This is what Rosen called for in "Drawing the boundary between subject
and object:Comments on the mind-brain problem". Theoretical medicine 14:
89-100 (1993). We need to move the boundary to include these
discussions.

Organisms are not "reactionary" systems as implied here. They are
anticipatory. [R. Rosen: Anticipatory Systems, 1985]

It is interesting to me how much of this was done well by Rosen as far back
as the 1960's. See the "Rosen Bibliography" @ http://views.vcu.edu/complex
