This paper addresses the responsibilities of philosophers. It distinguishes philosophers by profession, philosophers as a type of person playing a social role by doing philosophy, and philosophers without any professional or social role as a philosopher. It criticizes and rejects the internal goods view of philosophers’ responsibilities, according to which a philosopher’s only responsibility as a philosopher is to do ‘good’ philosophy. It examines the responsibilities of philosophy professors and the role of philosophy teaching in liberal education, criticizing the implications (...) of the internal goods view for university missions and commenting on related deficiencies of the Code of Conduct of the American Philosophical Association. The central conclusions are that philosophers should accept responsibilities to do philosophy in the public interest and to adopt a cross-disciplinary and collaborative stance toward their role in educating students in the forms of understanding and judgment that will best equip them for life and citizenship.
