Abstract
This chapter talks about ethical deliberations that may be individual, potentially based on thought experiences or overhanging and discusses a real confrontation of evaluations and the deliberations of other individuals. This is one of the new elements introduced by participatory technology assessment (PTA), particularly in Europe. Stakeholder participation has been promoted by European agencies as a pillar of responsible research and innovation (RRI), confirming the need to consider the risks of exposure to the deliberations of others. The chapter describes the resources offered by certain political philosophers who considered proposing the best possible systems for managing pluralism. It discusses the criteria of one of the most promising political theories: deliberative democracy. The qualification of this theory will prove useful in managing the cohabitation of individual and collective evaluation. The chapter considers a number of possible improvements to this theory, notably with regard to one of its major components: ethical arguments.
