This is the classic study of the history and continuing philosophical values of the law of nature. D'Entreves discerned three distinct sources that have contributed to the development of natural law: Roman law teachings, Christian beliefs regarding law, and egalitarian and revolutionary theories of the Enlightenment. Now regarded as a classic work, Natural Law has exercised considerable influence over the course of Anglo-American legal theory in the past forty years. The statements of Clarence Thomas during his 1991 Senate confirmation hearings show that the law of nature still holds powerful appeal in defining judicial rules. In the new introduction, Cary J. Nederman points out both the contemporary value and the historical significance of Natural Law. He also provides the biographical as well as intellectual context for d'Entreves immense accomplishments. This volume is essential reading for students of legal history, political theory, and philosophy. It will also be of interest to historians.
