Book excerpt: This book is a study of the relations between the body and its technologies in modernism. Tim Armstrong traces the links between modernist literary texts and medical, psychological and social theory across a range of writers, including Yeats, Henry James, Eliot, Stein, and Pound. Armstrong shows how modernist texts enact experimental procedures which have their origins in nineteenth-century psychophysics, biology, and bodily reform techniques, but within a context in which the body is reconceived and subjected to new modes of production, representation and commodification. Drawing on a wide range of disciplines, Armstrong challenges the received oppositions between technology and literature, the instrumental and the aesthetic, by demonstrating the leaky boundaries and complex interconnections between these domains. This book offers a cultural history of modernism as it negotiated the enduring fact of the human body in a period of rapid technological change.
