Most contemporary moral philosophy is concerned with issues of rationality, universality, impartiality, and principle. By contrast Laurence Blum is concerned with the psychology of moral agency. The essays in this collection examine the moral import of emotion, motivation, judgment, perception, and group identifications, and explore how all these psychic capacities contribute to a morally good life. Blum takes up the challenge of Iris Murdoch to articulate a vision of moral excellence that provides a worthy aspiration for human beings. Drawing on accounts of non-Jewish rescuers of Jews during the Holocaust Blum argues that impartial principle can mislead us about the variety of forms of moral excellence.
