All abstract sciences are nothing but the study of relations between signs.

Nietzsche was the first to release the desire to know from the sovereignty of knowledge itself: to re-establish the distance and exteriority that Aristotle cancelled.

We are taught to believe that a desire of domineering over our countrymen is love to our country; and those who hate civil war abet rebellion, and that the amiable and conciliatory virtues of lenity, moderation, and tenderness to the privileges of those who depend on this kingdom are a sort of treason to the state. It is impossible that we should remain long in a situation, which breeds such notions and dispositions, without some great alteration in the national character.

The Word takes to Himself one man, for He takes unity. He does not take schisms to Himself, nor does He take heresies. So it is one man who is taken, and his Head is Christ. This is that "blessed man who hath not walked in the council of the ungodly" (Ps. 1:1); this is he that is assumed. He is not outside of us. Let us be in Him, and we shall be assumed; let us be in Him, and we shall be chosen. Therefore this one man that is taken to become the temple of God, is at once many and one.

When we cannot obtain a thing, we comfort ourselves with the reassuring thought that it is not worth nearly as much as we believed.

The paradox of race in America is that our common destiny is more pronounced and imperiled precisely when our divisions are deeper.

Hitch your wagon to a star.

There is always someone above you: beyond God Himself rises Nothingness.

And suddenly I had an inkling of what it must feel like to be mad.

Marcus Garvey, Elijah Muhammad, Malcolm X, Martin Luther King, Stokely Carmichael, Amiri Baraka and other black male leaders have righteously supported patriarchy. They have all argued that it is absolutely necessary for black men to relegate black women to a subordinate position both in the political sphere and in home life.

Some people talk as if meeting the gaze of absolute goodness would be fun. They need to think again. They are still only playing with religion. Goodness is either the great safety or the great danger-according to the way you react to it.

The reward in heaven is the perpetual bait, a bait that has caught man in an iron net, a strait-jacket which does not let him expand or grow. All pioneers of truth have been, and still are, reviled; they have been, and still are, persecuted. But did they ask humanity to pay the price? Did they seek to bribe mankind to accept their ideas? They knew too well that he who accepts a truth because of the bribe, will soon barter it away to a higher bidder...Proud and self-reliant characters prefer hatred to such sickening artificial love. Not because of any reward does a free spirit take his stand for a great truth, nor has such a one ever been deterred because of fear of punishment.

Advertising is the greatest art form of the twentieth century.

It is not my aim to surprise or shock you - but the simplest way I can summarize is to say that there are now in the world machines that think, that learn and that create. Moreover, their ability to do these things is going to increase rapidly until - in a visible future - the range of problems they can handle will be coextensive with the range to which the human mind has been applied.

Space and time are commonly regarded as the forms of existence of the real world, matter as its substance. A definite portion of matter occupies a definite part of space at a definite moment of time. It is in the composite idea of motion that these three fundamental conceptions enter into intimate relationship.

The only man for whom Hitler had "unqualified respect" was "Stalin the genius," and while in the case of Stalin and the Russian regime we do not... have the rich documentary material that is available for Germany, we nevertheless know since Khrushchev's speech before the Twentieth Party Congress that Stalin trusted only one man and that was Hitler.

Scepticism is not irrefutable, but obviously nonsensical, when it tries to raise doubts where no questions can be asked. For doubt can exist only where a question exists, a question only where an answer exists, and an answer only where something can be said.

Those who used to sacrifice animals did not take them for beasts. And even the Middle Ages, which condemned and punished them in due form, was in this way much closer to them than we are, we who are filled with horror at this practice. They held them to be guilty: which was a way of honoring them. We take them for nothing, and it is on this basis that we are "human" with them. We no longer sacrifice them, we no longer punish them, and we are proud of it, but it is simply that we have domesticated them, worse: that we have made of them a racially inferior world, no longer even worthy of our justice, but only of our affection and social charity, no longer worthy of punishment and of death, but only of experimentation and extermination like meat from the butchery.

There are more things, Lucilius, likely to frighten us than there are to crush us; we suffer more often in imagination than in reality.

We should never take pleasure in causing pain to others, even to those who have wronged us, but rather strive to do good to all.

If a captive mind is unaware of being in prison, it is living in error. If it has recognized the fact, even for the tenth of a second, and then quickly forgotten it in order to avoid suffering, it is living in falsehood. Men of the most brilliant intelligence can be born, live and die in error and falsehood. In them, intelligence is neither a good, nor even an asset. The difference between more or less intelligent men is like the difference between criminals condemned to life imprisonment in smaller or larger cells. The intelligent man who is proud of his intelligence is like a condemned man who is proud of his large cell.

A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.

This is how I recognize an authentic poet: by frequenting him, living a long time in the intimacy of his work, something changes in myself, not so much my inclinations or my tastes as my very blood, as if a subtle disease had been injected to alter its course, its density and nature. To live around a true poet is to feel your blood run thin, to dream a paradise of anemia, and to hear, in your veins, the rustle of tears.

What is called an acute knowledge of human nature is mostly nothing but the observer's own weaknesses reflected back from others.

In books of psychology written from the spiritualist point of view, it is customary to begin the discussion of the existence of the soul as a simple substance, separable from the body, after this style: There is in me a principle which thinks, wills and feels... Now this implies a begging of the question. For it is far from being an immediate truth that there is in me such a principle; the immediate truth is that I think, will and feel. And I - the I that thinks, wills and feels - am immediately my living body with the states of consciousness which it sustains. It is my living body that thinks, wills and feels.

When Scipio became consul and was keen on getting the province of Africa, promising that Carthage should be completely destroyed, and the senate would not agree to this because Fabius Maximus was against it, he threatened to appeal to the people, for he knew full well how pleasing such projects are to the populace.

We refuse to have our conscience bound by any work or law, so that by doing this or that we should be righteous, or leaving this or that undone we should be damned.

Americans cleave to the things of this world as if assured that they will never die,... They clutch everything but hold nothing fast, and so lose grip as they hurry after some new delight. ... Death steps in in the end and stops him before he has grown tired of this futile pursuit of that complete felicity which always escapes him. At first sight there is something astonishing in this spectacle of so many lucky men restless in the midst of abundance. But it is a spectacle as old as the world; all that is new is to see a whole people performing in it.

Powerful indeed is the empire of habit.

This proof can at most, therefore, demonstrate the existence of an architect of the world, whose efforts are limited by the capabilities of the material with which he works, but not of a creator of the world, to whom all things are subject.

We are far more liable to catch the vices than the virtues of our associates.

The condition of life to which people of the well-to-do classes are accustomed is that of an abundant production of various articles necessary for their comfort and pleasure, and these things are obtained only thanks to the existence of factories and works organized as at present. And, therefore, discussing the improvement of the workers' position, the men of science belonging to the well- to-do classes always have in view only such improvements as will not do away with the system of factory-production and those conveniences of which they avail themselves.

I mean, a genuinely productive society. I mean you could produce plenty of goods without much freedom, but I think the whole sort of creative life of man is ultimately impossible without a considerable measure of individual freedom, of initiative, creation, all these things which we value, and I think value properly, are impossible without a large measure of freedom.

What is morality in any given time or place? It is what the majority then and there happen to like, and immorality is what they dislike.

As there are a very great variety of religious sects in the world (and which are probably adapted to different constitutions under different circumstances, seeing there are many good and conscientious characters in each), it is particularly recommended, as a means of uniting the inhabitants of the village into one family, that while each faithfully adheres to the principles which he most approves, at the same time all shall think charitably of their neighbours respecting their religious opinions, and not presumptuously suppose that theirs alone are right.

The present state of France was ten times worse than a tyranny. The new constitution was said to be an experiment but the assertion was not true. It had already been tried, and had been found to be only productive of evils. They would go on from tyranny to tyranny, from oppression to oppression, till at last the whole system would terminate in the destruction of that miserable and deluded people... He sincerely hoped that no member of that House would ever barter the constitution of this country, the eternal jewel of their souls, for a wild and visionary system, which could only lead to confusion and disorder.

No nation keeps its word. A nation is a big, blind worm, following what? Fate perhaps. A nation has no honour, it has no word to keep. ... Hitler is himself the nation. That incidentally is why Hitler always has to talk so loud, even in private conversation - because he is speaking with 78 million voices.

With Leibnitz the extent to which thoughts advance is the extent of the universe; where comprehension ceases, the universe ceases, and God begins: so that later it was even maintained that to be comprehended was derogatory to God, because He was thus degraded into finitude. In that procedure a beginning is made from the determinate, this and that are stated to be necessary; but since in the next place the unity of these moments is not comprehended, it is transferred to God. God is therefore, as it were, the waste channel into which all contradictions flow: Leibnitz's Théodicée is just a popular summing up such as this.

Our trouble is that we have ignored and thus feel insecure in the enormous spectrum of love which lies between rather formal friendship and genital sexuality, and thus are always afraid that once we overstep the bounds of formal friendship we must slide inevitably to the extreme of sexual promiscuity.

A free press is not a privilege but an organic necessity in a great society. ...Without criticism and reliable and intelligent reporting, the government cannot govern. For there is no adequate way in which it can keep itself informed about what the people of the country are thinking and doing and wanting.

Error is the price we pay for progress.

It would seem that common sense and reason ought to find a way to reach agreement in every conflict of honest interests. I myself think it our bounden duty to believe in such international rationality as possible. But, as things stand, I see how desperately hard it is to bring the peace-party and the war-party together, and I believe that the difficulty is due to certain deficiencies in the program of pacifism which set the military imagination strongly, and to a certain extent justifiably, against it. In the whole discussion both sides are on imaginative and sentimental ground. It is but one utopia against another, and everything one says must be abstract and hypothetical.

Your worst sin is that you have destroyed and betrayed yourself for nothing.

I will not by suppression, or by performing tricks, try to produce the impression that the ordinary Christianity in the land and the Christianity of the New Testament are alike. "What Do I Want?"

It has been said a thousand times and in a thousand books that ancestor-worship is for the most part the source of primitive religions, and it may be strictly said that what most distinguishes man from the other animals is that, in one form or another, he guards his dead and does not give them over to the neglect of teeming mother earth; he is an animal that guards its dead.

I don't believe you until you tell me, do you really believe, for example, if they say they are Catholic, "Do you really believe that when a priest blesses a wafer, it turns into the body of Christ? Are you seriously telling me you believe that? Are you seriously saying that wine turns into blood?" Mock them. Ridicule them. In public. Don't fall for the convention that we're all too polite to talk about religion. Religion is not off the table. Religion is not off limits. Religion makes specific claims about the universe which need to be substantiated and need to be challenged and, if necessary, need to be ridiculed with contempt.

Men of learning are those who have read the contents of books. Thinkers, geniuses, and those who have enlightened the world and furthered the race of men, are those who have made direct use of the book of the world.

The state is therefore everyone; the rules within the state are laws which safeguard the welfare of all and which must originate from the welfare of all.

Being a planetary citizen does not need space travel. It means being conscious that we are part of the universe and of the earth. The most fundamental law is to recognise that we share the planet with other beings, and that we have a duty to care for our common home.
