Critical and scientific realism have emerged as important perspectives on international relations in recent years. The attraction of these approaches lies in the claim that they can transcend the positivism vs postpositivism divide. This book demonstrates the vitality of this approach and the difference that 'realism' makes.

International Relations and Scientific Progress contends that a theory focusing on the structure of the international system explains a wider and more interesting range of events in world politics than other theories. Such theorizing appears to be out of favor as the result of the apparent failure by structural realism, the most prominent system-level theory over the last two decades, on any number of fronts--most notably an inability to anticipate the ending of the Cold War and its aftermath. This new book is put forward as the most comprehensive and innovative theoretical work on paradigms in international relations since the publication of Theory of International Politics, which created structural realism, more than two decades ago. With appropriate revisions, however, structural realist theory can compete effectively and reclaim its primacy. The first part of International Relations and Scientific Progress assesses the meaning of progress in the discipline of international relations, a process that culminates in the creation of a new concept, the scientific research enterprise. The second part reviews structural realism within that context and identifies a lack of connection between theory and research that links power-based indicators to international conflict, crisis, and war. This part of the book makes the case for an elaboration of structural realism by showing that a system-level theory based on structure has great unrealized explanatory potential. By comparison, the current overwhelmingly research oriented agenda on state dyads imposes severe limitations on understanding that are not currently appreciated. Part Three sums up the work and explores new directions, most notablyas related to empirical testing of an elaborated version of structural realism that focuses on both continuity and change in the international system.

1. The realist tradition

This volume ws the winner of The International Studies Association Theory Section Book Award 2013, presented by the International Studies Association and The Yale H. Ferguson Award 2012, presented by International Studies Association-Northeast. There are many different scientifically valid ways to produce knowledge. The field of International Relations should pay closer attention to these methodological differences, and to their implications for concrete research on world politics. The Conduct of Inquiry in International Relations provides an introduction to the philosophy of science issues and their implications for the study of global politics. The author draws attention to the problems caused by the misleading notion of a single unified scientific method, and proposes a framework that clarifies the variety of ways that IR scholars establish the authority and validity of their empirical claims. Jackson connects philosophical considerations with concrete issues of research design within neopositivist, critical realist, analyticist, and reflexive approaches to the study of world politics. Envisioning a pluralist science for a global IR field, this volume organizes the significant differences between methodological stances so as to promote internal consistency, public discussion, and worldly insight as the hallmarks of any scientific study of world politics. This important volume will be essential reading for all students and scholars of International Relations, Political Science and Philosophy of Science.

Scientific realism is at the core of the contemporary philosophical debate on science. This book analyzes new versions of scientific realism. It makes explicit the advantages of scientific realism over alternatives and antagonists, contributes to deciding which of the new approaches better meets the descriptive and the prescriptive criteria, and expands the philosophico-methodological field to take in new topics and disciplines.
