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.
Jean-Paul SartreThen I realized what separated us: what I thought about him could not reach him; it was psychology, the kind they write about in books. But his judgment went through me like a sword and questioned my very right to exist. And it was true, I had always realized it; I hadn't the right to exist. I had appeared by chance, I existed like a stone, a plant or a microbe. My life put out feelers towards small pleasures in every direction. Sometimes it sent out vague signals; at other times I felt nothing more than a harmless buzzing.
