This article analyses Achille Mbembe’s theorization of necropolitics and surplus life in dialogue with three comparable theorizations: Agamben’s ‘bare life’, Marxist scholarship on ‘relative surplus populations’, and Afropessimist theorizations of ‘social death’. I argue that Mbembe’s work allows us to develop a critique of sacrifice that at the same time (contra Agamben) recognizes how it plays a structural role within necropolitics. Examining the influence of Georges Bataille’s writings on sacrifice allows me to clarify this argument. The second part of the (...) article examines the ‘surplus life’ of necropolitics in comparative analysis, tracing some of the limits of Mbembe’s reading through a dialogue with Marxist and Afropessimist readings. I characterize Mbembe’s work in terms of a poetics and politics of surplus: ‘reserves of life’ are affirmed against the excess of violence characterizing the present. However, this critique of violence relies upon abrupt leaps from politics to abstract ethical appeals in ways that obscure the implications of Mbembe’s own analysis. (shrink)
