This volume of essays by one of America's preeminent philosophers in the area of jurisprudence and moral philosophy gathers together fourteen papers that had been published in widely scattered and not readily accessible sources. All of the essays deal with the political ideals of liberty and justice or with hard cases for the application of the concept of a right. Originally published in 1980. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These paperback editions preserve the original texts of these important books while presenting them in durable paperback editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
