Consciousness is a being the nature of which is to be conscious of the nothingness of its being.
Jean-Paul SartreEvil is the product of the ability of humans to make abstract that which is concrete.
Jean-Paul Sartre[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.
