This chapter introduces the ethical puzzle that this book is about: people who make excellent contributions to the arts, science, intellectual life, politics, sports, and so on can also behave immorally. A person’s excellent contributions are grounds for honour and admiration, but their immorality is grounds for blame. How, then, should people respond to such admirable yet immoral people? Instances of these cases drawn from the arts, science, intellectual life, politics, and sports are given. The structure and aims of the book are outlined.
