Abstract

The punishment of criminals is a topic of long-standing philosophical interest since the ancient Greeks. This interest has focused on several considerations, including the justification of punishment, who should be permitted to punish, and how we might best set punishments for crimes. This entry focuses on the most important contributions in this field. The focus will be on specific theoretical approaches to punishment including both traditional theories of punishment (retributivism, deterrence, rehabilitation) and more contemporary alternatives (expressivism, restorative justice, hybrid theories, unified theories) with an additional section on capital punishment, perhaps the particular form of punishment that has received the most sustained philosophical attention. These theories of punishment address two important questions: first, who should be permitted to punish and, secondly, who should be permitted to be punished. These questions then concern the justification of punishment and its distribution. While the majority today often identifies their theories as retributivist, there is a great diversity of theories defended. This entry will highlight the leading work for each view.
