A new theory by the author has been added, which draws the physical inferences consequent on the extension of the foundations of geometry beyond Reimann... and represents an attempt to derive from world-geometry not only gravitational but also electromagnetic phenomena. Even if this theory is still only in its infant stage, I feel convinced that it contains no less truth than Einstein's Theory of Gravitation-whether this amount of truth is unlimited or, what is more probable, is bounded by the Quantum Theory.

The good life is one inspired by love and guided by knowledge.

The prospects of revolution seem therefore quite restricted. For can a revolution avoid war? It is, however, on this feeble chance that we must stake everything or abandon all hope. An advanced country will not encounter, in the case of revolution, the difficulties which in backward Russia served as a base for the barbarous regime of Stalin. But a war of any scope will give rise to others as formidable.

All religions are cruel, all founded on blood; for all rest principally on the idea of sacrifice - that is, on the perpetual immolation of humanity to the insatiable vengeance of divinity.

Just now, when every one is bound, under pain of a decree in absence convicting them of lèse-respectability, to enter on some lucrative profession, and labour therein with something not far short of enthusiasm, a cry from the opposite party, who are content when they have enough.

It is the same thing: killing, dying, it is the same thing: one is just as alone in each. He is lucky, he will only die once. As for me, for ten days I have been killing him at every minute. Hugo to Jessica, on his plans to kill.

To sum up all these steps, each of which is very lengthy and complex, we will have put the game of truth back in the network of constraints and dominations. Truth, I should say rather, the system of truth and falsity, will have revealed the face it turned away from us for so long and which is that of its violence.

The English are a dumb people. They can do great acts, but not describe them.

Nature ... is inexorable and immutable; she never transgresses the laws imposed upon her, or cares a whit whether her abstruse reasons and methods of operation are understandable to men. For that reason it appears that nothing physical which sense-experience sets before our eyes, or which necessary demonstrations prove to us, ought to be called in question (much less condemned) upon the testimony of biblical passages which may have some different meaning beneath their words. For the Bible is not chained in every expression to conditions as strict as those which govern all physical effects; nor is God any less excellently revealed in Nature's actions than in the sacred statements of the Bible.

Does anyone bathe in a mighty little time? Don't say that he does it ill, but in a mighty little time. Does anyone drink a great quantity of wine? Don't say that he does ill, but that he drinks a great quantity. For, unless you perfectly understand the principle from which anyone acts, how should you know if he acts ill? Thus you will not run the hazard of assenting to any appearances but such as you fully comprehend.

A marvel that has nothing to offer, democracy is at once a nation's paradise and its tomb.

Man's main task in life is to give birth to himself, to become what he potentially is. The most important product of his effort is his own personality.

The native and untaught suggestions of inquisitive children do often offer things, that may set a considering man's thoughts on work. And I think there is frequently more to be learn'd from the unexpected questions of a child than the discourses of men, who talk in a road, according to the notions they have borrowed, and the prejudices of their education.

A Turk thinks, or used to think (for even Turks are wiser now-a-days), that society would be on a sandbank if women were suffered to walk about the streets with their faces uncovered. Taught by these and many similar examples, I look upon this expression of loosening the foundations of society, unless a person tells in unambiguous terms what he means by it, as a mere bugbear to frighten imbeciles with.

I shall never be ashamed of citing a bad author if the line is good.

Indian thought has greatly attracted me since in my youth I first became acquainted with it through reading the works of Arthur Schopenhauer. From the very beginning I was convinced that all thought is really concerned with the great problem of how man can attain to spiritual union with infinite Being. My attention was drawn to Indian thought because it is busied with this problem and because by its nature it is mysticism. What I liked about it also was that Indian ethics are concerned with the behaviour of man to all living beings and not merely with his attitude to his fellow-man and to human society.

A fire eater must eat fire even if he has to kindle it himself.

The absurd does not liberate; it binds. It does not authorize all actions. "Everything is permitted" does not mean that nothing is forbidden.

Amy Kofman: Have you read all the books in here?Derrida: No, only four of them. But I read those very, very carefully.

I suggest that scientific knowledge, though logically more articulate and far more complex, is of this sort. The books and teachers from whom it is acquired present concrete examples together with a multitude of theoretical generalizations. Both are essential carriers of knowledge, and it is therefore Pickwickian to seek a methodological criterion that supposes the scientist can specify in advance whether each imaginable instance fits or would falsify his theory.

To believe in God is to yearn for His existence and, furthermore, it is to act as if He did exist.

How absurd men are! They never use the liberties they have, they demand those they do not have. They have freedom of thought, they demand freedom of speech. Either/Or Part I, Swenson Translation p. 19 Variations include: People demand freedom of speech to make up for the freedom of thought, which they avoid. People demand freedom of speech as a compensation for the freedom of thought which they seldom use.

In our fear, we are victims of an aggression of the Future.

... in such a matter he would never have been guided by his first thoughts (which would probably have been right) nor even by his twenty-first (which would have at least been explicable). Beyond doubt he would have prolonged deliberation till his hundred-and-first; and they would be infallibly and invincibly wrong. This is what always happens to the deliberations of a simple man who thinks he is a subtle one.

We vainly accuse the fury of guns, and the new inventions of death; it is in the power of every hand to destroy us, and we are beholden unto every one we meet he doth not kill us.

"For I am holy." When I hear these words I recognize the voice of the Saviour. But shall I take away my own? Certainly when He speaks thus He speaks in inseparable union with His body. But can I say, "I am holy"? If I mean a holiness that I have not received, I should be proud and a liar; but if I mean a holiness that I have received - as it is written: "Be ye holy because I the Lord your God am holy" (Lev. 19:2) - then let the body of Christ say these words. And let this one man, who cries from the ends of the earth, say with his Head and united with his Head: "I am holy." … That is not foolish pride, but an expression of gratitude. If you were to say that you are holy of yourselves, that would be pride; but if, as one of Christ's faithful and as a member of Christ, you say that you are not holy, you are ungrateful.

There is a word very commonly used these days: "anti-communism." It's a very stupid word, badly put together. It makes it appear as though communism were something original, something basic, something fundamental. Therefore, it is taken as the point of departure, and anti-communism is defined in relation to communism. Here is why I say that this word was poorly selected, that it was put together by people who do not understand etymology: the primary, the eternal concept is humanity. And communism is anti-humanity. Whoever says "anti-communism" is saying, in effect, anti-anti-humanity. A poor construction. So we should say: that which is against communism is for humanity. Not to accept, to reject this inhuman Communist ideology is simply to be a human being. It isn't being a member of a party.

When I happen to be satisfied with everything, even God and myself, I immediately react like the man who, on a brilliant day, torments himself because the sun is bound to explode in a few billion years.

Historians of ideas, however scrupulous and minute they may feel it necessary to be, cannot avoid perceiving their material in terms of some kind of pattern.

I have tried to set forth a theory that enables us to understand and to assess these feelings about the primacy of justice. Justice as fairness is the outcome: it articulates these opinions and supports their general tendency.

No one has the right to obey.

Even when labor is subjugated by capital it always necessarily maintains its own autonomy, and this ever more clearly true today with respect to the new immaterial, cooperative and collaborative forms of labor. This relationship is not isolated to the economic terrain but, as we will argue later, spills over into the biopolitical terrain of society as a hole, including military conflicts. In any case, we should recognize here that even in asymmetrical conflicts victory in terms of complete domination is not possible. All that can be achieved is a provisional and limited maintenance of control and order that must constantly be policed and preserved. Counterinsurgency is a full-time job.

All these present struggles revolve around the question: Who are we? They are a refusal of these abstractions, of economic and ideological state violence, which ignore who we are individually, and also a refusal of a scientific or administrative inquisition which determines who one is.

So dazzling was the spread of constellations that it had the impact of a vision, of some hidden insight. I drove home saying to myself: The dead, too, are like this, blazing within us - invisibly.

How can a rational being be ennobled by anything that is not obtained by its own exertions?

Becoming a vegetarian is not merely a symbolic gesture. Nor is it an attempt to isolate oneself from the ugly realities of the world, to keep oneself pure and so without responsibility for the cruelty and carnage all around. Becoming a vegetarian is a highly practical and effective step one can take toward ending both the killing of nonhuman animals and the infliction of suffering upon them.

It is clear that thought is not free if the profession of certain opinions makes it impossible to earn a living. It is clear also that thought is not free if all the arguments on one side of a controversy are perpetually presented as attractively as possible, while the arguments on the other side can only be discovered by diligent search.

We were ensnared by the wisdom of the serpent; we are set free by the foolishness of God.

The power of thought is the light of knowledge, the power of will is the energy of character, the power of heart is love. Reason, love and power of will are perfections of man.

An observer studying the Solar system dispassionately, and finding himself capable of bringing the four giant planets to his notice, could reasonably say that the Solar system consisted of one star, four planets, and some traces of debris.

By awakening the Heroic that slumbers in every heart, can any Religion gain followers.

Those who promise us paradise on earth never produced anything but a hell.

The good seed that nature plants in us is so slight and so slippery that it cannot withstand the least harm from wrong nourishment.

I live in the Managerial Age, in a world of "Admin." The greatest evil is not now done in those sordid "dens of crime" that Dickens loved to paint. It is not done even in concentration camps and labour camps. In those we see its final result. But it is conceived and ordered (moved, seconded, carried, and minuted) in clean, carpeted, warmed, and well-lighted offices, by quiet men with white collars and cut fingernails and smooth-shaven cheeks who do not need to raise their voice. Hence, naturally enough, my symbol for Hell is something like the bureaucracy of a police state or the offices of a thoroughly nasty business concern.

For if a thing is not diminished by being shared with others, it is not rightly owned if it is only owned and not shared.

Many agnostics (including myself) are quite as doubtful of the body as they are of the soul, but this is a long story taking one into difficult metaphysics. Mind and matter alike, I should say, are only convenient symbol in discourse, not actually existing things.

A utopia of judicial reticence: take away life, but prevent the patient from feeling it; deprive the prisoner of all rights, but do not inflict pain; impose penalties free of all pain. Recourse to psycho-pharmacology and to various physiological 'disconnectors', even if it is temporary, is a logical consequence of this 'non-corporal' penalty.

Since the great foundation of fear is pain, the way to harden and fortify children against fear and danger is to accustom them to suffer pain. This 'tis possible will be thought, by kind parents, a very unnatural thing towards their children; and by most, unreasonable...

Nietzsche ... does not shy from conscious exaggeration and one-sided formulations of his thought, believing that in this way he can most clearly set in relief what in his vision and in his inquiry is different from the run-of-the-mill.
