Law contains many dualities, though most, if not all, of these dualities resolve into one complex puzzle: To what extent is law a matter of pure social facts, or moral value untethered to social facts? I argue that each concept of law reconciles this duality in a different way on the basis of certain beneficial consequences that might result. Instead of pitting concepts against one another universally, we should accept that the balance between law's social fact and moral value dimensions (...) is context-specific in relation to particular legal puzzles. This balance can be achieved only by considering both political theory and empirical data. (shrink)

Joseph Raz’s _Argument from Authority_ is one of the most famous defences of exclusive positivism in jurisprudence, the position that the existence and content of the law in a society is a wholly social fact, which can be established without the need to engage in moral analysis. According to Raz’s argument, legal systems are _de facto_ practical authorities that, like all _de facto_ authorities, must claim _legitimate_ authority, which itself entails that they must be _capable_ of being an authority. Further, (...) once we properly understand what constitutes practical authority, as captured by Raz’s _service conception_, we realise that the directives of any authority (including the law) must be wholly identifiable without recourse to moral analysis. While the argument has previously been criticised on the grounds that the law does not claim legitimate authority, and further that the service conception of authority itself is inadequate, we argue here that the argument is actually in a worse position than these concerns recognise, for it relies upon the mistaken principle that a sincere belief or claim that _p_ guarantees _p_’s conceptual possibility.

Joseph Raz's new book, Between Authority and Interpretation , collects his most important papers in the philosophy of law and the theory of practical rationality from the mid-1990s to the mid-2000s. In these papers, Raz not only advances earlier theses but also breaks new ground in a number of areas. I focus on three of Raz's topics here: theories of law, separability and necessity, and the normativity of law. While I am generally sympathetic to Raz's thinking on these topics, I (...) raise some room for doubt - especially with regard to his pessimism about finding a uniquely best theory of law and the relationship between law and morality.

Our concept of disorder is changing. This causes problems for projects of descriptive conceptual analysis. Conceptual change means that a criterion that was necessary for a condition to be a disorder at one time may cease to be necessary a relatively short time later. Nevertheless, some conceptually based claims will be fairly robust. In particular, the claim that no adequate account of disorder can appeal only to biological facts can be maintained for the foreseeable future. This is because our current (...) concept of disorder continues to be laden with ethical and political values in multiple ways. (shrink)

Legal philosophers divide over whether it is possible to analyze legal concepts without engaging in normative argument. The influential analysis of legal rights advanced by Jules Coleman and Jody Kraus some years ago serves as a useful case study to consider this issue because even some legal philosophers who are generally skeptical of the neutrality claims of conceptual analysts have concluded that Coleman and Kraus's analysis manages to maintain such neutrality. But that analysis does depend in subtle but important ways (...) on normative claims. Their argument assumes not only a positivist concept of law, but also that it counts in favor of an analysis of legal rights that it increases the number of options available to legal decisionmakers. Thus, whether Coleman and Kraus's analysis is right in the end depends on whether those normative assumptions are justified. If even their analysis, which makes the thinnest of conceptual claims, depends on normative premises, that fact serves as strong evidence of the difficulty of analyzing legal concepts while remaining agnostic on moral and political questions.
