How should sociologists use the word theory? Gabriel Abend’s recent insistence that this question should be tackled politically raises two important issues: Is sociology political? And if so, what normative implications follow for its organization? Drawing on Wittgenstein’s notion of family resemblance and post-Gramscian theories of hegemony, I argue that Abend’s proposal that semantic questions about theory can be addressed separately from ontological, evaluative, and teleological ones is untenable. Disagreements about the latter are constitutive, not merely supplementary to the meaning (...) of theory. Against Abend’s deliberative-democratically oriented vision, I propose an agonistic politics of theory. In doing so, I consider both the internal inconsistencies of deliberativism and the practical advantages and sociological relevance of agonism. (shrink)
