Moral validity and moral motivation : critical notes on Nunner-Winkler’s ethics of voluntary self-commitment

Abstract

For many years Gertrud Nunner-Winkler has been occupied with empirical research on the complex subject-matter of moral development, motivation and knowledge. Although so-called descriptive ethics is rather looked down upon by professional ethicists, Nunner-Winkler’s works demonstrate that one can learn a great deal from experience.
