Gunther Teubner is Professor of Private Law and Legal Sociology at Goethe University, Frankfurt
‘For a number of years now Gunther Teubner has been one of the most important and visible figures in the sociology of law. His concept of “societal constitutionalism” has largely shaped the perspective of constitutional sociology. In these essays he deploys the heuristic power of systems theory to argue against a purely political constitutionalism and in favour of re-conceiving constitutionalisation across social fields. The collection represents a highly significant contribution to one of the key theoretical debates of our time.’ Emilios Christodoulidis, Chair of Jurisprudence, School of Law, University of Glasgow -- .
