"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… - Jean-Paul Sartre

"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."
