This book evaluates the claim that in order to explore the changing social foundations of global power relations today, we need to include in our analysis an understanding of global civil society, particularly if we also wish to raise ethical questions about the changing political and institutional practices of transnational governance. Bridging the normative concerns of political theorists with the historical and institutional focus of scholars of international relations and international political economy, this book is of broad interest to students and researchers concerned with international relations, civil society, global governance and ethics.
