The biological revolution, with its attendant technological powers to alter nature and human nature, demands fundamental and cautionary reflection on questions of the highest ethical importance. In this thoughtful book on contemporary issues in bioethics, Stephen G. Post explores nine major topics ranging from birth and adolescence to aging and death. Using an interdisciplinary approach, Post clearly illuminates the issues, probes the ethical alternatives, and examines the cultural changes that shape current presuppositions about the right and good. This book will be of interest to scholars in bioethics, philosophy, and religious studies; health-care professionals; and the general reader concerned with these pressing questions of life and death.
