This book investigates how international relations theorists can better equip themselves to determine the state of scholarly work in their field. It takes as its starting point Imre Lakatos's influential theory of scientific change, and in particular his methodology of scientific research programs (MSRP). It uses MSRP to organize its analysis of major research programs over the last several decades and uses MSRP's criteria for theoretical progress to evaluate these programs. The contributors appraise the progress of institutional theory, varieties of realist and liberal theory, operational code analysis, and other research programs in international relations.

Bridges and Boundaries offers a conversation between what might loosely be described as traditionalist diplomatic and military historians, and political scientists who employ qualitative case study methods to examine international relations. The book opens with a series of chapters discussing differences, commonalities, and opportunities for cross-fertilization between the two disciplines.

Bridges and Boundaries explores how historians and political scientists can learn from one another and illustrates the possibilities that arise when open-minded scholars from different disciplines sit down to talk.
