This essay demonstrates that Niccolò Machiavelli’s political thought addresses the deficiencies of two opposite poles of contemporary democratic theory: As do formal or minimalist approaches, he specifies electoral mechanisms for elite control; and similar to substantive or civic culture approaches, he encourages more direct and robust modes of popular participation. On these grounds, I cull from Machiavelli’s Discourses a theory of democracy in which the populace selects the elites who will hold office but also constantly patrols them through extraelectoral institutions and practices, such as the tribunes of the people, public accusations, and popular appeals. Machiavelli adds to these institutional features of popular government an important cultural dimension: The people should despise and mistrust elites, and they should actively confront the injustice that elite governing inevitably entails. Finally, I explore the ramifications of this theory for debates over elite accountability in contemporary democratic theory.
