Epistemological Restraint—Revisited

THOMAS NAGEL has argued that ‘true liberalism’ excludes appeals to conceptions of the good in political argument. According to Nagel, liberalism's impartiality is grounded not in skepticism but, rather, in its commitment to ‘epistemological restraint.’ As he puts it, ‘We accept a kind of epistemological division between the private and the public domains: in certain contexts I am constrained to consider my beliefs merely as beliefs rather than as truths, however convinced I may be that they are true , and that I know it.’ Nagel's notion of epistemological restraint has been roundly criticized by perfectionist liberals and advocates of liberal neutrality alike. In fact, even Nagel has come to reject the epistemological argument—in part, because of the epistemological asymmetry that it presupposes. In this paper, I offer an answer to Nagel's critics, one that makes the notion of epistemological asymmetry coherent. In so doing, I show how to defend liberal neutrality without embracing skepticism. I structure the paper in the following way: Section II lays out the critique of epistemological restraint; Section III defends the coherence of this notion; and Section IV considers an objection to the analysis developed in Section III.
