This paper recalls the motivation for a normative account of the conceptual content of our beliefs, namely the problem of rule-following. It employs Brandom's social, inferential semantics as a paradigmatic example of such an account of conceptual content. The conceptual content of our beliefs - and the meaning of the sentences that we use - is normative in the sense that it is determined by social, normative practices. Nevertheless, a description of content and meaning is possible. The paper argues that the purpose of a normative account of conceptual content is a rational reconstruction in the sense of a conceptual analysis.
