This book is a systematic and constructive treatment of a number of traditional issues at the foundations of ethics. These issues concern the objectivity of ethics, the possibility and nature of moral knowledge, the relationship between the moral point of view and a scientific or naturalist world-view, the nature of moral value and obligation, and the role of morality in a person's rational lifeplan. In striking contrast to traditional and more recent work in the field, David Brink offers an integrated defense of the objectivity of ethics.
