 Epstein (2008, 2014a) argues for modest pluralism about the ways social categories are set up. He introduces the term ‘anchoring’ to denote the setting up or putting in place of social categories or kinds. He proposes that all the theories discussed in  section 4  are theories of anchoring, but denies that social categories are all anchored in the same way. Instead, there are various “anchoring schemas”. He cautions that we sometimes classify kinds according to how they are anchored, but not in all cases.
