In this article I defend a new argument against moralist theories of legitimacy and in favour of realist theories. Moralist theories, I argue, are vulnerable to ideological and wishful thinking because they do not connect the demands of legitimacy with the interests of rulers. Realist theories, however, generally do manage to make this connection. This is because satisfying the usual realist criteria for legitimacy – the creation of a stable political order that transcends brute coercion – is usually necessary for (...) rulers to preserve their rule.

Political realism is characterised by fidelity to the facts of politics and a refusal to derive political judgments from pre- political moral commitments. Even when they are not taken to make normative theorising impossible or futile, those characteristics are often thought to engender a conservative slant, or at least a tendency to prefer incremental reformism to radicalism. I resist those claims by distinguishing between three variants of realism—ordorealism, contextual realism, and radical realism—and contrasting them with both non-ideal theory and utopianism. (...) I then develop a version of radical realism as a form of debunking and vindicatory genealogy. Even though this new approach eschews both feasibility constraints (unlike non-ideal theory) and prescriptions about the ideal society (unlike utopianism), I show how it has more radical potential than morality-driven (and hence often ideological) political theory, and how it supports both open-ended, radical social critique and concrete forms of prefigurative political action.
