Legal Positivism and the Real Definition of Law

We explore an underappreciated tension at the heart of the debate over legal positivism. On the one hand, many legal philosophers aspire for the debate to tell us what law is, and the nature of law. But on the other hand, the positions in the debate are generally formulated such that they’re about something else: what law is necessarily connected to or dependent on. This is a genuine tension, because theses about what law is necessarily connected to or dependent on do not by themselves state or automatically settle what law is or the nature of law. This tension prompts us to propose a new approach to formulating positivism and antipositivism as theses about the real definition of law. Our proposal is simple, but fruitful. We argue that it better insulates and unifies the debate: that is, it prevents orthogonal theses from trivially vindicating or falsifying positivism and antipositivism, and it explains how different threads of the existing debate contribute to a single topic. We close by briefly considering two recent arguments about exclusive positivism, to illustrate how our discussion bears on contemporary jurisprudential debates.
