Natural law theory is enjoying a revival of interest in a variety of scholarly disciplines including law, philosophy, political science, and theology and religious studies. This volume presents twelve original essays by leading natural law theorists and their critics. The contributors discuss natural law theories of morality, law and legal reasoning, politics, and the rule of law. Readers get a clear sense of the wide diversity of viewpoints represented among contemporary theorists, and an opportunity to evaluate the arguments and counterarguments exchanged in the current debates between natural law theorists and their critics. Contributors include Hadley Arkes, Joseph M. Boyle, Jr., John Finnis, Robert P. George, Russell Hittinger, Neil MacCormick, Michael Moore, Jeffrey Stout, Joseph Raz, Jeremy Waldron, Lloyd Weinreb, and Ernest Weinrib. "This is a superb collection of recent essays in Natural Law Theory. The essays are sensibly organized, balanced in approach, and sufficiently diverse in approach to reveal the inherent complexity and controversiality of this once-passé and now vital topic."--Ronald Moore, University of Washington "This well-balanced collection provides a lucid and reliable compendium of the most important modern criticisms by and of natural law theorists in legal and moral philosophy. It is the best book of its kind."--James Gaffney, Loyola University "This is an excellent collection of recent work in natural law theory....This is a most useful collection for advanced undergraduates and graduate/law students."--Anthony J. Lisska, Denison University "[A] superb collection of original essays....For anyone who might still believe that natural law theory is merely a relic of bygone days...Professor George's book provides an indispensable antidote."-- First Things "George deserves congratulations for bringing together such an eminent group of scholars."-- Times Literary Supplement Robert P.
