 But even local constructionist claims can be interesting to the extent that they try to show some object may be produced by unacknowledged social practices—when they are covert constructions. This is the role that they play in the philosophy of psychiatry (Hacking 1995a, Scheff 1984, Showalter 1996, cf. Murphy 2006), the philosophy of the emotions (Averill 1980a, 1980b, Armon-Jones 1986, Harré 1986, cf. Griffiths 1997), the philosophy of race (e.g. Outlaw 1990, 1995; Mills 1998; Taylor 2013), and the philosophy of gender (see  Feminist Theories of Sex and Gender: Gender as Socially Constructed).  Here the local claim that some kind (for example mental illness, emotion, race, or gender) is explained by received culture or practice retains its interest because it offers a metaphysical alternative to other explanations (biological, religious, etc.) of the differential features of the kind members as well as an alternative to skepticism about the reality of the  kind.[6]
