switching from the higher spheres to the higher symmetries

Okay: this may be a hot idea, or it may be plain nutty--but here goes:

Aristotle had the notion of the sublunar sphere and all within it being moved by the higher spheres. And the natural state of the motion of these spheres was motion rather than rest. We certainly don't have spheres any more, but from the point of view of physics (i.e., abstracting from biological questions) we do have a higher and lower. The higher has a kind of circularity about it. And a kind of simplicity about it (just as the movement of the spheres was thoguht to be circular. And the higher does drive the lower (at least until we get to questions of life). But the higher in this case is not above our heads. And it is not in any sense "macro" or large. Rather, it is micro. Yep, (at least if Stephen Barr is right) the smaller, less evident purely physical (i.e, apart from biological) processes have higher symmetry than the larger, more evident ones. Just as a marble (sez Barr) has more symmetry than a hexagon, yet the not-so-apparent circularity of the marble underlies and makes possible the more-apparent orderliness of the hexagon. And the less apparent physical level is naturally in motion.

response to friend who suggested that the self is a democracy of neural parts

This is a nice way to try to avoid being cornered re the irreality of the self if you're a reductionist, for you can assert that a pattern obtains at the microscopic level that is not all that unlike the pattern found at the societal level.  No need for the one self that does it all: instead, you have many sub-selfs that compete for dominance or take turns guiding the whole. The problem with this is, however, that the voters/officials are all zombies.  None of them thinks about the whole as such.  And perhaps none of them thinks even about themselves (unless one is a panzoist).  None of them makes a comparison of alternatives. The more this proposed democracy seems like a zombocracy, the more consciousness will be seem to be epiphenomenal. Furthermore, if the oneness of the self is less real than the multiplicity of explanatory neural parts, then why can't each of these neural parts be conceived of as democracy as well?  And why not parts of these parts, et...

what is an organism?

How about defining it as an instance of functional complexity? And treating the list of properties as following necessarily from this definition? Okay, this is very diamond-in-the-rough (or perhaps zirconium...) but here goes my thoughts on the matter: (Complexity) Many diverse parts (functional) acting for the sake of the whole I think I need to add something like "not as the instrument of another" or something like that. Given that they act together as one whole and given entropy, etc., the organism will need to posses more order than its surroundings (homeostasis). It will therefore need to take in energy (nutrition), which it will use to sustain its readiness to interact with its environment so as to preserve its own being (homeostasis again?), but which will eventually break down (death), so that in order for that life form to continue it will need to duplicate itself (reproduction), which, upon occurring, will involve both development (growth) to maturity and...
