Pluralism, federalism, and two levels of the original position

This paper examines John Rawls’s concept of the original position at both the domestic and international levels, focusing on the pluralist structure of the Society of Peoples and its implications for cooperation among societies with fundamentally different conceptions of justice. Using the example of Kazanistan—a fictional Islamic society recognized as “decent” in Rawls’s framework—I demonstrate that the coexistence of liberal and non-liberal peoples within the Society of Peoples is made possible by mechanisms drawn from classical federalist philosophy, especially as developed by Althusius and Montesquieu. Rather than requiring the subordination of local legal and moral traditions to liberal universalism, Rawls’s international model allows each people to interpret shared principles in accordance with their own comprehensive doctrines, thereby preserving internal autonomy alongside mutual accountability. This federalist structure ensures that deeply divergent conceptions of law and justice—such as those of Islamic Kazanistan and liberal societies—can participate equally in a common international order, provided they meet substantive criteria of decency. The result is a genuinely pluralist and federative model of global cooperation that can be described as a synthesis of liberalism and communitarianism, in which the principles of justice are not simply imposed from a liberal perspective, but are subject to legitimate interpretation by all decent peoples from within their own comprehensive doctrines.
