Edited by Ward (Baylor Univ.), this volume provides a diverse, erudite collection of 14 essays on aspects of cosmopolitanism in Western political thought throughout history. Perspectives on the importance of this mode of thinking from the Roman Republic to the modern EU are provided. Given the increased criticism of cosmopolitanism in contemporary politics (in some cases even its rejection), as witnessed in both the UK Brexit debate and Trump’s US policy discourse, the value of a "cosmopolitan ... worldview" is shown to be deserving of reevaluation. The volume touches on global issues related to contemporary citizenship, and readers may conclude that a shared international mission can best be attained by looking to the inherited tradition. . . The chapters on Cicero (first century BCE) and Althusius (1557–1638) are exemplary. . . the book provides a useful survey and encourages deeper exploration—even "conversation"—between the advocates and the critics of cosmopolitanism. Summing Up: Recommended. Graduate students, faculty, and professionals.
