“In his heart every man knows quite well that, being unique, he will be in the world only once and that no imaginable chance will for a second time gather together into a unity so strangely variegated an assortment as he is: he knows it but hides it like a bad conscience.”

“At bottom every man knows well enough that he is a unique being, only once on this earth; and by no extraordinary chance will such a marvelously picturesque piece of diversity in unity as he is, ever be put together a second time.”

“Even a man who makes the most modest pretensions to integrity must know that a theologian, a priest, a pope of today not only errs when he speaks, but actually lies—and that he no longer escapes blame for his lie through “innocence” or “ignorance.” The priest knows, as every one knows, that there is no longer any “God,”

“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.

“Ages of happiness. - An age of happiness is quite impossible, because men want only to desire it but not to have it, and every individual who experiences good times learns to downright pray for misery and disquietude. The destiny of man is designed for happy moments - every life has them - but not for happy ages. Nonetheless they will remain fixed in the imagination of man as 'the other side of the hill' because they have been inherited from ages past: for the concepts of the age of happiness was no doubt acquired in primeval times from that condition of which, after violent exertion in hunting and warfare, man gives himself up to repose, stretches his limbs and hears the pinions of sleep rustling about him. It is a false conclusion if, in accordance with that ancient familiar experience, man imagines that, after whole ages of toil and deprivation, he can then partake of that condition of happiness correspondingly enhanced and protracted.”
