Wanting the Common Good
Aquinas on General Justice

Ancient philosophers develop what has been called a compositional conception of justice. They treat the virtue of justice as conceptually anterior to a just social order and the moral standing of others. By reversing the order of priority, modern thought proposes structural conceptions of justice. However, Thomas Aquinas’s compositional account of justice may satisfy the demands of modern conceptions. He argues that there is a moral virtue called general or legal justice, which consists in responding to the demands of the common good and a society’s laws. The article reconstructs Aquinas’s account of general justice and argues that he manages to resolve certain difficulties inherent in a compositional conception of justice. He can explain how a shared conception of the common good is reached, and how those who hold rival conceptions can be accommodated and expected to promote it.
