"A cohesive, articulate and powerful plea in favour of a deep transformation of the world order." Survival A comprehensive study of the phenomenon, illustrated by well-chosen examples." Political Studies Review "Held articulates a number of feasible reforms, sustained by universal ethical and political commitments, that can be undertaken to address specifically global problems. His deft and clear-eyed rendering of the changing trajectory of cosmopolitan thought makes this book an informative introduction to the topic." Choice "David Held formulates a robust cosmopolitanism and imaginatively applies it to the great faults of our international order: its lack of effective environmental-protection, peacekeeping, and global-finance regimes. The pragmatic reforms he envisions would undoubtedly make our world more democratic and just." Thomas Pogge, Yale University "David Held's new book gives the lie to those who regard cosmopolitanism as a vague set of indeterminate woolly ideals. This is as grounded and as comprehensive an account of the cosmopolitan agenda as one could wish for." Jeremy Waldron, New York University Law School "In a world beset by financial crisis, nuclear proliferation and climate change, our capacity for international co-operation and solidarity has rarely seemed so inadequate, or the need for them more urgent. In this book, David Held provides a powerful and persuasive analysis of this paradox of our times, and how cosmopolitan principles offer a way to overcome it." Andrew Gamble, University of Cambridge "National realpolitik is dead, long live cosmopolitan realpolitik! David Held's robust development and defence of cosmopolitanism provides a masterful framework for the urgent reorientation required - both political and cognitive - by an unevenly interconnected world." Ulrich Beck, University of Munich
