This paper outlines an adverbial approach of value, which it proposes as an alternative to a "nominalistic" one. It starts from a review of a recent book of a French economist, André Orléan, who develops, from the instance of money, a theory of value which he thinks valid for all social values. The paper criticizes the main presuppositions of Orléan's model of value and tries to elaborate a more praxeological and a more social one.
