If it were art to overcome heresy with fire, the executioners would be the most learned doctors on earth.

Life is possible only by the deficiencies of our imagination and memory.

In sum, a theory is only accepted if the theory has substantial, non-ad hoc, explanatory successes. This is in accordance with Popper; unfortunately, it is in even better accordance with the 'inductivist' accounts that Popper rejects, since these stress support rather than falsification.

When we observe a thing, we see too much in it, we fall under the spell of the wealth of empirical detail which prevents us from clearly perceiving the notional determination which forms the core of the thing. The problem is thus not that of how to grasp the multiplicity of determinations, but rather to abstract from them, how to constrain our gaze and teach it to grasp only the notional determinism.

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

In order to abolish the idea of private property, the idea of communism is completely sufficient. It takes actual communist action to abolish actual private property. History will com to it; and this movement, which in theory we already know to be a self-transcending movement, will constitute in actual fact a very severe and protracted process. But we must regard it as a real advance to have gained beforehand a consciousness of the limited character a well as of the goal of this historical movement - and a consciousness which reaches out beyond it.

On our earth we can only love with suffering and through suffering. We cannot love otherwise, and we know of no other sort of love. I want suffering in order to love. I long, I thirst, this very instant, to kiss with tears the earth that I have left, and I don't want, I won't accept life on any other!"

The history of the American kings of capital and authority is the history of repeated crimes, injustice, oppression, outrage, and abuse, all aiming at the suppression of individual liberties and the exploitation of the people. A vast country, rich enough to supply all her children with all possible comforts, and insure well-being to all, is in the hands of a few, while the nameless millions are at the mercy of ruthless wealth gatherers, unscrupulous lawmakers, and corrupt politicians.The reign of these kings is holding mankind in slavery, perpetuating poverty and disease, maintaining crime and corruption; it is fettering the spirit of liberty, throttling the voice of justice, and degrading and oppressing humanity. It is engaged in continual war and slaughter, devastating the country and destroying the best and finest qualities of man; it nurtures superstition and ignorance, sows prejudice and strife, and turns the human family into a camp of Ishmaelites.

In all affairs - love, religion, politics, or business - it's a healthy idea, now and then, to hang a question mark on the things you have long taken for granted.

Without the aid of trained emotions the intellect is powerless against the animal organism. I had sooner play cards against a man who was quite skeptical about ethics, but bred to believe that 'a gentleman does not cheat,' than against an irreproachable moral philosopher who had been brought up among sharpers. In battle it is not syllogisms that will keep the reluctant nerves and muscles to their post in the third hour of the bombardment.

In a head-on clash between violence and power, the outcome is hardly in doubt. Nowhere is the self-defeating factor in the victory of violence over power more evident than in the use of terror to maintain domination, about whose weird successes and eventual failures we know perhaps more than any generation before us. Violence can destroy power; it is utterly incapable of creating it.

Old religious factions are volcanoes burnt out.

(On the Trinitarian indwelling personally experienced by Saint Augustine) But what is it that I love in loving You? Not corporeal beauty, nor the splendour of time, nor the radiance of the light, so pleasant to our eyes, nor the sweet melodies of songs of all kinds, nor the fragrant smell of flowers, and ointments, and spices, not manna and honey, not limbs pleasant to the embracements of flesh. I love not these things when I love my God; and yet I love a certain kind of light, and sound, and fragrance, and food, and embracement in loving my God, who is the light, sound, fragrance, food, and embracement of my inner man — where that light shines unto my soul which no place can contain, where that sounds which time snatches not away, where there is a fragrance which no breeze disperses, where there is a food which no eating can diminish, and where that clings which no satiety can sunder. This is what I love, when I love my God.

The superior man has neither anxiety nor fear. When internal examination discovers nothing wrong, what is there to be anxious about, what is there to fear?

Free in this world as the birds in the air, disengaged from every kind of chains, those who have practiced the Yoga gather in Brahmin the certain fruit of their works. Depend upon it; rude and careless as I am, I would fain practice the yoga faithfully. This Yogi, absorbed in contemplation, contributes in his degree to creation; he breathes a divine perfume, he heard wonderful things. Divine forms traverse him without tearing him and he goes, he acts as animating original matter. To some extent, and at rare intervals, even I am a Yogi.

Maslow explained that, some time in the late thirties, he had been struck by the thought that modern psychology is based on the study of sick people. But since there are more healthy people around than sick people, how can this psychology give a fair idea of the workings of the human mind? It struck him that it might be worthwhile to devote some time to the study of healthy people.

Reaching and understanding is the process of bringing about an agreement on the presupposed basis of validity claims that are mutually recognized.

Ambition is a drug that makes its addicts potential madmen.

Animals are rational; in most of them logos is imperfect, but it is certainly not wholly lacking. So if, as our opponents say, justice applies to rational beings, why should not justice, for us, also apply to animals?

I could show, that the same faction has, in one reign, promoted popular seditions, and, in the next, been a patron of tyranny; I could show, that they have all of them betrayed the public safety at all times, and have very frequently with equal perfidy made a market of their own cause, and their own associates. I could show how vehemently they have contended for names, and how silently they have passed over things of the last importance.

One cannot too soon forget his errors and misdemeanors. To dwell long upon them is to add to the offense. Repentance and sorrow can only be displaced by something better, which is as free and original as if they had not been.

Needs must it be hard, since it is so seldom found. How would it be possible, if salvation were ready to our hand, and could without great labour be found, that it should be by almost all men neglected? But all things excellent are as difficult as they are rare.

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

Anger is a momentary madness so control your passion or it will control you.

The only thing that will redeem mankind is co-operation, and the first step towards co-operation lies in the hearts of individuals.

Only a male intellect clouded by the sexual drive could call the stunted, narrow-shouldered, broad-hipped and short-legged sex the fair sex.

If the ability to tell right from wrong should turn out to have anything to do with the ability to think, then we must be able to "demand" its exercise from every sane person, no matter how erudite or ignorant, intelligent or stupid, he may happen to be. Kant-in this respect almost alone among the philosophers-was much bothered by the common opinion that philosophy is only for the few, precisely because of its moral implications.

Pure mathematics is religion.

The Interpretation of the Laws of Nature in a Common-wealth, dependeth not on the books of Moral Philosophy. The Authority of writers, without the Authority of the Commonwealth, maketh not their opinions Law, be they never so true.

Virtuous men alone possess friends.

The labour-power is a commodity, not capital, in the hands of the labourer, and it constitutes for him a revenue so long as he can continuously repeat its sale; it functions as capital after its sale, in the hands of the capitalist, during the process of production itself.

Keep the faculty of effort alive in you by a little gratuitous exercise every day. That is, be systematically ascetic or heroic in little unnecessary points, do every day or two something for no other reason than that you would rather not do it, so that when the hour of dire need draws nigh, it may find you not unnerved and untrained to stand the test. So with the man who has daily inured himself to habits of concentrated attention, energetic volition, and self-denial in unnecessary things. He will stand like a tower when everything rocks around him, and when his softer fellow-mortals are winnowed like chaff in the blast.

Friendship, I have said, is born at the moment when one man says to another "What! You too? I thought that no one but myself..."

Every intellectual effort sets us apart from the commonplace, and leads us by hidden and difficult paths to secluded spots where we find ourselves amid unaccustomed thoughts.

The most perfect philosophy of the natural kind only staves off our ignorance a little longer: as perhaps the most perfect philosophy of the moral or metaphysical kind serves only to discover larger portions of it. Thus the observation of human blindness and weakness is the result of all philosophy, and meets us at every turn, in spite of our endeavours to elude or avoid it.

The whole mystery of commodities, all the magic and necromancy that surrounds the products of labor as long as they take the form of commodities, vanishes therefore, so soon as we come to other forms of production.

If you are not already dead, forgive. Rancor is heavy, it is worldly; leave it on earth: die light.

At the end of Being and Nothingness, ... Being in-itself and Being for-itself were of Being; and this totality of beings, in which they were effected, itself was linked up to itself, relating and appearing to itself, by means of the essential project of human-reality. What was named in this way, in an allegedly neutral and undetermined way, was nothing other than the metaphysical unity of man and God, the relation of man to God, the project of becoming God as the project constituting human-reality. Atheism changes nothing in this fundamental structure.

Isolation is the worst possible counselor.

Nor is there any embarrassment in the fact that we're ridiculous, isn't it true? For it's actually so, we are ridiculous, light-minded, with bad habits, we're bored, we don't know how to look, how to understand, we're all like that, all, you, and I, and they! Now, you're not offended when I tell you to your face that you're ridiculous? And if so, aren't you material? You know, in my opinion it's sometimes even good to be ridiculous, if not better: we can the sooner forgive each other, the sooner humble ourselves; we can't understand everything at once, we can't start right out with perfection! To achieve perfection, one must first begin by not understanding many things! And if we understand too quickly, we may not understand well. This I tell you, you, who have already been able to understand. .. and not understand ... so much. I'm not afraid for you now.

If, when a man writes a poem or commits a murder, the bodily movements involved in his act result solely from physical causes, it would seem absurd to put up a statue to him in the one case and to hang him in the other.

A word is a bud attempting to become a twig. How can one not dream while writing? It is the pen which dreams. The blank page gives the right to dream.

There is a physical relation between physical things. But it is different with commodities.

In brief, it is my thesis that human misery is the most urgent problem of a rational public policy and that happiness is not such a problem.

The new education must consist essentially in this, that it completely destroys freedom of will in the soil which it undertakes to cultivate, and produces on the contrary strict necessity in the decisions of the will, the opposite being impossible. Such a will can henceforth be relied on with confidence and certainty.

The woman who fights against her father still has the possibility of leading an instinctive, feminine existence, because she rejects only what is alien to her. But when she fights against the mother she may, at the risk of injury to her instincts, attain to greater consciousness, because in repudiating the mother she repudiates all that is obscure, instinctive, ambiguous, and unconscious in her own nature.

Whatever is known to us by consciousness, is known beyond possibility of question. What one sees or feels, whether bodily or mentally, one cannot but be sure that one sees or feels. No science is required for the purpose of establishing such truths; no rules of art can render our knowledge of them more certain than it is in itself. There is no logic for this portion of our knowledge.

Human knowledge and human power meet in one; for where the cause is not known the effect cannot be produced. Nature to be commanded must be obeyed; and that which in contemplation is as the cause is in operation as the rule.

The absurd ... is an experience to be lived through, a point of departure, the equivalent, in existence of Descartes' methodical doubt. Absurdism, like methodical doubt, has wiped the slate clean. It leaves us in a blind alley. But, like methodical doubt, it can, by returning upon itself, open up a new field of investigation, and in the process of reasoning then pursues the same course. I proclaim that I believe in nothing and that everything is absurd, but I cannot doubt the validity of my proclamation and I must at least believe in my protest. The first and only evidence that is supplied me, within the terms of the absurdist experience, is rebellion ... Rebellion is born of the spectacle of irrationality, confronted with an unjust and incomprehensible condition.
