Jean-Paul Sartre, Existentialism and Human Emotions

"Existentialism's first move is to make every man aware of what he is and to make the full responsibility of his existence rest on him."

"I can always choose, but I ought to know that if I do not choose, I am still choosing."

"[E]very man ought to say to himself, "Am I really the kind of man who has the right to act in such a way that humanity might guide itself by my actions?"
