The man who barely abstains from violating either the person, or the estate, or the reputation of his neighbours, has surely very little positive merit. He fulfils, however, all the rules of what is peculiarly called justice, and does every thing which his equals can with propriety force him to do, or which they can punish him for not doing. We may often fulfil all the rules of justice by sitting still and doing nothing.

Upon the progress of knowledge the whole progress of the human race is immediately dependent: he who retards that, hinders this also. And he who hinders this, -what character does he assume towards his age and posterity? Louder than with a thousand voices, by his actions he proclaims into the deafened ear of the world present and to come -"As long as I live at least, the men around me shall not become wiser or better; - for in their progress I too, notwithstanding all my efforts to the contrary, should be dragged forward in some direction; and this I detest I will not become more enlightened, - I will not become nobler. Darkness and perversion are my elements, and I will summon all my powers together that I may not be dislodged from them."

[on Epicurus] His starting point is a conviction that apathy is impossible, and that pleasure - though not necessarily sensual pleasure - is the only conceivable, and quite legitimate, end of life and action. "Nature leads every organism to prefer its own good to every other good" - even the stoic finds a subtle pleasure in renunciation. "We must not avoid pleasures, but we must select them". Epicurus, then, is no epicurean, he exalts the joys of intellect rather than those of sense; he warns against pleasures that excite and disturb the soul which they should rather quite and appease. In the end he proposes to seek not pleasure in its usual sense, but ataraxia - tranquility, equaninimity, repose of mind; all of which trembles on the verge of Zeno's "Apathy"

I neither deny nor affirm the immortality of man. I see no reason for believing in it, but, on the other hand, I have no means of disproving it.

Thought must never submit, neither to a dogma, nor to a party, nor to a passion, nor to an interest, nor to a preconceived idea, nor to whatever it may be, save to the facts themselves, because, for thought, submission would mean ceasing to be.

All ordinary expression may be explained causally, but creative expression which is the absolute contrary of ordinary expression, will be forever hidden from human knowledge.

My atheism, like that of Spinoza, is true piety towards the universe and denies only gods fashioned by men in their own image, to be servants of their human interests.

It's not that there are no differences between human and non-human animals, any more than there are no differences between black people and white people, freeborn citizens and slaves, men and women, Jews and gentiles, gays or heterosexuals. The question is rather: are they morally relevant differences? This matters because morally catastrophic consequences can ensue when we latch on to a real but morally irrelevant difference between sentient beings.

Habit is a second nature.

There are, in fact, people who appear to think only with the brain, or with whatever may be the specific thinking organ; while others think with all the body and all the soul, with the blood, with the marrow of the bones, with the heart, with the lungs, with the belly, with the life. And the people who think only with the brain develop into definition-mongers; they become the professionals of thought.

When people come to me saying they want to kill themselves, I tell them, "What's your rush? You can kill yourself any time you like. So calm down. Suicide is a positive act." And they do calm down.

You ask particularly after my health. I suppose that I have not many months to live; but, of course, I know nothing about it. I may add that I am enjoying existence as much as ever, and regret nothing.

Women dream till they have no longer the strength to dream; those dreams against which they so struggle, so honestly, vigorously, and conscientiously, and so in vain, yet which are their life, without which they could not have lived; those dreams go at last. All their plans and visions seem vanished, and they know not where; gone, and they cannot recall them. They do not even remember them. And they are left without the food of reality or of hope. Later in life, they neither desire nor dream, neither of activity, nor of love, nor of intellect. The last often survives the longest. They wish, if their experiences would benefit anybody, to give them to someone. But they never find an hour free in which to collect their thoughts, and so discouragement becomes ever deeper and deeper, and they less and less capable of undertaking anything.

We must be clear that when it comes to atoms, language can be used only as in poetry. The poet, too, is not nearly so concerned with describing facts as with creating images and establishing mental connections.

All honour to those who can abnegate for themselves the personal enjoyment of life, when by such renunciation they contribute worthily to increase the amount of happiness in the world; but he who does it, or professes to do it, for any other purpose, is no more deserving of admiration than the ascetic mounted on his pillar. He may be an inspiriting proof of what men can do, but assuredly not an example of what they should.

We can be knowledgeable with other men's knowledge, but we cannot be wise with other men's wisdom.

Once you've dissected a joke, you're about where you are when you've dissected a frog. It's dead. Banquets of the Black Widowers (1984), p. 49; comparable to "Humor can be dissected, as a frog can, but the thing dies in the process and the innards are discouraging to any but the pure scientific mind."

If we do not secure the foundation, we cannot secure the edifice.

Seldom, or perhaps never, does a marriage develop into an individual relationship smoothly and without crises; there is no coming to consciousness without pain.

The whole mystery of commodities, all the magic and necromancy that surrounds the products of labor as long as they take the form of commodities, vanishes therefore, so soon as we come to other forms of production.

1. Fidelity & Allegiance sworn to the King is only such a fidelity and obedience as is due to him by the law of the land; for were that faith and allegiance more than what the law requires, we would swear ourselves slaves, and the King absolute; whereas, by the law, we are free men, notwithstanding those Oaths. 2. When, therefore, the obligation by the law to fidelity and allegiance ceases, that by the Oath also ceases...

Time is the wisest of all things that are; for it brings everything to light.

I suppose you imagined I was so insanely in love with you that I could commit any folly. When will you women understand that one isn't insanely in love? All one asks for is a quiet life, which you won't allow one to have. I don't know what the devil ever induced me to marry you. It was all a damned stupid, practical joke. And now you go about saying I'm a murderer. I won't stand it.

The way out of this violent cycle is to deepen democracy-to bring decisions that directly affect people's lives as close as possible to where people are and to where they can take responsibility.

It is not you talking, but innumerable ancestors talking with your mouth. It is not you who desire, but innumerable generations of descendants longing with your heart. Your dead do not lie in the ground. They have become birds, trees, air. You sit under their shade, you are nourished by their flesh, you inhale their breathing. They have become ideas and passions, they determine your will and your actions. Future generations do not move far from you in an uncertain time. They live, desire, and act in your loins and your heart. In this lightning moment when you walk the earth, your first duty, by enlarging your ego, is to live through the endless march, both visible and invisible, of your own being.

Human beings can lose their lives in libraries. They ought to be warned.

Above all do not forget your duty to love yourself; do not permit the fact that you have been set apart from life in a way, been prevented from participating actively in it, and that you are superflous in the obtruse eyes of a busy world, above all, do not permit this to deprive you of your idea of yourself, as if your life, if lived in inwardness, did not have just as much meaning and worth as that of any human being in the eyes of all-wise Governance, and considerably more than the busy, busiest haste of busy-ness - busy with wasting life and losing itself.

The world's a bubble, and the life of man Less than a span.

National character is only another name for the particular form which the littleness, perversity and baseness of mankind take in every country. Every nation mocks at other nations, and all are right. Variant translation: Every nation criticizes every other one - and they are all correct.

Consider MacArthur and his Republican supporters. So limited is his intelligence and his imagination that he is never puzzled for one moment. All we have to do is to go back to the days of the Opium War. After we have killed a sufficient number of millions of Chinese, the survivors among them will perceive our moral superiority and hail MacArthur as a saviour. But let us not be one-sided. Stalin, I should say, is equally simple- minded and equally out of date. He, too, believes that if his armies could occupy Britain and reduce us all to the economic level of Soviet peasants and the political level of convicts, we should hail him as a great deliverer and bless the day when we were freed from the shackles of democracy. One of the painful things about our time is that those who feel certainty are stupid, and those with any imagination and understanding are filled with doubt and indecision.

The little world of childhood with its familiar surroundings is a model of the greater world. The more intensively the family has stamped its character upon the child, the more it will tend to feel and see its earlier miniature world again in the bigger world of adult life. Naturally this is not a conscious, intellectual process.

There were nowhere more docile disciples of Lenin, Trotsky and Stalin than the Nazis were.

A man might say, with enough truth to justify a joke: "Science is what we know, and philosophy is what we don't know." But it should be added that philosophical speculation as to what we do not yet know has shown itself a valuable preliminary to exact scientific knowledge.

The truth is, that the greatest enemies of the doctrine of Jesus are those, calling themselves the expositors of them, who have perverted them to the structure of a system of fancy absolutely incomprehensible, and without any foundation in his genuine words. And the day will come when the mystical generation of Jesus, by the supreme being as his father in the womb of a virgin will be classed with the fable of the generation of Minerva in the brain of Jupiter ... But may we hope that the dawn of reason and freedom of thought in these United States will do away with this artificial scaffolding, and restore to us the primitive and genuine doctrines of this most venerated reformer of human errors.

The greatness of the human being consists in this: that it is capable of the universe.

He will through life be master of himself and a happy man who from day to day can have said, "I have lived: tomorrow the Father may fill the sky with black clouds or with cloudless sunshine."

Having always lived in fear of being surprised by the worst, I have tried in every circumstance to get a head start, flinging myself into misfortune long before it occurred.

A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.

If it is not true, it is a good story.

The same feeling of not belonging, of futility, wherever I go: I pretend interest in what matters nothing to me, I bestir myself mechanically or out of charity, without ever being caught up, without ever being somewhere. What attracts me is elsewhere, and I don't know where that elsewhere is.

The principles of great men illuminate the universe.

In the effort to tell a whole story, to see it whole and clear, I have had to imagine more than I have known.

Our language can be seen as an ancient city: a maze of little streets and squares, of old and new houses, and of houses with additions from various periods; and this surrounded by a multitude of new boroughs with straight regular streets and uniform houses.

Liberalism, with its contradictions and compromises, existed for Donoso Cortés only in that short interim period in which it was possible to answer the question "Christ or Barabbas?" with a proposal to adjourn or appoint a commission of investigation.

A soldier told Pelopidas, "We are fallen among the enemies." Said he, "How are we fallen among them more than they among us?"

Labour was the first price, the original purchase-money that was paid for all things. It was not by gold or by silver, but by labour, that all the wealth of the world was originally purchased; and its value, to those who possess it, and who want to exchange it for some new productions, is precisely equal to the quantity of labour which it can enable them to purchase or command.

Obscenity is whatever happens to shock some elderly and ignorant magistrate.

A farewell does not dilute the presence of the past; it may make an even deeper presence.
