The method of reflective equilibrium (RE) is well known within the domain of moral philosophy, but hardly discussed as a method in professional ethics education. We argue that an interpersonal version of RE is very promising for professional ethics education. We offer several arguments to support this claim. The first group of arguments focus on a changed practice that is more team-oriented, inter-professional and aims at shared decision-making with patients and clients. The second group of arguments relate to the core aim of professional ethics education, namely to stimulate critical moral reflection. This central aim is a core professional moral competence that entails both a dialogical approach to practice and one's own moral beliefs as well as a more detached viewpoint on practice, reflection on types of cases and one's attitude as a professional in practice.
