Each of us, face to face with other men, is clothed with some sort of dignity, but we know only too well all the unspeakable things that go on in the heart.

We think we understand each other, but we never really do.

Whatever is a reality today, whatever you touch and believe in and that seems real for you today, is going to be - like the reality of yesterday - an illusion tomorrow.

Logic is one thing, the human animal another. You can quite easily propose a logical solution to something and at the same time hope in your heart of hearts it won't work out.

If only we could see in advance all the harm that can come from the good we think we are doing.

Man never reasons so much and becomes so introspective as when he suffers; since he is anxious to get at the cause of his sufferings, to learn who has produced them, and whether it is just or unjust that he should have to bear them.

Those who understood, in fact, say: 'I mustn't do this, I mustn't do that,' so as not to commit some stupidity or other! Splendid! But at a certain point we realize that all life is stupidity; so tell me yourself what it means never to have done anything foolish. At the very least it means you have never lived.
