This paper is divided into two parts. In the first one I distinguish between weak and strong Anti-Archimedeanisms, the latter being the view that metaethics, just as any other discipline attempting to work out a second-order conceptual, metaphysical non-committed discourse about the first-order discourse composing normative practices, is conceptually impossible or otherwise incoherent. I deal in particular with Ronald Dworkin’s famous exposition of the view. I argue that strong Anti-Archimedeanism constitutes an untenable philosophical stance, therefore making logical space for the (...) practice of a discipline such as metaethics—conceived as ethically neutral. This makes space, concurrently, for neutral conceptual jurisprudence. In the second part of the article, I attempt to show two things. On the one hand, that Dworkin’s widely discussed ‘challenge of disagreements’ to legal positivism is founded upon strong Anti-Archimedeanism. On the other hand, that having rejected strong Anti-Archimedeanism we should consequently reject the challenge as a serious challenge to positivism. This move, of course, does not thereby imply that accounting for legal disagreements is not an important jurisprudential task. But it marks—contra Dworkin—that there is no principled or a priori impossibility of doing so within a positivist framework. (shrink)

This paper addresses the relationship between law and coercive force. It defends, against Frederick Schauer's contrary claims, the following propositions: The force of law consists in three things, not one: the imposition of duties, the use of coercion, and the exercise of social power. These are different and distinct. Even if coercion is not part of the concept of law, coercion is connected to law many important ways, and these are amply recognized in contemporary analytic jurisprudence. We cannot determine how (...) important coercion is to the efficacy of law until we know what counts as coercive force. The question of what counts as coercion is not a matter for generalization or stipulation. It requires an explanation of the concept of coercion. (shrink)

This is my reply to five extended critical assessments of my book Law as a Leap of Faith, appearing together in a symposium issue of Law and Philosophy. The critics are Kevin Toh, Luís Duarte d’Almeida and James Edwards, Fábio Perin Shecaira, Cristina Redondo, and Matthew Smith. The topics include H.L.A. Hart’s philosophical legacy, the moral claims of law, the nature of legal reasoning, the doctrine of legal positivism, and the possibility of alienation from law.
