Though contemporary European philosophy and critical theory have long had a robust engagement with Christianity, there has been no similar engagement with Buddhism&;a surprising lack, given Buddhism&;s global reach and obvious affinities with much of Continental philosophy. This volume fills that gap, focusing on &;nothing&;&;essential to Buddhism, of course, but also a key concept in critical theory from Hegel and Marx through deconstruction, queer theory, and contemporary speculative philosophy. Through an elaboration of emptiness in both critical and Buddhist traditions; an examination of the problem of praxis in Buddhism, Marxism, and psychoanalysis; and an explication of a &;Buddhaphobia&; that is rooted in modern anxieties about nothingness, Nothing opens up new spaces in which the radical cores of Buddhism and critical theory are renewed and revealed.
