Enjoying this discussion, thank you, even though much of it is over my head. I guess my comment is a cautionary one. In trying to articulate the character of poetry's picture-logic - how it manages to present something real or coherent or telling - there's a danger of imposing some kind of determinism. For me what primarily differentiates poetry from science & philosophy is its contingent quality - something you touched on in comments about the writer/reader relationship, but I think it needs to be underlined. Poetry (or creativity in general) occupies a contingent Now which escapes ordinary notions of causality. Ironically, this activity may present the most accurate "picture" of reality.I think Henry's concern about determining the beheld is proper. I am more inclined to discuss the object of poetry as revealed much in the way Edward Taylor and Anne Bradstreet address it. What I behold in the world, in nature, is approach by me in many ways. Regardless, the phenomenon must give itself up to show itself. Like the loon in my discussion of below, the poetic object calls out to announce itself. We may not hear it, we may not hear it at the right time, we may mistake it for something else, etc., but we certainly do not determine it. We can attempt to over-see it, but that will come out in the wash.
I haven't read Glazov-Corrigan's Mandlestam's Poetics. I understand the urge to write a humanist poetics, one that addresses a poetics for the human encounter. I just don't think such worries are important for the poet--they are fine ones to have--but I think they are much more vital to the critic who uses them. We find ourselves in poetry. We aren't necessarily working anything out. Maybe we are simply there, enjoying the difference between subject (of the world) and object (of the word) through revelation. I don't know.
