“If anything could prove the existence of the soul, he thought, it was the utter emptiness of a corpse.”

“The utterly empty bottle of his soul.”

“I mean, you could claim that anything's real if the only basis for believing in it is that nobody's proved it doesn't exist!”

“You can exist without your soul, you know, as long as your brain and heart are still working. But you’ll have no sense of self anymore, no memory, no . . . anything. There’s no chance at all of recovery. You’ll just — exist. As an empty shell. And your soul is gone forever . . . lost.”

“I am an empty mind with an empty body and with an empty soul. I am neither haunting for anything nor something.”

“If there are no self-evident first principles, as a foundation for reasoning to conclusions that are not immediately apparent, how can you construct any kind of a philosophy? If you have to prove even the basic axioms of your metaphysics, you will never have a metaphysics, because you will never have any strict proof of anything, for your first proof will involve you in an infinite regress, proving that you are proving what you are proving and so on, into the exterior darkness where there is wailing and gnashing of teeth. If Descartes thought it was necessary to prove his own existence by the fact that he was thinking, and that his though therefore existed in some subject, how did he prove that he was thinking in the first place? But as to the second step, that God must exist because Descartes had a clear idea of him – that never convinced me, then or at any other time, or now either. There are much better proofs for the existence of God than that one.”
