“Against the censurers of brevity. - Something said briefly can be the fruit of much long thought: but the reader who is a novice in this field, and has as yet reflected on it not at all, sees in everything said briefly something embryonic, not without censuring the author for having served him up such immature and unripened fare.”

“What is life? Life - that is: continually shedding something that wants to die. Life - that is: being cruel and inexorable against everything about us that is growing old and weak -and not only about us. Life - that is, then: being without reverence for those who are dying, who are wretched, who are ancient? Constantly being a murderer? -And yet old Moses said: "Thou shalt not kill.”

“Writers whose thoughts are expressed with clarity and precision are assumed by readers to be superficial. Where the meaning is obscured, then readers give more attention and consider the fruit of their labour more valuable”

“I know my fate. One day my name will be associated with the memory of something tremendous — a crisis without equal on earth, the most profound collision of conscience, a decision that was conjured up against everything that had been believed, demanded, hallowed so far. I am no man, I am dynamite.”

“As long as a man knows very well the strength and weaknesses of his teaching, his art, his religion, its power is still slight. The pupil and apostle who, blinded by the authority of the master and by the piety he feels toward him, pays no attention to the weaknesses of a teaching, a religion, and soon usually has for that reason more power than the master. The influence of a man has never yet grown great without his blind pupils. To help a perception to achieve victory often means merely to unite it with stupidity so intimately that the weight of the latter also enforces the victory of the former.”

“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.”

“A thinker sees his own actions as experiments and questions--as attempts to find out something. Success and failure are for him answers above all.”
