 In addition to pluralism about anchoring schemas, he also argues that anchors are heterogeneous (Epstein 2015): even for a single anchoring schema, the anchors that feed into that schema—i.e., the facts that metaphysically set up a social category—are often diverse. Legal categories in the U.S., for instance, are anchored by facts such as jury instructions, trial results, legislative enactments, judicial interpretation, and environmental regularities. Even theories of practice, he argues, do not have the resources to accommodate this heterogeneity.
