The democratic boundary problem and social contract theory

How to demarcate the political units within which democracy will be practiced? Although recent years have witnessed a steadily increasing academic interest in this question concerning the boundary problem in democratic theory, social contract theory's potential for solving it has largely been ignored. In fact, contract views are premised on the assumption of a given people and so presuppose what requires legitimization: the existence of a demarcated group of individuals materializing, as it were, from nowhere and whose members agree among themselves to establish a political order. In order to fill this gap in social contract theory, a distinction is made between three kinds of contract views: Lockean political voluntarism, contractarianism, and contractualism. Each of these views can be (re)interpreted in such a way that it offers a democratic solution to the boundary problem. Ultimately, however, a Rawisian interpretation of the contractualist solution is defended.
