It certainly has more to avail itself than the Aristotelian idea that the "brain" (then it was thought your "heart") was a hollow "acceptor" of your consciousness. Or, in other terms, a hollow "machine" for your "ghost." -We have no valid explanation for how consciousness could be "outside" of you, therefore it stands to reason that the brain IS you.
