From the power to transform him into a thing by killing him there proceeds another power, and much more prodigious, that which makes a thing of him while he still lives.

I know of no country in which there is so little independence of mind and real freedom of discussion as in America.

A special kind of beauty exists which is born in language, of language, and for language.

Several excuses are always less convincing than one.

This art is music. It stands quite apart from all the others. In it we do not recognize the copy, the repetition, of any Idea of the inner nature of the world. Yet it is such a great and exceedingly fine art, its effect on man's innermost nature is so powerful, and it is so completely and profoundly understood by him in his innermost being as an entirely universal language, whose distinctness surpasses even that of the world of perception itself, that in it we certainly have to look for more than that.

Mathematics takes us still further from what is human, into the region of absolute necessity, to which not only the world, but every possible world, must conform.

The beginning in every task is the chief thing.

So far as it has gone, it probably is the most pure and defecated publick good which ever has been conferred on mankind.

I have said more than once, that I hold space to be something purely relative, as time; an order of coexistences, as time is an order of successions.

At puberty, the elements of an unsuperstitious sexual morality ought to be taught. Boys and girls should be taught that nothing can justify sexual intercourse unless there is mutual inclination... Boys and girls should be taught respect for each other's liberty; they should be made to feel that nothing gives one human being rights over another, and that jealousy and possessiveness kill love. They should be taught that to bring another human being into the world is a very serious matter, only to be undertaken when the child will have a reasonable prospect of health, good surroundings, and parental care. But they should also be taught methods of birth control, so as to insure that children shall only come when they are wanted. Finally, they should be taught the dangers of venereal disease, and the methods of prevention and cure. The increase of human happiness to be expected from sex education on these lines is immeasurable.

The world is chaos. Nothingness is the yet-to-be-born god of the world.

Eat not the heart.

Christianity is most admirably adapted to the training of slaves, to the perpetuation of a slave society; in short, to the very conditions confronting us to-day.... The rulers of the earth have realized long ago what potent poison inheres in the Christian religion. That is the reason they foster it; that is why they leave nothing undone to instill it into the blood of the people. They know only too well that the subtleness of the Christian teachings is a more powerful protection against rebellion and discontent than the club or the gun.

I cannot escape the objection that there is no state of mind, however simple, that does not change every moment.

We get into the habit of living before acquiring the habit of thinking.

Let us apply these principles to adultery. The state can no more prohibit it or punish it by law than any other illegitimate satisfaction of the sexual impulse.

The real discovery is the one which enables me to stop doing philosophy when I want to. The one that gives philosophy peace, so that it is no longer tormented by questions which bring itself into question.

There's something about a pious man such as he. He will cheerfully cut your throat if it suits him, but he will hesitate to endanger the welfare of your immaterial and problematical soul.

Every book is a quotation; and every house is a quotation out of all forests and mines and stone-quarries; and every man is a quotation from all his ancestors.

Communism differs from all previous movements in that it overturns the basis of all earlier relations of production and intercourse, and for the first time consciously treats all natural premises as the creatures of hitherto existing men, strips them of their natural character and subjugates them to the power of the united individuals. Its organisation is, therefore, essentially economic, the material production of the conditions of this unity; it turns existing conditions into conditions of unity. The reality, which communism is creating, is precisely the true basis for rendering it impossible that anything should exist independently of individuals, insofar as reality is only a product of the preceding intercourse of individuals themselves.

I see not the shadow of a reason to conclude that their [the sexes'] virtues should differ in respect to their nature. In fact, how can they, if virtue has only one eternal standard? I must therefore, if I reason consequentially, as strenuously maintain that they must have the same simple direction as that there is a God.

Now the basic impulse behind existentialism is optimistic, very much like the impulse behind all science. Existentialism is romanticism, and romanticism is the feeling that man is not the mere he has always taken himself for. Romanticism began as a tremendous surge of optimism about the stature of man. Its aim - like that of science - was to raise man above the muddled feelings and impulses of his everyday humanity, and to make him a god-like observer of human existence.

I believe that man is the product of natural evolution that is born from the conflict of being a prisoner and separated from nature, and from the need to find unity and harmony with it.

He was genuinely incapable of uttering a single sentence that was not a cliché. Eichmann, despite his rather bad memory, repeated word for word the same stock phrases and self-invented clichés (when he did succeed in constructing a sentence of his own, he repeated it until it became a cliché) each time he referred to an incident or event of importance to him. The longer one listened to him, the more obvious it became that his inability to speak was closely connected with an inability to think, namely to think from the standpoint of somebody else. No communication was possible with him, not because he lied but because he was surrounded by the most reliable of all safeguards against the words and the presence of others, and hence against reality as such.

The Scientific discourse extracts truths from the errors which surround and oppose it on all sides and in every form; and, by demolition of these opposing views as error, and as impossible to true thought, shows the truth as that which alone remains after their withdrawal, and therefore as the only possible truth:--and in this separation of opposites, and elucidation of the truth from the confused chaos in which truth and error lie mingled together, consists the peculiar and characteristic nature of the Scientific discourse. This method creates and produces truth, before our eyes, out of a world full of error.

As the animus is partial to argument, he can best be seen at work in disputes where both parties know they are right. Men can argue in a very womanish way, too, when they are anima-possessed and have thus been transformed into the animus of their own anima.

In obedience to the feeling of reality, we shall insist that, in the analysis of propositions, nothing "unreal" is to be admitted. But, after all, if there is nothing unreal, how, it may be asked, could we admit anything unreal? The reply is that, in dealing with propositions, we are dealing in the first instance with symbols, and if we attribute significance to groups of symbols which have no significance, we shall fall into the error of admitting unrealities, in the only sense in which this is possible, namely, as objects described.

A philosopher is a man who has to cure many intellectual diseases in himself before he can arrive at the notions of common sense.

An increase in the productivity of labour means nothing more than that the same capital creates the same value with less labour, or that less labour creates the same product with more capital.

There is no such thing as data-driven thinking.

By convention sweet is sweet, bitter is bitter, hot is hot, cold is cold, color is color; but in truth there are only atoms and the void.

Nature paints the best part of a picture, carves the best parts of the statue, builds the best part of the house, and speaks the best part of the oration.

The supreme effort of the avant-guard is onward, ever onward.

In our reasonings concerning matter of fact, there are all imaginable degrees of assurance, from the highest certainty to the lowest species of moral evidence. A wise man, therefore, proportions his belief to the evidence.

Woe unto you, lawyers! for ye have taken away the key of knowledge: ye entered not in yourselves, and them that were entering in ye hindered. And as he said these things unto them, the scribes and the Pharisees began to urge him vehemently, and to provoke him to speak of many things: Laying wait for him, and seeking to catch something out of his mouth, that they might accuse him.

Nearly allied to justice are the virtues of beneficence, compassion, gratitude, piety, and friendship.

My Father is glorified in this, that you keep bearing much fruit and prove yourselves my disciples. Just as the Father has loved me, so I have loved you; remain in my love. If you observe my commandments, you will remain in my love, just as I have observed the commandments of the Father and remain in his love. “These things I have spoken to you, so that my joy may be in you and your joy may be made full. This is my commandment, that you love one another just as I have loved you. No one has love greater than this, that someone should surrender his life in behalf of his friends. You are my friends if you do what I am commanding you. I no longer call you slaves, because a slave does not know what his master does. But I have called you friends, because I have made known to you all the things I have heard from my Father.

Anxiety - or the fanaticism of the worst.

Few are the women and maidens who would let themselves think that one could at the same time be joyous and modest. They are all bold and coarse in their speech, in their demeanor wild and lewd. That is now the fashion of being in good cheer. But it is specially evil that the young maiden folk are exceedingly bold of speech and bearing, and curse like troopers, to say nothing of their shameful words and scandalous coarse sayings, which one always hears and learns from another.

People must be governed in a manner agreeable to their temper and disposition; and men of free character and spirit must be ruled with, at least, some condescension to this spirit and this character.

By capitulating to life, this world has betrayed nothingness. . . . I resign from movement, and from my dreams. Absence! You shall be my sole glory. . . . Let "desire" be forever stricken from the dictionary, and from the soul! I retreat before the dizzying farce of tomorrows. And if I still cling to a few hopes, I have lost forever the faculty of hoping.

Out of love, God becomes man. He says: Here you see what it is to be a human being; but he adds: Take care, for I am also God - blessed is he who takes no offense at me. 

FREEDOM, the realization of freedom: who can deny that this is what today heads the agenda of history? ... Revolutionary propaganda is in its deepest sense the negation of the existing conditions of the State, for, with respect to its innermost nature, it has no other program than the destruction of whatever order prevails at the time.... We must not only act politically, but in our politics act religiously, religiously in the sense of freedom, of which the one true expression is justice and love. Indeed, for us alone, who are called the enemies of the Christian religion, for us alone it is reserved, and even made the highest duty ... really to exercise love, this highest commandment of Christ and this only way to true Christianity. 

One age misunderstands another; and a petty age misunderstands all the others in its own ugly way.

The Theophilanthropists do not call themselves the disciples of such or such a man. They avail themselves of the wise precepts that have been transmitted by writers of all countries and in all ages.

It would be an endless task to trace the variety of meannesses, cares, and sorrows, into which women are plunged by the prevailing opinion that they were created rather to feel than reason, and that all the power they obtain, must be obtained by their charms and weakness.

Friendship is unnecessary, like philosophy, like art, like the universe itself (for God did not need to create). It has no survival value; rather it is one of those things which give value to survival.

Happy is that City that hath a wise man to govern it.

In the dominant Western religious system, the love of God is essentially the same as the belief in God, in God's existence, God's justice, God's love. The love of God is essentially a thought experience. In the Eastern religions and in mysticism, the love of God is an intense feeling experience of oneness, inseparably linked with the expression of this love in every act of living.

When we are young, we take a certain pleasure in our infirmities. They seem so new, so rich! With age, they no longer surprise us, we know them too well. Now, without anything unexpected in them, they do not deserve to be endured.
