The proof of a theory is in its reasoning, not in its sponsorship.

The range of socially permissible and desirable satisfaction is greatly enlarged, but through this satisfaction, the Pleasure Principle is reduced-deprived of the claims which are irreconcilable with the established society. Pleasure, thus adjusted, generates submission.

All is interrelated. Heaven and earth, air and water. All are but one thing; not four, not two and not three, but one. Where they are not together, there is only an incomplete piece.

Until the seventeenth century there was no concept of evidence with which to pose the problem of induction!

But he, with these burthens on him, planned, commenced, and completed, the History of India; and this in the course of about ten years, a shorter time than has been occupied (even by writers who had no other employment) in the production of almost any other historical work of equal bulk, and of anything approaching to the same amount of reading and research. And to this is to be added, that during the whole period, a considerable part of almost every day was employed in the instruction of his children: in the case of one of whom, myself, he exerted an amount of labour, care, and perseverance rarely, if ever, employed for a similar purpose, in endeavouring to give, according to his own conception, the highest order of intellectual education.

I am excluded from the possession of a determined object, not through the will of the other, but only through my own free-will. If I had not excluded myself, I should not be excluded. But I must exclude myself from something in virtue of the Conception of Rights.

Give us grace and strength to forbear and to persevere. Give us courage and gaiety and the quiet mind, spare to us our friends, soften to us our enemies.

What strikes one here above all is the crudely empirical conception of profit derived from the outlook of the ordinary capitalist, which wholly contradicts the better esoteric understanding of Adam Smith.

Those who keep the masses of men in subjection by exercising force and cruelty deprive them at once of two vital foods, liberty and obedience; for it is no longer within the power of such masses to accord their inner consent to the authority to which they are subjected. Those who encourage a state of things in which the hope of gain is the principal motive take away from men their obedience, for consent which is its essence is not something which can be sold.

It is the same: a chosen one is a man whom God's finger crushes against the wall.

I think television has betrayed the meaning of democratic speech, adding visual chaos to the confusion of voices. What role does silence have in all this noise?

Natural inclinations are present in things from God, who moves all things. So it is impossible for the natural inclinations of a species to be toward evil in itself. But there is in all perfect animals a natural inclination toward carnal union. Therefore it is impossible for carnal union to be evil in itself.

Whatever you can lose, you should reckon of no account.

Some of their faults people readily admit, but others not so readily.

So rolling time changes the seasons of things. What was of value, becomes in turn of no worth.

Antisthenes ... said once to a youth from Pontus who was on the point of coming to him to be his pupil, and was asking him what things he wanted, "You want a new book, and a new pen, and a new tablet;"

He felt neither guilt nor distress at the pleasure with which he was now filled by the proximity of this young creature, and when he discovered in himself even physical symptoms of his inclination he did not take fright, but continued cheerfully and serenely to see Nick whenever the ordinary run of his duties suggested it, congratulating himself upon the newly achieved solidity and rational calm of his spiritual life.

The object of preaching is, constantly to remind mankind of what mankind are constantly forgetting; not to supply the defects of human intelligence, but to fortify the feebleness of human resolutions.

I don't like the spirit of socialism - I think freedom is the basis of everything.

A thing is important if anyone think it important.

Persons who feel themselves to be exiles in this world-and what noble mind, from Empedocles down, has not had that feeling?-are mightily inclined to believe themselves citizens of another.

When I was a child, the institution of war, which, by then, had been in existence for perhaps about five thousand years, was still being taken for granted by most people in the World as a normal and acceptable fact of life. One small religious community, the Society of Friends, was at that time singular in condemning war as immoral and in consequently refusing to have any part or lot in war-making.

While imprisoned in the shed Pierre had learned not with his intellect but with his whole being, by life itself, that man is created for happiness, that happiness is within him, in the satisfaction of simple human needs, and that all unhappiness arises not from privation but from superfluity. And now during these last three weeks of the march he had learned still another new, consolatory truth- that nothing in this world is terrible. He had learned that as there is no condition in which man can be happy and entirely free, so there is no condition in which he need be unhappy and lack freedom. He learned that suffering and freedom have their limits and that those limits are very near together....

Tyrants seldom want pretexts.

As to the having and possessing of things, teach them to part with what they have, easily and freely to their friends, and let them find by experience that the most liberal has always the most plenty, with esteem and commendation to boot, and they will quickly learn to practise it.

One cannot demand of a scholar that he show himself a scholar everywhere in society, but the whole tenor of his behavior must none the less betray the thinker, he must always be instructive, his way of judging a thing must even in the smallest matters be such that people can see what it will amount to when, quietly and self-collected, he puts this power to scholarly use.

The endeavor of scientific research to see events in their more general connection in order to determine their laws, is a legitimate and useful occupation. Any protest against such efforts, in the name of freefom from restrictive conditions, would be fruitless if science did not naïvely identify the abstractions called rules and laws with the actually efficacious forces, and confuse the probability that B will follow A with the actual effort make B follow A.

The Hebrews took for their idol, not something made of metal or wood, but a race, a nation, something just as earthly. Their religion is essentially inseparable from such idolatry, because of the notion of the "chosen people".

No doubt you know that Galileo had been convicted not long ago by the Inquisition, and that his opinion on the movement of the Earth had been condemned as heresy. Now I will tell you that all things I explain in my treatise, among which is also that same opinion about the movement of the Earth, all depend on one another, and are based upon certain evident truths. Nevertheless, I will not for the world stand up against the authority of the Church. ...I have the desire to live in peace and to continue on the road on which I have started.

It is a serious thing to live in a society of possible gods and goddesses, to remember that the dullest most uninteresting person you talk to may one day be a creature which, if you saw it now, you would be strongly tempted to worship, or else a horror and a corruption such as you now meet, if at all, only in a nightmare. All day long we are, in some degree helping each other to one or the other of these destinations. It is in the light of these overwhelming possibilities, it is with the awe and the circumspection proper to them, that we should conduct all of our dealings with one another, all friendships, all loves, all play, all politics. There are no ordinary people. You have never talked to a mere mortal. Nations, cultures, arts, civilizations - these are mortal, and their life is to ours as the life of a gnat. But it is immortals whom we joke with, work with, marry, snub, and exploit - immortal horrors or everlasting splendors.

The consciousness of being betrayed is to the collective consciousness of a sacred group what a certain form of schizophrenia is to the individual...it is a form of madness.

The contradictory conceptual couple, identity and difference, is not the adequate framework for understanding the organization of the multitude. Instead we are a multiplicity of singular forms of life and at the same time share a common global existence. The anthropology of the multitude is an anthropology of singularity and commonality.

Even if I could by gradual degrees be transformed into a bat, nothing in my present constitution enables me to imagine what the experiences of such a future stage of myself thus metamorphosed would be like. The best evidence would come from the experience of bats, if we only knew what they were like.

The essence of the modern state is the union of the universal with the full freedom of the particular, and with the welfare of individuals.

National loyalty involves a love of home and a preparedness to defend it; nationalism is a belligerent ideology, which uses national symbols in order to conscript the people to war.

For as old age is that period of life most remote from infancy, who does not see that old age in this universal man ought not to be sought in the times nearest his birth, but in those most remote from it?

These labourers, who must sell themselves piecemeal, are a commodity, like every other article of commerce, and are consequently exposed to all the vicissitudes of competition, to all the fluctuations of the market.

Bacon, Locke, Descartes, Hume, and all the others knew they were giving rights to vulgarity. But in so doing-in addition to caring for man's well-being-they were providing rights for themselves.

Life is possible only by the deficiencies of our imagination and memory.

A hero looks death in the face, real death, not just the image of death. Behaving honourably in a crisis doesn't mean being able to act the part of a hero well, as in the theatre, it means being able to look death itself in the eye. For an actor may play lots of different roles, but at the end of it all he himself, the human being, is the one who has to die.

Do not be afraid. I am the First and the Last, and the living one, and I became dead, but look! I am living forever and ever, and I have the keys of death and of the Grave.

As one of our Swiss friends put it: "Now every German tailor living in Japan, China, or Moscow feels that he has the German navy and all of Germany's power behind him. This proud consciousness sends him into an insane rapture: the German has finally lived to see the day when he can say with pride, relying on his own state, like an Englishman or an American, 'I am a German.' True, when the Englishman or American says 'I am an Englishman,' or 'I am an American,' he is saying 'I am a free man.' The German, however, is saying 'I am a slave, but my emperor is stronger than all other princes, and the German soldier who is strangling me will strangle all of you.'"

When I was a boy, I had a clock with a pendulum that could be lifted off. I found that the clock went very much faster without the pendulum. If the main purpose of a clock is to go, the clock was the better for losing its pendulum. True, it could no longer tell the time, but that did not matter if one could teach oneself to be indifferent to the passage of time. The linguistic philosophy which cares only about language and not about the world, is like the boy who preferred the clock without the pendulum because, although it no longer told the time, it went more easily than before and at a more exhilarating pace.

On the frontiers of the self: "What I have suffered, what I am suffering, no one will ever know, not even I."

It is the duty of every man, so far as his ability extends, to detect and expose delusion and error.

Progress usually comes from the barbarian, and there is nothing more stagnant than the philosophy of the philosophers and the theology of the theologians.

There lay certitude; there, in the daily round. All the rest hung on mere threads and trivial contingencies; you couldn't waste your time on it. The thing was to do your job as it should be done.

We can get some idea of a whole from a part, but never knowledge or exact opinion. Special histories therefore contribute very little to the knowledge of the whole and conviction of its truth. It is only indeed by study of the interconnexion of all the particulars, their resemblances and differences, that we are enabled at least to make a general survey, and thus derive both benefit and pleasure from history.
