Since the end of the Cold War, there has been increasing interest in the global dimensions of a host of public policy issues - issues involving war and peace, terrorism, international law, regulation of commerce, environmental protection, and disparities of wealth, income, and access to medical care. Especially pressing is the question of whether it is possible to formulate principles of justice that are valid not merely within a single society but across national borders. The thirteen essays in this volume explore a range of issues that are central to contemporary discussions of global politics. Written by prominent philosophers, political scientists, economists, and legal theorists, they offer valuable contributions to current debates over the nature of justice and its implications for the development of international law and international institutions.
