This highly readable and engaging book deals, in a sophisticated and accessible manner, with a major point of contention in contemporary moral philosophy. Defending the import of moral principles, Maike Albertzart carefully comes to grips with the challenges posed by moral particularists. Students and advanced philosophers alike can profit from reflection on this book's arguments. Matthew Kramer, Churchill College, University of Cambridge, UK Moral Principles displays an uncommon but very welcome ability to bring a grounded moral understanding to bear on abstract questions in ethical theory. Albertzart provides much-needed structure and clarity to the increasingly unwieldy literature about the particularist challenge to the significance of moral principles. She articulates a promising conception of moral principles, one which sustains the pride of place of moral principles in ethical thought while at the same time capturing much of the appeal of particularism. This conception of principles is fruitful on its own as a contribution to meta-ethics, and it also has great potential to inform and illuminate work in normative ethics.
