Never aim at more precision than... required by the problem...

The mind which is free from passions is a citadel, for man has nothing more secure to which he can fly for refuge and for the future be inexpugnable. He then who has not seen this is an ignorant man: but he who has seen it and does not fly to this refuge is unhappy.

He not only overflowed with learning but stood in the slops.

Every man I meet is in some way my superior, and in that, I can learn of him.

Sleep is a death; oh, make me try By sleeping what it is to die, And as gently lay my head On my grave as now my bed.

I believe in the possible realization of a world in which man can be much, even if he has little; a world in which the dominant motivation of existence is not consumption; a world in which "man" is the end, first and last; a world in which man can find the way of giving a purpose to his life as well as the strength to live free and without illusions.

To shoot down a European is to kill two birds with one stone, to destroy an oppressor and the man he oppresses at the same time.

The safest road to Hell is the gradual one - the gentle slope, soft underfoot, without sudden turnings, without milestones, without signposts.

Receive an injury rather than do one.

Ethics is inescapable.

The ancient Egyptians had a superstitious antipathy to the sea; a superstition nearly of the same kind prevails among the Indians; and the Chinese have never excelled in foreign commerce.

You never have to change anything you got up in the middle of the night to write.

To think is to run after insecurity, to be demoralized for grandiose trifles, to immure oneself in abstractions with a martyr's avidity, to hunt up complications the way others pursue collapse or gain. The thinker is by definition keen for torment.

The order of nature cannot be justified by the mere observation of nature. For there is nothing in the present fact which inherently refers either to the past or to the future.... It illustrates the anti-rationalism of the scientific public that, when Hume did appear, it was only the religious implications of his philosophy which attracted attention. This was because the clergy were in principle rationalists, whereas the men of science were content with a simple faith in the order of nature.

The history of science is full of revolutionary advances that required small insights that anyone might have had, but that, in fact, only one person did.

May not this religious reticence, in these devout good souls, be perhaps a merit, and sign of health in them? Jocelin, Eadmer, and such religious men, have as yet nothing of 'Methodism;' no Doubt or even root of Doubt. Religion is not a diseased self-introspection, an agonising inquiry: their duties are clear to them, the way of supreme good plain, indisputable, and they are traveling on it. Religion lies over them like an all-embracing heavenly canopy, like an atmosphere and life-element, which is not spoken of, which in all things is presupposed without speech. Is not serene or complete Religion the highest aspect of human nature.

It is soft, smooth and shining like intelligence. Its edges seem sharp but do not cut like justice. It hangs down to the ground like humility. When struck, it gives a clear, ringing sound like music. The strains in it are not hidden and add to its beauty like truthfulness.' What imagination! Confucius extolled Jade's virtues this way.

In the performance of an illocutionary act in the literal utterance of a sentence, the speaker intends to produce a certain effect by means of getting the hearer to recognize his intention to produce that effect; and furthermore, if he is using the words literally, he intends this recognition to be achieved in virtue of the fact that the rules for using the expressions he utters associate the expression with the production of that effect.

Paradox is the technique for seizing the conflicting aspects of any problem. Paradox coalesces or telescopes various facets of a complex process in a single instant.

Poetry teaches the enormous force of a few words, and, in proportion to the inspiration, checks loquacity.

These people who have fled inward for their freedom also have to live outwardly, become visible, let themselves be seen; they are united with mankind through countless ties of blood, residence, education, fatherland, chance, the importunity of others; they are likewise presupposed to harbour countless opinions simply because these are the ruling opinions of the time; every gesture which is not clearly a denial counts as agreement.

Nay, men, if any of you had heeded what I was ever foretelling and advising, ye would now neither be fearing a single man nor putting your hopes in a single man.

When one told Plistarchus that a notorious railer spoke well of him, "I 'll lay my life," said he, "somebody hath told him I am dead, for he can speak well of no man living."

Great and enduring civilizations like those of the Hindus and the Chinese were built upon this foundation and developed from it a discipline of self-knowledge which they brought to a high pitch of refinement both in philosophy and practice.

Since it is Reason which shapes and regulates all other things, it ought not itself to be left in disorder.

Irons and the unbreathable air of this world strip us of everything, except the freedom to kill ourselves; and this freedom grants us a strength and pride to triumph over the loads which overwhelm us.

Universal love is really the way of the sage-kings. It is what gives peace to the rulers and sustenance to the people. The gentleman would do well to understand and practise universal love; then he would be gracious as a ruler, loyal as a minister, affectionate as a father, filial as a son, courteous as an elder brother, and respectful as a younger brother. So, if the gentleman desires to be a gracious ruler, a loyal minister, an affectionate father, a filial son, a courteous elder brother, and a respectful younger brother, universal love must be practised. It is the way of the sage-kings and the great blessing of the people.

To conceive a thought - just one, but one that would tear the universe to pieces.

Wars have never made peace or preserved it or fostered its ideals. To have peace you must make peace with your enemy. To make peace only with your friends is to avoid the issue, and to permit a great principle to become absurd. Far from making peace, wars invariably serve as classrooms and laboratories where men and techniques and states of mind are prepared for the next war.

The self-discipline of the Social Democracy is not merely the replacement of the authority of bourgeois rulers with the authority of a socialist central committee. The working class will acquire the sense of the new discipline, the freely assumed self-discipline of the Social Democracy, not as a result of the discipline imposed on it by the capitalist state, but by extirpating, to the last root, its old habits of obedience and servility.

Continuously thou wilt look at human things as smoke and nothing at all; especially if thou reflectest at the same time, that what has once changed will never exist again in the infinite duration of time. But thou, in what a brief space of time is thy existence? And why art thou not content to pass through this short time in an orderly way?

One should be wary of assuming that we're the folk who can properly look after ourselves, whereas our descendants, if they become genetically pre-programmed ecstatics, will get trapped in robot-serviced states of infantile dependence. For it shouldn't be forgotten that exuberantly happy people also have a fierce will to survive. They love life dearly. They take on daunting challenges against seemingly impossible odds. One of the hallmarks of many endogenous depressive states, on the other hand, is so-called behavioural despair. If one learns that apparently no amount of effort can rescue one from an aversive stimulus, then one tends to sink into a lethargic stupor. This syndrome of "learned helplessness" may persist even when the opportunity to escape from the nasty stimulus subsequently arises.

Well, Prince, so Genoa and Lucca are now just family estates of the Buonapartes. But I warn you, if you don't tell me that this means war, if you still try to defend the infamies and horrors perpetrated by that Antichrist-I really believe he is Antichrist-I will have nothing more to do with you and you are no longer my friend, no longer my 'faithful slave,' as you call yourself! But how do you do? I see I have frightened you-sit down and tell me all the news.

Man desires to praise thee, for he is a part of thy creation; he bears his mortality about with him and carries the evidence of his sin and the proof that thou dost resist the proud. Still he desires to praise thee, this man who is only a small part of thy creation. Thou hast prompted him, that he should delight to praise thee, for thou hast made us for thyself and restless is our heart until it comes to rest in thee.

Common sense doesn't have the last word in ethics or anywhere else, but it has, as J. L. Austin said about language, the first word: it should be examined before it is discarded.

I have been writing & speaking what were once called novelties, for twenty five or thirty years, & have not now one disciple. Why? Not that what I said was not true; not that it has not found intelligent receivers but because it did not go from any wish in me to bring men to me, but to themselves. I delight in driving them from me. What could I do, if they came to me? - they would interrupt and encumber me. This is my boast that I have no school & no follower. I should account it a measure of the impurity of insight, if it did not create independence.

For lack of empirical data I have neither knowledge nor understanding of such forms of being, which are commonly called spiritual. ...Nevertheless, we have good reason to suppose that behind this veil there exists the uncomprehended absolute object which affects and influences us-and to suppose it even, or particularly, in the case of psychic phenomena about which no verifiable statements can be made.

People often say to me, You don't know what a wife and mother feels. No, I say, I don't and I'm very glad I don't. And they don't know what I feel. ... I am sick with indignation at what wives and mothers will do of the most egregious selfishness. And people call it all maternal or conjugal affection, and think it pretty to say so. No, no, let each person tell the truth from his own experience.

Unlimited exploitation of cheap labour-power is the sole foundation of their power to compete.

We believe that the very beginning and end of salvation, and the sum of Christianity, consists of faith in Christ, who by His blood alone, and not by any works of ours, has put away sin, and destroyed the power of death.

As long as one believes in philosophy, one is healthy; sickness begins when one starts to think.

People are not aware how entirely, in former ages, the law of superior strength was the rule of life; how publicly and openly it was avowed, I do not say cynically or shamelessly - for these words imply a feeling that there was something in it to be ashamed of, and no such notion could find a place in the faculties of any person in those ages, except a philosopher or a saint.

The man who is honest and good ought to be exactly like a man who smells strong, so that the bystander as soon as he comes near him must smell whether he choose or not.

The deliberate aim at Peace very easily passes into its bastard substitute, Anesthesia.
