Brian Leiter is widely recognized as the leading philosophical interpreter of the jurisprudence of American Legal Realism, and the most influential proponent of the relevance of the naturalistic turn in philosophy to the problems of legal philosophy. Naturalizing Jurisprudence collects newly revised versions of ten of his best-known essays. Leiter has supplied a lengthy new introductory essay, as well as postscripts to several of the essays, in which he responds to challenges to his interpretive and philosophical claims by academic lawyers and philosophers. This volume is essential reading for anyone interested in jurisprudence and the philosophy of law. "[A] work that goes well beyond the individual essays to present a trenchant, multi-faceted and mutually-reinforcing set of challenges to core views and methodologies that are prevalent in the field.... the book is also agenda-setting: it clarifies the impact that naturalistic developments in philosophy can have on core questions in analytic jurisprudence, while gesturing towards a larger and partly empirical project aimed at working out the full scope of these consequences for legal epistemology, the nature of law, and the objectivity of legal judgment.... an important book by one of the most influential legal philosophers of our time."--Robin Bradley Kar, Notre Dame Philosophical Reviews "This book will confirm Brian Leiter 's place in the front rank of legal theorists in the world today. Leiter is not just someone who writes well about what others have said. He has carved out a new path in legal theory, and set new standards for critical analysis and insight along the way."-- Jeremy Horder, Law Commissioner for England and Wales and Professor of Criminal Law, Oxford University "[ Naturalizing Jurisprudence is a work that goes well beyond the individual essays to present a trenchant, multi-faceted and mutually-reinforcing set of challenges to core views and methodologies that are prevalent in the field...This is thus an important book by one of the most influential legal philosophers of our time." -- Robin Bradley Kar, University of Illinois at Urbana-Champaign Provides a definitive philosophical interpretation of American Legal Realism, one of the most influential schools of modern legal thought.
