“Margolis's book is a serious contribution to a new and valuable approach to moral philosophy. Rightly suspicious of approaches that attempt to ground morality in ultimate principles, Margolis seeks a way of understanding morality that heeds the data of the moral experience of individuals and groups of individuals. Focusing on intractable moral disputes, such as the Palestinian/Israeli conflict, Margolis provides a conceptual framework for a mode of moral reasoning that can move toward a modus vivendi, as opposed to a final moral judgment.”—J.
