“It is a terrible thought, to contemplate that an immense number of mediocre thinkers are occupied with really influential matters.”

“I am too inquisitive, too skeptical, too arrogant, to let myself be satisfied with an obvious and crass solution of things. God is such an obvious and crass solution; a solution which is a sheer indelicacy to us thinkers - at bottom He is really nothing but a coarse commandment against us: ye shall not think! ”

“A thought comes when it will, not when I will.”

“A thought, even a possibility, can shatter and transform us.”

“Of all the evil I deem you capable. Therefore I want the good from you. Verily I have often laughed at weaklings who thought themselves good because they had no claws.”

“I go into solitude so as not to drink out of everybody's cistern. When I am among the many I live as the many do, and I do not think I really think. After a time it always seems as if they want to banish my self from myself and rob me of my soul.”

“What if, some day or night, a demon were to steal after you in your loneliest loneliness and say to you: “This life as you now live it and have lived it, you will have to live once more and innumerable times more; and there will be nothing new in it, but every pain and every joy and every thought and sigh and everything unutterably small or great in your life will have to return to you, all in the same succession and sequence—even this spider and this moonlight between the trees, and even this moment and I myself. The eternal hourglass of existence is turned upside down again and again—and you with it, speck of dust!”... Would you not throw yourself down and gnash your teeth and curse the demon who spoke thus? Or have you once experienced a tremendous moment when you would have answered him: 'You are a god and never have I heard anything more divine.”
