In recent years we have witnessed major developments in philosophical inquiry concerning the nature of law and, with the continuing development of international and transnational legal institutions, in the phenomenon of law itself. This volume gathers leading writers in the field to take stock of current debates on the nature of law and the aims and methods of legal philosophy. The volume covers four broad themes. The essays within the first theme address and develop the traditional debates between legal positivism, natural law theory, and Dworkinian interpretivism. Papers within the second theme focus on the power of coercion, often overlooked in contemporary legal philosophy. The third set of papers addresses the aims and methods of legal theory, and the role of conceptual analysis. The final section explores new methods and issues in the subject, and offers fresh starting points for future work in the field. Gathering many leading and up-and-coming writers in the subject, the volume offers a snapshot of the best current work in general jurisprudence.
