The mind must be indulged, and leisure must be given from time to time, which is the place of food and strength.

But among all the discoveries and corrections probably none has resulted in a deeper influence on the human spirit than the doctrine of Copernicus.... Possibly mankind has never been demanded to do more, for considering all that went up in smoke as a result of realizing this change: a second Paradise, a world of innocence, poetry and piety: the witness of the senses, the conviction of a poetical and religious faith. No wonder his contemporaries did not wish to let all this go and offered every possible resistance to a doctrine which in its converts authorized and demanded a freedom of view and greatness of thought so far unknown indeed not even dreamed of.

The logical picture of the facts is the thought.

The world of our experience consists at all times of two parts, an objective and a subjective part, of which the former may be incalculably more extensive than the latter, and yet the latter can never be omitted or suppressed. The objective part is the sum total of whatsoever at any given time we may be thinking of, the subjective part is the inner "state" in which the thinking comes to pass.

At this point of his effort man stands face to face with the irrational. He feels within him his longing for happiness and for reason. The absurd is born of this confrontation between the human need and the unreasonable silence of the world. This must not be forgotten. This must be clung to because the whole consequence of a life can depend on it. The irrational, the human nostalgia, and the absurd that is born of their encounter, these are the three characters in the drama that must necessarily end with all the logic of which an existence is capable.

When I consider the short duration of my life, swallowed up in the eternity before and after, the small space which I fill, or even can see, engulfed in the infinite immensity of spaces whereof I know nothing, and which know nothing of me, I am terrified, and wonder that I am here rather than there, for there is no reason why here rather than there, or now rather than then. Who has set me here? By whose order and design have this place and time been destined for me? It is not well to be too much at liberty. It is not well to have all we want.How many kingdoms know nothing of us! The eternal silence of these infinite spaces alarms me.

I am ashamed of belonging to the species Homo Sapiens...You & I may be thankful to have lived in happier times - you more than I, because you have no children.

The principle of brotherhood expounded by the agitator of Nazareth preserved the germ of life, of truth and justice, so long as it was the beacon light of the few. The moment the majority seized upon it, that great principle became a shibboleth and harbinger of blood and fire, spreading suffering and disaster. The attack on the omnipotence of Rome was like a sunrise amid the darkness of the night, only so long as it was made by the colossal figures of a Huss, a Calvin, or a Luther. Yet when the mass joined in the procession against the Catholic monster, it was no less cruel, no less bloodthirsty than its enemy. Woe to the heretics, to the minority, who would not bow to its dicta. After infinite zeal, endurance, and sacrifice, the human mind is at last free from the religious phantom; the minority has gone on in pursuit of new conquests, and the majority is lagging behind, handicapped by truth grown false with age.

The first task of administrative theory is to develop a set of concepts that will permit the description, in terms relevant to the theory, of administrative situations. These concepts, to be scientifically useful, must be operational; that is, their meanings must correspond to empirically observable facts or situations.

The man of virtue makes the difficulty to be overcome his first business, and success only a subsequent consideration.

I believe in intuition and inspiration. ... At times I feel certain I am right while not knowing the reason. When the eclipse of 1919 confirmed my intuition, I was not in the least surprised. In fact I would have been astonished had it turned out otherwise. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.

The actor's realm is that of the fleeting.

A terrible thing is intelligence. It tends to death as memory tends to stability. The living, the absolutely unstable, the absolutely individual, is strictly unintelligible. Logic tends to reduce everything to identities and genera, to each representation having no more than one self-same content in whatever place, time or relation it may occur to us. And there is nothing that remains for two successive moments of its existence. My idea of God is different each time that I conceive it. Identity, which is death, is the goal of the intellect. The mind seeks what is dead, for what is living escapes it; it seeks to congeal the flowing stream in blocks of ice; it seeks to arrest it. In order to analyze a body it is necessary to extenuate or destroy it. In order to understand anything it is necessary to kill it, to lay it out rigid in the mind.

The most manifest sign of wisdom is a continual cheerfulness; her state is like that in the regions above the moon, always clear and serene.

There is but One Principle that proceeds from God; and thus, in consequence of the unity of the Power, it is possible for each Individual to schematise his World of Sense in accordance with the law of that original harmony; - and every Individual, under the condition of being found on the way towards the recognition of the Imperative, must so schematise it. I might say: - Every Individual can and must, under the given condition, construct the True World of Sense, - for this indeed has beyond the universal and formal laws above deduced, no other Truth and Reality than this universal harmony.

Our present-day neurochemical cocktail, we are asked to believe, is the medium through which alien realms of consciousness can be grasped and neutrally appraised from a third-person perspective. Empirical research suggests this optimism is at best naïve.

All this of Liberty and Equality, Electoral suffrages, Independence and so forth, we will take, therefore, to be a temporary phenomenon, by no means a final one. Though likely to last a long time, with sad enough embroilments for us all, we must welcome it, as the penalty of sins that are past, the pledge of inestimable benefits that are coming.

Subjects who reciprocally recognize each other as such, must consider each other as identical, insofar as they both take up the position of subject; they must at all times subsume themselves and the other under the same category. At the same time, the relation of reciprocity of recognition demands the non-identity of one and the other, both must also maintain their absolute difference, for to be a subject implies the claim of individuation.

The key to understanding Crowley is the same as the key to understanding the Marquis de Sade. Both wasted an immense amount of energy screaming defiance at the authority they resented so much, and lacked the insight to see that they were shaking their fists at an abstraction.

I saw a Divine Being. I'm afraid I'm going to have to revise all my various books and opinions.

...out of the tomb of the murdered Monarchy in France, has arisen a vast, tremendous, unformed spectre, in a far more terrific guise than any which ever yet have overpowered the imagination and subdued the fortitude of man.

I once had a conversation with a famous French philosopher who's a friend of mine. And I said to him, "Why the hell do you write so badly? Pourquoi tu écris si mal?" ... And this was Michel Foucault. He was a very smart guy and wrote a lot of very good stuff but in general he just wrote badly. When you heard him give a lecture in Berkeley, it was perfectly clear, just as clear as I am. ... And he said, "Well, in France, it would be regarded as somewhat childish and naive if you wrote clearly. ... In France you've got to have 10% incomprehensible."

It may be expedient but it is not just that some should have less in order that others may prosper.

Being is continuous becoming.

Man is as much a slave to his immediate surroundings now as he was when he lived in tree-huts. Give him the highest, the most exciting thoughts about man's place in the universe, the meaning of history; they can all be snuffed out in a moment if he wants his dinner, or feels irritated by a child squalling on a bus. He is bound by pettiness.

I hold in fact(1) That small portions of space are in fact of a nature analogous to little hills on a surface which is on the average flat; namely, that the ordinary laws of geometry are not valid in them.(2) That this property of being curved or distorted is continually being passed on from one portion of space to another after the manner of a wave.(3) That this variation of the curvature of space is what really happens in that phenomenon which we call the motion of matter, whether ponderable or etherial.(4) That in the physical world nothing else takes place but this variation, subject possibly to the law of continuity.

We live invested in an electric information environment that is quite as imperceptible to us as water is to fish.

A man should build a house with his own hands before he calls himself an engineer.

In the old dramas it was love that had to be sacrificed to painful duty. In the modern instance the sacrifice is at the shrine of what William James called "the Bitch Goddess, Success." Love is to be abandoned for the stern pursuit of newspaper notoriety and dollars.

The essence of the Liberal outlook lies not in what opinions are held, but in how they are held: instead of being held dogmatically, they are held tentatively, and with a consciousness that new evidence may at any moment lead to their abandonment.

Enjoying things which are pleasant; that is not the evil: it is the reducing of our moral self to slavery by them that is.

Whatever moral rules you have deliberately proposed to yourself abide by them as they were laws, and as if you would be guilty of impiety by violating any of them. Don't regard what anyone says of you, for this, after all, is no concern of yours. How long, then, will you put off thinking yourself worthy of the highest improvements and follow the distinctions of reason? You have received the philosophical theorems, with which you ought to be familiar, and you have been familiar with them. What other master, then, do you wait for, to throw upon that the delay of reforming yourself?... Let whatever appears to be the best be to you an inviolable law.

To speak frankly, the family bond in the civilizee regime' causes fathers to desire the death of their children and children to desire the death of their fathers.

Were I a nightingale, I would act the part of a nightingale; were I a swan, the part of a swan.

Experience is what you get while looking for something else.

But since he has decided to have the impossibility of living, every misfortune is an opportunity which lays this importance of living before his eyes and obliges him to decide, once again, to die.

The Cry within me is a call to arms. It shouts: "I, the Cry, am the Lord your God! I am not an asylum. I am not hope and a home. I am not the Father nor the Son nor the Holy Ghost. I am your General! "You are not my slave, nor a plaything in my hands. You are not my friend, you are not my child. You are my comrade-in-arms! "Hold courageously the passes which I entrusted to you; do not betray them. You are in duty bound, and you may act heroically by remaining at your own battle station. "Love danger. What is most difficult? That is what I want! Which road should you take? The most craggy ascent! It is the one I also take: follow me!

Faced with information overload, we have no alternative but pattern-recognition.

Manufacture was all the time sheltered by protective duties in the hoe market, by monopolies in the colonial market, and broad as much as possible by differential duties.

Naturalism is a word of many meetings in philosophy as well as in art. like most isms - classicism and romanticism, idealism and realism in art - it's has become an emotional term, a war cry of partisans.

Upper middle-class upbringing has rooted out any element of what might appear to be self-assertion or egoism; good manners is to be like everyone else. So the male of the species becomes accustomed to suppress any stirring of impatience or originality. Shaw once said you can't learn to skate without making a fool of yourself; the British middle-class attitude seems to be that, in that case, you hadn't better skate at all. The result seems to be considerably more oppressive than being brought up in a Jewish ghetto or a west side slum.

He who remembers the evils he has undergone, and those that have threatened him, and the slight causes that have changed him from one state to another, prepares himself in that way for future changes and for recognizing his condition. The life of Caesar has no more to show us than our own; an emperor's or an ordinary man's, it is still a life subject to all human accidents.

The vitality of thought is in adventure. Ideas won't keep. Something must be done about them. When the idea is new, its custodians have fervor, live for it, and, if need be, die for it.

Whoever will be free must make himself free. Freedom is no fairy gift to fall into a man's lap. What is freedom? To have the will to be responsible for one's self.

Nay, number (itself) in armies, importeth not much, where the people is of weak courage; for (as Virgil saith) it never troubles the wolf how many the sheep be.

In America, more than anywhere else, the individual is lost in the achievements of the many. America is beginning to be the world leader in a scientific investigation. American scholarship is both patient and inspiring. The Americans show an unselfish devotion to science, which is the very opposite of the conventional European view of your countrymen. Too many of us look upon Americans as dollar chasers. This is a cruel libel, even if it is reiterated thoughtlessly by the Americans themselves. It is not true that the dollar is an American fetish. The American student is not interested in dollars, not even in success as such, but in his task, the object of the search. It is his painstaking application to the study of the infinitely little and the infinitely large which accounts for his success in astronomy.

All philosophers should end their days at Pythia's feet. There is only one philosophy, that of unique moments.

I had always hoped that the younger generation receiving their early impressions after the flame of liberty had been kindled in every breast, & had become as it were the vital spirit of every American, that the generous temperament of youth, analogous to the motion of their blood, and above the suggestions of avarice, would have sympathized with oppression wherever found, and proved their love of liberty beyond their own share of it.
