OK, so the mind is what the brain does. But how meaningful is it to describe what the mind does in neurological or biochemical terms? Isn't the process by which a thing works in a different domain to the thing itself?
The brain is a physical thing, an evolved bio-mechanism, part of a process, billions of years old, by which entropy generates complexity.[*] The brain is part of the universe of atoms and genes. The mind is an ephemeral thing, a lossy information storage, retrieval and recombination engine running on an operating system called "language" (and probably other levels, Wang's Carpets-like, beneath), part of a process, thousands of years old, by which society generates culture. The mind is part of the universe of patterns and memes. Just as software is not hardware and the map is not the territory, the mind is not the brain.
I'm a dualist. Why aren't you?
[* It's really the tendency of physical interactions to increase entropy—ie. to move towards equilibrium—which generates complexity, but that doesn't sound as good.]
