"I have crossed the seas, I have left cities behind me, and I have followed the source of rivers towards their source or plunged into forests, always making for other cities. I have had women, I have fought with men ; and I could never turn back any more than a record can spin in reverse. And all that was leading me where ? To this very moment."

What is meant here by saying that existence precedes essence? It means first of all, man exists, turns up, appears on the scene, and, only afterwards, defines himself. If man, as the existentialist conceives him, is indefinable, it is because at first he is nothing. Only afterward will he be something, and he himself will have made what he will be.
