Full Idea
I am explicating the mental in a reductive way, by reducing mental characterizations to homuncular institutional ones, which are teleological characterizations at various levels of functional abstraction.
Clarification
'Homunculi' are small minds; teleological explanations refer to purposes
Gist of Idea
We reduce the mind through homuncular groups, described abstractly by purpose

A Reaction
I think this is the germ of a very good physicalist account of the mind. More is needed than a mere assertion about what the mind reduces to at the very lowest level; this offers a decent account of the descending stages of reduction.
