"Ralph McInerny knows as much about Thomas Aquinas, and about how to communicate his thought, as anyone else alive. He is not only a very learned commentator upon him, but also a fluent, lucid, and often entertaining writer, who can make profound ideas seem deceptively simple....McInerny offers an accessible guide to a difficult and important topic." The Heythrop Journal "McInery is perhaps the most important Catholic philosopher of his generation. While many limit philosophy to textual exegesis of formal logic, McInerny, in the spirit of his immediate predecessors Etienne Gilson and Jacques Maritain, still regards philosophy as the pursuit of wisdom, speculative and practical. Steeped in the history of philosophy, McInerny is a reliable guide to Aristotle and Aquinas and their commentators through the ages. He writes not for colleagues down the hall or for the appreciation of antiquity or who seek an intellectual compass in stormy times. Translated into many languages, his work rightly commands a global audience. For its freshness, Aquinas will only enhance McInerny’s status as a major interpreter of the Angelic Doctor." Jude P. Dougherty, The Catholic University of America "Aquinas lived in a time of remarkable intellectual and religious ferment. His thought, which McInerny following John Paul II describes as an implicit philosophy, articulates not just for his own time, but foe all times, the philosophical principles implicitly operative in human nature. In his new primer on Aquinas, Ralph McInerny manages the impossible. He gives us Aquinas, his times, the core of his philosophical teaching, and the significance of his continued contribution to philosophy and theology. With the deft stlye of the novelist and the clarity of a seasoned teacher of Aquinas, McInerny provides a marvelous path into the thought of the greatest of Catholic teachers."
