Most interpreters who have taken an interest in Rousseau’s nationalism have looked beyond his Social Contract. This seems fitting, for Rousseau’s Considerations on the Government of Poland, Constitutional Project for Corsica, and Discourse on Political Economy explicitly discuss the role of nationality and the distinctiveness of national identity. By way of contrast, the Social Contract is often cited as a work of ideal theory, less concerned with the empirical, sociological contingencies of actual nations and more focused on normative questions about the best political community. This chapter suggests that this standard interpretation of the Social Contract discounts the significant role played by extant, prepolitical peoples. Rather than a purely abstract contract among previously unaffiliated individuals, as per Thomas Hobbes, a closer reading reveals the ontological and historical primacy of peoples in Rousseau’s political theory.
