It might be easier to understand what I was trying to get at yesterday, with my rubrics about poetry's transcendental perfection, if we think of such a characteristic as analogous to what music is & does.
I don't want to think of music "inhabiting" poetry, translating it into an unknown beautiful dream-speech (symbolism). I want to think of the harmony of poetry as sui generis, as applying its own peculiar powers & methods; but that the beauty expressed in painting & music is evidence of analogous forms of harmony.
I think of poetry's harmony as global, manifest in all languages. Global, yet strict. Something different from Ron Silliman's or Josh Corey's "post-avant community".
The strictness I'm talking about has to do with beauty's inherent qualities, which, in poetry, encompass the objects of both sense & intellect, and have to comprehend all the human & natural constructions which make up tradition - going back to the origins of language on the one hand, and the origins of the universe on the other.
