Rosenberg's Argument Against Beliefs

[Neo-Scholastic]

...Just because mind/consciousness has only been reported by creatures with brains is no reason to jump to the conclusion that mind processes are nothing but brain chemistry.

That is exactly correct. If not just electro-chemical processes then what is the extra ingredient?

Clearly all that brain chemistry is giving rise to all the subjective states we know and love.

I do not share your clarity. To say "gives rise to" restricts you to bottom-up causation. The naturalist assumption is that the physical universe is causally closed. Thus naturalist explanations only allow bottom-up causation. If there is an extra ingredient for consciousness, then it has no place in any purely physical system.
