Social norms and the dynamics of practices.

I endorse five central themes of Charlotte Witt's Social Goodness: the pervasiveness and irreducibility of social roles and norms; normative externalism; the artisanal model; a richer social ontology; and the possible critical transformation of social norms from within. I reframe these themes within the biological account of the evolution and development of human ways of life in Joseph Rouse's Social Practices as Biological Niche Construction. Witt's social analysis attends to human bodies as loci of artisanal skills and social salience as gendered, sexed, and raced, but not to bodies as vulnerable, dependent organisms in social environments. A broader, biological conception of normativity shifts from Witt's focus on social roles and norms to the dynamics of social practices as shaping people's developmental environments. This more complex account of social dynamics enriches Witt's conservative account of how practices are transmitted and sustained. It thereby surpasses limitations in her account of how hierarchical social norms can be both obligating and open to critical challenge from within. It does so in three ways: by emphasizing normative conflicts within practices, by shifting from individual know-how to discursive practices as loci of artisanal authority, and by an account of power relations as intertwined with biosocial normativity.
