The author of this paper looks back on more than three decades of experience in teaching ethics at business schools and universities as well as in teaching and implementing them in business enterprises. Even in his academic career as a physicist, philosopher, and educator, he worked out the implications for ethics in a chapter of his doctoral thesis on the philosophical consequences of quantum physics. During his entry into the business world at IBM, he gained his first experience regarding the importance of ethical behavior for business success. He seized the opportunity to take an in-depth look at the possibilities and limits of implementing ethics and thus also at the individual and social well-being in a large company after his employment with the Gerling Insurance Group, at that time the largest industrial insurer in Germany with an international orientation. Together with the third-generation owner, he initiated an “Academy for Risk Research” there in order to implement an ethics-based risk culture in the company. For 16 years, he successfully helped to shape the corporate culture, also with the involvement of a corporate university for whose contents he was responsible. After the company was sold, he returned to university teaching and research. The rare combination of practical experience and transdisciplinary knowledge enabled him to develop and successfully implement a new didactic approach to teaching applied business ethics. Both collective and individual well-being prove to be a consequence of ethical behavior.
