 Many constructionist projects concerning human kinds are, or are pursued as part of, normative projects. Thinkers interested in gender, race, mental illness and disability, are often motivated not only by concern with the metaphysics of these categories, but with questions of social morality and justice that connect with them. For instance, Sally Haslanger’s work on the construction of gender and race (Haslanger 2012), or Elizabeth Barnes’s (2016) constructionist account of disability seem to essentially incorporate normative concepts. This connection, in turn, raises a number of further questions about why they are connected, and how we ought to understand their relationship.
