About the Book:The second edition of this accessible book features a new chapter on Nietzsche and an entirely new Part III that covers contemporary utilitarianism, rights-based ethical theories, contractarian ethics and virtue ethics, and recent debates between realism and anti-realism in ethics. The strengths of the first edition–its readability, historical approach, coverage of specific moral philosophers, and detailed recommended reading sections at the beginning of each chapter–combined with the new material make this an essential resource for all readers interested in ethics.
