This collection brings together an unusually distinguished and diverse group of theorists of global politics, political geography, and international political economy who reflect on the concept of political space. Already familiar to political geographers, the concept of political space has lately received increased attention, arising out of the need for new ways of thinking about and describing the actors, structures, and processes that shape politics and patterns of governance in today's complex, post-Cold War world. The essays explore the frontiers of the field of global politics, and each deals imaginatively with some aspect of political space. Although the participants may be loosely classified as realists, neo-realists, constructivists, and postinternationalists, the essays are not fitted to the usual theoretical pigeonholes. What they do share is a continued faith in empirical research, and a collective sense of discovery.
