From The Existence Machine, an excerpt of an article by James Petras on the CIA and the Cultural Cold War, reviewing Frances Stonor Saunders' book, Who Paid the Piper: The CIA and the Cultural Cold War:
The CIA's cultural campaigns created the prototype for today's seemingly apolitical intellectuals, academics, and artists who are divorced from popular struggles and whose worth rises with their distance from the working classes and their proximity to prestigious foundations. The CIA role model of the successful professional is the ideological gatekeeper, excluding critical intellectuals who write about class struggle, class exploitation and U.S. imperialism, "ideological" not "objective" categories, or so they are told.
The singular lasting, damaging influence of the CIA's Congress of Cultural Freedom crowd was not their specific defenses of U.S. imperialist policies, but their success in imposing on subsequent generations of intellectuals the idea of excluding any sustained discussion of U.S. imperialism from the influential cultural and political media. The issue is not that today's intellectuals or artists may or may not take a progressive position on this or that issue. The problem is the pervasive belief among writers and artists that anti-imperialist social and political expressions should not appear in their music, paintings, and serious writing if they want their work to be considered of substantial artistic merit. The enduring political victory of the CIA was to convince intellectuals that serious and sustained political engagement on the left is incompatible with serious art and scholarship.
