International theory in a post-paradigmatic era: From substantive wagers to scientific ontologies

Concerns about the end of International Relations theory pivot around at least three different issues: the fading of the ‘paradigm wars’ associated with the 1990s and early 2000s; the general lack of any sort of ‘great debate’ sufficient to occupy the attention of large portions of the field; and claims about the vibrancy of middle-range theorizing. None of these are terribly helpful when it comes to assessing the health of International Relations theory. We argue that international theory involves scientific ontologies of world politics: topographies of entities, processes, mechanisms, and how they relate to one another. Understood this way, the state of International Relations theory looks strong: there is arguably more out there than ever before. Ironically, this cornucopia helps explain concerns regarding the end of International Relations theory. In the absence of a ‘great debate,’ let alone ways of organizing contemporary International Relations theory, this diversity descends into cacophony. We submit that three major clusters of international theory are emerging: choice-theoretic, experience-near, and social-relational. These clusters map onto two major axes of contention: (1) the degree that actors should be treated as autonomous from their environment; and (2) the importance of thickly contextual analysis. These disputes are both field-wide and high-stakes, even if we do not always recognize them as such.
