This monograph, The Knowledge of the First Principles in St. Thomas Aquinas, has a well-articulated vision of the issue addressed, both from the metaphysical and epistemological perspectives. It surveys the nature, roles, and habits of basic principles from the Thomistic view. It is a study directed towards a wise understanding of basic reality.

An in-depth study of Aquinas’s doctrine of the actus essendi.

If there is any one author in the history of moral thought who has come to be associated with the idea of natural law, it is Saint Thomas Aquinas. Many things have been written about Aquinas's natural law teaching, and from many different perspectives. The aim of this book is to help see it from his own perspective. That is why the focus is metaphysical. Aquinas's whole moral doctrine is laden with metaphysics, and his natural law teaching especially so, because it is all about first principles. The book centers on how Aquinas thinks the first principles of practical reason, which for him are what make up natural law, function as laws. It is a controversial question, and the book engages a variety of readers of Aquinas, including Francisco Suarez, Jacques Maritain, prominent analytical philosophers, Straussians, and the initiators of the New Natural Law theory. Among the issues addressed are the relation between natural law and natural inclination, how far natural law depends on knowledge of human nature, what its obligatory force consists in, and, above all, how it is related to what for Aquinas is the first principle of all being, the divine will.

Metaphysics, formerly the queen of science, fell into oblivion under the onslaught of empiricism and positivism and its very possibllity came to be denied. Professor Elders traces the history of this process and shows how St. Thomas innovated in determining both the subject of metaphysics and the manner in which one enters this science, particularly in the framework of his Aristotle commentaries. The work then considers being and its properties, its divisions into being in act and being in potency, into the act of being essence, and into substance and the accidents. Finally the causes of being are considered. The work also introduces and surveys the extensive literature of Thomas interpretation of the past 50 years.

Metaphysics now joins the series of translations of Father Gardeil's Initiation a la Philosophie de S. Thomas d'Aquin. After an Introduction which discusses the general notion of metaphysics as a science, the relation of metaphysics to the critical analysis of knowledge and metaphysics as developed by Aristotle and St. Thomas, the author turns to the questions of First Philosophy which have concerned philosophers from Parmenides to Sartre and Heidegger. In seven chapters he considers being in itself and as it is known, the transcendental, the categories of being, act and potency, essence and existence and causality. As in the other volumes of this series, the author includes a generous selection of texts from the works of St. Thomas carefully correlated with the various chapters of the work itself. These are not mere snippets, but substantial quotations drawn from the Commentary on Aristotle's Metaphysics, De ente et existentia, the Disputed Questions and the two Summas. The reader has the words of Aquinas in the best modern English versions before him. Here is St. Thomas for the thinker--unfiltered. A most valuable addition in this fourth volume is the technical vocabulary of Thomistic and scholastic terms, covering all four volumes of the Initiation. The beginner in metaphysics will find this book most valuable, for it presents clearly the basic problematics and the Thomistic solution of them. For the more profound student here is a clear, concise (but not cursory) review of the science. Thomistic metaphysics, in Father Gardeil's presentation, is not an historical curiosity but a living and lively discipline. While the aim of the work is to give a synthetic view of St. Thomas' thought, the insights of modern or contemporary philosophers is not neglected. The translator's notes offer clarification and add bibliographical information on works published since the French edition. Valuable as a class manual, indispensable as supplementary reading, this book can serve the needs of a strictly philosophical course or one designed as a preparation for theology.
