Chapter 2 presents the conceptual transformation of republicanism that Rousseau operated while responding to Montesquieu’s challenges. In his writings, republicanism moved from an elitist theory based on virtuous self-sacrifice to an inclusive theory based on popular sovereignty and the rational interest of citizens. Rousseau developed a theory of republican citizenship as a shared intention toward creating and maintaining a community of free and equal beings—an inclusive theory of sharing freedom. Yet Rousseau’s theory has important shortcomings that plagued French republicanism after him. On the one hand, it presented a rational project of sharing equal freedom among all, but on the other, it emphasized particularism and nationalism as conditions of its realization.
