Let no man be ashamed to speak what he is not ashamed to think.

Every morning I shall concern myself anew about the boundary Between the love-deed-Yes and the power-deed-No And pressing forward honor reality. We cannot avoid Using power, Cannot escape the compulsion To afflict the world, So let us, cautious in diction And mighty in contradiction, Love powerfully.

Animal Liberation is Human Liberation too.

Genius is always sufficiently the enemy of genius by over influence.

A masterpiece of art has in the mind a fixed place in the chain of being, as much as a plant or a crystal.

Words of the jargon sound as if they said something higher than what they mean.

The higher culture of the West-whose moral, aesthetic, and intellectual values industrial society still professes-was a pre-technological culture in a functional as well as chronological sense. Its validity was derived from the experience of a world which no longer exists and which cannot be recaptured because it is in a strict sense invalidated by technological society. Moreover, it remained to a large degree a feudal culture, even when the bourgeois period gave it some of its most lasting formulations. It was feudal not only because of its confinement to privileged minorities, not only because of its inherent romantic element (which will be discussed presently), but also because its authentic works expressed a conscious, methodical alienation from the entire sphere of business and industry, and from its calculable and profitable order.

The mass of men lead lives of quiet desperation. What is called resignation is confirmed desperation.

The concept of positivity in itself, in abstracto, has become part and parcel of the ideology today. ... Critique has started to become suspect, regardless of its content.

What is the Church? She is the body of Christ. Join to it the Head, and you have one man: The Head and the body make up one man. Who is the head? He who was born of the Virgin Mary. And what is His body? It is His Spouse, that is, the Church.... The Father willed that these two, the God Christ and the Church, should be one man. All men are one man in Christ, and the unity of the Christians constitutes but one man. And this man is all men, all men are this man; for all are one, since Christ is one.

There are two sentences inscribed upon the Delphic oracle, hugely accommodated to the usages of man's life: "Know thyself," and "Nothing too much;" and upon these all other precepts depend.

The unfortunate thing about public misfortunes is that everyone regards himself as qualified to talk about them.

The philosophy of physics is continuous with physics itself. Just as certain issues in the Foundations of Mathematics have been discussed by both mathematicians and by philosophers of mathematics, so certain issues in the philosophy of physics have been discussed by both physicists and by philosophers of physics. And just as there are issues of a more epistemological kind that tend to concern philosophers of mathematics more than they do working mathematicians, so there are issues that concern philosophers of physics more than they do working physicists.

At one time in his life the apostate radically changes his political, religious or philosophical convictions by taking up all possible means of argumentation against that which he formerly held to be true, and lives now for the sake of its negation. His new ideas and opinions consist in continuous acts of revenge on his spiritual past.

One can only become a philosopher, but not be one. As one believes he is a philosopher, he stops being one.

It cannot but happen that those individuals whose functions are most out of equilibrium with the modified aggregate of external forces, will be those to die; and that those will survive whose functions happen to be most nearly in equilibrium with the modified aggregate of external forces. But this survival of the fittest, implies multiplication of the fittest. Out of the fittest thus multiplied, there will, as before, be an overthrowing of the moving equilibrium wherever it presents the least opposing force to the new incident force.

Liberty, taking the word in its concrete sense, consists in the ability to choose.

They think of the philosopher as holding the ideal or subjective in one hand and the real or objective in the other and then have him strike the palms of his hands together so that one abrades the other. The product of this abrasion is the Absolute.

It is sad not to be loved, but it is much sadder not to be able to love.

We may define "faith" as a firm belief in something for which there is no evidence. Where there is evidence, no one speaks of "faith". We do not speak of faith that two and two are four or that the earth is round. We only speak of faith when we wish to substitute emotion for evidence. The substitution of emotion for evidence is apt to lead to strife, since different groups substitute different emotions.

I will not talk about people a thousand miles off, but come as near home as I can. As the time is short, I will leave out all the flattery, and retain all the criticism. Let us consider the way in which we spend our lives.

The strangest, most generous, and proudest of all virtues is true courage.

But the capacity to enjoy is impossible without the capacity to suffer; and the faculty of enjoyment is one with that of pain. Whosoever does not suffer does not enjoy, just as whosoever is insensible to cold is insensible to heat.

If thou wilt be perfect, go and sell that thou hast, and give to the poor, and thou shalt have treasure in heaven: and come and follow me.

In America a woman loses her independence for ever in the bonds of matrimony. While there is less constraint on girls there than anywhere else, a wife submits to stricter obligations. For the former, her father's house is a home of freedom and pleasure; for the latter, her husband's is almost a cloister.

The end of the philosophical dialogue lies in itself; it can never serve a purpose outside of itself. Just as a sculptor does not cease to be a work of art even if it lies at the bottom of the sea, so indeed every work of philosophy endures, even if uncomprehended in its own time. One would be grateful if it were merely a matter of incomprehension. Instead, the work is usually refitted and appropriated by various entities-some playing the part of the opponent; others, that of the proponent.

Chaos is rejecting all you have learned. Chaos is being yourself.

There is nothing more visible than what is secret, and nothing more manifest than what is minute. Therefore the superior man is watchful over himself, when he is alone.

Brutes are merely brutal; men and women are capable of being devils and lunatics. They are no less capable of being fully human-even, occasionally, of being a bit more than fully human, of being saints, heroes and geniuses.

Since he is unable to be the beloved, he will become the lover.

So long as it is not possible to produce so much that there is enough for all, with more left over for expanding the social capital and extending the forces of production - so long as this is not possible, there must always be a ruling class directing the use of society's productive forces, and a poor, oppressed class. How these classes are constituted depends on the stage of development.

In the part of this universe that we know there is great injustice, and often the good suffer, and often the wicked prosper, and one hardly knows which of those is the more annoying.

It is so by nature that the plant will develop with regularity, that the animal will move purposefully, and that human beings will think. Why should I take exception to recognizing also the last as the expression of an original force of nature, as I do the first and the second?

I read your piece on Plato. Holmes, when you strike at a king, you must kill him.

The propositions which are true and evident must of necessity be employed even by those who contradict them.

Once the first radical attack on private property has been launched, the proletariat will find itself forced to go ever further, to concentrate increasingly in the hands of the state all capital, all agriculture, all transport, all trade. All the foregoing measures are directed to this end; and they will become practicable and feasible, capable of producing their centralizing effects to precisely the degree that the proletariat, through its labor, multiplies the country's productive forces.

Philosophy, in one of its functions, is the critic of cosmologies. It is its function to harmonise, refashion, and justify divergent intuitions as to the nature of things. It has to insist on the scrutiny of the ultimate ideas, and on the retention of the whole of the evidence in shaping our cosmological scheme. Its business is to render explicit, and - so far as may be - efficient, a process which otherwise is unconsciously performed without rational tests.

The precarious ontological link between Logos and Eros is broken, and scientific rationality emerges as essentially neutral.

In contrast to "Blessed are they who do not see and still believe," he speaks of "seeing and still not believing."

I am almost inclined to set it up as a canon that a children's story which is enjoyed only by children is a bad children's story. The good ones last. A waltz which you can like only when you are waltzing is a bad waltz.

Not to be content with Life is the unsatisfactory state of those which destroy themselves; who being afraid to live, run blindly upon their own Death, which no Man fears by Experience.

Written words differ from spoken words in being material structures. A spoken word is a process in the physical world, having an essential time-order; a written word is a series of pieces of matter, having an essential space-order.

The concrete man has but one interest - to be right. That to him is the art of all arts, and all means are fair which help him to it.

To say that everything is idea or that everything is spirit, is the same as saying that everything is matter or that everything is energy, for if everything is idea or spirit, just as my consciousness is, it is not plain why the diamond should not endure for ever, if my consciousness, because it is idea or spirit, endures forever.

I cleave the heavens and soar to the infinite. And while I rise from my own globe to others And penetrate ever further through the eternal field, That which others saw from afar, I leave far behind me. Variant translation: While I venture out beyond this tiny globe Into reaches past the bounds of starry night I leave behind what others strain to see afar.

Ethics is in origin the art of recommending to others the sacrifices required for co-operation with oneself.

The notion of nothingness is not characteristic of laboring humanity: those who toil have neither time nor inclination to weigh their dust; they resign themselves to the difficulties or the doltishness of fate; they hope: hope is a slave's virtue.

But what then is this confrontation below the language of reason? Where might this interrogation lead, following not reason in its horizontal becoming, but seeking to retrace in time this constant verticality, which, the length of Western culture, confronts it with what it is not, measuring it with its own extravagance?

Much more naturally than you do: because flight is a much more natural consequence of fear than of hate. He doesn't flee men because he hates them, but because he is afraid of them. He doesn't flee them in order to harm them, but to try o escape the harm they wish to do to him. They, on the contrary, don't seek him through friendship, but through hate. They seek him and he flees from them just as in the wilderness of Africa, where there are few men and many tigers, the men flee the tigers, the men flee the tigers, and the tigers seek the men.
