Understanding world politics today means acknowledging that the state is no longer the only actor in international relations. The interstate system is increasingly challenged by new transnational forces and institutions: multinational companies, cross-border coalitions of social interest groups, globally oriented media, and a growing number of international agencies. These forces increasingly influence interstate decisions and set the agenda of world politics. Though these phenomena have been discussed in the recent literature of international relations, little attention has been given to their impact on political life within and between communities. This book aims to explore the changing meaning of political community in a world of regional and global social and economic relations. The authors of the essays in this volume, who reflect a variety of academic disciplines, reconsider some of the key terms of political association, such as legitimacy, sovereignty, identity, and citizenship. Their common approach is to generate an innovative account of what democracy means today and how it can be reconceptualized to include subnational as well as transnational levels of political organization. Inspired by Immanuel Kant's cosmopolitan principles, the authors conclude that favorable conditions exist for a further development of democracy-locally, nationally, regionally, and globally.
