Abstract
Expert's independence is often highlighted in order to ensure the successful conduct of a scientific and technological evaluation. This chapter considers the attempt of the unusual science sociologist Bruno Latour to discover the functions to be summoned to form a new “parliament”, which will work as much on facts as on values to build a common world made of humans and non‐humans. His essay, involving the descriptive and normative dimensions of knowledge, is significant for the innovating participatory technology assessment (PTA) and emerging responsible research and innovation (RRI) experiences. With the famous philosopher and historian Thomas Kuhn, the chapter explores the crucial role played by epistemic values not only in choosing scientific theories, but also in producing scientific facts, as the philosopher Hilary Putnam defended. Finally, the chapter shows what would be the possible links between epistemic values and ethical values.
