@north,
Permit me some unverifiable speculations. Is it not possible that if it is the case that consciousness has no definite location, that it is in the nature of all things? Nature HAS consciousness (mine and yours reveals that right now) therefore it IS, in that sense, conscious.
The opposite thesis is much less acceptable (intuitive) to me, namely that Nature is dead/innert as far as consciousness is concerned. Perhaps it is acceptable to describe Nature as Unconscious since, when it applies to animal life "unconsciousnes" is a form, or level, of consciousness. Perhaps we should be keenly alert to a possible range of types and degrees of awareness.
Possibly we should realize that Algae does not have consciousness in anything like the sense that we have it, but given its membership in Nature it IS consciousness.
Again, algae is a form of LIFE as well. But then let's, for the purpose of our discussion, broaden our conception of life to include ALL things including rocks. Perhaps the very fact of the great dynamism/movement of a rock's atomic and sub-atomic levels-of-being is grounds for considering it--like all things--alive.
In that case biology addresses a particular subset of Life.
