Geoff Pfeifer’s The New Materialism provides the definitive account of the contemporary emergence of a form of materialism that goes beyond both traditional materialism and idealism. He sees how Althusser’s incisive reading of Marx unleashed a complete rethinking of materialist philosophy. No one will be able to think about materialism in the same way after reading Pfeiffer’s groundbreaking book.Todd McGowan, Associate Professor of English, University of VermontWith the ‘return of Althusser’ in the contemporary philosophical and political debates, Geoff Pfeifer’s The New Materialism: Althusser, Badiou, and Žižek offers the most detailed investigation and reconstruction of Althusser’s materialism, and it’s influence on the two great contemporary philosophers, Badiou and Žižek. A must read for anyone who is interested in the contemporary revival of materialism.Agon Hamza, author of Althusser and Pasolini: Philosophy, Marxism, FilmGeoff Pfeifer’s The New Materialism is essential reading for anyone interested in debates on contemporary materialist philosophy. Not only does Pfeifer provide clear and insightful readings of Badiou and Žižek; the book also applies their work to a rejuvenation of the materialism of Althusser. Reading Althusser through the prism of Badiou and Žižek, as well as the original political context of Althusser’s political philosophy, Pfeifer demonstrates with precision important ties between these three key thinkers. Without idealizing the work of Althusser, the book shows just how in their reactions to him, Badiou and Žižek see through, each in their own way, corrections to his project to rid Marxism of its idealist and teleological variants, while still brining it to its full realization by developing approaches atypical of the idealism/materialism divide. Pfeifer ultimately explains why anyone wishing to grasp the "new" significance of Althusser’s materialism must first pass through Badiou and Žižek.Matthew Flisfeder, Assistant Professor, Dept. of Rhetoric, Writing, and Communications, University of WinnipegGeoff Pfeifer makes one thing clear: it is all but easy to be a materialist in philosophy today. Until the mid 20th century, materialism consisted mainly in recognizing necessities and in resisting illusions of freedom. Today, however, we have to recognize, following Louis Althusser, that there are illusions of necessity that a "new" materialism has to break with. Only in this way can the underlying aleatory encounters be revealed, encounters that allow for unexpected social change. Pfeifer's scholarly meticulous, but easy to read elementary study, introduces the reader to the most prominent elaborations of this program by Alain Badiou and Slavoj Žižek. This book is a milestone on the way for anyone trying to be a materialist in philosophy these days, and a benchmark for all the fashionable attempts that claim to have already reached this goal.Robert Pfaller, Professor of Cultural Theory at University of Art and Industrial Design, Linz, Austria.
