Abstract
In the framework of the current revival of Wittgenstein’s later philosophy as well as American pragmatism, social practices are seen as determining the conceptual content of our beliefs. This position amounts to an inferential semantics with inferential relations supervening on social norms and these norms, in turn, supervening on normative attitudes. The paper elaborates on the distinction between social practices and social behaviour. Three conceptions of social practices are considered: (1) social practices as being reducible to social behaviour; (2) social norms as constituting some sort of a link between physical and intentional states because the normative sphere has a wider scope than the conceptual sphere; and (3) the self-sufficiency of social practices in the sense that the normative and the conceptual sphere are identical and selfcontained. Key words: social practices, norms, beliefs, social behaviour..
