The Hypothesis of Extended Active Maintenance Cognition

In Radical Embodied Cognitive Science, Chemero writes "I take it that cognition is the ongoing, active maintenance of a robust animal-environment system, achieved by closely co-ordinated perception and action." (fn #8, p. 212).

This, of course, allows us to frame what we might call the hypothesis of extended active maintenance cognition
(HEAMC):  Active maintenance cognition (sometimes?) extends beyond the boundaries of the brain into the body and physical world.

Now, we have something to talk about.  We can begin to explore, for example, what relation there might be between (HEFC), (HESC), and (HEAMC).
