Abstract

The interdisciplinary aspect of collective deliberation, involved in participatory technology assessment (PTA) and responsible research and innovation (RRI), raises issues in relation to the cohabitation of disciplines. In ethics, the choice of which path to take is rarely clear or simple. Without falling into relativism, descriptions of the same actions may vary. Faced with the hard and apparently inevitable reality of misunderstandings, loyalties, interests and requirements, which are mutually incompatible, ethics offers one way of delimiting a conflict in order to maintain relationships. This chapter considers the difficulties involved in judgment, the fact of pluralism, the ethical pluralism of values, ethical theories and their place in practical reasoning between monism and relativism, and finally the potential and the limitations of deliberative democracy. Reaching an ethical judgment on a question, or simply reaching judgment on a question, is a difficult task for any individual.
