Understanding the ancient and long sidelined concept of cosmopolitanism has suddenly found a fresh impetus and urgency. Globalization, international migration, multiculturalism and global social movements, as well as atrocities committed by those with narrow religious and ethnic identities,have led to reposing of two basic cosmopolitan questions: Can we ever live peacefully with one another? What do we share, collectively, as human beings? The term cosmopolitanism has attracted many understandings and uses over the years. Covering the global, national, social and personal levels of analysis, the authors consider the multiple meanings of the term in the past and in the present and develop new ways of conceiving cosmopolitanism.Through challenging old assumptions and advancing new analytical frameworks, the collection provides a full and representative set of views on the nature, definition and prospects of cosmopolitanism. Written by eminent scholars and publicly recognised intellectuals from a variety of cultural backgrounds, this book is the most comprehensive account of the theory and practice of cosmopolitanism yet attempted.
