Bringing together authors from two intellectual traditions that have, so far, generally developed independently of one another - critical theory and new materialism - this book addresses the fundamental differences and potential connections that exist between these two schools of thought. With a focus on some of the most pressing questions of contemporary philosophy and social theory - in particular, those concerning the status of long-standing and contested separations between matter and life, the biological and the symbolic, passivity and agency, affectivity and rationality - it shows that recent developments in both traditions point to important convergences between them and thus prepare the ground for a more direct confrontation and cross-fertilization. The first volume to promote a dialogue between critical theory and new materialism, this collection explores the implications for contemporary debates on ecology, gender, biopolitics, post-humanism, economics and aesthetics. As such, it will appeal to philosophers, social and political theorists, and sociologists with interests in contemporary critical theory and materialism.
