Thomas Kuhn and international relations theory: Realism in 'crisis'

In 2012, the University of Chicago Press published a special fiftieth anniversary edition of Thomas Kuhns influential book, The Structure of Scientific Revolutions. Kuhn, who died of lung cancer in 1996, was a physicist trained at Harvard University and is best known for his work on the history and philosophy of science. His interpretation of the evolution of science and the concept of paradigm change have had a major impact on our understanding of intellectual life, both in the physical sciences and in the social sciences. This paper briefly reviews Kuhns approach, and then applies it to an analysis of the current state of International Relations theory in a critique of Realism. My argument is that Realism, as what Kuhn would call normal science in International Relations theory, is in crisis because of its inability to explain a growing number of anomalies, which in turn can be better explained by a different paradigm, Cooperative Security.
