The development of a fully fledged European Public Sphere is seen by many as the solution to the legitimation crisis the European Union is suffering today. It is conceived as a space in which a Europe-wide debate about the current economic, social and political crises can take place and through which solutions can be developed.This book proposes a new multi-disciplinary approach to discuss the European Public Sphere, arguing that it should be approached as a complex and interlinking concept, considering issues such as identity, citizenship building and multi-level governance structures and actors, and that it should not be analysed merely from the traditional perspectives of information and communication policies.The volume presents both academic papers and more policy-oriented contributions, offering perspectives from scholars, politicians, consultants and administrators to give the reader a truly multidisciplinary understanding of the European Public Sphere.
