Punishment and Proportionality

This article concerns the problems of proportionality in the theory of punishment. The problem is how to determine whether the severity of a punishment for a criminal offense is proportional to the seriousness of that offense. The resolution to this problem proposed in the article is that, first, one understand punishment as pain or loss intentionally and openly inflicted on someone S in retaliation for something S did, by a person or agent who is at least as powerful as S, and, second, one take such retaliatory pain or loss as, within stable social groups, a means for preserving social order. Accordingly, it is argued that, on this proposal, the measure by which the severity of punishment is determined to be proportional to the seriousness of the crime for which it is inflicted is the minimal amount of pain or loss necessary to preserve social order. Sentencing policies that follow this measure, it is then observed, tend to yield less severe punishments than the policies that classical deterrence theory yields. Finally, the article offers an argument for regarding as morally more defensible sentencing policies whose goal is preserving social order than sentencing policies whose goal is that of classical deterrence theory, which is to achieve the smallest incidence of crimes consistent with not diminishing the overall welfare of society.
