 Others, most notably Gaus, argue that the idea of public reason follows from certain basic features of our everyday moral practices and reactive attitudes, along with certain claims about the nature of reasons (Gaus 2011). On this view, social morality involves a particular kind of interpersonal relationship; one where we claim the standing to make demands of others, and where, under the right conditions, we acknowledge the standing of others to make demands on us (Gaus 2011, 184). But for this sort of relationship to exist, we must believe that when we make moral demands of others, those others have sufficient reasons to comply with our demands—if they did not have sufficient reasons to comply, then the reactive attitudes that form an essential part of the interpersonal relationship of social morality would cease to make sense (Gaus 2011, 205–232). If, as Gaus maintains, different people have different reasons depending on their differing epistemic positions and sets of justified beliefs, the practice of making moral demands of others must involve public reason: the moral demands we make on others must be justifiable to those others by appeal to reasons they have, and not simply by appeal to the truth as we see it.
