 Dworkin’s theory of adjudication (Dworkin 1986) makes a popular target for the Normative Naturalist. Dworkin’s theory says, very roughly, that a judge should decide a case in such a way that it coheres with the principle that explains some significant portion of the prior institutional history and provides the best justification for that history as a matter of political morality. Can a Normative Naturalist be a Dworkinian?
