“The bond between being and non-being can be only internal. It is within being qua being that non-being must arise, and within non-being that being must spring up; and this relation can not be a fact, a natural law, but an upsurge of the being which is its own nothingness of being.”

“Consciousness is a being the nature of which is to be conscious of the nothingness of its being.”

“Nothingness haunts Being.”

“Being is. Being is in-itself. Being is what it is.”

“I must be without remorse or regrets as I am without excuse; for from the instant of my upsurge into being, I carry the weight of the world by myself alone without help, engaged in a world for which I bear the whole responsibility without being able, whatever I do, to tear myself away from this responsibility for an instant.”

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

“Perhaps its inevitable, perhaps one has to choose between being nothing at all and impersonating what one is.”
