Educating citizens to public reason : what can we learn from interfaith dialogue?

Abstract

John Rawls’s political liberalism demands that reasonable citizens comply with the duty of civility, which limits the justification of state action to public reasons. However, many religious citizens in liberal democratic societies reject the exclusion of religious reasons from public debate. What can be done to encourage these citizens to endorse public reason? Rawls proposes the idea of reasoning from conjecture (RC), i.e. directly engaging with someone’s comprehensive doctrine and showing them that such a doctrine actually supports public reason. In this article, we argue that reasoning from conjecture faces serious objections and that interfaith dialogue (ID) provides a better and more effective tool to encourage religious citizens to endorse public reason. More specifically, ID provides support to public reason by (i) relying on the principles of equality, sincerity and self-criticism, which are also central to public reason; (ii) leading participants to de-parochialize religion; and (iii) promoting tolerance. Moreover, ID avoids the main objections faced by RC, which undermine the latter’s morality and effectiveness.
