I have reached page 416 of Penrose's Emperor's New Mind and nowhere, nowhere, does he take the position or imply that "consciousness is material". It cannot be algorithmic and all indications so far point toward immateriality. Penrose writes, among many other things, of aesthetics and beauty as indicators of mathematical truth.
Reread post 3986. As I said, that came from Shadows of the Mind, page 12 (and subsequent).
