Ideas, cultures, and histories cannot seriously be understood or studied without their force, or more precisely their configurations of power, also being studied.

The prevailing situation of criticism ... has given rise to a cult of professional expertise whose effect in general is pernicious. For the intellectual class, expertise has usually been a service rendered, and sold, to the central authority of society. This is the trahison des clercs of which Julien Benda spoke in the 1920s. Expertise in foreign affairs, for example, has usually meant the legitimization of the conduct of foreign policy and, what is more to the point, a sustained investment in revalidating the role of experts in foreign affairs. The same sort of thing is true of literary critics and professional humanists, except that their expertise is based upon noninterference in what Vico grandly calls the world of nations but which prosaically might just as well be called “the world.” We tell our students and our general constituency that we defend the classics, the virtues of a liberal education, and the precious pleasures of literature even as we also show ourselves to be silent (perhaps incompetent) about the historical and social world in which all these things take place. ... <p>Humanists and intellectuals accept the idea that ... cultural types are not supposed to interfere in matters for which the social system has not certified them.

As a way of maintaining relative intellectual independence, having the attitude of an amateur instead of a professional is a better course.
