"mind" as a noun If we were all to come to the agreement that the mind is what the brain does (not that I know that we will), would it still make sense to still use "mind" as a noun? To try an analogy, "running" I suppose, makes sense as a noun and running is what the legs do. But "mind" and "running" are different kinds of nouns. (someone help me with the linguistics here). The kind of noun that "mind" is, seems to imply some sort of substrate, something separate and locatable in space. (We can "lose our minds" or ask "what's on it".) Or we can see it as a collection of activities that can be bound up as a complete concept, which is maybe not that helpful if we can just as easily describe them by the different processes. We don't have a collective concept for "run, walk, step, sprint, etc." for all the various things legs can do. We don't say "leggage" or "the leggage" as a catchall term for all the things that legs carry out. What are some reasons for keeping "mind" as a noun in this scenario?
