This paper addresses a neglected question in republican political philosophy: what are the conditions for a set of arguments to be considered republican? While republicanism traditionally confers a fundamental role to the democratic ideal of participation in decision-making, recent contributions argue that freedom could be promoted by facilitating exit where possible. The strong version of the latter argument states that when exit is possible, it constitutes the most important contribution to republican freedom, and it preserves the goal of isolating individual (...) choices, i.e. it precludes collective decision-making from interfering with them, and so it intends to limit the scope of public concern considered legitimate. I examine this argument to discuss the boundaries and varieties of republicanism: (i) the boundaries establish that an argument should be couched and substantively articulated in distinctively republican terms; (ii) the strong version of the exit argument does not fall within the boundaries because it is in tension with core republican commitments to self-government and civic virtues; (iii) once we abide by the boundaries we may encounter a diversity of proposals differing on the more concrete level of institutional design and empirical assumptions – these are the varieties of republicanism.
