"This collection of essays, perhaps more than any other of his groundbreaking books, shows Brian Massumi to be a profoundly political thinker. Its analyses of capitalism are startling, radical, and convincing. And its presentation of domination and violence as the curtailment of a more primary force that is life-enhancing and life-changing will alter the way you think about the political future. Readers will also find elegant accounts of many of Massumi's key concepts, including perception, the virtual, affect, aesthetics (as that which pertains to qualities of experience), sympathy, the outside, dividuality, and the supernormal. A fabulous resource for thinking otherwise."–Jane Bennett, author of "Influx and Efflux: Writing Up with Walt Whitman"
