Is it a form of consumption- only if heat is released I guess? It is presumably a sliding scale, though, in terms of some things more actively consuming order than others. If you want to define a proton as slightly alive, fine, though it's not very proactive in its consuming of things, it just waits around to bump into the right particle at the right speed. An amoeba is considerably more proactive about it, a fly even more so. I'm not trying to retreat to the old notion of "movement" as a criterion for life here, there is something else that defines this scale (given the known correspondence between information and entropy - computation?) I'm guessing Schrodinger had thought about the atomic mass thing, though. I'd check out his very short and readable "What is life?" if you haven't already.

I have glanced over Shrodinger's "What Is Life?" previously. Life is thermodynamics, information/entropy/computational like you said. Clearly the lines are blurred and the definition of life in biology textbooks is quite poor. Still, this all begs the question of whether the particles that dominate our universe are species or are inherent from the physical laws. Then when you consider that the laws themselves may be species ..well..shoot me already. My head has begun to hurt.

  Maths has techniques for dealing with infinite regress - limits as N tends to infinity, fixed points, etc. Intuitively these all seem to rely on a fixed external structure of some sort (e.g. the eigenvectors of M depend on fixed M) but I wonder if there's some formulation of these techniques that doesn't?

    Maths has the same issue with the primes. Their definition is a recurrence with respect to themselves. If the universe is a "strange loop," like Hofstadter says, then we have very little hope of understanding a snake eating its own tail from our hierarchical models.
