Stefan Molyneux

When the experts’ scientific knowledge is legitimated in terms of being rational, logical, efficient, educated, progressive, modern, and enlightened, what analogies can other segments of society. .. utilize to challenge them? Martin Guevara Urbina

Because the way people are built, Hermione, the way people are built to feel inside -" Harry put a hand over his own heart, in the anatomically correct position, then paused and moved his hand up to point toward his head at around the ear level, "- is that they hurt when they see their friends hurting. Someone inside their circle of concern, a member of their own tribe. That feeling has an off-switch, an off-switch labeled 'enemy' or 'foreigner' or sometimes just 'stranger'. That's how people are, if they don't learn otherwise. . Eliezer Yudkowsky

As understanding deepens, the further removed it becomes from knowledge. C.g. Jung

If you're rational you don't get to believe whatever you want to believe. Michael Huemer

Lies don't make you happy. They just make you lie about being happy. Stefan Molyneux

That which does not come by logic, does not leave by logic. Raheel Farooq

Anyone who engages in the practice of psychotherapy confronts every day the devastation wrought by the teachings of religion. Nathaniel Branden

In any culture, subculture, or family in which belief is valued above thought, and self-surrender is valued above self-expression, and conformity is valued above integrity, those who preserve their self-esteem are likely to be heroic exceptions. Nathaniel Branden

The true self is that which is in touch with reality. The false self is the aspects of your personality that are adapted to threats and no longer consciously recognizes either the adaptation or the threat. Stefan Molyneux

Tribalism is an addiction that is driven by false beliefs that need to be reflected back to be perceived as true. Stefan Molyneux

One of my colleagues in Duke, Ralph Keeney, noted that America's top killer isn't cancer or heart disease, nor is it smoking or obesity. It's our inability to make smart choices and overcome our own self-destructive behaviours. Ralph estimates that about half of us will make a lifestyle decision that will ultimately lead us to an early grave. And as if this were not bad enough, it seems that the rate at which we make these deadly decisions is increasing at an alarming pace. I suspect that over the next few decades, real improvements in life expectancy and quality are less likely to be driven by medical technology than by improved decision making. Since focusing on long-term benefits is not our natural tendency, we need to more carefully examine the cases in which we repeatedly fail, and try to come up with some remedies for these situations. For an overweight movie loved, the key might be to enjoy watching a film while walking on the treadmill. The trick is to find the right behavioural antidote for each problem. By pairing something that we love with something that we dislike but that is good for us, we might be able to harness desire with outcome - and thus overcome some of the problems with self-control we face every day. Dan Ariely

Many of the cataclysmic leadership failures were failures of rationality. The pendulum of leadership development needs to swing back toward the rational: strategy, creativity, foresight, decision-making, and analytics. Paul Gibbons

Mood evidently affects the operation of System 1: when we are uncomfortable and unhappy, we lose touch with our intuition. These findings add to the growing evidence that good mood, intuition, creativity, gullibility, and increased reliance on System 1 form a cluster. At the other pole, sadness, vigilance, suspicion, an analytic approach, and increased effort also go together. A happy mood loosens the control of System 2 over performance: when in a good mood, people become more intuitive and more creative but also less vigilant and more prone to logical errors. Daniel Kahneman

The Hedonistic Imperative outlines how genetic engineering and nanotechnology will abolish suffering in all sentient life. This project is ambitious but technically feasible. It is also instrumentally rational and ethically mandatory. The metabolic pathways of pain and malaise evolved only because they once served the fitness of our genes. They will be replaced by a different sort of neural architecture. States of sublime well-being are destined to become the genetically pre-programmed norm of mental health. The world's last aversive experience will be a precisely dateable event. . David Pearce

You have to choose your future regrets. Christopher Hitchens

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

Culture makes lies plausible through exposure to time. It makes prejudice seem like physics intergenerationally. It is therefore the most dangerous opponent of philosophy, because it feels the most credible to the average person. Stefan Molyneux

For, from the time that the Bishop of Rome had gotten to be acknowledged for bishop universal, by pretence of succession to St. Peter, their whole hierarchy, or kingdom of darkness, may be compared not unfitly to the kingdom of fairies; that is, to the old wives' fables in England concerning ghosts and spirits, and the feats they play in the night. And if a man consider the original of this great ecclesiastical dominion, he will easily perceive that the papacy is no other than the ghost of the deceased Roman Empire, sitting crowned upon the grave thereof: for so did the papacy start up on a sudden out of the ruins of that heathen power. Thomas Hobbes

Education levels are highly and negatively correlated to religious belief. In other words, ignorance is bliss. Cesar Nascimento

Intellectually, what is stimulating to a young man is a problem of obvious practical importance. A young man learning economics, for example, ought to hear lectures from individualists and socialists, protectionists and free-traders, inflationists and believers in the gold standard. He ought to be encouraged to read the best books of the various schools, as recommended by those who believe in them. This would teach him to weigh arguments and evidence, to know that no pinion is certainly right, and to judge men by their quality rather than by their consonance with preconceptions. . Bertrand Russell

If we start to think about trust as a public good (like clean air and water), we see that we can all benefit from higher levels of trust in terms of communicating with others, making financial transitions smoother, simplifying contracts, and many other business and social activities. Without constant suspicion, we can get more out of our exchanges with others while spending less time making sure that others will fulfill their promises to us. Yet as the tragedy of commons exemplifies, in the short term it is beneficial for each individual to violate and take advantage of the established trust. I suspect that most people and companies miss or ignore the fact that trust is an important public resource and that losing it can have long-term negative consequences for everyone involved. It doesn't take much to violate trust. Just a few bad players in the market can spoil it for everyone else. Dan Ariely

And when the Duke of Alva ordered three hundred Citizens to be put to Death together at Antwerp, a Lady who saw the Sight was presently afterwards deliver'd of a Child without a Head. So lives the Power of Imagination even in this Rationall Age. Peter Ackroyd

If we were rational enough to judge what we are fed based on what we are fed, those in the business of selling us hope (i.e., public speakers, presidents, priests, etc.) wouldn't wear suits. Mokokoma Mokhonoana

What a paradox it is, the sane causes more problems than the insane! It is! The real problems of the world do not come from the insane but, the sane! Ernest Agyemang Yeboah

Her endeavor was misguided and wrong and maybe plain crazy, akin to someone waking up one day and deciding he’s going to scale Kilimanjaro because he can’t stop imagining the view from the top, the picture so arresting and beautiful that it too soon delivers him to a precarious ledge, where he can no longer turn back. And while it’s easy to say this is a situation to be avoided, isn’t this what we also fear and crave simultaneously, that some internal force which defies understanding might remake us into the people we dream we are? . Changrae Lee

Imperfect knowledge, incomplete assessment of feedback, limited memory and recall, as well as poor problem-solving skills result in a form of rationality that attains not optimal decisions but more or less satisfactory compromises between conflicting constraints. Manuel De Landa
