Given its object of study, one would think that the field of International Relations would be a particularly cosmopolitan and ecumenical discipline. In many ways it is. But in some respects it resembles a collection of warring tribes. This has probably declined somewhat since the Big Debates of the 1990s—the Neo-Neo Debate, epistemology wars between neo-positivists and ‘critical’ theorists—which still provide many of the key readings for students of IR theory. But these Big Debates didn’t really end in a definitive victory for one side. They mostly gave way to a Cold Peace amongst relatively insular scholarly communities. Well they maybe did – it’s hard to know for sure.
One of the interesting phenomena about how IR scholars talk about their field and their tribe is that they often refer to it as ‘mainstream’. Often, this is done by those who feel they are outside of the mainstream. (Interestingly, there does not appear to be an accepted metaphor to refer to those who are not part of the mainstream – backwaters? Counter-currents?) But what does this mainstream consist of?
