“It may be that until now there has been no more potent means for beautifying man himself than piety: it can turn man into so much art, surface, play of colors, graciousness that his sight no longer makes one suffer.---”

“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.”

“I should like to direct the attention of artists. A constant producer, a man who is a "mother" in the grand sense of the term, one who no longer knows or hears of anything except pregnancies and childbeds of his spirit, who has no time at all to reflect and make comparisons with regard to himself and his work, who is also no longer inclined to exercise his taste, but simply forgets it, letting it take its chance of standing, lying or falling -- perhaps such a man at last produces works on which he is then quite unfit to pass a judgment: so that he speaks and thinks foolishly about them and about himself. This seems to me almost the normal condition with fruitful artists.”

“No one can draw more out of things, books included, than he already knows. A man has no ears for that to which experience has given him no access.”

“Ah, where in the world have there been greater follies than with the pitiful? And what in the world hath caused more suffering than the follies of the pitiful?Woe unto all loving ones who have not an elevation which is above their pity!Thus spake the devil unto me, once on a time: "Even God hath his hell: it is his love for man." And lately, did I hear him say these words: "God is dead: of his pity for man hath God died.”

“The maturity of man—that means, to have reacquired the seriousness that one had as a child at play”

“You have evolved from worm to man, but much within you is still worm. Once you were apes, yet even now man is more of an ape than any of the apes.”
