> Even if you are a full materialist it's fallacious to assume there is one "part" that does something, like it's a factory assembly. Instead it might be a function of the composition of brain parts.
Its true that a particular function may mot be localizable more specifically than the brain (or even the whole body), because defining it as a distinct function may not reflect the organization of conponents within the body. But that's still performed by a defined physical system, and there are still sub-functions necessary to perform that function that are localizable to narrower components.

Its like that in that we absolutely can describe specific parts of the bat and what each contributes to flight.
