Life is nothing until it is lived; but it is yours to make sense of, and the of it is nothing other than the sense you choose.

Man is what he wills himself to be.

A madman's ravings are absurd in relation to the situation in which he finds himself, but not in relation to his madness.

Something begins in order to end: an adventure doesn't let itself be extended it achieves significance only through its death.

Existence precedes and rules essence.

One does not adopt a new idea, one slips into it.

I am beginning to believe that nothing can ever be proved. These are honest hypotheses which take the facts into account: but I sense so definitely that they come from me, and that they are simply a way of unifying my own knowledge. Not a glimmer comes from Rollebon's side. Slow, lazy, sulky, the facts adapt themselves to the rigour of the order I wish to give them; but it remains outside of them. I have the feeling of doing a work of pure imagination.
