These essays on moral issues in international affairs focus on a number of problems that generate in- tense interest in the post-Vietnam War era-the ba- sis of rules for the conduct of war, the significance of national boundaries and the nature of a state's right not to be interfered with by outsiders, the foundations of international property rights, and the requirements of international distributive justice. Is moral reflection capable of supplying answers to these questions? "Yes," argues Marshall Cohen in an introductory chapter that offers a convincing an- swer to the pervasive skepticism concerning the possibility of making moral judgments about inter- national affairs. All of the essays in this book-with the exception of the extended excerpts from Michael Walzer's Just and Unjust Wars were previously published in Philosophy & Public Affairs.

Because of the unusual demand for reprints of var- ious articles that originally appeared in the journal Philosophy & Public Affairs, Princeton University Press from time to time issues original paperback editions which bring together articles on a specific subject. Each of these editions is published as part of the regular program of Princeton Paperbacks and is identified as "A Philosophy & Public Affairs Reader." This book is also available in cloth.
