Thanks so much, Mark - but if I'm back at all it's a very shaky back.
In my view the Sukenick book only seems lackluster because it is so workmanlike. He has no oversize thesis-axe to grind. He does paraphrases - which (understandably) many poets would consider the "murder-to-dissect" method.
I happen to need these paraphrases, because I am so dim, often miss the obvious. & by providing a rational structure to Stevens' meta-flora, Sukenick illuminates a terrain of composition which can be useful to other poets (me). I happen to need new themes, new somethings. My old approach seems to be finished.
