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)

This article delineates some of the main issues that are debated by philosophers of law. It explores the connections between legal philosophy and other areas of philosophy, while also seeking to specify the distinctiveness of many of the concerns that have preoccupied philosophers of law. It illustrates its abstract points with examples focused on the separability of law and morality, the nature of the rule of law, the nature of rights, justifications for the imposition of punishment, and the identification of (...) basic legal entitlements.

Debates over the proper theory of, or approach to, constitutional interpretation rage through many Western constitutional democracies. Although the number of distinct theories, if finely individuated, might match the number of theorists who have entered the fray, it has become customary to group the competing accounts into two broad camps, commonly labeled ‘originalism’ and ‘non‐originalism’. This article presents an overview of non‐originalist approaches to constitutional interpretation. However, because non‐originalism is defined as the negation of originalism – that is, diverse theories (...) are grouped together as ‘non‐originalist,’ not so much by what they commonly affirm, as by what they commonly deny – the project naturally focuses as well on originalist theories of interpretation. After specifying what originalism maintains, and what objections it encounters, the essay sketches some of the more prominent non‐originalist approaches to constitutional interpretation and identifies some of the criticisms they face and worries they provoke. Preliminarily, it explains why ‘theories of constitutional interpretation’ constitute only a subset of ‘theories of judicial review.’. (shrink)
