Paulhanke,
Excellent point Paulhanke, but, as an evolutionary consideration it is foolish to consider the mind proceeding the body in development. If you consider this development then you must come to the conclusion that the body produced the mind. You however are correct, in considering function, one cannot separate these things. It does however, for some reason seem self-evident to me, that the mind/brain is in service to the body, certainly it is not the other way around. When the mind wants what the body does not, one has a problem.
