You can photosynthesize? I certainly can not (not being a tree). If I had
photosynthetic pigments in my skin, I suppose I could; and if I had rubbery
wings and sharp teeth I'd be a bat (if my aunt had wheels, she'd be a
wagon). I still can not see (intellectually) the "problem" of consciousness.
Consciousness /qualia, 1st person phenomena, etc, IMHO, being very poorly
defined, and likely non-existing entities, are a precarious pillar to base
any cosmology or metaphysics on. "Observer" is far superior, and lacks the
taint of dualism.
To borrow a page from Penrose, I see qualia in much the same light as a
shadow. Everyone can agree what a shadow is, point to one, and talk about
them. But a shadow is not a thing. The ancients made much ado about shadows,
ascribing all sorts of metaphysical significance and whatnot to them. I
think it is quite likely that the fuss about consciousness and qualia
resurrects this old mistake. Shadows of the mind, indeed.
