Responding to John Latta's notes on "ambiguous figures":

yes, the characteristic quality of poetry is its reflexivity (its way of being something rather than simply pointing to something); but the shortcoming of so much postmodern poetry is that it simply turns this into a dichotomy ("poetry must not be mimetic since it is reflexive, self-mirroring"). What happens then is it gets further and further from ordinary experience & feeling, accenting its function as intellectual game.

The real puzzle, it seems to me, is how poetry can be both mimetic & reflexive.
