Abstract
Joseph Raz's famous theory of authority is grounded in three claims about the nature and justification of authority. According to the Preemption Thesis, authoritative directives purport to replace the subject's judgments about what she should do. According to the Dependence Thesis, authoritative directives should be based on reasons that actually apply to the subjects of the directive. According to the Normal Justification Thesis (NJT), authority is justified to the extent that subjects are more likely to comply with right reason by following the authority's directives than by following their own judgments about what right reason requires.1In this article, I consider a number of ways in which NJT might be construed as a justification for authority. First, I evaluate NJT construed as a principle that would provide a practical justification for an individual to accept or recognize a particular person or persons as a preemptive authority. Second, I evaluate NJT construed as a principle that describes the conditions under which a state or legal system is morally legitimate. I argue that NJT is true under none of these interpretations.2
