Abstract

This chapter presents a new version of the theory of deliberative democracy, focusing on its specificity as a future genre, and based on arguments used to defend plausibility. Moral philosophy of ethical theories is applied in this context as a form of casuistics, involving probabilities, and not limited to case studies within the framework of applied ethics. The chapter then considers relationships between the sciences, scientific practices and ethics; the interweaving of facts and values; the quarrels that exist between coexisting disciplines; the competing approaches of epistemic pluralism, in both inter‐ and intra‐disciplinary forms; and argumentative coexistence in interdisciplinary contexts. It outlines the possible solution pathways, notably that of dialogical co‐argumentation. The chapter explores the question of pluralism of ethical theories with a focus on relevant elements that may modify an evaluation. In France, the precautionary principle has been enshrined in the Constitution since 2005, within the framework of the Environment Charter.
