Dear Laurence,
Thanks for your comment and questions. As I noted on your page, you handle "bit as fundamental" and "universe as computer" so masterfully that the topic should be closed! Nevertheless, if you'd like to see how fascinating the "other side" can be, I recommend Hugh Matlock's essay [see comment above yours.]
You point out a little-noted fact, that "nearly all of mathematics has no relevance to the physical world" and conclude "therefore some additional fact of reality must account for actual existence." Then you ask if I agree that math is useful for understanding physical existence, and whether it does not have a Platonic reality of its own, noting that I begin with an equation...
My basic assumption is that the universe either began as ONE thing, from which ALL evolved, or it may as well of been created with billions of things. Once we assume more than one thing, why stop at two? And the Platonic reality of math is more than ONE thing. But further, I find that the existence of physical thresholds (which falls out of the Master equation with the quantum of action) leads to natural binary states and physical continuity (assumed in the Master equation) that leads to 'circuitry' or connections between such states that easily implement logical circuits AND, OR, XOR (COMPARE) and that such gates easily implement ADD and SUBTRACT circuitry and, as noted in Hugh Matlock's comment above, floating-point computation. Kronecker famously said "God made the integers, all else is the work of man." Since the integers derive from simple counter circuits (which can be implemented in DNA, silicon, or neurons, etc.) I find that math is a "side effect" of physical reality. In other words, physical reality instantiates 'logic', probably as a necessary consequence of self-consistent existence, and physical logic leads straight-forwardly to counters, natural numbers, and all of math. There is no reason to assume another Platonic 'realm'. I suspect this is just part of the confusion that generally surrounds consciousness.
But math circuitry, like logical circuitry, leads to language, and just as natural language can produce fiction having only remote ties to reality, mathematical language can be untied from reality. As you note, this is why we cannot conclude that physical reality derives from math, because why just "some" math and not "all" math?
You also agree that "awareness is a genuine feature of reality." You ask whether I would consider my position a kind of panpsychism. I guess I'd have to say it is a "kind of" panpsychism, although, as I understand it, panpsychism generally ignores relations to physical reality. So I think I'm more 'nuanced' than panpsychism, and, not having any conjecture about the 'cause' of physical reality, I leave the door open to a "higher cause".
You further ask whether the universal aboriginal awareness and the self-interaction which gives rise to the physical world are two separate properties of the field or two aspects of the same property, or something else. First, I should note that the self-interaction does not "give rise to the physical world". I don't know what gave rise to the physical world, but I'm convinced that those who believe that mathematics (or information) can or did give rise to the physical world are badly mistaken. But since we find ourselves in (and are directly aware of) a physical world, I start with the simplest possible world, one field, and conclude that, to evolve, it could only interact with itself. There was simply nothing else to interact with!
And I find this reasonably implies that to interact with itself the field must have "some" awareness of itself. I would probably not insist on this aspect (?) except for the fact that I have awareness of myself, and based on experience and on reasonably expert awareness of computers and biology, I don't think my awareness is an artifact. Therefore I conclude its primordial. With this assumption I find that everything I know of could reasonably have evolved from the one aboriginal field. What brought that field into existence is an ultimate mystery and will certainly never be "logically" explained.
Your final question, whether awareness, consciousness, and thinking are something other than the way they present themselves to us, is the essence of Korzybski's dictum. They *are* the territory.
Thanks again Laurence, for your essay and for your comment. I noted on your page weeks ago that your essay was worth a 10 but I didn't score it at the time. I've just remedied that.
