For UCLA Workshop. Please Don’t Cite Or Quote Without Permission. Grounding, Explanation, and Legal Positivism Samuele Chilovi & George Pavlakos 1. Introduction On recent prominent accounts, legal positivism and physicalism about the mind are viewed as making parallel claims about the metaphysical determinants or grounds of legal and mental facts respectively.1 On a first approximation, while physicalists claim that facts about consciousness, and mental phenomena more generally, are fully grounded in physical facts, positivists similarly maintain that facts about the content of the law (in a legal system, at a time) are fully grounded in descriptive social facts.2 Explanatory gap arguments have long played a central role in evaluating physicalist theories in the philosophy of mind, and as such have been widely discussed in the literature.3 Arguments of this kind typically move from a claim that an epistemic gap between physical and phenomenal facts implies a corresponding metaphysical gap, together with the claim that there is an epistemic gap between facts of these kinds, to the negation of physicalism. Such is the structure of, for instance, Chalmers’ (1996) conceivability argument, Levine’s (1983) intelligibility argument, and Jackson’s (1986) knowledge argument. Though less prominently than in the philosophy of mind, explanatory gap arguments have also played some role in legal philosophy. In this area, the most incisive and compelling use of an argument of this kind is constituted by Greenberg’s (2004, 2006a, 2006b) powerful attack on positivism.
