For political realists, legitimacy is a central requirement for the desirability of political institutions. Their detractors contend that it is either descriptive, and thus devoid of critical potential, or it relies on some moralist value that realists reject. We defend a functionalist reading of realist legitimacy: descriptive legitimacy, that is, the capacity of a political institution to generate beliefs in its right to rule as opposed to commanding through coercion alone, is desirable in virtue of its functional role. First, descriptive legitimacy plays an evaluative role: Institutions can fail to convince citizens that they have a right to rule and can be ranked by how well they do so. Second, descriptive legitimacy plays a normative role, because if an institution fails to convince subjects of its right to rule, this gives them a reason not to comply with its directives, even if it satisfies philosophers’ standards for possessing such right.

Disagreement among philosophers over the proper justification for political institutions is far from a new phenomenon. Thus, it should not come as a surprise that there is substantial room for dissent on this matter within democratic theory. As is well known, instrumentalism and proceduralism represent the two primary viewpoints that democrats can adopt to vindicate democratic legitimacy. While the former notoriously derives the value of democracy from its outcomes, the latter claims that a democratic decision-making process is inherently valuable. This article has two aims. First, it introduces three variables with which we can thoroughly categorise the aforementioned approaches. Second, it argues that the more promising version of proceduralism is extrinsic, rather than intrinsic, and that extrinsically procedural accounts can appeal to other values in the justification of democracy without translating into instrumentalism. This article is organised as follows. I present what I consider to be the ‘implicit view’ in the justification of democracy. Then, I analyse each of the three variables in a different section. Finally, I raise an objection against procedural views grounded in relational equality, which cannot account for the idea that democracy is a necessary condition for political legitimacy.
