Maybe a better name might be the “integrated brain”. This seems to be the idea of Jaynes, for one. I was quite impressed by his book, although I couldn’t agree with his conclusions. Even so, the scope of his thinking impressed me. After all, if you believe that there was a natural origin of human consciousness, you must face the question how it occurred.

I will say that whatever the natural history of consciousness may be, its mere existence is beyond the ken of materialist philosophy.

Some people think that the brain created consciousness.
I think it is the other way around.

Jayne assumed mankind had EVOLVED into a state in which human societies were controlled by what he termed a system of shared auditory hallucinations; that is clearly unworkable. The rest of his findings appear believable enough, particularly the use of a part of the human brain which is no longer used. More likely is that he was investigating a period of time (between Moses and Alexander more or less) during which the phenomena he described was DEVOLVING into dysfunction and ultimately disuse, and that the original use of these phenomena prior to the flood and the tower of Babel had been human communication.

There is no real way to believe that present human languages evolved from some original spoken language like ours, too many things such a theory could never explain.
