Realism, Liberalism and Non-ideal Theory Or, Are there Two Ways to do Realistic Political Theory?

The charge that contemporary political theory has lost touch with the realities of politics is common to both the recent ideal/non-ideal theory debate and the revival of interest in realist thought. However, a tendency has arisen to subsume political realism within the ideal/non-ideal theory debate, or to elide realism with non-ideal theorising. This article argues that this is a mistake. The ideal/non-ideal theory discussion is a methodological debate that takes place within the framework of liberal theory. Realism, contrary to several interpretations, is a distinct and competing conception of politics in its own right that stands in contrast to that of liberal theory. While the two debates are united in a sense that contemporary liberal theory needs to be more realistic, they differ significantly in their understanding of this shortcoming and, more importantly, what it is to do more realistic political theory.
