Existence precedes and commands essence.
Existence is not something which lets itself be thought of from a distance: it must invade you suddenly, master you, weigh heavily on your heart like a great motionless beast – or else there is nothing more at all.
Existence as determinate being is in essence being for another.

Every existence has its idiom, every thing has an idiom and tongue.
Certain faults are necessary to the individual if he is to exist.
As far as we can discern, the sole purpose of human existence is to kindle a light of meaning in the darkness of mere being.
Art, at least, teaches us that man cannot be explained by history alone and that he also finds a reason for his existence in the order of nature.
All moments, past, present, and future, always have existed, always will exist.
A nihilist is not one who believes in nothing, but one who does not believe in what exists.
