The rise of computers and robots, heralded in science fiction and pervading ever more daily experience, has fostered a rampant temptation to model mind as a mechanism and expect machines one day to simulate all mental reality. This temptation reflects more than technological developments, however. It arises from the perennial dilemma of two complementary approaches to mind that proceed from the assumption of a mind/body duality: one conceiving mind to be wholly immaterial and the other reducing mind to inanimate matter. Exploring the difficulties of these views puts us in a position to evaluate the relation of mind and machine, helped along the way by key insights from Hegel.
The notion that mind cannot be material seems confirmed in every moment of self-consciousness, whose purely temporal flow of mental content testifies to the apparent nonspatial existence of mind. Yet so long as mind is construed as immaterial, it lacks the resources to have any temporal ordering, possess any unity, or retain any specifically mental character. Deprived of materiality, mental life is hardly distinguishable from a succession of logical categories that exhibit determinacy in general rather than anything particular to mind. The possibilities of any non-logical content are excluded. Lacking any embodiment, mind has nothing with which passively to receive content in the manner of sensibility, or to retrieve and refashion any such sensible content in images. Mind could perhaps generate conceptual content, but this would be indistinguishable from the thoughts that logic produces in its thinking of thinking.
