Aquinas’ theology can be understood only if one comes to grips with his metaphysics of being. The relevance of this perspective is exhibited in his treatment of topics like creation, goodness, happiness, truth, freedom of the will, the unity of the human being, prayer and providence, God’s personhood, divine love, God and violence, God’s unknowablility, the Incarnation, the Trinity, God’s existence, theological language and even laughter. This book endeavors to treat these questions in a clear and convincing language. Is there a better method for improving one’s own theology than by grappling with the arguments of Thomas Aquinas?

Provides a sustained account of how the thought of Aquinas may be used in conjunction with contemporary science to deepen our understanding of divine action and address such issues as creation, providence, prayer, and miracles.

This book provides a fundamental introduction to Aquinas's theology of the One Creator God. Aimed at making that thought accessible to contemporary audiences, it gives a basic explanation of his theology while showing its compatibility with contemporary science and its relevance to current theological issues. Opening with a brief account of Aquinas’s life, it then describes the purpose and nature of the Summa Theologica and gives a short review of current varieties of Thomism. Without neglecting other works, it then focuses primarily on the discussion of the One God in the first part of the Summa Theologica. God's transcendence and immanence is a recurrent theme in that discussion. Evidence of God's immanent causality in the natural world grounds Aquinas's five arguments for the existence of God (the Five Ways) which then open onto God's transcendence. The subsequent discussion of the divine attributes builds on the modes of God's causality established in the Five Ways. It also shows the need for a language of analogy to preserve God's transcendence and prevent us from reducing God to the level of creatures, even as qualities such as "goodness" and "love," which we first know from creatures, are applied to God. The discussion of God's providence and governance establishes that the transcendent Creator God is most intimately present in creation. God acts in all creatures in a way that does not diminish their proper causality, but is rather its source. As there is no contradiction between God's transcendence and immanence, so there is no competition between the primary causality of God and the secondary causality of creatures. Empirical science, which is limited by its method to the secondary causality of creatures, is shown to be compatible with the broader discipline of theology which also embraces the primary causality of the Creator.

Gaven Kerr provides the first book-length study of St. Thomas Aquinas's much neglected proof for the existence of God in De Ente et Essentia Chapter 4. He offers a contemporary presentation, interpretation, and defense of this proof, beginning with an account of the metaphysical principles used by Aquinas and then describing how they are employed within the proof to establish the existence of God. Along the way, Kerr engages contemporary authors who have addressed Aquinas's or similar reasoning. The proof developed in the De Ente is, on Kerr's reading, independent of many of the other proofs in Aquinas's corpus and resistant to the traditional classificatory schemes of proofs of God. By applying a historical and hermeneutical awareness of the philosophical issues presented by Aquinas's thought and evaluating such philosophical issues with analytical precision, Kerr is able to move through the proof and evaluate what Aquinas is saying, and whether what he is saying is true. By means of an analysis of one of Aquinas's earliest proofs, Kerr highlights a foundational argument that is present throughout the much more commonly studied Thomistic writings, and brings it to bear within the context of analytical philosophy, showing its relevance to the contemporary reader.

A major new study of Aquinas and his central project: the understanding of human nature.

In A Comparative Analysis of Cicero and Aquinas, Charles P. Nemeth investigates how, despite their differences, these two figures may be the most compatible brothers in ideas ever conceived in the theory of natural law. Looking to find common threads that run between the philosophies of these two great thinkers of the Classical and Medieval periods, this book aims to determine whether or not there exists a common ground whereby ethical debates and dilemmas can be evaluated. Does comparison between Cicero and Aquinas offer a new pathway for moral measure, based on defined and developed principles? Do they deliver certain moral and ethical principles for human life to which each agree? Instead of a polemical diatribe, comparison between Cicero and Aquinas may edify a method of compromise and afford a more or less restrictive series of judgements about ethical quandaries.
