that's a very provocative set of quotations you've marshalled, angela, but can't the point of it all be put more simply? i.e., the academy always shills for state power (and the "natural" pre-eminence of the ruling orders)?
and that's true whether it's a matter of prescriptive sociology or the more contemporary pomo "radicalism," which serves mainly to create/reinforce a sense of powerlessness.
