"In his impressive book Jiří Přibáň tackles the controversies currently surrounding the key concept of sovereignty in a truly magisterial way. Not only does Přibáň provide an in-depth interdisciplinary account of sovereignty, but also, in a veritable tour de force, he develops a novel approach based on autopoeitic systems theory that repositions sovereignty as a semantic connector between law and politics. Přibáň's hypothesis deserves careful consideration by anyone seeking to overcome the impasse between an obsolete nation-state based conception of sovereignty and ill-fitting transnational counterparts." - Michel Rosenfeld, Benjamin N. Cardozo School of Law, USA "If popular sovereignty still holds a key to the political imaginary of the age, despite its continued erosion in the face of the supposed givens of economic science, the aim of this fascinating book is to bring the concept back to the fore in all its productive ambivalence. Přibáň brings an impressive knowledge of systems-theory to navigate the field of post-sovereignty in an incisive analysis of the dialectic between the persistent political and legal semantics of sovereignty and the changes in the underlying structures of political organization in a globalized world."- Emilios Christodoulidis, University of Glasgow, UK"This book provides an important reconstruction of theories of sovereignty and an original discussion of their position in current legal and political realities. It contains a distinctive argument in a generally crowded field of research, and it shows how systems-theoretical approaches, placing emphasis on semantics and self-description, can be applied to illuminate theoretical constructions in law and politics." - Christopher Thornhill, Manchester University, UK
