Public Reason and the Moral Foundation of Liberalism

Abstract

AbstractI argue against Rawls’s freestanding conception of liberalism. On my view, the moral foundation of liberalism can be defended in one of three ways: (1) as a conception one accepts as a result of one’s affirmation of political liberalism, (2) as a conception one must affirm as a presupposition for political liberalism, or (3) as a philosophical truth about practical reason and persons. The first option makes it impossible to distinguish a moral consensus from a modus vivendi. The second renders the moral foundation of liberalism dogmatic because it affirms a moral foundation for which no justification is provided. Since there are good reasons for rejecting (1) and (2), that leaves option (3). I argue that (3) should be the preferred option for liberals who advance liberalism as a political doctrine with a moral foundation.
