Reasonability,normativity, and the cosmopolitan imagination: Arendt,Korsgaard, and Rawls

In this essay I consider the normative implications of the notion of reasonability for the construction of an idea of public reason that is cosmopolitan in scope. First, I consider the argument for the distinction between reason and reasonability in the work of Sibley and Rawls. Second, I evaluate the normative implications of reasonability through a consideration of Korsgaard's recent work. Third, I argue for a notion of reasonability that moves us beyond a Kantian concept of autonomy through a consideration of the relationship between reasonability and judgment vis-à-vis Arendt's work on Kant's Third Critique. Finally, I argue for a cosmopolitan appropriation of the notion of reasonability based on Kant's notion of the aesthetic idea. The latter argument relaxes the bonds of public reason, moving us beyond the domain of ethnocentricism.
