How do ordinary people identify themselves as part of a group? By what means do they express a largely unspoken understanding of themselves in society? This special issue on new social imaginaries examines emergent forms of solidarity and collective identity in a global context. The essays explore how local cultural forms and global social movements contribute to the making and unmaking of imagined collective identities. Contributors to this collection include major voices in the fields of philosophy, critical literature, sociology, anthropology, and communication studies. The articles consider how people conceive of and categorize themselves as part of a cohesive group under the multiple rubrics of the public and counterpublic, nation, ethnos, civilization, genealogy, democracy, and the market. Many of the essays are situated in specific national and cultural sites such as Africa, Australia, 18th-century England, the European Union, India, and Turkey. Others examine the intersections of global financial markets and democratic institutions. As a whole, New Imaginaries suggests a new way of synthesizing economic, political, and cultural approaches to social life.
