“This book is an important contribution to scholarship on the disciplinary history of International Relations and of the postwar human sciences. Essential reading.”— Duncan Bell, University of Cambridge“An excellent source of primary material for students of IR, the history of social science development, links between knowledge and power, and the role of elite think tanks and their networks. It also documents a core ambiguity if not contradiction in understandings of what IR should be and what it should be for between those concerned with decision making and policy and those who viewed scholarship as one step removed from power itself.”— —Inderjeet Parmar, City, University of London
