Rob,
That's an interesting one to respond to: 'Being' versus 'Seeming'.
You say "I'm a materialist, but I do not "seem" to be such a being." In your previous comment you remarked you could imagine how to construct automata, but not aware automata [I'm paraphrasing.]
I think your definition of "material" is too constrained. Along with many others, I view the gravitational field as "material". As Ohanian and Ruffini say in "Gravitation and Spacetime, 2nd Ed.": "the gravitational field may be regarded as the material medium sought by Newton; the field is material because it possesses an energy density." And as Weinberg notes in "Gravitation and Cosmology" -- "the geometric interpretation of the theory of gravity has dwindled to a mere analogy."
But you do not understand how gravity "pulls" on other mass. And you do not understand how gravity is "aware of" other mass. I contend that these mysterious aspects, plus the concept of energy/mass, pretty well define gravity. And gravity self-gravitates. And I am aware of gravity and of myself. And my theory explains how gravity evolved from an initial 'pure' symmetry to our current world, which is a complex manifestation of the original material substance.
It seems to me you have several choices:
1) enlarge your concept of material to include awareness and volition (like gravitational attraction).
2) hypothesize another "field" to explain awareness.
3) believe the conventional view that awareness emerges from complex automata (and hence has no fundamental reality, only artificial).
4) believe in some "other" realm, such as Platonists do [Penrose is a Platonist].
My bias is to prefer ONE thing to two or many things. And the one gravity field seems to work. I don't think the other ideas work, or if they do, I find them "ugly". It's a personal preference, but, as I've indicated above, my theory explains (qualitatively) anomalies in (material) physics that no one else explains.
I've often used the example in your last paragraph (seeing 'red') to explain to others what I mean by awareness.
I think you are mistaken in your belief that some undiscovered info processing will "explain" awareness, just as no undiscovered geometry will "explain" how gravity 'pulls'. It 'describes' at best.
Although I believe everyone began in the womb with what I refer to as topological awareness, it is clear that most have no recollection of such and have effectively lost this mode of awareness. Psychedelics, strokes, and religious experiences restore this mode, temporarily. If none of these apply to you, then you will probably deny this fundamental mode of awareness even exists. I view such experience as a surefire way to put ideas of algorithms or mechanical explanations of awareness to bed. And I consider my theory a 'materialist' theory of physics, based on the two things I directly and immediately experience: gravity and awareness. Almost everything else is abstraction and idea, which requires working logic circuits to experience.
While I've been beating this drum for years, it's good that FQXi has finally come up with a topic that causes numerous people to see that consciousness must be discussed in any fundamental theory of information.
Thanks again for your always stimulating comments.
