Who can exhaust a man? Who knows a man's resources?

Listen to me: a family man is never a real family man. An assassin is never entirely assassin. They play a role, you understand. While a dead man, he is really dead. To be or not to be, right?

Ideas come in pairs and they contradict one another; their opposition is the principal engine of reflection.

Existence is not something which lets itself be thought of form a distance; it must invade you suddenly, master you, weigh heavily on your heart like a great motionless beast - or else there is nothing at all.

Don't you feel the same way? When I cannot see myself, even though I touch myself, I wonder if I really exist.

Man is nothing else but what he makes of himself.

What do we mean by saying that existence precedes essence? We mean that man first of all exists, encounters himself, surges up in the world-and defines himself afterward.
