This interdisciplinary collection of essays demonstrates how the ethical and political problems we are confronted with today have come to focus largely on life. The contributors to this volume define and assess the specific meaning of life itself. It is only by doing so that we can understand why life has become an all-encompassing problem, why all questions, especially ethical and political, have become vital questions. We have reached a moment in history where every distinction and opposition is no longer in relation to life, but within it, and where life is at once a theoretical and practical problem. This book throws light on this nexus of problems at the heart of contemporary debates in bioethics and biopolitics. It helps us understand why and how life is understood, valued, cared for and framed today. Taking a genuinely transdisciplinary approach, these essays demonstrate how life is a multifaceted problem and how diverse the origins, foundations and also consequences of bioethics and biopolitics therefore are.
