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.

A study of Aquinas's theory of self-knowledge, situated within the mid-thirteenth-century debate and his own maturing thought on human nature.

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.

Natural moral law stands at the center of Western ethics and jurisprudence and plays a leading role in interreligious dialogue. Although the greatest source of the classical natural law tradition is Thomas Aquinas's Treatise on Law, the Treatise is notoriously difficult, especially for nonspecialists. J. Budziszewski has made this formidable work luminous. This book - the first classically styled, line-by-line commentary on the Treatise in centuries - reaches out to philosophers, theologians, social scientists, students, and general readers alike. Budziszewski shows how the Treatise facilitates a dialogue between author and reader. Explaining and expanding upon the text in light of modern philosophical developments, he expounds this work of the great thinker not by diminishing his reasoning, but by amplifying it.

This book explores the Christian theological, legal, constitutional, historical, and philosophical meanings of conscience for both scholarly and educated general audiences.

The Order of Things: The Realism of the Principle of Finality is an exploration of the metaphysical principle, “Every agent acts for an end.” In the first part, Fr. Garrigou-Lagrange sets forth the basics of the Aristotelian metaphysics of teleology, defending its place as a central point of metaphysics. After defending its per se nota character, he summarizes a number of main corollaries to the principle, primarily within the perspective established by traditional Thomistic accounts of metaphysics, doing so in a way that is pedagogically sensitive yet speculatively profound. In the second half of The Order of Things, Garrigou-Lagrange gathers together a number of articles which he had written, each having some connection with themes concerning teleology. Thematically, the texts consider the finality and teleology of the human intellect and will, along with the way that the principle of finality sheds light on certain problems associated with the distinction between faith and reason. Finally, the text ends with an important essay on the principle of the mutual interdependence of causes, causae ad invicem sunt causae, sed in diverso genere.
