The Summa Theologica is a compendium of theology written by Thomas Aquinas between 1265 and 1273. In Roman Catholicism it is the sum of all known learning and doctrine, of all that can be known about God and humanity's relations with God -- a landmark in the history of theology that famously offers five proofs of God's existence, the first three of which are cosmological arguments; the fourth, a moral argument; and the fifth, a teleological argument. The third quarter of the thirteenth century marked the first decisive philosophical encounter between Hellenism and Christianity. The rediscovery of Aristotle's works after the Dark Ages ushered in a new era of intellectual fervor in Europe, and the work of Thomas Aquinas is a commentary on Aristotle, whose writings were lost to the non-Arabic world until the beginning of the Thirteenth Century. To many, Aristotle's worldview was a pagan threat to Christianity. To Aquinas, it provided an exciting cosmological framework on which to build an all-encompassing Christian worldview. His thoughts unfolding with a calmness of order and an assurance of judgment, Aquinas explores in the Summa the primary role of the senses in the acquisition of knowledge and the metaphysical analysis of things in terms of matter and form. But unlike Aristotle's "God," who did not care one whit about the world, the God of Christianity, insisted Aquinas, is a personal God. Like Aristotle, Aquinas believed that each human being has a soul and that all created things have a purpose. For Christians, all are part of a divine plan. This dazzling synthesis of Catholic doctrine has had a profound impact on Christian thinking since the thirteenth century and has become the de facto official teaching of the Catholic Church -- the intellectual underpinning of the Church to this day.

The only complete and unabridged copy of the Summa Theologica (or, Summa Theologiae) that appears in a single volume for a price that your pocket will love. The font is quite small so that you may own the entire work of the Summa, but it is none the less legible. Most other options appear in multiple volumes and exceed $100. If you want to own a print unabridged copy for a reasonable price, then this is your best choice.

The most important work of the towering intellectual of the Middle Ages, Thomas Aquinas's Summa Theologiae remains one of the great seminal works of philosophy and theology, while extending to subjects as diverse as law and government, sacraments and liturgy, and psychology and ethics.

This series offers central philosophical treatises of Aquinas in new, state-of-the-art translations distinguished by their accuracy and use of clear and non-technical modern vocabulary. Annotation and commentary accessible to undergraduates make the series an ideal vehicle for the study of Aquinas by readers approaching him from a variety of backgrounds and interests.

A shortened version of Kreeft's much larger Summa of the Summa, which in turn was a shortened version of the Summa Theologica. The reason for the double shortening is pretty obvious: the original runs some 4000 pages! (The Summa of the Summa was just over 500.) The Summa is certainly the greatest, most ambitious, most rational book of theology ever written. In it, there is also much philosophy, which is selected, excerpted, arranged, introduced, and explained in footnotes here by Kreeft, a popular Thomist teacher and writer. St. Thomas Aquinas is universally recognized as one of the greatest philosophers who ever lived. His writings combine the two fundamental ideals of philosophical writing: clarity and profundity. He is a master of metaphysics and technical terminology, yet so full of both theoretical and practical wisdom. He is the master of common sense. The Summa Theologica is timeless, but particularly important today because of his synthesis of faith and reason, revelation and philosophy, and the Biblical and the classical Greco-Roman heritages. This little book is designed for beginners, either for classroom use or individually. It contains the most famous and influential passages of St. Thomas' philosophy with copious aids to understanding them.

The Summa Contra Gentiles, one of Aquinas's best known works after the Summa Theologiae, is a philosophical and theological synthesis that examines what can be known of God both by reason and by divine revelation. A detailed expository account of and commentary on this famous work, Davies's book aims to help readers think about the value of the Summa Contra Gentiles (SCG) for themselves, relating the contents and teachings found in the SCG to those of other works and other thinkers both theological and philosophical. Following a scholarly account of Aquinas's life and his likely intentions in writing the SCG, the volume works systematically through all four books of the text.

Intended for advanced undergraduates, graduate students, and teachers, this new translation and exposition of the first two Questions of the Summa theologiae explains the text in unprecedented detail. The famous “Five Ways” of Aquinas receive ample consideration. The arguments are placed in their larger context in Thomistic philosophy and traced back to first principles, which in turn are illustrated by examples and defended from common objections. All technical terms occurring in the text are defined or explained in both the commentary and the glossary. Throughout, attention is paid to the rationale behind the order in which Aquinas proceeds. 574 pages; includes three appendices, an index of primary sources useful to know in reading the first two Questions, and exhaustive glossary. Michael Augros earned his Ph.D. in philosophy from Boston College in 1995. He has taught at Thomas Aquinas college for many years at its California campus, and now teaches at its New England campus. He is the author of two popular books on the philosophy of Aquinas, Who Designed the Designer? and The Immortal in You, both from Ignatius Press.
