Convergent evolution

Let's apply it to mathematics. Let's suppose that many different rational animals on different planets are capable of knowing the same mathematical truths, just as many different animals on our planet have independently evolved eyes for seeing light. It would seem that just as the many seeing animals share in common a light-filled environment, so too the many calculating animals share the same (think Plato) mathematical environment in common. Especially if what they know is the same.

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...

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...

If the universe is eternal and determinism is true, then...

...in that case it would be possible in principle to retrodict the past ad infinitum. The present would either contain an infinite amount of information or the universe would be cyclical, albeit (methinks) in a manner analogous to the plot of the Lorenz attractor.
