The Social Theory of Practices effectively criticized conceptions of social practices as rule-governed or regularity-exhibiting performances. Turners criticisms nevertheless overlook an alternative, "normative" conception of practices as constituted by the mutual accountability of their performances. Such a conception of practices also allows a more adequate understanding of normativity in terms of accountability to what is at issue and at stake in a practice. We can thereby understand linguistic practice and normative authority without having to posit stable meanings, rules, norms, or presuppositions underlying the manifest diversity of social life. Key Words: normativity practices rules language.
