Natural moral law stands at the center of Western ethics and jurisprudence and plays a leading role in interreligious dialogue. Although the greatest source of the classical natural law tradition is Thomas Aquinas's Treatise on Law, the Treatise is notoriously difficult, especially for nonspecialists. J. Budziszewski has made this formidable work luminous. This book - the first classically styled, line-by-line commentary on the Treatise in centuries - reaches out to philosophers, theologians, social scientists, students, and general readers alike. Budziszewski shows how the Treatise facilitates a dialogue between author and reader. Explaining and expanding upon the text in light of modern philosophical developments, he expounds this work of the great thinker not by diminishing his reasoning, but by amplifying it.

This close reading of Thomas Aquinas explores the relevance of the Divine Law to the modern world.

The second edition retains the selection of texts presented in the first edition but offers them in new translations by Richard J Regan -- including that of his Aquinas, Treatise on Law (Hackett, 2000). A revised Introduction and glossary, an updated select bibliography, and the inclusion of summarising headnotes for each of the units -- Conscience, Law, Justice, Property, War and Killing, Obedience and Rebellion, and Practical Wisdom and Statecraft -- further enhance its usefulness.

This monumental, line-by-line commentary makes Thomas Aquinas's classic Treatise on Happiness and Ultimate Purpose accessible to all readers. Budziszewski illuminates arguments that even specialists find challenging: What is happiness? Is it something that we have, feel, or do? Does it lie in such things as wealth, power, fame, having friends, or knowing God? Can it actually be attained? This book's luminous prose makes Aquinas's treatise transparent, bringing to light profound underlying issues concerning knowledge, meaning, human psychology, and even the nature of reality.

In his Treatise on the Virtues, Aquinas discusses the character and function of habit; the essence, subject, cause, and meaning of virtue; and the separate intellectual, moral, cardinal, and theological virtues. His work constitutes one of the most thorough and incisive accounts of virtue in the history of Christian philosophy. John Oesterle's accurate and elegant translation makes this enduring work readily accessible to the modern reader.

"This is the only free-standing English translation of the entire Treatise on human nature, which includes St. Thomas's account of the metaphysical status of the human soul and its relation to the human organism (Questions 75-77); the powers of the soul, especially the higher intellective powers that distinguish humans from other animals (Questions 78-89); and, those questions on human origins, the creation of the first man and first woman, and their status as being created in the image of God (Questions 90-102)."--Cover, p. 1.
