Utterly banal. For one thing, to say that life supervenes upon chemistry which supervenes upon physics is actually taking the _opposite_ position than "life is emergent," at least to the extent that philosophers agree about what emergent means. I understand emergence to mean what Deacon means: the properties of the emergent system are independent from the properties of the system underneath it at least to the extent that you couldn't predict the behavior of the emergent system with just the physics, at least not without a lot of work and the specific initial conditions required. The idea being that many possible systems could serve as the basis for the emergent system and that the emergent system is some kind of set of self-reinforcing constraints imposed on the underlying system. As it happens, I don't believe this argument if taken all the way. Sure, emergence has the property that, in some sense, one knows more about the emergent system if it is described at its own level rather than at the level of the underlying system (eg, if you tell me you are hungry I'm much more likely to correctly predict you will order pizza than if you give me a catalog of the state of all your neurons), but your behavior still supervenes upon the neurons inexorably. Even the constraints that maintain the emergent system ultimately are expressed in terms of the underlying system. |

Emergent is that produced/provided (as a potential) of a system which is greater than the sum of its parts.
Absolutely everything new you can do by arranging a few independent things for an outcome which could not have been achieved otherwise (literally creating potential in the universe) is "emergent."
So driving great distance and speed in metal chariots emerges from our technology for cars.
Flight emerges by airflow physics and the trimtab.
Life emerges by eating and crapping dense energy, propagating the continuity of existential being.
