This book is an informative addition to the literature responding to the current renewed interest in the history of the discipline. By taking as its temporal scope the seventeenth to the twentieth centuries, it constitutes a healthy reminder that our contemporary theorizing on IR rests on a long-developing pattern of inquiry and that the most recent expression of an observation may not constitute the most profound or apt formulation. By taking as its geographical/cultural/political scope the writings of British international thinkers, it recognizes the need for focus in such an investigation, and it provides a ready-made response to the inevitable special pleaders who would ask, But where is my favorite writer? Given the increasing attention paid to the contributions of the English School to IR theory, it is both a timely intervention and a valuable resource. - David Clinton, Professor of Political Science, Baylor University
