Virtue ethics is perhaps the most important development within late twentieth-century moral philosophy. Rosalind Hursthouse, now presents a full exposition and defence of her neo-Aristotelian version of virtue ethics. She shows how virtue ethics can provide guidance for action, illuminate moral dilemmas, and bring out the moral significance of the emotions. Deliberately avoiding a combative stance, she finds less disagreement between Kantian and neo-Aristotelian approaches than is usual, and she offers the first account from a virtue ethics perspective of action 'from a sense of duty'. She considers the questions which character traits are virtues, and explores how answers to this question can be justified by appeal to facts about human nature.
