ABSTRACT
This chapter explores the restatement of Polanyi's treatment of the nature of the mind and its relation to the body in terms of their tacit integration such that philosophers attend from someone's bodily expressions and actions and to his mind. It contains some additional items, such as a clearer account of the functions of bodily processes of which the subject is not in any way aware and of why a neurologist studying them cannot dwell in them as he does in other aspects of the person whom he is studying. The joint viewing of two stereoscopic photographs offers a simple example both of contingent and logical irreversibility. Think of the differences in the two pictures, by virtue of which their joint viewing offers the sight of spatial depth. The structure and functioning of an organism is determined, like that of a machine, by constructional and operational principles which control boundary conditions left open by physics and chemistry.
