Never read a book to the end, nor even in sequence and without skipping.

No intelligent idea can gain general acceptance unless some stupidity is mixed in with it.

Should you ask me if I'm happy, I'll answer that I'm not.

Blessed are those who entrust their lives to no one.

I walk along a street and see in the faces of the passersby not the expression they really have but the expression they would have for me if they knew about my life and how I am, if I carried, transparent in my gestures and my face, the ridiculous, timid abnormality of my soul.

Never having discovered qualities in myself which could attract someone else, I could never believe that anyone felt attracted to me.

There is no happiness without knowledge. But knowledge of happiness is unhappy; for knowing ourselves happy is knowing ourselves passing through happiness, and having to, immediatly at once, leave it behind. To know is to kill, in happiness as in everything. Not to know, though, is not to exist.
