Irrational Man Quotes & Sayings

The reasoning man who rejects the superstitions of simpletons necessarily becomes their enemy; he must expect as much and be prepared to laugh at the consequences. — Marquis De Sade

In every man there are two minds that work side by side, the one checking the other; thus emotion stands against reason, intellect corrects passion and first impressions act a little, but very little, before quick reflection. — Ford Madox Ford

Only a bet on the impossible makes sense. It is an act of faith and courage requiring an irrational leap over reason. A man wins simply by making such a bet. — William Kennedy

The bodies of irrational animals are bent toward the ground, whereas man was made to walk erect with his eyes on heaven, as though to remind him to keep his thoughts on things above. — Augustine Of Hippo

A real man does not think of victory or defeat. He plunges recklessly towards an irrational death. — Yamamoto Tsunetomo

Let me explain how such a thing might occasionally happen,' Goebbels said. 'All during the twelve years of the Weimar Republic our people were virtually in jail. Now our party is in charge and they are free again. When a man has been in jail for twelve years and he is suddenly freed, in his joy he may do something irrational, perhaps even brutal. Is that not a possibility in your country also?'
Ebbutt, his voice even, noted a fundamental difference in how England might approach such a scenario. 'If it should happen,' he said, 'we would throw the man right back in jail. — Erik Larson

If the transmigration of a soul takes place into a rational being, it simply becomes the soul of that body. But if the soul migrates into a brute beast, it follows the body outside, as a guardian spirit follows a man. For there could never be a rational soul in an irrational being. — Sallust

The problem is that spiritual answers cannot be deduced by human reason alone (1 Cor. 2:14). It's not that spiritual truth is irrational or illogical, but that human wisdom is defective, because it's tainted by man's sinfulness, and unable to perceive the things of God. — John F. MacArthur Jr.

All public interest' legislation (and any distribution of money taken by force from some men for the unearned benefit of others) comes down ultimately to the grant of an undefined undefinable, non-objective, arbitrary power to some government officials. The worst aspect of it is not that such a power can be used dishonestly, but that it cannot be used honestly. The wisest man in the world, with the purest integrity, cannot find a criterion for the just, equitable, rational application of an unjust, inequitable, irrational principle. — Ayn Rand

When irrational terror takes to itself the fiat of moral goodness somebody has to die ... No man lives who has not got a panic button, and when it is pressed by the clean white hand of moral duty, a certain murderous train is set in motion. — Arthur Miller

To struggle when hope is banished! To live when life's salt is gone! To dwell in a dream that's vanished! To endure, and go calmly on! The brave man is not he who feels no fear, For that were stupid and irrational; But he, whose noble soul its fear subdues, And bravely dares the danger nature shrinks from. — Joanna Baillie

Man, the rational animal, can put up with anything except what seems to him irrational; whatever is rational is tolerable. — Epictetus

As for me, you wonder why I am a socialist. I'll tell you. It is because socialism is inevitable; because the present rotten and irrational system cannot endure; because the day is past for your man on horseback. The slaves won't stand for it. They are too many, and willy-nilly they'll drag down the would-be equestrian before he gets astride. You can't get away from them, and you'll have to swallow the whole slave-morality. It's not a nice mess, I'll allow. But it's been a-brewing and swallow it you must. — Jack London

Man's life is a line that nature commands him to describe upon the surface of the earth, without his ever being able to swerve from it, even for an instant. He is born without his own consent; his organization does in nowise depend upon himself; his ideas come to him involuntarily; his habits are in the power of those who cause him to contract them; he is unceasingly modified by causes, whether visible or concealed, over which he has no control, which necessarily regulate his mode of existence, give the hue to his way of thinking, and determine his manner of acting. He is good or bad, happy or miserable, wise or foolish, reasonable or irrational, without his will being for any thing in these various states. — Paul Henri Thiry D'Holbach

Shall I go to Llandrindon, then?" she asked, hoping to provoke him.
"Yes."
Daisy scowled. "I wish you'd be consistent. A few minutes ago you were ready to make mincemeat of him."
"If you want him, I have no right to object."
"If you want me, you have every right to say something!" Daisy strode to the door. "Why does everyone always claim women are illogical when men are a hundred times more so? First they want something, then they don't, then they make irrational decisions based on secrets they won't explain and no one is supposed to question them because a man's word is final. — Lisa Kleypas

Man stands face to face with the irrational. He feels within him his longing for happiness and for reason. The absurd is born of this confrontation between the human need and the unreasonable silence of the world. — Albert Camus

Hell is a different place for each man, or each man has his own particular hell. My descent into the inferno is a descent into the irrational level of existence, where the instincts and blind emotions are loose, where one lives by pure impulse, pure fantasy, and therefore pure madness. No, that is not the inferno. — Anais Nin

I've always been sceptical about the notion that the market is a person you can engage in an argument with, and that that person is an intelligent, rational, well-intentioned person: it is fantasy. We know that ... the market is subject to irrational optimism and pessimism, and is vindictive ... You're dealing with a crazy man ... Having got what he wants he will still kill you. — Joseph Stiglitz

Daniel was slow to take up the cheer. But when he did, he meant it. This was politics. It was ugly, it was irrational, but it was preferable to war. Roger was being cheered because he had won. What did it mean to win? It meant being cheered. So Daniel huzzahed, as lustily as his dry pipes and creaky ribs would permit, and was astounded to see the way people came a-running: not only the Quality from their town-houses, but hooligans and Vagabonds from bonfire-strewn fields to the north, to throng around Roger and cheer him. Not because they agreed with his positions, or even knew who he was, but because he was plainly enough the man of the hour. — Neal Stephenson

Starbuck especially elucidates this peculiar division between physical and moral courage. The first mate, "while generally abiding firm in the conflict with seas, or winds, or whales, or any of the ordinary irrational horrors of the world, yet cannot withstand those more terrific, because spiritual terrors, which sometimes menace you from the concentrating brow of an enraged and mighty man."52 Starbuck is tormented by his complicity in what he foresees as Ahab's "impious end, but feel that I must help him to it." "But he drilled deep down," Starbuck exclaims, "and blasted all my reason out of me!"53 Moral cowardice like Starbuck's turns us into hostages. Mutiny is the only salvation for the Pequod's crew. And mutiny is our only salvation. — Chris Hedges

O, mighty, divinely delimited wisdom of walls, boundaries! I is perhaps the most magnificent of all inventions. Man ceased to be a wild animal only when he build the first wall. Men ceased to be a wild man only when we built the Green Wall, only when, by means of that wall, we isolated our perfect machine world from the irrational, ugly world of trees, birds, and animals ... — Yevgeny Zamyatin

Every man builds his world in his own image; he has the power to choose, but no power to escape the necessity of choice. If he abdicates his power, he abdicates the status of man, and the grinding chaos of the irrational is what he achieves as his sphere of existence - by his own choice. — Ayn Rand

Nor will arguments be of any use against a fascist who is narcissistically convinced of the supreme superiority of his Teutonism, if only because he operates with irrational feelings and not with arguments. Hence, it would be hopeless to try to prove to a fascist that black people and Italians are not racially "inferior" to the Teutons. He feels himself to be "superior," and that's the end of it. The race theory can be refuted only by exposing its irrational functions, of which there are essentially two: that of giving expression to certain unconscious and emotional currents prevalent in the nationalistically disposed man and of concealing certain psychic tendencies. — Wilhelm Reich

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

Looking down at the Chinese officer who was trying to gather his entrails with his hands. Suriyawong had the irrational thought that the man ought really to wash his organs before jamming them back into his abdomen. It was so unsanitary. — Orson Scott Card

It seems that life, in order to maintain itself, must revolt every so often against man's ceaseless attempts to master its irrational forces with his mind. — Otto Rank

In the search for meaning we must not forget that the gods (or God, for that matter) are a concept of the human mind; they are the creatures of man, not vice versa. They are needed and invented to give meaning and purpose to the struggle that is life on Earth, to explain strange and irregular phenomena of nature, haphazard events and, above all, irrational human conduct. They exist to bear the burden of all things that cannot be comprehended except by supernatural intervention or design. — Barbara Tuchman

No one doubts that an ordinary man can get on with this world: but we demand not strength enough to get on with it, but strength enough to get it on. Can he hate it enough to change it, and yet love it enough to think it worth changing? Can he look up at its colossal good without once feeling acquiescence? Can he look up at its colossal evil without once feeling despair? Can he, in short, be at once not only a pessimist and an optimist, but a fanatical pessimist and a fanatical optimist? Is he enough of a pagan to die for the world, and enough of a Christian to die to it? In this combination, I maintain, it is the rational optimist who fails, the irrational optimist who succeeds. He is ready to smash the whole universe for the sake of itself. — G.K. Chesterton

But the thing which in eminent instances signalizes so exceptional a nature is this: Though the man's even temper and discreet bearing would seem to intimate a mind peculiarly subject to the law of reason, not the less in heart he would seem to riot in complete exemption from that law, having apparently little to do with reason further than to employ it as an ambidexter implement for effecting the irrational. — Herman Melville

This crazy, blind beating of wings caused by man-made light ... this irrational connection between spiders, moths and light. If a law appeared without reason, like this, what would one believe in? — Kobo Abe

I'm reading a book that actually scares me. It is not a form of fear that is embodied in some irrational phobia of a specific object, living being, or an event, but a fear of words, of actions of beings towards one another, how one word or command wrongly distributed can destroy someone or many people. How following blindly into the paths of something you truly believe is right without any rationale to back it up or the thought of the consequences it can cause may blindly lead others to their death. How in that moment, thinking you're doing it for the right reasons, you ignore all the laws of nature that tell you that human life is sacred and that no one man's ideals can ever compensate for its loss. To have the power to destroy and cause suffering without much care. This is a fear of what humanity is turning into, and such a future truly scares me. — Aliaa El-Nashar

It began with one act of madness, and it ended with another. John Brown heard history's clock strike in the night and tried to hurry dawn along with gunfire; now John Wilkes Booth heard the clock strike, and he tried with gunfire to restore the darkness. Each man stood outside the human community, directed by voices the sane do not hear, and each kept history from going logically ... The line from Harper's Ferry to Ford's Theater is a red thread binding the immense disorder of the Civil War into an irrational sort of coherence. — Bruce Catton

As we grow older we become more conscious of the complexity, incoherence, and unreasonableness of human beings; this indeed is the only excuse that offers for the middle-aged or elderly writer, whose thoughts should more properly be turned to graver matters, occupying himself with the trivial concerns of imaginary people. For if the proper study of mankind is man it is evidently more sensible to occupy yourself with the coherent, substantial, and significant creatures of fiction than with the irrational and shadowy figures of real life. — W. Somerset Maugham

Even if it seems certain that you will lose, retaliate. Neither wisdom nor technique has a place in this. A real man does not think of victory or defeat. He plunges recklessly towards an irrational death. By doing this, you will awaken from your dreams. — Tsunetomo Yamamoto

Thus began Outrage from liveless things; but Discord first Daughter of Sin, among th' irrational, Death introduc'd through fierce antipathie: Beast now with Beast gan war, & Fowle with Fowle, And Fish with Fish; to graze the Herb all leaving, Devourd each other; nor stood much in awe Of Man, but fled him, or with count'nance grim Glar'd on him passing: these were from without The growing miseries, which ADAM saw Alreadie in part, though hid in gloomiest shade, To sorrow abandond, but worse felt within, And in a troubl'd Sea of passion tost, Thus to disburd'n sought with sad complaint. — John Milton

In fact a man in love or one consumed with hatred creates symbols for himself, as a superstitious man does, from a passion of conferring uniqueness on things or persons. A man who knows nothing of symbols is one of Dante's sluggards. This is why art mirrors itself in primitive rites or strong passions, seeking for symbols, revolving round the primitive taste for savagery, for what is irrational (blood and sex). — Cesare Pavese

Mark the babe not long accustomed to this breathing world; One that hath barely learned to shape a smile, though yet irrational of soul, to grasp with tiny finger - to let fall a tear; And, as the heavy cloud of sleep dissolves, To stretch his limbs, becoming, as might seem. The outward functions of intelligent man. — William Wordsworth

To me, all human behavior is unpredictable and, considering man's frailty ... and ... the ramshackle universe he functions in, it's ... all irrational. — William Faulkner

They scattered with no melody, no harmony, no rhythm to hold them. If music was emotion and emotion came from thought, then this was the scream of chaos, of the irrational, of the helpless, of man's self-abdication. — Ayn Rand

Man represses the irrational passions of destructiveness, hate, envy, revenge; he worships power, money, the sovereign state, the nation; while he pays lip service to the teachings of the great spiritual leaders of the human race, those of Buddha, the prophets, Socrates, Jesus, Mohammed-he has transformed these teachings into a jungle of superstition and idol-worship. How can mankind save itself from destroying itself by this discrepancy between intellectual-technical overmaturity and emotional backwardness? — Erich Fromm

Scientific education is based in the main on statistical truths and abstract knowledge and therefore imparts an unrealistic, rational picture of the world, in which the individual, as a merely marginal phenomenon, plays no role. The individual, however, as an irrational datum, is the true and authentic carrier of reality, the concrete man as opposed to the unreal ideal or "normal" man to whom the scientific statements refer. — C. G. Jung

To crush, to annihilate a man utterly, to inflict on him the most terrible of punishments so that the most ferocious murderer would shudder at it and dread it beforehand, one need only give him work of an absolutely, completely useless and irrational character. — Fyodor Dostoevsky

LADIES AND GENTLEMEN! YOU'VE READ ABOUT IT IN THE NEWSPAPERS! NOW, SHUDDER AS YOU OBSERVE, BEFORE YOUR VERY EYES, THAT MOST RAREAND RAGIC OF NATURE'S MISTAKES!
I GIVE YOU ... THE AVERAGE MAN!
PHYSICALLY UNREMARKABLE , IT HAS INSTEAD A DEFORMED SET OF VALUES.
NOTICE THE HIDEOUSLY BLOATED SENSE OF HUMANITY'S IMPORTANCE. THE CLUB-FOOTED SOCIAL CONSCIENCE AND THE WITHERED OPTIMISM.
IT'S CERTAINLY NOT FOR THE SQUEAMISH IS IT?
MOST REPULSIVE OF ALL , ARE ITS FRAIL AND USELESS NOTIONS OF ORDER AND SANITY. IF TOO MUCH WEIGHT IS PLACED UPON THEM ...
... THEY SNAP.
HOW DOES IT LIVE , I HEAR YOU ASK?
HOW DOES THIS POOR, PATHETIC SPECIMEN SURVIVE IN TODAY'S HARSH AND IRRATIONAL WORLD?
THE SAD ANSWER IS 'NOT VERY WELL. — Alan Moore

The source of man's rights is not divine law or a congressional law, but the law of identity. A is A _ and man is man. Rights are conditions of existence required by man's nature for his proper survival. If man is to live on earth, it is right for him to use his mind, it is right to act on his own free judgment, it is right to work for his values and to keep the product for his work. If life on earth is his purpose, he has a right to live as a rational being: nature forbids him the irrational — Ayn Rand

The biggest danger to American stability," Johnson argued, "is the politics of principle, which brings out the masses in irrational fights for unlimited goals, for once the masses begin to move, then the whole thing begins to explode. Thus it is for the sake of nothing less than stability that I consider myself a consensus man. — Doris Kearns Goodwin

Black(people) hold onto their God just as the drunken man holds on to the street lamp post - for physical support only. — Tai Solarin

Quick, I told myself. Try to remember what you learned from Jimbo's Self Defence for Young Ladies. Jimbo was a beefy man with prison tats.
"Go into the nearest dark alley," I recalled Jimbo saying. "Freeze like a rabbit or the creature you desire your attacker to mistake you for. If your attacker shouts out to you, respond politely - maybe your optimism will change his mind. If you're about to get into an elevator with a man you feel uncomfortable spending time with in a small, escapeless room, head right in. Remember , fear i an irrational emotion, you should probably ignore it."
Armed with these tips, I hung a right into the nearest dead-end, curled into a ball and started rolling. — The Harvard Lampoon

If man is reduced to being nothing but a character in history, he has no other choice but to subside into the sound and fury of acompletely irrational history or to endow history with the form of human reason. — Albert Camus

There must occur a time in every man's life when the idea of a sudden, irrational death does not frighten him. This shall suffice to cure a lot of his persistent miseries. — Ashfaq Saraf

I say this because as an older man I am prone to ponder matters in the light of death in a way that you are not. I am like a traveler from Mars who looks down in astonishment at what passes here. And what I see is the same human frailty passed from generation to generation. What I see is again and again the same sad human frailty. We hate one another; we are the victims of irrational fears. And there is nothing in the stream of human history to suggest we are going to change this. But
I digress, confess that. I merely wish to point out that in the face of such a world you have only yourselves to rely on. You have only the decision you must make, each of you, alone. And will you contribute to the indifferent forces that ceaselessly conspire toward injustice? Or will you stand up against this endless tide and in the face of it be truly human? — David Guterson

Racism is not simply about one man's irrational hatred of another but his self-hatred, doubting his own moral goodness and purpose. — Michael R. French

The man who is thus outside the confines of every value-combination, and has become the exclusive representative of an individual value, is metaphysically an outcast, for his autonomy presupposes the resolution and disintegration of all system into its individual elements; such a man is liberated from values and from style, and can be influenced only by the irrational. — Hermann Broch

Man isn't a noble savage, he's an ignoble savage. He is irrational, brutal, weak, silly, unable to be objective about anything where his own interests are involved-that about sums it up. I'm interested in the brutal and violent nature of man because it's a true picture of him. And any attempt to create social institutions on a false view of the nature of man is probably doomed to failure. — Stanley Kubrick

Baldwin had never grasped the concept of atonement. His view of Matthew's faith was purely transactional - you went to church, confessed, and walked out a clean man. But salvation was more complicated. Philippe had come to understand that in the end, although he had long found Matthew's constant search for forgiveness irritating and irrational. — Deborah Harkness

It is also the irrational instinct of religionism, the vague yearning for something to worship - a reflection or shadow of the true devotional principle - which prompts men to project a subjective image of the lower, personal mind, and to endow it with human attributes, and then to claim to receive "revelations" from it; and this - the image of the Beast, or unspiritual mind, - is their anthropomorphic God, a fabulous monster the worship of which has ever prompted men to fanaticism and persecution, and has inflicted untold misery and dread upon the masses of mankind, as well as physical torture and death in hideous forms upon the many martyrs who have refused to bend the knee to this Gorgonean phantom of the beast-mind of man. Truly, where the worshipers of this image of the Beast predominate, the man whose brow and hand are unbranded by this superstition, who neither thinks nor acts in accordance with it, suffers ostracism if not virulent persecution. — James Morgan Pryse

For the modern economist this is very difficult to understand. He is used to measuring the "standard of living" by the amount of annual consumption, assuming all the time that a man who consumes more is "better off" than a man who consumes less. A Buddhist economist would consider this approach excessively irrational: since consumption is merely a means to human well-being, the aim should be to obtain the maximum of well-being with the minimum of consumption. Thus, if the purpose of clothing is a certain amount of temperature comfort and an attractive appearance, the task is to attain this purpose with the smallest possible effort, that is, with the smallest annual destruction of cloth and with the help of designs that involve the smallest possible input of toil. The less toil there is, the more time and strength is left for artistic creativity. — E.F. Schumacher

Bin Laden does reprehensible activities, and we should surely take care of that by killing him as soon as we can. But he's not an irrational man. He's a very worthy enemy. He's an enemy to worry about. — Michael Scheuer

While the Right of Suffrage is conceded to thousands notoriously ignorant, vicious, and drunken, ... a Constitutional denial to Black men, as such, of Political Rights freely secured to White men, is monstrously unjust and irrational. — Horace Greeley

I understand and sympathize with the reasonable needs of a reasonable number of people on a finite continent. All life depends upon other life. But what is happening today, in North America, is not rational use but irrational massacre. Man the Pest, multiplied to the swarming stage, is attacking the remaining forests like a plague of locusts on a field of grain. — Edward Abbey

Since the Greeks, Western man has believed that Being, all Being, is intelligible, that there is a reason for everythingand that the cosmos is, finally, intelligible. The Oriental, on the other hand, has accepted his existence within a universe that would appear to be meaningless, to the rational Western mind, and has lived with this meaninglessness. Hence the artistic form that seems natural to the Oriental is one that is just as formless or formal, as irrational, as life itself. — William Barrett

So far has Western society departed from the ancient taboos against murder, theft, and rape that we are now faced with juvenile delinquents who have no inner check against wantonly assaulting other human beings at random 'for kicks' while we have adult delinquents capable of deliberately planning the extermination of tens of millions of human beings, in carrying out, also doubtless for kicks, a mathematical theory of games. Today our civilization is relapsing into a state far more primitive, far more irrational, than any taboo-ridden society now known-for lack of any effective taboos. If Western man could establish an inviolate taboo against random extermination, our society would enjoy a far more effective safeguard against both private violence and still impending collective nuclear horrors than the United Nations or the fallible mechanisms of Fail-Safe. — Lewis Mumford

Nurses on transplant wards often remarked that male transplant patients show renewed interest in sex. One reported that a patient asked her to wear something other than "that shapeless scrub" so he could see her breasts. A post-op who had been impotent for seven years before the operation was found holding his penis and demonstrating an erection. Another nurse spoke of a man who left the fly of his pajamas unfastened to show her his penis. Conclude Tabler and Frierson, "this irrational but common belief that the recipient will somehow develop characteristics of the donor is generally transitory but may alter sexual patterns.' Let us hope that the man with the chicken heart was blessed with a patient and open-minded spouse. — Mary Roach

It is not man who is the enemy of the human species. It is the irrational; it is the spiritual when it is divorced from the material; from the lesson in one beating heart or one bleeding vein. — Anne Rice

Man: an irrational being who imagines himself to be a rational one. — Marty Rubin

Animals never have recourse to law courts, because they have no will to love; but man, having reason, feels the need of justifying his irrational behavior when he does wrong. — Fulton J. Sheen

Overcrowding in the cities is producing a collective madness in which irrational violence flourishes because man needs more space in which to be than the modern city allows. — Gore Vidal

He has the capacity to veer with every wind, or, stubbornly, to insert himself into some fantastically elaborated and irrational social institution only to perish with it. [For man is a] fickle, erratic, dangerous creature [whose] restless mind would try all paths, all horrors, all betrayals ... believe all things and believe nothing ... kill for shadowy ideas more ferociously than other creatures kill for food, then, in a generation or less, forget what bloody dream had so oppressed him — Loren Eiseley

A woman is sometimes fugitive, irrational, indeterminable, illogical and contradictory. A great deal of forbearance ought to be shown her, and a good deal of prudence exercised with regard to her, for she may bring about innumerable evils without knowing it. Capable of all kinds of devotion, and of all kinds of treason, monster incomprehensible, raised to the second power, she is at once the delight and the terror of man. — Henri Frederic Amiel

His kiss was brutal, punishing, for making him feel like this. He was
desperate. Out of control. Never had he experienced this kind of irrational
urgency. He needed her. Like a starving man needed food. Like a dying man
needed salvation. Now. Before everything went to hell. Before she could change her mind. — Monica McCarty

To deprecate human reason by saying that none of us is or can be omniscient is absurd, for it takes an impossible standard as the judge of a possible and real condition. All of our knowledge we get from the exercise of our reason; to say that no man can be God and know everything is to take an irrational standard of evaluation. — Murray Rothbard

Such terrifying powers we possess, but what a sorry lot of gods some men are. And the worst of it is not the cruelty but the arrogance, the sheer hubris of those who bring only violence and fear into the animal world, as if it needed any more of either. Their lives entail enough frights and tribulations without the modern fire-makers, now armed with perfected, inescapable weapons, traipsing along for more fun and thrills at their expense even as so many of them die away. It is our fellow creatures' lot in the universe, the place assigned them in creation, to be completely at our mercy, the fiercest wolf or tiger defenseless against the most cowardly man. And to me it has always seemed not only ungenerous and shabby but a kind of supreme snobbery to deal cavalierly with them, as if their little share of the earth's happiness and grief were inconsequential, meaningless, beneath a man's attention, trumped by any and all designs he might have on them, however base, irrational, or wicked. — Matthew Scully

I thought of the fate of Descartes' famous formulation: man as 'master and proprietor of nature.' Having brought off miracles in science and technology, this 'master and proprietor' is suddenly realizing that he owns nothing and is master neither of nature (it is vanishing, little by little, from the planet), nor of History (it has escaped him), nor of himself (he is led by the irrational forces of his soul). But if God is gone and man is no longer master, then who is master? The planet is moving through the void without any master. There it is, the unbearable lightness of being. — Milan Kundera

Be free from grief not through insensibility like the irrational animals, nor through want of thought like the foolish, but like a man of virtue by having reason as the consolation of grief. — Epictetus

To the extent to which a man is rational, life is the premise directing his actions. To the extent to which he is irrational, the premise directing his actions is death. — Ayn Rand

Can this be in human nature! - Can such horrible perversion of right be permitted! Can man, who calls himself endowed with reason, and immeasurably superior to every other created being, argue himself into the commission of such horrible folly, such inveterate cruelty, as exceeds all the acts of the most irrational and ferocious brute. Brutes do not deliberately slaughter their species; it remains for man only, man, proud of his prerogative of reason, and boasting of his sense of justice, to unite the most terrible extremes of folly and wickedness! — Ann Radcliffe

[T]he only real moral crime that one man can commit against another is the attempt to create, by his words or actions, an impression of the contradictory, the impossible, the irrational, and thus shake the concept of rationality in his victim. — Ayn Rand

This was a man who'd fought long and hard to keep me, even when I was bent on self-destructing us. This was a man who understood I could be difficult and stubborn and a little bit irrational (okay, maybe a freaking lot irrational), and still loved me. — Samantha Young

In Gnosticism, man belongs with God against the world and the creator of the world (both of which are crazy, whether they realize it or not). The answer to Fat's question, "Is the universe irrational, and is it irrational because an irrational mind governs it?" receives this answer, via Dr. Stone: "Yes it is, the universe is irrational; the mind governing it is irrational; but above them lies another God, the true God, and he is not irrational; in addition that true God has outwitted the powers of this world, ventured here to help us, and we know him as the Logos," which, according to Fat, is living information. — Philip K. Dick

There are ages in which the rational man and the intuitive man stand side by side, the one in fear of intuition, the other with scorn for abstraction. The latter is just as irrational as the former is inartistic. — Friedrich Nietzsche
