Focusing so much on poetry & painting these days, I should re-read Elizabeth Willis' Turneresque. I see Catherine Daly is working on a review.

         ...there
Everyone knows, serious life
Is elsewhere.

Of course, was reading BJ Leggett's fine book again today, Wallace Stevens and Poetic Theory : the chapter dealing with what Stevens drew from Charles Mauron's book Aesthetics and Psychology, in particular the bit about the usefulness of obscurity:

the poem must resist the intelligence
almost successfully...

- which section pretty much contradicts everything I've been saying here. For Stevens, at least during a phase of his career, poetry opposes paraphrase and explanation... but I can't adequately paraphrase this excellent study right now...

"Resonance" and "Symbolism", Jonathan & Kent - they both seem relevant to the process I'm trying to outline. Resonance closer to Stevens, in that it has no implication of fixity of "image"; Symbolism - Yeats was clearly a symbolist of a sort - but the word seems too systematic, like allegory - for what I'm thinking of. Actually Greg's definition of "vision" seems about right.

The poem integrates its parts in such a way that they begin to resonate overtones of "symbolic" meaning, they are iconic pointers, aspects of a whole representation, with which the reader can identify or feel-with-affinity in several ways at once.
Such that a context is provided for individual images proper, or strings of imagery, which begin to echo in the reader's sensibility.

"Aura", writes Catherine... now that's hovering somewhere between resonance and vision!
