Jean-Paul Sartre

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

Hell is other people.

We are our choices.

Existence precedes essence.

Man is a useless passion.

Everything is absurd.

Freedom is what you do with what's been done to you.

The essential thing is to not be afraid of being ridiculous.

Words are loaded pistols.

Every existing thing is born without reason, prolongs itself out of weakness, and dies by chance.

Man is a being who wills himself to be what he is not and wills not to be what he is.

Authenticity consists in the free and lucid assumption of the situation.

To be is to be there.

We are responsible for our passions.

The greatest joy lies in doing what others say you cannot do.

Man is a project which possesses a subjective existence.

Bad faith is a lie to oneself.

We must act without hope.

The individual is not born free, he becomes free.

If you are lonely when you're alone, you are in bad company.
