Working on a theory of natural law derived largely though not exclusively from the work of Thomas Aquinas, Porter realized that Aquinas' theory of natural law is incomplete without the theory of virtue that accompanies it. The close connection between natural law and virtue is nowhere more evident than in Aquinas' account of justice, she says, which he claims is a virtue in the same robust way that temperance and courage are virtues. She discusses justice as a virtue, virtues and vices of the will, justice as a moral ideal, from ideal to law, and the perfection of the will.
