Garth L. Hallett provides the first thorough, systematic exposition and defense of proportionalism in Christian ethics. Prominent in both philosophical and theological ethics, proportionalism judges the morality of acts by their proportion of good and evil.
Hallett proposes judging acts using a norm he calls Value Maximization. He defines this norm and offers a full response to such critics of all forms of proportionalism as Finnis and Grisez. The author assesses the norm's moral and theological validity in and of itself; in dialogue with the encyclical Veritatis Splendor; and in comparison with various rival viewpoints, stressing natural law, divine commands, respect for persons, inviolable goods, proportionate ends, irreducible rights, and agent-centered ethics. He appraises the norm's overall significance, showing its rootedness in Christian tradition, its inclusiveness and amplitude, and its relevance to those seeking a foundation for Christian ethical thought and moral activity.
