and content. These changes reflect advances in the bioethics literature over the past five years. The most dramatic expansions of the text are in the comprehensiveness with which the authors treat different currents in ethical theory and the greater breadth and depth of their discussion of public policy and public health issues. In every chapter, readers will find new material and refinements of old discussions. This is evident in the many new sections on topics like communitarianism, ethics of care, relationship-based accounts, casuistry, case-based reasoning, principle-based common-morality theories, the justification of assistance in dying, rationing through priorities in the health care budget, and virtues in professional roles. The most extensive revisions are in chapters 1, 2 and 8.
