Nowhere has H.L.A. Hart's influence on philosophical jurisprudence in the English-speaking world been greater than in the way its fundamental project and method are conceived by its practitioners. Disagreements abound, of course. Philosophers debate the extent to which jurisprudence can or should proceed without appeal to moral or other values. They disagree about which participant perspective—that of the judge, lawyer, citizen, or “bad man”—is primary and about what taking up the participant perspective commits the theorist to. However, virtually unchallenged is (...) the view that jurisprudence is fundamentally interpretive or “hermeneutic”; that it takes for its subject a certain kind of social practice, constituted by the behavior and understandings of its participants; that its task is to explain this practice and its relations to other important social practices; and that it can properly be explained only by taking full account of participant understandings. It is, perhaps, some measure of the hegemony of Hart's influence that Ronald Dworkin mounts his fundamental challenge to Hart's positivism squarely from within this jurisprudential orthodoxy. Dworkin may have exceeded the limits of the method as Hart conceived it, but, as Stephen Perry has argued, “the seeds of Dworkin's strong version of inter-pretivism were sown by Hart himself.”.

The essay discusses the import of the separability thesis both for legal positivism and for contemporary legal practice. First, the place of the separability thesis in legal positivism will be explored, distinguishing between “standard positivism” and “post‐Hartian positivism.” Then I will consider various kinds of relations between law and morality that are worthy of jurisprudential interest, and explore, from a positivist point of view, what kind of relations between law and morality must be rejected, what kind of such relations should (...) be taken into account, and what kind of such relations are indeed of no import at all. The upshot of this analysis consists in highlighting the distinction between two different dimensions of legal validity (formal validity and material validity respectively), and in pointing out that the positivist separability thesis can apply to formal validity only. On the other hand, when the ascertainment of material validity is at stake, some form of moral reasoning may well be involved (here and now, it is necessarily involved). The essay concludes with some brief remarks on the persisting importance of the positivist jurisprudential project. (shrink)

I argue that law is not best considered an essentially contested concept. After first explaining the notion of essential contestability and disaggregating the concept of law into several related concepts, I show that the most basic and general concept of law does not fit within the criteria generally offered for essential contestation. I then buttress this claim with the additional explanation that essential contestation is itself a framework for understanding complex concepts and therefore should only be applied when it is (...) useful to gain a greater understanding of uses of the concept to which it is applied (adducing criteria for making such judgments of usefulness). With that in mind, I then show that applying the appellation of essential contestation to the concept of law does not helpfully illuminate the most general concept of law (usually of most interest to legal philosophers) and therefore it should not be used, while allowing that it might be more useful for the related concept of the rule of law.
