Full Idea
There is a distinction between the Subject, and one or more Selves. The Subject is the locus of consciousness, experience, reason, will, and our 'essence' (or true Self). The Selves consist of our bodies, social roles, histories and so on.
Gist of Idea
The Subject is the focus of living, and the Selves are related images

A Reaction
[Based on Lakoff/Becker 1992 research] The distinction is never made clear, but seems plausible. It would make the Subject a real entity (as the brain's central control) and the Selves a set of fictions.
