“Doubt as sin. — Christianity has done its utmost to close the circle and declared even doubt to be sin. One is supposed to be cast into belief without reason, by a miracle, and from then on to swim in it as in the brightest and least ambiguous of elements: even a glance towards land, even the thought that one perhaps exists for something else as well as swimming, even the slightest impulse of our amphibious nature — is sin! And notice that all this means that the foundation of belief and all reflection on its origin is likewise excluded as sinful. What is wanted are blindness and intoxication and an eternal song over the waves in which reason has drowned.”

“...wherever the strength of a faith steps decisively into the foreground, we infer a certain weakness in its ability to demonstrate its truth, even the improbability of what it believes. We, too, do not deny that the belief “makes blessed,” but for that very reason we deny that the belief proves something—a strong belief which confers blessedness creates doubts about what it has faith in. It does not ground “truth.” It grounds a certain probability— delusion.”

“I beseech you, my brothers, remain faithful to the earth, and do not believe those who speak to you of otherworldly hopes! Poison-mixers are they, whether they know it or not. Despisers of life are they, decaying and poisoned themselves, of whom the earth is weary: so let them go. Once the sin against God was the greatest sin; but God died, and these sinners died with him. To sin against the earth is now the most dreadful thing, and to esteem the entrails of the unknowable higher than the meaning of the earth... What is the greatest experience you can have? It is the hour of the great contempt. The hour when your happiness, too, arouses your disgust, and even your reason and your virtue.”

“This eternal accusation against Christianity I shall write upon all walls, wherever walls are to be found--I have letters that even the blind will be able to see. . . . I call Christianity the one great curse, the one great intrinsic depravity, the one great instinct of revenge, for which no means are venomous enough, or secret, subterranean and small enough,--I call it the one immortal blemish upon the human race...”

“A degree of culture, and assuredly a very high one, is attained when man rises above superstitions and religious notions and fears, and, for instance, no longer believes in guardian angels or in original sin, and has also ceased to talk of the salvation of his soul.”

“...For action has no sense. It merely binds one to existence. All existence, however, has no sense. Evil is interpreted as that which leads to irrationalism: to the affirmation of means whose end is denied. A road to nonentity is the desideratum, hence all emotional impulses are regarded with horror.”

“But how can we venture to reprove or praise the universe! Let us beware of attributing to it heartlessness and unreason or their opposites: it is neither perfect nor beautiful nor noble, and has no desire to become any of these; it is by no means striving to imitate mankind! It is quite impervious to all our aesthetic and moral judgments! It has likewise no impulse to self-preservation or impulses of any kind; neither does it know any laws. Let us beware of saying there are laws in nature. There are only necessities: there is no one to command, no one to obey, no one to transgress...”
