ABSTRACT
The claim that orients Badiou’s entire reading of Deleuze is infamous: “This philosophy is organized around a metaphysics of the One” (DCB 17/30). As philosopher of the One, Badiou claims that Deleuze has for the most part been remarkably successful. We are dealing therefore not with a failed or impossible philosophical project, but one that Deleuze has more or less successfully executed on behalf of contemporary thought. The closing lines of The Clamor of Being invoke Deleuze as “truly a most eminent apostle” (DCB 102/150) of the Spinoza for whom Being is radically unary in nature. If, as I shall come to argue, Badiou’s argument on this point fails, then the veracity of the rest of his reading of Deleuze is profoundly challenged.
