Principles may well be regarded as the main part of philosophy. They are among the major discoveries of philosophy, condensing in themselves much philosophical inquiry and insight. They are the starting point of much philosophical discussion. They are the base for exposition, for proof, and for criticism. They serve the student and the reader of philosophy much as legal maxims serve jurists and as proverbs serve the people. They are for scholastic philosophers the household truth of their tradition. This book includes not only all principles of scholastic philosophy but also exercises to apply the principles to several occasions. The book is useful for all students and professionals in philosophy.

The scholastic philosopher is interested in definition for a different reason than the lexicographer and linguist. The philosopher is trying to learn things. Fe defines, after investigating reality, in an attempt to describe reality clearly and to sum up some aspect of his understanding of reality. Hence, we find our scholastic philosophers adopting as a main feature of their method this insistence on defining, on precise and detailed explanation of their definitions, and on proving that their definitions da correctly express what a nature or activity is. A dictionary of the language of scholastic philosophy fitted to the needs of beginners and of undergraduate students of the subject is not available in English.

Scholastic Metaphysics: A Contemporary Introduction provides an overview of Scholastic approaches to causation, substance, essence, modality, identity, persistence, teleology, and other issues in fundamental metaphysics. The book interacts heavily with the literature on these issues in contemporary analytic metaphysics, so as to facilitate the analytic reader’s understanding of Scholastic ideas and the Scholastic reader’s understanding of contemporary analytic philosophy. The Aristotelian theory of actuality and potentiality provides the organizing theme, and the crucial dependence of Scholastic metaphysics on this theory is demonstrated. The book is written from a Thomistic point of view, but Scotist and Suarezian positions are treated as well where they diverge from the Thomistic position. Edward Feser is Associate Professor of Philosophy at Pasadena City College in Pasadena, California, USA. His most recent books include Aquinas and The Last Superstition: A Refutation of the New Atheism, and the edited volume Aristotle on Method and Metaphysics.

In So What’s New about Scholasticism? thirteen international scholars gauge the extraordinary impact of a religiously inspired conceptual framework in a modern society. The essays that are brought together in this volume reveal that Neo-Thomism became part of contingent social contexts and varying intellectual domains. Rather than an ecclesiastic project of like-minded believers, Neo-Thomism was put into place as a source of inspiration for various concepts of modernization and progress. This volume reconstructs how Neo-Thomism sought to resolve disparities, annul contradictions and reconcile incongruent, new developments. It asks the question why Neo-Thomist ideas and arguments were put into play and how they were transferred across various scientific disciplines and artistic media, growing into one of the most influential master-narratives of the twentieth century. Edward Baring, Dries Bosschaert, James Chappel, Adi Efal-Lautenschläger, Rajesh Heynickx, Sigrid Leyssen, Christopher Morrissey, Annette Mülberger, Jaume Navarro, Herman Paul, Karim Schelkens, Wim Weymans and John Carter Wood reconstruct a bewildering, yet decipherable thought-structure that has left a deep mark on twentieth century politics, philosophy, science and religion.
