In Partisanship and Political Liberalism in Diverse Societies I examine political parties and partisanship within the context of John Rawls’s theory of political liberalism. I argue that parties and partisanship are vital to Rawls’s political liberalism, since they offer a distinctive and crucial contribution to the process of public justification that is central to it, which combines the articulation of public reasons with the channelling into the public political realm of the particular values and conceptions of the good emerging from (...) parties’ specific constituencies. Furthermore, I argue, partisanship generates a special kind of political obligations, and this further contributes to state legitimacy under conditions of reasonable pluralism. In this paper, I respond to three commentators who have raised important criticisms against my argument. More specifically, Section 1 provides a response to Lea Ypi’s argument that my normative account of partisanship wrongly presupposes that existing liberal societies are reasonably just. Section 2 answers Daniel Weinstock’s concerns regarding the plausibility and internal consistency of my account of partisan political obligations. Finally, Section 3 addresses Kevin Vallier’s criticisms, which challenge my account of public reason and propose an alternative one. (shrink)
