A Kantian Conception of Global Justice

I start this paper by addressing Kant’s question why rightful interactions require both domestic public authorities (or states) and a global public authority? Of central importance are two issues: first, the identification of problems insoluble without public authorities, and second, why a domestic public monopoly on coercion can be rightfully established and maintained by coercive means while a global public monopoly on coercion cannot be established once and for all. In the second part of the paper, I address the nature of the institutional structure of individual states and of the global authority. Crucial here, I argue, is Kant’s distinction between private and public right. Private right concerns rightful relations between individual legal subjects, where public right concerns their claims on their public institutions. I propose that the distinction between private and public right should be central to liberal critiques of current legal and political developments in the global sphere.
