In framing scientific terms, the appropriation of old words is preferable to the invention of new ones.

Bigotry is the disease of ignorance, of morbid minds; enthusiasm of the free and buoyant. Education & free discussion are the antidotes of both.

As long as I can remember, I have suffered because of the great misery I saw in the world. I never really knew the artless, youthful joy of living, and I believe that many children feel this way, even when outwardly they seem to be wholly happy and without a single care.

Life has a value only when it has something valuable as its object.

The unity is brought about by force.

Whether nature gives me a right, or whether God, the people's choice, etc., does so, all of that is the same foreign right, a right that I do not give or take to myself. Thus the Communists say, equal labour entitles man to equal enjoyment. [...] No, equal labour does not entitle you to it, but equal enjoyment alone entitles you to equal enjoyment. Enjoy, then you are entitled to enjoyment. But, if you have laboured and let the enjoyment be taken from you, then - 'it serves you right.' If you take the enjoyment, it is your right; if, on the contrary, you only pine for it without laying hands on it, it remains as before, a, 'well-earned right' of those who are privileged for enjoyment. It is their right, as by laying hands on it would become your right.

Man in the electronic age has no possible environment except the globe and no possible occupation except information-gathering.

I'd rather be ruled by a competent Turk than an incompetent Christian.

Don Quixote made himself ridiculous; but did he know the most tragic ridicule of all, the inward ridicule, the ridiculousness of a man's self to himself, in the eyes of his own soul? Imagine Don Quixote's battlefield to be his own soul; imagine him to be fighting in his soul to save the Middle Ages from the Renaissance, to preserve the treasure of his infancy; imagine him an inward Don Quixote, with a Sancho at his side, inward and heroic too - and tell me if you find anything comic in the tragedy.

Atheism ... in its philosophic aspect refuses allegiance not merely to a definite concept of God, but it refuses all servitude to the God idea, and opposes the theistic principle as such. Gods in their individual function are not half as pernicious as the principle of theism which represents the belief in a supernatural, or even omnipotent, power to rule the earth and man upon it. It is the absolutism of theism, its pernicious influence upon humanity, its paralyzing effect upon thought and action, which Atheism is fighting with all its power.

Time is the soul of this world.

Everyone sits in the prison of his own ideas; he must burst it open, and that in his youth, and so try to test his ideas on reality.

The workers have the most enormous power in their hands, and if one day they became truly aware of it and used it, then nothing could resist them; they would only have to stop work and look upon the products of work as their own and enjoy them. This is the meaning of the labor unrest that is looming here and there. The state is founded on the-slavery of labor. If labor becomes free, the state is lost.

I know God only as he became human, so shall I have him in no other way.

Men reject their prophets and slay them, but they love their martyrs and honor those they have slain.

Too many of our preferences reflect nasty behaviours and states of mind that were genetically adaptive in the ancestral environment. Instead, wouldn't it be better if we rewrote our own corrupt code?

What if the equality between us human being, in which we completely resemble one another, were that none of us really thinks about his being loved?

Every body is in place; but nothing essentially incorporeal, or any thing of this kind, has any locality.

I had hoped that out of so many stories you would at least have produced one or two, which could hardly be questioned, and which would clearly show that ghosts or spectres exist. The case you relate... seems to me laughable. In like manner it would be tedious here to examine all the stories of people, who have written on these trifles. To be brief, I cite the instance of Julius Caesar, who, as Suetonius testifies, laughed at such things and yet was happy. ...And so should all who reflect on the human imagination, and the effects of the emotions, laugh at such notions; whatever Lavater and others, who have gone dreaming with him in the matter, may produce to the contrary.

Suffer it to be so now: for thus it becometh us to fulfil all righteousness.

The essential nature (concerning the soul) cannot be corporeal, yet it is also clear that this soul is present in a particular bodily part, and this one of the parts having control over the rest (heart).

The only good that I can see in the demonstration of the truth of "Spiritualism" is to furnish an additional argument against suicide. Better live a crossing-sweeper than die and be made to talk twaddle by a "medium" hired at a guinea a séance.

So rolling time changes the seasons of things. What was of value, becomes in turn of no worth.

The soul of wit may become the very body of untruth.

Persons who feel themselves to be exiles in this world-and what noble mind, from Empedocles down, has not had that feeling?-are mightily inclined to believe themselves citizens of another.

It is a serious thing to live in a society of possible gods and goddesses, to remember that the dullest most uninteresting person you talk to may one day be a creature which, if you saw it now, you would be strongly tempted to worship, or else a horror and a corruption such as you now meet, if at all, only in a nightmare. All day long we are, in some degree helping each other to one or the other of these destinations. It is in the light of these overwhelming possibilities, it is with the awe and the circumspection proper to them, that we should conduct all of our dealings with one another, all friendships, all loves, all play, all politics. There are no ordinary people. You have never talked to a mere mortal. Nations, cultures, arts, civilizations - these are mortal, and their life is to ours as the life of a gnat. But it is immortals whom we joke with, work with, marry, snub, and exploit - immortal horrors or everlasting splendors.

What I stand for is what I stand on.

There are clear cases in which "understanding" literally applies and clear cases in which it does not apply; and these two sorts of cases are all I need for this argument.

The most difficult thing in life is to know yourself.

My dear Kepler, what would you say of the learned here, who, replete with the pertinacity of the asp, have steadfastly refused to cast a glance through the telescope? What shall we make of this? Shall we laugh, or shall we cry?

The entire method consists in the order and arrangement of the things to which the mind's eye must turn so that we can discover some truth.

Do you believe in dreams, Uncle Simeon? I do; I believe in nothing else. One night I dreamed that invisible enemies had me tied to a dead cypress. Long red arrows were sticking into me from my head to my feet, and the blood was flowing. On my head they had placed a crown of thorns, and intertwined with the thorns were fiery letters which said: "Saint Blasphemer." I am Saint Blasphemer, Rabbi Simeon. So you'd better not ask me anything else, or I'll start my blasphemies.

Knowledge is the food of the soul; and we must take care, my friend, that the Sophist does not deceive us when he praises what he sells, like the dealers wholesale or retail who sell the food of the body; for they praise indiscriminately all their goods, without knowing what are really beneficial or hurtful.

The pre-atomist multisensory void was an animate, pulsating, and moving vibrant interval, neither container nor contained, acoustic space penetrated by tactility.

Scientific theories can always be improved and are improved. That is one of the glories of science. It is the authoritarian view of the Universe that is frozen in stone and cannot be changed, so that once it is wrong, it is wrong forever.

Take a book, the poorest one written, but read it with the passion that it is the only book you will read-ultimately you will read everything out of it, that is, as much as there was in yourself, and you could never get more out of reading, even if you read the best of books.

We hardly know any instance of the strength and weakness of human nature so striking, and so grotesque, as the character of this haughty, vigilant, resolute, sagacious blue-stocking, half Mithridates and half Trissotin, bearing up against a world in arms, with an ounce of poison in one pocket and a quire of bad verses in the other.

This is precisely what is decisive in Nietzsche's conception of art, that he sees it in its essential entirety in terms of the artist; this he does consciously and in explicit opposition to that conception of art which represents it in terms of those who "enjoy" and "experience" it.That is a guiding principle of Nietzsche's teaching on art: art must be grasped in terms of creators and producers, not recipients. Nietzsche expresses it unequivocally in the following words (WM, 811): "Our aesthetics heretofore has been a woman's aesthetics, inasmuch as only the recipients of art have formulated their experiences of 'what is beautiful.' In all philosophy to date the artist is missing." Philosophy of art means "aesthetics" for Nietzsche too-but masculine aesthetics, not feminine aesthetics. The question of art is the question of the artist as the productive, creative one; his experiences of what is beautiful must provide the standard.

Certainly He says this for me, for thee, for this other man, since He bears His body, the Church. Unless you imagine, brethren, that when He said: My Father, if it be possible, let this cup pass away from (Matt. 26:39), it was the Lord that feared to die. . . . But Paul longed to die, that he might be with Christ. What? The Apostle desires to die, and Christ Himself should fear death? What can this mean, except that He bore our infirmity in Himself, and uttered these words for those who are in His body and still fear death? It is from these that the voice came; it was the voice of His members, not of the Head. When He said, My soul is sorrowful unto death (Matt. 26:38), He manifested Himself in thee, and thee in Himself. And when He said, My God, my God, why has Thou forsaken Me? (Matt. 27:46), the words He uttered on the cross were not His own, but ours.

Adapt yourself to the environment in which your lot has been cast, and show true love to the fellow-mortals with whom destiny has surrounded you.

When it became obvious what a dumb and cruel and spiritually and financially and militarily ruinous mistake our war in Vietnam was, every artist worth a damn in this country, every serious writer, painter, stand-up comedian, musician, actor and actress, you name it, came out against the thing. We formed what might be described as a laser beam of protest, with everybody aimed in the same direction, focused and intense. This weapon proved to have the power of a banana-cream pie three feet in diameter when dropped from a stepladder five-feet high.

Guilt has to be understood not only as a way of checking one's own destructiveness, but as a mechanism for safeguarding the life of the other, one that emerges from our own need and dependency, from a sense that this life is not a life without another life. Indeed, when it turns into a safeguarding action, I am not sure it should still be called "guilt." If we do still use that term, we could conclude that "guilt" is strangely generative or that its productive form is reparation.

An imaginary perfection is automatically at the same level as I who imagine it - neither higher nor lower.

Go thy way; and as thou hast believed, so be it done unto thee.

Why should we divide the sensitive principle which thinks in man? ...For a thing that is divided can no longer without absurdity be regarded as indivisible.
