"In that lucid moment I realized, too, that I was a blank fact, as empty and certain as a tautology, no less necessary, full of everything: I am I. Even if I am not Descartes and all this, too, is but a dream dreamt by someone else, I am then that other someone, that one, I am not nothing: I am the hollow nothing, in everything, I am you."
