Abstract

The history of what we now term international relations theory is as rich and as complex as any area in the history of political thought. Yet in the last few decades one particular type of political philosophy has come to be almost unambiguously associated with liberal international relations theory. The dominance of Kantian cosmopolitanism in contemporary liberal international relations theory is quite remarkable. Its position is challenged, within liberalism, only by the utilitarian cosmopolitanism of thinkers such as Peter Singer and, from outside the liberal tradition, by communitarians such as Michael Walzer or Alasdair MacIntyre. At least, this is how the debate is portrayed in the current literature. In this article I want to suggest that the biggest challenge to Kantian cosmopolitanism comes from within the neo-Kantian tradition.
