Man is condemned to be free; because once thrown into the world, he is responsible for everything he does.

It is therefore senseless to think of complaining since nothing foreign has decided what we feel, what we live, or what we are.

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.

As far as men go, it is not what they are that interests me, but what they can become.

The past is the luxury of proprietors.

Everything has been figured out, except how to live.

Il n'y a de réalité que dans l'action. (There is no reality except in action.)
