In this interview, Luc Boltanski and Arnaud Esquerre introduce their book Enrichment and core concepts for the analysis of new developments in contemporary capitalism. The study focuses the analysis of the enrichment economy, which is grasped as a new form to explore and exploit ‘the past’ as a source for capitalist profits. The interview presents forms of valuation, which are more general principles of how value and prices can be ascribed to goods. The approach of Boltanski and Esquerre assumes an organized plurality of such forms of valuation. Also, the two sociologists stress the importance of discourses of valuation, which bring these forms of valuation into operation. As the interview makes evident, one major aim is to present a new perspective on the relationship between values, prices, and practices how prices are legitimatized or criticized on the basis of discourses of valuation. The interview situates Enrichment in the context of other contemporary sociological works, which focus on the economic core issue of value and valuation. The book can also be recognized as a proposal to reconcile structuralism and pragmatism in sociology. At the end of the interview, the more recent outcomes of the continuing collaborative work of Boltanski and Esquerre after Enrichment are discussed.
