Book excerpt: Prevent, Repent, Reform, Revenge is a study of the aims that people intend to achieve by the sanctions and treatments they recommend for wrongdoers. The book is designed to answer two main questions: What kind of analytical scheme can profitably reveal the nature of people's reasoning about the aims of sanctions they propose for perpetrators of crimes and misdeeds? In the aims that people express what changes in overt moral reasoning patterns appear between later childhood and the early adult years? The authors conducted interviews with 136 youths between the ages of 9 and 21 to find out what sanctions and aims they felt were appropriate in three cases of wrongdoing. The resulting information provides an important insight into adolescent moral development.
