Jean Porter : Moral Action and Christian Ethics

How do we decide whether an action is right or wrong? Recently, moral philosophers have moved away from the claim that we can find one definite solution to every moral problem by means of clearly established moral rules. While sympathetic to their critiques of modern moral theories, Porter questions whether these critiques go far enough in offering a positive alternative to a modern view of the moral act. Instead, she returns to Aquinas, and seeks to reclaim his understanding of the moral act as a product of interdependent moral virtues.
