Building on the strengths of the highly successful first edition, the Blackwell Guide to Ethical Theory has been thoroughly reorganized and revised, with the inclusion of an additional five new essays and major modification of nearly all of the remaining essays. Ranging from moral realism to virtue ethics, this superb volume presents a complete state-of-the-art survey of ethical theory. Written by an international team of leading moral philosophers, each of the 21 papers develops the main tenets, arguments, themes, and problems of the main normative and meta-ethical philosophical outlooks. Essays new to this edition cover evolution and ethics, capability ethics, virtues and consequences, and challenges facing virtue ethics. This volume is one of the most ambitious and authoritative surveys of ethical theory available today. It serves as a groundbreaking resource as well as a comprehensive guide for both students and scholars alike.
