Leo J. Elders has extensive and impressive experience in teaching and researching the ethical thought of Thomas Aquinas.could help direct students to struggle more directly with what is probably the most complex and subtle treatment of the subject to be encountered anywhere.""- Philosophy in Review ""Elders brings to his study an almost encyclopedic knowledge of the history of philosophy. Although he advises his readers not to look for any novel interpretations of Thomas, the book is full of surprises. Time and again, he offers a concise history of the moral issue under consideration.A more authoritative introduction to the moral philosophy of Aquinas is not likely to be found. In fact, it is a delight to read.

""- Review of Metaphysics ""Elders unites the wealth of material into a reliable exposition of Aquinas's ethical thought that can serve as an excellent help to undergraduate students. Its detail and breadth of learning also make it valuable reading for graduate students. Father Elders has done a great favor in reminding us that a commentary on the moral section of the Summa Theologiae for those 'who restrict themselves to a purely philosophical approach' can indeed assist us in seeking 'the beauty of a life according to the virtues.'""- Thomist.
