 Although the idea of public reason is primarily a view about the justification of moral or political rules, it may have other important social functions. Paul Weithman suggests that public reason also plays an essential role—at least in Rawls’s Political Liberalism—in establishing mutual assurance with regard to a commitment to a public conception of justice amongst citizens who are deeply divided about religious, moral, and philosophical matters (Weithman 2010, 326–335). On this view, citizens need to be assured that others are committed to justice in order to know that acting from their own sense of justice is not something to regret. Without this assurance, citizens might reasonably worry that acting justly conflicts too deeply with their narrow conception of the good, in which case society would not be stable and well-ordered in Rawls’s senses (see also Hadfield and Macedo 2012; Macedo 2010, Other Internet Resources).
