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.
