 How is it that naturalism can play a role in motivating Legal Positivism? As has often been remarked, the core Positivist claim about the relationship between law and social facts amounts in effect to a claim that law is reducible to social facts, which—given that “social facts” here is, tacitly if not expressly, limited to psychological and sociological facts—further amounts to the claim that law is reducible to naturalistic facts. It should be clear enough why this would be appealing to people with S-naturalist commitments, for it would, so to speak, mean that we can “place” law in the realm of naturalistic facts and entities. (By analogy, consider why S-naturalists would be drawn to the idea that the existence and contents of human minds depends solely on facts about human brains.) Unsurprisingly, therefore, the affinities between Legal Positivism and S-naturalism have not gone unnoticed. (See Kar 2006, p. 931; Leiter 2018, pp. 19–20.)
