The lure of large salaries is likely to appeal more to conservatives than to liberals.
Now there’s someone who’s not entertaining stereotypes!
Patrick’s argument focuses more on the "progressive" character of the research ideal that has come to define the American university. Where once colleges and universities were "conservators" of a cultural tradition (which might have contained a plurality of views, not to mention the resources for self-criticism), they’re now essentially "progressive," in the sense that the accumulation of a body of knowledge is progressive (at least since the Enlightenment). Everyone’s a scientist of a sort:
The infiltration of the canons of scientific research into the humanities has been the root cause for the decimation of the very idea of the humanities on our campuses. In their efforts to prove their "originality" and progressiveness faculty glommed onto post-structuralism, post-modernism, post-colonialism, and post- everything in order to prove that they were "with it," and indeed, that they were anything but "conservative" - that is, the one thing that made the humanities defensible inasmuch its reason for existence is to be conservators. By demonstrating their hostility to the authors and books they studied or even the very idea of "humanity" (what is now fashionably called "the subject"), the humanities at once made themselves "relevant" and destroyed themselves from within.
