 Retributivism presents no special puzzles about who is the desert subject: the wrongdoer. What may be particularly problematic for retributivism is the claim that certain kinds of persons (children or the insane) or entities (states or corporations) can or cannot deserve punishment. The fundamental issues are twofold: First, can the subject be responsible for wrongdoing? Second, does the subject have the mental (or information processing) ability to appreciate the punishment as conveying condemnation for a wrong done, rather than seeing it simply as hard treatment? Small children, animals, and the insane may lack both abilities, but a person who is only temporarily insane might lack one ability but not the other. (For contrasting views about punishing artificial persons, such as states or corporations, see French 1979; Narveson 2002.)
