The study of Cosmopolitanism has been transformed in the last 20 years and the subject itself has become highly discussed across the social sciences and the humanities. The Ashgate Research Companion to Cosmopolitanism pursues distinct theoretical orientations and empirical analyses, bringing together mainstream discussions with the newest thinking and developments on the main themes, debates and controversies surrounding the subject. The contributions are grouped into three parts, each reflecting a different analytical focus within a variety of intellectual disciplines and methodological approaches. Part I (Cultural Cosmopolitanism) is primarily concerned with the empirically-grounded aspects of cosmopolitanism which are apparent in mundane practices and lifestyle options on the micro-scale of daily interactions. It focuses on the outlooks and lived experience of ordinary individuals and groups in concrete situational contexts and social structures. Part II (Political Cosmopolitanism) sets out the main topics and issues dealt with by scholars writing within the tradition of political cosmopolitanism. Addressing timely issues such as human rights, global justice, and global democracy, it focuses on Cosmopolitanism as an ethico-political ideal and a political project to devise new forms of supranational and transnational governance. Part III (Debates) reflects the major debates and controversies on the subject and deliberately eschews any bland consensus to instead foreground the key arguments and lively intellectual discussions in play across disciplinary divisions. Featuring contributions from key thinkers in the field, including Ulrich Beck, David Held and Martha Nussbaum, this comprehensive volume will be a valuable resource for all academics and students working within this area of study.
