Brief and powerless is Man's life; on him and all his race the slow, sure doom falls pitiless and dark.

Don't turn back when you are just at the goal.

Such would be the successive phases of the image:it is the reflection of a profound reality;it masks and denatures a profound reality;it masks the absence of a profound reality;it has no relation to any reality whatsoever: it is its own pure simulacrum.In the first case, the image is a good appearance-representation is of the sacramental order. In the second, it is an evil appearance-it is of the order of maleficence. In the third, it plays at being an appearance-it is of the order of sorcery. In the fourth, it is no longer of the order of appearances, but of simulation.

Life seems to me essentially passion, conflict, rage... It is only intellect that keeps me sane; perhaps this makes me overvalue intellect against feeling.

Monsters cannot be announced. One cannot say: 'here are our monsters', without immediately turning the monsters into pets.

Freedom of thought and of expression are not mere rights to be claimed. They have their roots deep in the existence of individuals as developing careers in time. Their denial and abrogation is an abdication of individuality and a virtual rejection of time as opportunity.

The measure of a master is his success in bringing all men round to his opinion twenty years later.

Hayek fails to account either for the passion among intellectuals for equality, or for the resulting success of socialists and their egalitarian successors in driving the liberal idea from the stage of politics. This passion for equality is not a new thing, and indeed pre-dates socialism by many centuries, finding its most influential expression in the writings of Rousseau. There is no consensus as to how equality might be achieved, what it would consist in if achieved, or why it is so desirable in the first place. But no argument against the cogency or viability of the idea has the faintest chance of being listened to or discussed by those who have fallen under its spell.

In 1903 there appeared Problems of Idealism, a collection of essays many of whose authors had recently been Marxists, but which condemned Marxism and materialism for their moral nihilism, contempt of personality, determinism, and fanatical pursuit of social values regardless of the individuals who made up society; they also attacked Marxism for its uncritical worship of progress and sacrifice of the present to the future.

I think part of the appeal of mathematical logic is that the formulas look mysterious - you write backward Es!

I define a Sign as anything which is so determined by something else, called its Object, and so determines an effect upon a person, which effect I call its Interpretant, that the latter is thereby mediately determined by the former.

I say, it is the everlasting privilege of the foolish to be governed by the wise; to be guided in the right path by those who know it better than they. This is the first "right of man;" compared with which all other rights are as nothing.

The teacher of love teaches struggle. The teacher of lifeless isolation from the world teaches peace.

Rooted in freedom, bonded in the fellowship of danger, sharing everywhere a common human blood, we declare again that all men are brothers, and that mutual tolerance is the price of liberty.

A man possessed of splendid talents, which he often abused, and of a sound judgment, the admonitions of which he often neglected; a man who succeeded only in an inferior department of his art, but who in that department succeeded pre-eminently.

The slave is sold once and for all; the proletarian must sell himself daily and hourly. The individual slave, property of one master, is assured an existence, however miserable it may be, because of the master's interest. The individual proletarian, property as it were of the entire bourgeois class which buys his labor only when someone has need of it, has no secure existence. This existence is assured only to the class as a whole.

What is marvelous is that each day brings us a new reason to disappear.

I'd rather be ruled by a competent Turk than an incompetent Christian.

Consciousness presupposes itself, and asking about its origin is an idle and just as sophistical a question as that old one, "What came first, the fruit-tree or the stone? Wasn't there a stone out of which came the first fruit-tree? Wasn't there a fruit-tree from which came the first stone?

I am not virtuous. Our sons will be if we shed enough blood to give them the right to be.

The administration of the great system of the universe, however, the care of the universal happiness of all rational and sensible beings, is the business of God and not of man. To man is allotted a much humbler department, but one much more suitable to the weakness of his powers, and to the narrowness of his comprehension; the care of his own happiness, of that of his family, his friends, his country: that he is occupied in contemplating the more sublime, can never be an excuse for his neglecting the more humble department.

Is it really not possible to touch the gaming table without being instantly infected by superstition?

Europe owes its greatness to the fact that the primary loyalties of the European people have been detached from religion and re-attached to the land. Those who believe that the division of Europe into nations has been the primary cause of European wars should remember the devastating wars of religion that national loyalties finally brought to an end. And they should study our art and literature for its inner meaning. In almost every case, they will discover, it is an art and literature not of war but of peace, an invocation of home and the routines of home, of gentleness, everydayness and enduring settlement.

Reason as an organ for perceiving the true nature of reality and determining the guiding principles of our lives has come to be regarded as obsolete.

First of all: what is work? Work is of two kinds: first, altering the position of matter at or near the earth's surface relatively to other such matter; second, telling other people to do so. The first kind is unpleasant and ill paid; the second is pleasant and highly paid.

I would in fact tend to have more confidence in the outcome of a democratic decision if there was a minority that voted against it, than if it was unanimous... Social psychology has amply shown the strength of this bandwagon effect.

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.

What pride to discover that nothing belongs to you - what a revelation.

The presence of a thought is like the presence of a lover.

A good education would be devoted to encouraging and refining the love of the beautiful, but a pathologically misguided moralism instead turns such longing into a sin against the high goal of making everyone feel good, of overcoming nature in the name of equality. ... Love of the beautiful may be the last and finest sacrifice to radical egalitarianism.

The superior man, while there is anything he has not studied, or while in what he has studied there is anything he cannot understand, Will not intermit his labor. While there is anything he has not inquired about, or anything in what he has inquired about which he does not know, he will not intermit his labor. While there is anything which he has not reflected on, or anything in what he has reflected on which he does not apprehend, he will not intermit his labor. While there is anything which he has not discriminated or his discrimination is not clear, he will not intermit his labor. If there be anything which he has not practiced, or his practice fails in earnestness, he will not intermit his labor. If another man succeed by one effort, he will use a hundred efforts. If another man succeed by ten efforts, he will use a thousand. Let a man proceed in this way, and, though dull, he will surely become intelligent; though weak, he will surely become strong.

That is the best government which desires to make the people happy, and knows how to make them happy.

Love, a tacit agreement between two unhappy parties to overestimate each other. p. 111, first American edition

Kings will be tyrants from policy, when subjects are rebels from principle.

Childish and altogether ludicrous is what you yourself are and all philosophers; and if a grown-up man like me spends fifteen minutes with fools of this kind, it is merely a way of passing the time. I've now got more important things to do. Goodbye!

Seeing therefore they are both [heat and pain] immediately perceived at the same time, and the fire affects you only with one simple, or uncompounded idea, it follows that this same simple idea is both the intense heat immediately perceived, and the pain; and consequently, that the intense heat immediately perceived, is nothing distinct from a particular sort of pain.

As medium for reaching understanding, speech acts serve: a) to establish and renew interpersonal relations, whereby the speaker takes up a relation to something in the world of legitimate social orders; b) to represent states and events, whereby the speaker takes up a relation to something in the world of existing states of affairs; c) to manifest experiences that is, to represent oneself- whereby the speaker takes up a relation to something in the subjective world to which he has privileged access.

Our design, not respecting arts, but philosophy, and our subject, not manual, but natural powers, we consider chiefly those things which relate to gravity, levity, elastic force, the resistance of fluids, and the like forces, whether attractive or impulsive; and therefore we offer this work as mathematical principles of philosophy; for all the difficulty of philosophy seems to consist in this - from the phenomena of motions to investigate the forces of nature, and then from these forces to demonstrate the other phenomena...

Better a diamond with a flaw than a pebble without.

If anyone would like to acquire humility, I can, I think, tell him the first step. The first step is to realise that one is proud. And a biggish step, too. At least, nothing whatever can be done before it. If you think you are not conceited, it means you are very conceited indeed.

To be a philosopher, that is to say, a lover of wisdom (for wisdom is nothing but truth), it is not enough for a man to love truth, in so far as it is compatible with his own interest, with the will of his superiors, with the dogmas of the church, or with the prejudices and tastes of his contemporaries; so long as he rests content with this position, he is only a philautos, not a philosophos [a lover of self, not a lover of wisdom]. For this title of honor is well and wisely conceived precisely by its stating that one should love the truth earnestly and with one's whole heart, and thus unconditionally and unreservedly, above all else, and, if need be, in defiance of all else. Now the reason for this is the one previously stated that the intellect has become free, and in this state it does not even know or understand any other interest than that of truth.

The main business of religions is to purify, control, and restrain that excessive and exclusive taste for well-being which men acquire in times of equality.

It repudiates, as something vile and sinful, our deepest feelings; but being absolutely ignorant as to the real functions of human emotions, Puritanism is itself the creator of the most unspeakable vices.

For as soon as the distribution of labour comes into being, each man has a particular exclusive sphere of activity, which is forced upon him and from which he cannot escape. He is a hunter, a fisherman, a shepherd, or a critical critic and must remain so if he does not wish to lose his means of livelihood; while in communist society, where nobody has one exclusive sphere of activity but each can become accomplished in any branch he wishes, society regulates the general production and thus makes it possible for me to do one thing today and another tomorrow, to hunt in the morning, to fish in the afternoon, rear cattle in the evening, criticize after dinner, just as I have in mind, without ever becoming hunter, fisherman, shepherd or critic.

Go into the London Stock Exchange - a more respectable place than many a court - and you will see representatives from all nations gathered together for the utility of men. Here Jew, Mohammedan and Christian deal with each other as though they were all of the same faith, and only apply the word infidel to people who go bankrupt. Here the Presbyterian trusts the Anabaptist and the Anglican accepts a promise from the Quaker.

We do not have to love one another to be obligated to build a world in which all lives are sustainable. The right to persist can only be understood as a social right, as the subjective instance of a social and global obligation we bear toward one another.

This life is worth living, we can say, since it is what we make it, from the moral point of view.

Logic chases truth up the tree of grammar.

The limits of this strategy were evident as the century drew to a close.
