Precedent decides legal cases, but few precedents make the case at bar _res judicata_. Instead, analogical reasoning is used, together with canons of statutory interpretation and theories of constitutional jurisprudence. The work under review provides a model and algorithm for analogical reasoning in the legal context. Technically, the paper represents very fine work, except that in order to find the ground of a rule, some human input is required. The rule is denied and consequences of the negation are automatically derived; (...) then, those which a person has previously marked as undesirable are candidates for the rule's ground. So this is a man-machine system, something not emphasized by the authors. Still, it is very fine work. Aside from its technical excellence and, on the other hand, an annoying number of missing articles, misplaced modifiers, and failures of agreement, the authors imply a certain understanding of law and how laws are made. The paper uses an ordinance rather than cases for analogical reasoning, after all, a practice that makes little sense unless the legislature is always perfectly consistent. Hence, the whole epistemological basis for the paper may be flawed. (shrink)

The paper deals with the possibility of a theory of the nature of law as such, a theory which will be necessarily true of all law. It explores the relations between explanations of concepts and of the things they are concepts of, the possibility that the law has essential properties, and the possibility that the law changes its nature over time, and that what is law at a given place and time depends on the culture and concepts of that place (...) and time. It also considers the possibility of understanding the institutions, such as the law, of cultures whose concepts are alien to us. The position advocated offers a reconciliation of ways in which a theory of the nature of law is parochial with its claim to be universal. (shrink)

Justice is a natural virtue. Well-functioning humans are just, as are well-ordered human societies. Roughly, this means that in a well-ordered society, just humans internalize the laws and social norms (the nomoi) - they internalize lawfulness as a disposition that guides the way they relate to other humans. In societies that are mostly well-ordered, with isolated zones of substantial dysfunction, the nomoi are limited to those norms that are not clearly inconsistent with the function of law - to create the (...) conditions for human flourishing. In a radically dysfunctional society, humans are thrown back on their own resources - doing the best they can in circumstances that may require great practical wisdom to avoid evil and achieve good. Justice is naturally good for humans - it is part and partial of human flourishing. All of these are natural ethical facts. "Natural Justice" develops these claims in four stages. Part I contextualizes the claim that justice is a natural virtue in relationship to Hume's famous argument about deriving ought from is, Moore's open-question argument, and the so-called fact-value distinction. The upshot of the discussion in Part I is the claim that there are no clearly decisive objections to existence of natural ethical facts. Part II traces the movement from neo-Aristotelian virtue ethics to virtue jurisprudence by articulating a theory of the judicial virtues. Among these are the virtues of practical wisdom and of justice. Practical wisdom or phronesis is best understood on the model of moral vision, which in the context of law is legal vision or situation sense. The virtue of justice is best understood as lawfulness. Just humans are law-abiding or nomimos - in that they internalize the widely shared and deeply held social norms of their social groups. This part concludes with the claim that a legally correct decision is the decision that characteristically would be rendered by a fully virtuous judge under the circumstances of the case. Part III argues that natural justice can be understood on the model of natural goodness as articulated in the work of Philippa Foot and Michael Thompson. The intuitive idea is that justice as lawfulness is naturally good for reason - using social creatures in human circumstances. This part also articulates and responds to a variety of objections. Part IV concludes by articulating the sense in which an aretaic theory of law that incorporates a natural virtue of justice as lawfulness can be viewed as an expression of the natural law tradition. The natural law idea that an unjust enactment is not a true law corresponds to two senses in which positive laws can fail to be nomoi (in the technical sense specified by virtue jurisprudence). First, a given enactment may contravene deeply held and widely shared social norms. Second, such enactments may be fundamentally inconsistent with the purpose of law - the promotion of human flourishing. (shrink)
