This book takes up the tension between globalization and community in order to articulate a new theory of global justice. Although the process of globalization is not new, its current manifestation and consequences are. At the same time, there is a growing recognition of the importance of community, identity and belonging. These two facts have generally been understood to be fundamentally in tension, both theoretically and descriptively. This book seeks to resolve this tension, and then draw out the implications for a theory of global justice and an understanding of the value and purpose of community. Importantly, the book argues, not only does an acceptance of the significance of the fact of globalization and the importance of community call for cosmopolitan duties and obligations, but it also calls into question the legitimacy and justification of the traditional nation-state. Aimed primarily at scholars working on issues related to political philosophy, globalization and global justice, the book will appeal to readers in law, politics, philosophy, and sociology.
