With this study of Britten's music, centrally focused on his War Requiem, Martha C. Nussbaum has given readers a beautiful and many-sided book. It is simultaneously an insightful study of a great composer, an informed and sensitive interpretation of one of his masterpieces, and a deep philosophical reflection on attitudes to war. No previous book has demonstrated the philosophical significance and complexity of a body of musical works in so convincing a way. It is a model for future philosophical writing about music, and, in Nussbaum's dialogue with Britten's pacifism, an illuminating response to the horrors of war..
