Hedley Bull (1932 - 1985) - The Anarchical Society: A Study of Order in World Politics (1977)
The "Anarchical Society" is one of the masterworks of political science and the classic text on the nature of order in world politics. Originally published in 1977, it continues to define and shape the discipline of international relations. This edition has been updated with a new, interpretive foreword by Andrew Hurrell. Bull explores three fundamental questions: What is order in world politics? How is order maintained in the contemporary states system? What alternative paths to world order are desirable and feasible? Laws and institutions, Bull points out, shift and change over time. The Anarchical Society addresses the unwritten rules which have allowed the international order to exist across the ages.
