Goodness and Rightness in Thomas Aquinas's Summa Theologiae
"This clear and cogently argued work will engage not only theologians and medievalists, but moral philosophers as well.... Keenan's careful analysis of the texts, coupled with his obvious mastery of the contemporary discussion, make this a particularly valuable work." --Joan Franks, OP, Fordham University"[The author] shows a sure mastery of both contemporary moral theology and of the sources of the Catholic Tradition. He should be one of those who shape the next generation of American Catholic moral theology." --John P. Langan, SJ, Georgetown University
