 Of course, this argument for Replacement Naturalism only seems to work against “formalist” theories of adjudication that are committed to the rational determinacy of law. But, some object, “No contemporary analytic jurisprudent is a formalist” (Coleman 1998, p. 284), and some have even claimed that the “formalists” the Legal Realists opposed were not committed to the rational determinacy of law (Paulson 2001, p. 78). Both objections seem mistaken: Ronald Dworkin, for example, is committed to the rational determinacy of law in exactly the sense at issue for the Replacement argument. The targets of the Legal Realist critique were, equally, committed to the rational determinacy of law (Etchemendy 2021); indeed, it would be impossible to make sense of what the Realists were doing if that were not so. The Replacement Naturalist might take the view that there is no reason to call for “naturalizing” theory of adjudication in the range of cases where legal reasons are satisfactory predictors of legal outcomes (i.e., precisely those cases where the foundationalist program can be carried out). One may worry, again, about whether there is an interesting or fruitful normative story to be told (rather than a merely banal descriptive sociology), but it suffices for the analogy with Quine that there remains some substantial domain of cases where the foundationalist program cannot be carried out, so that the case for replacement remains intact.
