Intuition oder Evolution?

Common morality is a central concept in both the medical ethics of Beauchamp and Childress as well as the Evolutionary Ethics advanced by Wilson and Richards. However, the latter merely describes the evolutionary origin of moral judgments but fails to establish why they are normative. The former on the other hand must claim that moral judgments are somehow objective in order to explain why they are normative. In contrast, the authors favour a model in which the coherence (Beauchamp & Childress), and thus the normative force of moral judgments is established through an intersubjective process of clarification and explication, albeit that such a process can never reach an end/Evolutionary Ethics).
