To forget about the others? How utterly absurd! I feel you there, in every pore. Your silence clamors in my ears. You can nail up your mouth, cut you… - Jean-Paul Sartre

No doctrine is more optimistic [than existentialism], since it declares that man's destiny lies within himself.

"When I was little, my Aunt Bigeois told me "If you look at yourself too long in the mirror, you'll see a monkey." I must have looked at myself even longer than that: what I see is well below the monkey, on the fringe of the vegetable world, at the level of jellyfish... The eyes especially are horrible seen so close. They are glassy, soft, blind, red-rimmed, they look like fish scales... A silky white down covers the great slopes of the cheeks, two hairs protrude from the nostrils: it is a geological embossed map. And, in spite of everything, this lunar world is familiar to me. I cannot say I recognize the details. But the whole thing gives me an impression of something seen before which stupefies me."

we are abandoned in the world ... in the sense that we find ourselves suddenly alone and without help. Man is condemned to be free; because once thrown into the world, he is responsible for everything he does.
