I will not accept boundaries; appearances cannot contain me; I choke! To bleed in this agony, and to live it profoundly, is the second duty. The mind is patient and adjusts itself, it likes to play; but the heart grows savage and will not condescend to play; it stifles and rushes to tear apart the nets of necessity.

Why don't I commit suicide? Because I am as sick of death as I am of life.

Far from diminishing the appetite for power, suffering exasperates it; hence the mind feels more comfortable in the society of a braggart than in that of a martyr; and nothing is more repugnant to it than the spectacle of dying for an idea.

Husserl has shown that man's prejudices go a great deal deeper than his intellect or his emotions. Consciousness itself is 'prejudiced' - that is to say, intentional.

Truth that has been merely learned is like an artificial limb, a false tooth, a waxen nose; at best, like a nose made out of another's flesh; it adheres to us only because it is put on. But truth acquired by thinking of our own is like a natural limb; it alone really belongs to us. This is the fundamental difference between the thinker and the mere man of learning. The intellectual attainments of a man who thinks for himself resemble a fine painting, where the light and shade are correct, the tone sustained, the colour perfectly harmonised; it is true to life. On the other hand, the intellectual attainments of the mere man of learning are like a large palette, full of all sorts of colours, which at most are systematically arranged, but devoid of harmony, connection and meaning.

If it is permissible to write plays that are not intended to be seen, I should like to see who can prevent me from writing a book no one can read.

A little of all things, but nothing of everything, after the French manner.

I am not concerned that I have no place; I am concerned how I may fit myself for one. I am not concerned that I am not known; I seek to be worthy to be known.

The pursuit of individual happiness within those limits prescribed by social conditions, is the first requisite to the attainment of the greatest general happiness.

Whatever is merely positive is lifeless. Negativity is essential to vitality.

A community is the mental and spiritual condition of knowing that the place is shared, and that the people who share the place define and limit the possibilities of each other's lives. It is the knowledge that people have of each other, their concern for each other, their trust in each other, the freedom with which they come and go among themselves.

In order to make himself thoroughly undesirable, he will speak.

Living virtuously is equal to living in accordance with one's experience of the actual course of nature.

In a well worn metaphor, a parallel is drawn between the life of man and the metamorphosis of the caterpillar into the butterfly; but the comparison may be more just as well as more novel, if for its former term we take the mental progress of the race. History shows that the human mind, fed by constant accessions of knowledge, periodically grows too large for its theoretical coverings, and bursts them asunder to appear in new habiliments, as the feeding and growing grub, at intervals, casts its too narrow skin and assumes another, itself but temporary. Truly the imago state of Man seems to be terribly distant, but every moult is a step gained, and of such there have been many.

An utterance can have Intentionality, just as a belief has Intentionality, but whereas the Intentionality of the belief is intrinsic the Intentionality of the utterance is derived.

The process of being brought up, however well it is done, cannot fail to offend.

Alexander's career was piracy pure and simple, nothing but an orgy of power and plunder, made romantic by the character of the hero. There was no rational purpose in it, and the moment he died his generals and governors attacked one another.

Adeimantus, in what amounts to an accusation of Socrates, asserts that the philosophers appear to be either useless or vicious. Plato, as I have suggested, teaches that ultimately this is an appearance that cannot be reversed, and this insures the philosophers' permanent marginality. They appear as useless because they are. They are neither artisans, nor statesmen, nor rhetoricians. They are idlers who contribute nothing to security or posterity. Their peculiar contemplative pleasures are not accessible to the majority of mankind, and they do not provide for the popular pleasures as do the poets.

To obey a rule, to make a report, to give an order, to play a game of chess, are customs.

The true University of these days is a Collection of Books.

Dear youths, I warn you cherish peace divine, And in your hearts lay deep these words of mine.

When shall we see poets born? After a time of disasters and great misfortunes, when harrowed nations begin to breathe again. And then, shaken by the terror of such spectacles, imaginations will paint things entirely strange to those who have not witnessed them.

Titles of property, for instance railway shares, may change hands every day, and their owner may make a profit by their sale even in foreign countries, so that titles to property are exportable, although the railway itself is not.

The phenomenon of the will in Epictetus, a different mental ability whose chief characteristic is that it speaks an imperative even when it commands nothing but our ability to think. The goal is to annihilate reality insofar it concerns me.

There are many kinds of gods. Therefore there are many kinds of men.

No sacrifice is lost for a great ideal!

That there is a common cause, an that it is either what we call material progress or something closely connected with material progress, becomes more than an inference when it is noted that the phenomena we class together and speak of as industrial depression are but intensifications of phenomena which always accompany material progress, and which show themselves more clearly and strongly as material progress goes on. Where the conditions to which material progress everywhere tends are the most fully realized-that is to say, where population is densest, wealth greatest, and the machinery of production and exchange most highly developed - we find the deepest poverty, the sharpest struggle for existence, and the most of enforced idleness.

We are alive within mystery, by miracle. "Life," wrote Erwin Chargaff, "is the continual intervention of the inexplicable." We have more than we can know. We know more than we can say. The constructions of language (which is to say the constructions of thought) are formed within experience, not the other way around. Finally we live beyond words, as also we live beyond computation and beyond theory. There is no reason whatever to assume that the languages of science are less limited than other languages.

The thesis of the identity of concept and thing is in general the vital nerve of idealist thought, and indeed traditional thought in general. ... Negative dialectics as critique means above all criticism of precisely this claim to identity.

Fame and tranquility can never be bedfellows.

In most men, the conscious and the unconscious being hardly ever make contact; consequently the conscious aim is to make himself as comfortable as possible with as little effort as possible. But there are other men, whom we have been calling, for convenience, 'Outsiders', whose conscious and unconscious being keep in closer contact, and the conscious mind is forever aware of the urge to care about 'more abundant life', and care less about comfort and stability and the rest of the notions that are so dear to the bourgeois.

Show me someone who is ill and yet happy, in danger and yet happy, dying and yet happy, exiled and yet happy. Show me such a person; by the gods, how greatly I long to see a Stoic!

The old dualistic notion of mind and matter, so prominent in Cartesianism, as two radically different kinds of substance, will hardly find defenders to-day. Rejecting this, we are driven to some form of hylopathy, otherwise called monism.

The premonition of madness is complicated by the fear of lucidity in madness, the fear of the moments of return and reunion, when the intuition of disaster is so painful that it almost provokes a greater madness. One would welcome chaos if one were not afraid of lights in it.

Only when they must choose between competing theories do scientists behave like philosophers.

A man who is free is like a mangy sheep in a herd. He will contaminate my entire kingdom and ruin my work.

Individuality, conceived as a temporal development involves uncertainty, indeterminacy, or contingency. Individuality is the source of whatever is unpredictable in the world.

When an astronomer tells me that some stellar phenomenon, which his telescope reveals to him at this moment, happened... fifty years ago... I... ask... how he has measured the velocity of light.

Surplus value is exactly equal to surplus labour; the increase of the one [is] exactly measured by the diminution of necessary labour.

There as here, passions are the motive of all action, but they are livelier, more ardent, or merely simpler and purer, thereby assuming a totally different character. All the first movements of nature are good and right.

The more powerful and original a mind, the more it will incline towards the religion of solitude.

Children must be under authority, and are themselves aware that they must be, although they like to play a game of rebellion at times. The case of children is unique in the fact that those who have authority over them are sometimes fond of them. Where this is the case, the children do not resent the authority in general, even when they resist it on particular occasions. Education authorities, as opposed to teachers, have not this merit, and do in fact sacrifice the children to what they consider the good of the State by teaching them "patriotism," i.e., a willingness to kill and be killed for trivial reasons.

You, your families, your friends and your countries are to be exterminated by the common decision of a few brutal but powerful men. To please these men, all the private affections, all the public hopes, all that has been achieved in art, and knowledge and thought and all that might be achieved hereafter is to be wiped out forever. Our ruined lifeless planet will continue for countless ages to circle aimlessly round the sun unredeemed by the joys and loves, the occasional wisdom and the power to create beauty which have given value to human life.
