Life, individual or collective, personal or historic, is the one entity in the universe whose substance is compact of danger, of adventure. It is, in the strict sense of the word, drama. ... The primary, radical meaning of life appears when it is employed in the sense not of biology, but of biography. For the very strong reason that the whole of biology is quite definitely only a chapter in certain biographies, it is what biologists do in the portion of their lives open to biography.

And why should man, added he, pretend to an exemption from the lot of all other animals? The whole earth, believe me, PHILO, is cursed and polluted. A perpetual war is kindled amongst all living creatures. Necessity, hunger, want, stimulate the strong and courageous: Fear, anxiety, terror, agitate the weak and infirm. The first entrance into life gives anguish to the new-born infant and to its wretched parent: Weakness, impotence, distress, attend each stage of that life: and it is at last finished in agony and horror.

Man has an invincible inclination to allow himself to be deceived and is, as it were, enchanted with happiness when the rhapsodist tells him epic fables as if they were true, or when the actor in the theater acts more royally than any real king. So long as it is able to deceive without injuring, that master of deception, the intellect, is free; it is released from its former slavery and celebrates its Saturnalia. It is never more luxuriant, richer, prouder, more clever and more daring.

The most obvious division of society is into rich and poor; and it is no less obvious, that the number of the former bear a great disproportion to those of the latter. The whole business of the poor is to administer to the idleness, folly, and luxury of the rich; and that of the rich, in return, is to find the best methods of confirming the slavery and increasing the burdens of the poor. In a state of nature, it is an invariable law, that a man's acquisitions are in proportion to his labours. In a state of artificial society, it is a law as constant and as invariable, that those who labour most enjoy the fewest things; and that those who labour not at all have the greatest number of enjoyments. A constitution of things this, strange and ridiculous beyond expression! We scarce believe a thing when we are told it, which we actually see before our eyes every day without being in the least surprised.

Christianity taught only what the whole of Asia knew already long before and even better.

The man who is fortunate in his choice of son-in-law gains a son; the man unfortunate in his choice loses his daughter also.

It is perhaps not a surprise that photography developed as a technological medium in the industrial age, when reality started to disappear. It is even perhaps the disappearance of reality that triggered this technical form. Reality found a way to mutate into an image.

The bourgeoisie hides the fact that it is the bourgeoisie and thereby produces myth; revolution announces itself openly as revolution and thereby abolishes myth.

It is a waste of energy to be angry with a man who behaves badly, just as it is to be angry with a car that won't go. The difference is that you can compel your car to go to a garage, but you cannot compel Hitler to go to a psychiatrist.

Create all the happiness you are able to create: remove all the misery you are able to remove. Every day will allow you to add something to the pleasure of others, or to diminish something of their pains. And for every grain of enjoyment you sow in the bosom of another, you shall find a harvest in your own bosom; while every sorrow which you pluck out from the thoughts and feelings of a fellow creature shall be replaced by beautiful peace and joy in the sanctuary of your soul.

When some one boasted that at the Pythian games he had vanquished men, Diogenes replied, "Nay, I defeat men, you defeat slaves."

Fame and tranquility can never be bedfellows.

Man flows at once to God when the channel of purity is open.

By quarrelling amongst themselves, instead of confederating, Germans and Scandinavians, both of them belonging to the same great race, only prepare the way for their hereditary enemy, the Slav. 

Global rationality, the rationality of neoclassical theory, assumes that the decision maker has a comprehensive, consistent utility function, knows all the alternatives that are available for choice, can compute the expected value of utility associated with each alternative, and chooses the alternative that maximizes expected utility. Bounded rationality, a rationality that is consistent with our knowledge of actual human choice behavior, assumes that the decision maker must search for alternatives, has egregiously incomplete and inaccurate knowledge about the consequences of actions, and chooses actions that are expected to be satisfactory (attain targets while satisfying constraints).

At least two thirds of our miseries spring from human stupidity, human malice, and those great motivators and justifiers of malice and stupidity, idealism, dogmatism and proselytizing zeal on behalf of religious or political idols.

If by motivation we mean whatever it is that causes someone to follow a particular course of action, then every action is motivated - by definition. But in most human behavior the relation between motives and action is not simple; it is mediated by a whole chain of events and surrounding conditions. We observe a man scratching his arm. His motive (or goal)? To relieve an itch.

Those who purge the soul believe that the soul can receive no benefit from any teachings offered to it until someone by cross-questioning reduces him who is cross-questioned to an attitude of modesty, by removing the opinions that obstruct the teachings, and thus purges him and makes him think that he knows only what he knows, and no more.

I doubt not but one great reason why many children abandon themselves wholly to silly sports, and trifle away all their time insipidly, is, because they have found their curiosity baulk'd, and their inquiries neglected. But had they been treated with more kindness and respect, and their questions answered, as they should, to their satisfaction; I doubt not but that they would have taken more pleasure in learning, and improving their knowledge, wherein there would still be newness and variety, which is what they are delighted with, than in returning over and over to the same play and play-things.

The point, as Marx saw it, is that dreams never come true.

The soldier is applauded who refuses to serve in an unjust war by those who do not refuse to sustain the unjust government which makes the war; is applauded by those whose own act and authority he disregards and sets at naught; as if the state were penitent to that degree that it hired one to scourge it while it sinned, but not to that degree that it left off sinning for a moment.

The good King of France desires only that you would take his word and let him be quiet till he has got the West Indies into his hands and his grandson well established in Spain, and then you may be sure you shall be as safe as he will let you be in your religion, property and trade, to all which who can be such an infidel as not to believe him a great friend?

Knowing whether or not one can live without appeal is all that interests me.

Our bodies are perishable, wealth is not at all permanent and death is always nearby. Therefore we must immediately engage in acts of merit.

Not content with real sufferings, the anxious man imposes imaginary ones on himself; he is a being for whom unreality exists, must exist; otherwise where would he obtain the ration of torment his nature demands?

It would be wrong to suppose that the man of any particular period always looks upon past times as below the level of his own, simply because they are past. It is enough to recall that to the seeming of Jorge Manrique, "Any time gone by was better."... From A.D. 150 on, this impression of a shrinking of vitality, of a falling from position, of decay and loss of pulse shows itself increasingly in the Roman Empire. Had not Horace already sung: "Our fathers, viler than our grandfathers, begot us who are even viler, and we shall bring forth a progeny more degenerate still"?

One can only become a philosopher, but not be one. As one believes he is a philosopher, he stops being one.

It would be too ridiculous to go about seriously to prove that wealth does not consist in money, or in gold and silver; but in what money purchases, and is valuable only for purchasing. Money no doubt, makes always a part of the national capital; but it has already been shown that it generally makes but a small part, and always the most unprofitable part of it.

On this showing, the nature of the breakdowns of civilizations can be summed up in three points: a failure of creative power in the minority, an answering withdrawal of mimesis on the part of the majority, and a consequent loss of social unity in the society as a whole.

The criminal law has, from the point of view of thwarted virtue, the merit of allowing an outlet for those impulses of aggression which cowardice, disguised as morality, restrains in their more spontaneous forms. War has the same merit. You must not kill you neighbor, whom perhaps you genuinely hate, but by a little propaganda this hate can be transferred to some foreign nation, against whom all your murderous impulses become patriotic heroism.

Among the celestial bodies that are revolving over our heads, though the motions are not the same, and though the force is not equal, yet they move, and ever have moved, without clashing, and in perfect harmony.

One should attend to one's enemies, for they are the first persons to detect one's errors.

The utilitarian morality does recognise in human beings the power of sacrificing their own greatest good for the good of others. It only refuses to admit that the sacrifice is itself a good. A sacrifice which does not increase, or tend to increase, the sum total of happiness, it considers as wasted. The only self-renunciation which it applauds, is devotion to the happiness, or to some of the means of happiness, of others; either of mankind collectively, or of individuals within the limits imposed by the collective interests of mankind.

... no testimony is sufficient to establish a miracle, unless the testimony be of such a kind, that its falsehood would be more miraculous, than the fact, which it endeavors to establish.

The disparagement of empirical evidence in favor of a metaphysical world of illusion has its origin in the conflict between the emancipated individual of bourgeois society and his fate within that society.

This in turn suggests an answer to our question: what happened between the birth of De Sade and the birth of Krafft-Ebbing? The rise of the novel taught Europe to use its imagination. And when imagination was applied to sex, the result was the rise of pornography -- and of "sexual perversion."

Without its assiduity to the ridiculous, would the human race have lasted more than a single generation?

Between God and man there is and remains an eternal, essential, qualitative difference. The paradoxical relationship (which, quite rightly, cannot be thought, but only believed) appears when God appoints a particular man to divine authority, in relation, be it carefully noted, to that which has entrusted to him.

Better to be an animal than a man, an insect than an animal, a plant than an insect, and so on. Salvation? Whatever diminishes the kingdom of consciousness and compromises its supremacy.

"Here is the chalk." This is a truth; and here and the now hereby characterize the chalk so that we emphasize by saying; the chalk, which means "this." We take a scrap of paper and we write the truth down: "Here is the chalk." We lay this written statement beside the thing of which it is the truth. After the lecture is finished both doors are opened, the classroom is aired, there will be a draft, and the scrap of paper, let us suppose, will flutter out into the corridor. A student finds it on his way to the cafeteria, reads the sentence. "Here is the chalk," and ascertains that this is not true at all. Through the draft the truth has become an untruth. Strange that a truth should depend on a gust of wind. ... We have made the truth about the chalk independent of us and entrusted it to a scrap of paper.

Genius is always sufficiently the enemy of genius by over influence.

Fascism is not defined by the number of its victims, but by the way it kills them.

That Man is the product of causes that had no prevision of the end they were achieving; that his origin, his growth, his hopes and fears, his loves and his beliefs, are but the outcome of accidental collocations of atoms; that no fire, no heroism, no intensity of thought and feeling, can preserve individual life beyond the grave; that all the labors of the ages, all the devotion, all the inspiration, all the noonday brightness of human genius, are destined to extinction in the vast death of the solar system, and that the whole temple of Man's achievement must inevitably be buried beneath the debris of a universe in ruins - all these things, if not quite beyond dispute, are yet so nearly certain that no philosophy which rejects them can hope to stand. Only within the scaffolding of these truths, only on the firm foundation of unyielding despair, can the soul's habitation henceforth be safely built.

Everyone who has left houses or brothers or sisters or father or mother or children or fields for my sake will receive a hundred times as much and will inherit eternal life.

Every tax, however, is to the person who pays it a badge, not of slavery but of liberty. It denotes that he is a subject to government, indeed, but that, as he has some property, he cannot himself be the property of a master.

Neither a man nor a crowd nor a nation can be trusted to act humanely or to think sanely under the influence of a great fear.

The first characteristic of the human species is man's ability, as a rational being, to establish character for himself, as well as for the society into which nature has placed him. This ability, however, presupposes an already favorable natural predisposition and an inclination to the good in man, because the evil is really without character (since it is at odds with itself, and since it does not tolerate any lasting principle within itself)

If countries were named after the words you first hear when you go there, England would have to be called Damn It.

Anything can be made to look good or bad by being redescribed.
