Abstract
Retributivism is the notion that punishment is justified because, and only because, the wrongdoer deserves it. Proportionality is central to retributivism. A proportional punishment is one in which the severity of a punishment is proportional to the seriousness of the offense (for example, its wrongness or harmfulness). Michael Tonry’s collection is must reading for punishments theorists. The articles are well-chosen and the reflections of theorists such as Andreas von Hirsch, R. A. Duff, and Douglas Husak who have shaped punishment theory and who now consider the future of the principles that have governed their work, makes for interesting reading. The tie-in between retributivism and the practice of punishment is enlightening and sometime too often absent in the philosophical literature.
