Abstract

What makes an ``ought'''' claim authoritative? What makes aparticular norm genuinely reason-giving for an agent? This paper arguesthat normative authority can best be accounted for in terms of thejustification of norms. The main obstacle to such a theory, however, isa regress problem. The worry is that every attempt to offer ajustification for an ``ought'''' claim must appeal to another ``ought''''claim, ad infinitum. The paper argues that vicious regress canbe avoided in practical reasoning in the same way coherentists avoid theproblem in epistemology. Norms are justified by their coherence withother norms.
