Jean-Paul Charles Aymard Sartre (21 June 1905 – 15 April 1980), normally known simply as Jean-Paul Sartre, was a French existentialist philosopher, dramatist and screenwriter, novelist, and critic. He had an enduring personal relationship with fellow philosopher Simone de Beauvoir.
"So this is hell. I'd never have believed it. You remember all we were told about the torture-chambers, the fire and brimstone, the "burning marl." Old wives' tales! There's no need for red-hot pokers. Hell is — other people!"
I was not the one to invent lies: they were created in a society divided by class and each of us inherited lies when we were born. It is not by refusing to lie that we will abolish lies: it is by eradicating class by any means necessary.
Quietism is the attitude of people who say, "let others do what I cannot do." The doctrine I am presenting before you is precisely the opposite of this, since it declares that there is no reality except in action. It goes further, indeed, and adds, "Man is nothing else but what he purposes, he exists only in so far as he realizes himself, he is therefore nothing else but the sum of his actions, nothing else but what his life is." Hence we can well understand why some people are horrified by our teaching.
