Abstract: This book argues that we live in an age of somatic subjects, whose authentic identity must be represented through the body. When a perceived mismatch between inner self and outer form occurs, technologies can step in to change the flesh. Drawing on Wittgenstein's objections to the idea of a private language, and on Foucault's critical account of normalization, this book shows how we have been led to think of ourselves in this way, and suggests that breaking the hold of this picture of the self will be central to our freedom. How should we work on ourselves when so often the kind of self we are urged to be is itself a product of normalization? This question is answered through three case studies that analyze feminist interpretations of transgender politics, the allure of weight-loss dieting, and representations of cosmetic surgery patients. Mixing philosophical argument with personal narrative and analysis of popular culture, the book moves from engagement with Leslie Feinberg on trans liberation, to an auto-ethnography of Weight Watchers meetings, to a reading of Extreme Makeover, to the author's own practice of yoga. The book draws on philosophy, sociology, medicine, cultural studies, and psychology to suggest that these examples, in different ways, are connected to the picture of the somatic subject. Working on the self can both generate new skills and make us more docile; enhance our pleasures and narrow our possibilities; encourage us to take care of ourselves while increasing our dependence on experts. Self transformation through the body can limit us and liberate us at the same time. To move beyond this paradox, the book concludes by arguing that Foucault's last work on ethics provides untapped resources for understanding how we might use our embodied agency to change ourselves for the better.
