Thomas Aquinas

The topics of Questions i-iv of St. Thomas Aquinas' Commentary on the De Trinitate of Boethius are of vital interest to the Christian philosopher and theologian. Written while Aquinas was a youthful Master of Theology, the Questions show his solidarity with Christian tradition, his wide acquaintance with Scripture and the Fathers of the Church, and his creative use of philosophy in addressing theological issues. Question i treats of the possibility of our knowing God, and the human limitations of this knowledge. Question ii concerns theology as a science which reaches out to God by faith in his revealed word and uses philosophical reasoning to throw light on the contents of revelation. In Question iii Aquinas takes up the nature of faith, showing its relation to religion and its necessity for the welfare of the human race. He argues for the catholicity or universality of the Christian faith and defends the orthodox teaching of the trinity of Persons in the one God. Question iv turns to a set of philosophical problems occasioned by Boethius' treatise on the Trinity: the factors that cause a plurality in genera, species and individuals. In this connection Aquinas makes one of his most controversial statements of the principle of individuation.

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.

The Treatise on Happiness and the accompanying Treatise on Human Acts comprise the first twenty-one questions of I-II of the Summa Theologiae. From his careful consideration of what true happiness is, to his comprehensive discussion of how it can be attained, St. Thomas Aquinas offers a challenging and classic statement of the goals of human life, both ultimate and proximate. This translation presents in accurate, consistent, contemporary English the great Christian thinker's enduring contributions on the subject of man's happiness.

Book Two of the Summa Contra Gentiles series examines God's freedom in creation, his power as creator of all things, and the nature of man, particularly the unity of soul and body within man. The Summa Contra Gentiles is not merely the only complete summary of Christian doctrine that St. Thomas has written, but also a creative and even revolutionary work of Christian apologetics composed at the precise moment when Christian thought needed to be intellectually creative in order to master and assimilate the intelligence and wisdom of the Greeks and the Arabs. In the Summa Aquinas works to save and purify the thought of the Greeks and the Arabs in the higher light of Christian Revelation, confident that all that had been rational in the ancient philosophers and their followers would become more rational within Christianity. Book 1 of the Summa deals with God; Book 3, Providence; and Book 4, Salvation.
