[M]an is condemned to be free. Condemned, because he did not create himself, in other respect is free; because, once thrown into the world, he is responsible for everything he does. The Existentialist does not believe in the power of passion. He will never agree that a sweeping passion is a ravaging torrent which fatally leads a man to certain acts and is therefore an excuse. He thinks that man is responsible for his passion.
Jean-Paul SartreTherefore, in the nature of this will for freedom, which freedom itself implies, I may pass judgement on those who seek to hide from themselves the complete arbitrariness and the complete freedom of their existence.
Jean-Paul SartreWhat never vary are the necessities of being in the world, of having to labor and to die there.
Jean-Paul Sartre
