It is a mantra, doomed to be repeated. It is not a plea. It is not an injunction. We cannot “forget” Foucault in the same way as, in another era, Marx could only repeat his distance from “Marxists” and the defeats of that other era turned Marxism into a dogma. In our era, the transformation of Foucault into the dogmas of “Foucaultians” and “post-Foucaultians” cannot be ended by the work of academics; it is not an academic problem. In the same way, the bloating of the discipline of IR, and the boom of dogmatic Foucaultianism within this, have nothing to do with academia per se, but how the world impinges upon and is reflected within disciplines, overdetermining the transformation of both what we call “IR” and what we call “political theory” and their inter-relationship. As Marxists, it is possible for us to understand how the transformation of Marxist thought into dogma was a necessary reflection of the degeneration of the liberatory political project of The Communist Manifesto , and, as Foucaultians, it is possible for us to understand how, in our era, the “disciplining” or “colonizing” of Foucault, within IR, is not a contradiction or a puzzle or an occasion for the allocation of blame but is a necessity. Why has IR “colonized” Foucault so easily, and yet found Marx so indigestible that he has been a constant mystery to the discipline itself? What is it about IR today that facilitates an appropriation of Foucault's epistemological framework in ways which have been much more problematic within political theory (which, of course, had no difficulty institutionalizing Marx in the academy)?
