Or, as Sartre said, "existence precedes essence". That's the crux of Existentialism. But does that mean that if we find no essence/meaning, we should feel liberated to call it quits?
Well, for Sartre essence or facticity is basically everything that doesn't include consciousness. So, we all necessarily have "essence", and our past counts as part of that essence, or being-in-itself. I'm not sure I understand.
