In a world, man must create his own essence: it is in throwing himself into the world, suffering there, struggling there, that he gradually defines himself.

This is that which I think great readers are apt to be mistaken in; those who have read of everything, are thought to understand everything too; but it is not always so. Reading furnishes the mind only with materials of knowledge; it is thinking that makes what we read ours. We are of the ruminating kind, and it is not enough to cram ourselves with a great load of collections ; unless we chew them over again, they will not give us strength and nourishment.

In the old system, the body of the condemned man became the king's property, on which the sovereign left his mark and brought down the effects of his power. Now he will be rather the property of society, the object of a collective and useful appropriation.

What is there in 'Paradise Lost' to elevate and astonish like Herschel or Somerville?

We are spinning our own fates, good or evil, and never to be undone. Every smallest stroke of virtue or of vice leaves its never so little scar. ...Nothing we ever do is, in strict scientific literalness, wiped out.

The real field of knowledge is not the given fact about things as they are, but the critical evaluation of them as a prelude to passing beyond their given form. Knowledge deals with appearances in order to get beyond them. .... The concept of reality has thus turned into the concept of possibility. The real is not yet 'actual,' but is at first only the possibility of an actual.

The irony of world history turns everything upside down. We, the "revolutionaries," the "rebels"-we are thriving far better on legal methods than on illegal methods and revolt. The parties of order, as they call themselves, are perishing under the legal conditions created by themselves. They cry despairingly with Odilon Barrot: la légalité notes tue, legality is the death of us; whereas we, under this legality, get firm muscles and rosy cheeks and look like eternal life.

An intellectual is a person who has discovered something more interesting than sex.

Poetry - No definition of poetry is adequate unless it be poetry itself. The most accurate analysis by the rarest wisdom is yet insufficient, and the poet will instantly prove it false by setting aside its requisitions. It is indeed all that we do not know. The poet does not need to see how meadows are something else than earth, grass, and water, but how they are thus much. He does not need discover that potato blows are as beautiful as violets, as the farmer thinks, but only how good potato blows are. The poem is drawn out from under the feet of the poet, his whole weight has rested on this ground. It has a logic more severe than the logician's. You might as well think to go in pursuit of the rainbow, and embrace it on the next hill, as to embrace the whole of poetry even in thought.

And I myself, in Rome, heard it said openly in the streets, "If there is a hell, then Rome is built on it." That is, "After the devil himself, there is no worse folk than the pope and his followers."

Life is bristling with thorns, and I know no other remedy than to cultivate one's garden.

When the rich make war, it's the poor that die.

Whenever convictions are not arrived at by direct contact with the world and the objects themselves, but indirectly through a critique of the opinions of others, the processes of thinking are impregnated with ressentiment. The establishment of "criteria" for testing the correctness of opinions then becomes the most important task. Genuine and fruitful criticism judges all opinions with reference to the object itself. Ressentiment criticism, on the contrary, accepts no "object" that has not stood the test of criticism.

No man is free who is not master of himself.

What is to prevent one from telling truth as he laughs, even as teachers sometimes give cookies to children to coax them into learning their A B C?

It is necessary to insist upon this extraordinary but undeniable fact: experimental science has progressed thanks in great part to the work of men astoundingly mediocre, and even less than mediocre. That is to say, modern science, the root and symbol of our actual civilization, finds a place for the intellectually commonplace man and allows him to work therein with success.

Intellect is invisible to the man who has none.

If you punish a child for being naughty, and reward him for being good, he will do right merely for the sake of the reward; and when he goes out into the world and finds that goodness is not always rewarded, nor wickedness always punished, he will grow into a man who only thinks about how he may get on in the world, and does right or wrong according as he finds either of advantage to himself.

We boil at different degrees.

Reading the Socratic dialogues one has the feeling: what a frightful waste of time! What's the point of these arguments that prove nothing and clarify nothing?

Equally there is no rhythm when variations are not placed. There is a wealth of suggestions in the phrase "takes place". The change not only comes but it belongs; it had its definite place in a larger whole.

The will is the living principle of the rational soul, is indeed itself reason, when purely and simply apprehended. That reason is itself active, means, that the pure will, as such, rules and is effectual. The infinite reason alone lies immediately and entirely in the purely spiritual order. The finite being lives necessarily at the same time in a sensuous order; that is to say, in one which presents to him other objects than those of pure reason; a material object, to be advanced by instruments and powers, standing indeed under the immediate command of the will, but whose efficacy is conditional also on its own natural laws.

The tangible source of exploitation disappears behind the façade of objective rationality.

Plato was synthesis of Europe and Asia, and a decidedly Oriental element pervades his philosophy, giving it a sunrise color.

In the beginning there were two primal spirits,Twins spontaneously active,These are the Good and the Evil, in thought, and in word, and in deed.

The capabilities (intellectual and material) of contemporary society are immeasurably greater than ever before-which means that the scope of society's domination over the individual is immeasurably greater than ever before. Our society distinguishes itself by conquering the centrifugal social forces with Technology rather than Terror, on the dual basis of an overwhelming efficiency and an increasing standard of living.

In this frame of mind it occurred to me to put the question directly to myself: "Suppose that all your objects in life were realized; that all the changes in institutions and opinions which you are looking forward to, could be completely effected at this very instant: would this be a great joy and happiness to you?" And an irrepressible self-consciousness distinctly answered, "No!" At this my heart sank within me: the whole foundation on which my life was constructed fell down. All my happiness was to have been found in the continual pursuit of this end. The end had ceased to charm, and how could there ever again be any interest in the means? I seemed to have nothing left to live for.

God ... desires His creature to be able to oppose Him. He has given that creature freedom. ... When man turns away from evil with that whole measure of power with which he is able to rebel against God, then he has truly turned to God.

The unassisted hand and the understanding left to itself possess but little power. Effects are produced by the means of instruments and helps, which the understanding requires no less than the hand; and as instruments either promote or regulate the motion of the hand, so those that are applied to the mind prompt or protect the understanding.

The woman is increasingly aware that love alone can give her full stature, just as the man begins to discern that spirit alone can endow his life with its highest meaning. Fundamentally, therefore, both seek a psychic relation to the other, because love needs the spirit, and the spirit love, for their fulfillment.

An avidity to punish is always dangerous to liberty. It leads men to stretch, to misinterpret, and to misapply even the best of laws. He that would make his own liberty secure must guard even his enemy from oppression; for if he violates this duty he establishes a precedent that will reach to himself.

Love, a tacit agreement between two unhappy parties to overestimate each other. p. 111, first American edition

Gaiety - a quality of ordinary men. Genius always presupposes some disorder in the machine.

If I were asked to summarize as briefly as possible my vision of things, to reduce it to its most succinct expression, I should replace words with an exclamation point, a definitive !

... the attempt to make heaven on earth invariably produces hell. It leads to intolerance. It leads to religious wars, and to the saving of souls through the inquisition. And it is, I believe, based on a complete misunderstanding of our moral duties. It is our duty to help those who need help; but it cannot be our duty to make others happy, since this does not depend on us, and since it would only too often mean intruding on the privacy of those towards whom we have such amiable intentions.

Modern man may assert that he can dispense with them, and he may bolster his opinion by insisting that there is no scientific evidence of their truth. But since we are dealing with invisible and unknowable things (for God is beyond human understanding, and there is no mean of proving immortality), why should we bother with evidence?

The Ideal Man of the eighteenth century was the Rationalist; of the seventeenth, the Christian Stoic; of the Renaissance, the Free Individual; of the Middle Ages, the Contemplative Saint. And what is our Ideal Man? On what grand and luminous mythological figure does contemporary humanity attempt to model itself? The question is embarrassing. Nobody knows. And, in spite of all the laudable efforts of the Institute for Intellectual Co-operation to fabricate an acceptable Ideal Man for the use of Ministers of Education, nobody, I suspect, will know until such time as a major poet appears upon the scene with the unmistakable revelation. Meanwhile, one must be content to go on piping up for reason and realism and a certain decency.

If there is one realm in which it is essential to be sublime, it is in wickedness. You spit on a petty thief, but you can't deny a kind of respect for the great criminal.

The abolition of private property has become not only possible but absolutely necessary. ... The outcome can only be the victory of the proletariat.

We invite this Congress, and through it the scientists of the world and the general public, to subscribe to the following resolution: "In view of the fact that in any future world war nuclear weapons will certainly be employed, and that such weapons threaten the continued existence of mankind, we urge the governments of the world to realize, and to acknowledge publicly, that their purpose cannot be furthered by a world war, and we urge them, consequently, to find peaceful means for the settlement of all matters of dispute between them".

You must always be puzzled by mental illness. The thing I would dread most, if I became mentally ill, would be your adopting a common sense attitude; that you could take it for granted that I was deluded.

In my education, as in that of everyone, the moral influences, which are so much more important than all others, are also the most complicated, and the most difficult to specify with any approach to completeness.

Faith is not in power but in truth.

Whenever government assumes to deliver us from the trouble of thinking for ourselves, the only consequences it produces are those of torpor and imbecility.

All that time is lost which might be better employed.

He who can buy bravery is brace, though a coward. As money is not exchanged for anyone specific quality, for any one specific thing, or for any particular human essential power, but for the entire objective world of man and nature, from the standpoint of its possessor it therefore serves to exchange every property for every other, even contradictory, property and object: it is the fraternization of impossibilities. It makes contradictions embrace.

The obliteration of the evil hath been practised by two means, some kind of redemption or expiation of that which is past, and an inception or account de novo for the time to come. But this part seemeth sacred and religious, and justly; for all good moral philosophy (as was said) is but a handmaid to religion.
