This essay criticizes Joseph Raz’s service conception of authority on the basis of its knowability condition. The condition states that for agents to be justified in following authoritative directives, they must be able to know (i.e., form reliable beliefs) that the authority issuing the directives is in fact legitimate. The distinction between belief and acceptance, the problem of incommensurable values, and the vagueness surrounding right reason are shown to be three problematic areas that affect the knowability condition.
