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.

"Contemporary theory of international politics faces a twofold problem: the critical engagement with legacies of national power politics in connection to 20th Century International Relations and the regeneration of notions of humanity. This book contributes to this engagement by a genealogy of thoughts on war, peace, and ethics"--Provided by publisher.

Critical and scientific realism have emerged as important perspectives on international relations in recent years.

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.

Realism is one of the core theories within the field of international relations, and it generally posits a state system characterized by anarchy where states act in what they perceive to be their own self interests. It is a controversial theory, and it has many opponents. Yet effective debate among realists and those who identify with other schools of thought has diminished dramatically over time. As Patrick James argues in Realism and International Relations, scholars in the field have become dissatisfied with results from exchanges in words alone. He contends that translation of the vast amount of information in the field into knowledge requires a greater emphasis on communication beyond the use of text. Given the challenges posed by existing and intensifying information overload, he develops a new model that relies on the graphic representation of analytical arguments. As James explains, realist scholarship in the post-World War II era is the natural domain for the application of systemism, a graphic form of expression with straightforward rules for portrayal of analytical arguments, notably cause and effect within theories. Systemism goes beyond prior iterations of systems theory to offer a visualization technique borrowed and adapted from the philosophy of science. Systemist graphics reveal the shortcomings, contributions and potential of realism. These visualizations, which focus on realist theories about war, are intended to bring order out of what critics tend to describe, with some justification, as chaos. In sum, a graphic turn for realism in particular and international relations in general is essential in order to achieve the scientific progress that otherwise is likely to remain elusive. A major theoretical work by an eminent scholar, this will be of interest to all theorists focusing how the international system of states actually functions.

1. The realist tradition

Stefano Guzzini's study offers an understanding of the evolution of the realist tradition within International Relations and International Political Economy. It sees the realist tradition not as a school of thought with a static set of fixed principles, but as a repeatedly failed attempt to turn the rules of European diplomacy into the laws of a US social science. Realism in International Relations and International Political Economy concentrates on the evolution of a leading school of thought, its critiques and its institutional environment. As such it will provide an invaluable basis to anyone studying international relations theory.
