Fredric Jameson, "Postmodernism and Consumer Society" (1983):
    "A generation ago there was still a technical discourse of professional philosophy–the great systems of Sartre or the phenomenologists, the work of Wittgenstein or analytical or common language philosophy–alongside which one could still distinguish that quite different discourse of the other academic disciplines–of political science, for example, or sociology or literary criticism.  Today, increasingly, we have a kind of writing simply called 'theory' which is all or none of those things at once.  This new kind of discourse, generally associated with France and so-called French theory, is becoming widespread and marks the end of philosophy as such.  Is the work of Michel Foucault, for example, to be called philosophy, history, social theory or political science?  It's undecidable, as they say nowadays; and I will suggest that such 'theoretical discourse' is also to be numbered among the manifestations of postmodernism."
