In this book, Andrea Clausen intends to reconcile Kripke's point according to which conceptual content has to be considered as being constituted by social, normative practice - by a process of mutual assessments - with the view that the content of empirical assertions has to be conceived as objective. She criticizes approaches that explicate content-constitutive practice in non-normative terms, namely in terms of sanctioning behavior (Haugeland, Pettit, Esfeld). She also rejects a pragmatist reading of Heidegger that proceeds from thoroughly normative but pre-conceptual practice. She develops and defends a particular reading of an approach that conceives normative, conceptually articulated practice - giving and asking for reasons - as primitive (Brandom, McDowell).
