Existentialism is nothing else but an attempt to draw the full conclusions from a consistently atheistic position. Its intention is not in the least … - Jean-Paul Sartre

Existentialism is not atheist in the sense that it would exhaust itself in demonstrations of the non-existence of God. It declares, rather, that even if God existed that would make no difference from its point of view. Not that we believe God does exist, but we think that the real problem is not that of His existence; what man needs is to find himself again and to understand that nothing can save him from himself, not even a valid proof of the existence of God.

Nothingness lies coiled in the heart of being - like a worm.

İnsan, insanlara var olmadıklarını inandırmak için bir felsefe incelemesine güvenemezdi. Bunun bir eylem olması gerekiyordu, gerçekten öylesine umutsuz bir eylem ki görüntüleri silsin götürsündü ve dünyanın hiçliğini gün ışığına göstersindi.
Bir patlama, kan içinde genç bir beden halının üstünde, bir kağıda yazılmış sözcükler: Kendimi öldürüyorum, çünkü var değilim. Ve siz de insan kardeşlerim, hiçsiniz!

"A circle is not absurd, it is clearly explained by the rotation of a straight segment around one of its extremities. But neither does a circle exist. This root, on the other hand, existed in such a way that I could not explain it. Knotty, inert, nameless, it fascinated me, filled my eyes, brought me back unceasingly to its own existence. In vain to repeat: "This is a root" — it didn't work any more. I saw clearly that you could not pass from its function as a root, as a breathing pump, to that, to this hard and compact skin of a sea lion, to this oily, callous, headstrong look. The function explained nothing: it allowed you to understand generally that it was a root, but not that one at all. This root, with its colour, shape, its congealed movement, was . . . below all explanation. Each of its qualities escaped it a little, flowed out of it, half solidified, almost became a thing; each one was In the way in the root and the whole stump now gave me the impression of unwinding itself a little, denying its existence to lose itself in a frenzied excess."
