In this article I offer a critical examination of Giorgio Agamben’s vision of political liberation as it is articulated in his philosophy of language. Focusing on his affirmative politics as a particular kind of performance, I show that he has in mind a radically ‘pure’ performative that affirms only language as such. This conception is very different from other influential approaches to performativity in the contemporary scene of political thought, such as those developed by Jacques Derrida and Judith Butler. Rather (...) than offering a meaningful alternative to these approaches, however, I argue that this pure performative makes visible the specific problems connected to Agamben’s model. Ultimately, Agamben risks affirming what he sees as problematic in political terms, namely the isolation of his preferred type of experience of language to a separate ‘sphere’. It is, moreover, questionable whether his performative points to a plausible model of political contestation in an age where careless and void utterances have become widespread. (shrink)
