In this fresh look at our justifications for punishment, Walker argues that the modern retributive theory of punishment has not solved the problems of the classical utilitarian approach, and has indeed created new ones of its own. Having researched these problems and discussed them with judges, magistrates, jurists, philosophers, and prisoners, he distinguishes rhetoric from hard reasoning and shows that attempts at intellectual compromises between utilitarians and retributivists do not stand up to close examination. The book also deals with aspects normally left to theologians, such as remorse and forgiveness, and with the humanitarian movement.
