Kasey writes, interestingly :

What connotations, resonances, moods do the patterns evoke? We are veering, or threatening to veer, back to the realm of the referential and the conative (and maybe the emotive itself), but the added element here is something like a belief in, or a wish for, a kind of magic: for the transformation of mere phonemes and syllables into transcendental conveying devices, Cloudy Symbols of a High Romance. It is this romantic valuation that is anathema to the theory behind much Language Poetry, and that is still a beguiling beacon for James, with his New Brutalist’s heart pumping pure Keatsian nectar instead of blood.

So maybe when it is objected that Language Poetry is unemotional, what is really meant is that it forecloses the possibility of using emotions as a portal to a privileged perspective outside materiality. A poetics that wants to take issue with such a foreclosure, moreover, has its work cut out it for it (if it proposes to take issue in a public forum among which there are Language Poets and other materialists, at any rate). Or, coming at the same problem from another angle, how does the New Brutalism propose to answer the inevitable charges of escapism, mystification, naive romanticism, etc.? Or will it ignore these charges and their attending sociopolitical imperatives entirely, content to pursue a pastoral ideal of sweet mad hedonist piping in the polluted garden of contemporary life? The world watches and waits.

One question for Kasey : why must the emotive function, ravelled into the poetic as he describes, be necessarily otherworldly-Romantic? It seems to me that the poetic expression of emotion is often very this-worldly, situational : one of poetry's fantastic capabilities is to evoke a tense dramatic human situation through understatement, thus playing upon deeply mixed emotions (both the emotions deriving from the immediacy of a critical situation, as well as those deriving from an ironic or retrospective distance from those events).

It seems to me that foregrounding this opposition between idealist & materialist ideology is exactly the "argument" of Language poetry - an argument which elides these other potential capabilities & engagements.
