We may adapt a remark of St. Thomas Aquinas, and apply it to his own great work, the Summa Theologica: not everyone has talent to master this work; not everyone has a taste for the study it requires; not everyone has time to devote to such study. Aeterna Press

Combines selected philosophical passages from Thomas' "Summa Theologica" with detailed footnotes and explanations for modern readers.

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.

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.

This is the extended and annotated edition including * an extensive biographical annotation about the author and his life The Summa Theologiæ (Latin: Compendium of Theology or Theological Compendium; also subsequently called the Summa Theologica or simply the Summa, written 1265–1274) is the best-known work of Thomas Aquinas (c.1225–1274), and although unfinished, "one of the classics of the history of philosophy and one of the most influential works of Western literature." It is intended as a manual for beginners in theology and a compendium of all of the main theological teachings of the Church. It presents the reasoning for almost all points of Christian theology in the West. The Summa's topics follow a cycle: the existence of God; Creation, Man; Man's purpose; Christ; the Sacraments; and back to God. (courtesy of wikipedia.com). This is part 1, 'Prima Pars'. Aquinas's greatest work was the Summa, and it is the fullest presentation of his views. He worked on it from the time of Clement IV (after 1265) until the end of his life. When he died, he had reached Question 90 of Part III (on the subject of penance). What was lacking was added afterwards from the fourth book of his commentary on the Sentences of Peter Lombard as a supplementum, which is not found in manuscripts of the thirteenth and fourteenth centuries. The Summa was translated into Greek (apparently by Maximus Planudes around 1327), Armenian, many European languages, and Chinese. It consists of three parts. Part I treats of God, who is the "first cause, himself uncaused" (primum movens immobile) and as such existent only in act (actu) – that is, pure actuality without potentiality, and therefore without corporeality. His essence is actus purus et perfectus. This follows from the fivefold proof for the existence of God; namely, there must be a first mover, unmoved, a first cause in the chain of causes, an absolutely necessary being, an absolutely perfect being, and a rational designer. In this connection the thoughts of the unity, infinity, unchangeability, and goodness of the highest being are deduced.

The present work contains a critical edition, translation, and study of the "Summa perfectionis" of Pseudo-Geber, the most influential of the many texts of medieval alchemy. The study addresses such questions as the author's identity, his corpuscular theory of matter, the influence of the "Summa," and its own sources.
