This collection of essays from legal philosophers offers an assessment of the nature and viability of legal positivism, an approach to legal theory that continues to dominate contemporary legal theoretical debates. To what extent is the law adequately described as autonomous? Should legal theorists maintain a conceptual separation of law and morality? These and other questions are addressed by the authors of this collection, which should be of interest to all lawyers and scholars interested in legal philosophy.;This book is intended for scholars and postgraduates in philosophy, law, and legal theory.
