For the secret of man's being is not only to live but to have something to live for. Without a stable conception of the object of life, man would not consent to go on living, and would rather destroy himself than remain on earth, though he had bread in abundance.
Above all, avoid falsehood, every kind of falsehood, especially falseness to yourself. Watch over your own deceitfulness and look into it every hour, every minute.
I wanted to pray for an hour, but I keep thinking and thinking, and always sick thoughts, and my head aches - what is the use of praying? - it's only a sin! It is strange, too, that I am not sleepy: in great, too great sorrow, after the first outbursts one is always sleepy. Men condemned to death, they say, sleep very soundly on the last night.

... the more I learned, the more conscious did I become of the fact that I was ridiculous. So that for me my years of hard work at the university seem in the end to have existed for the sole purpose of demonstrating and proving to me, the more deeply engrossed I became in my studies, that I was an utterly absurd person
