At the dawn of the 20th Century, several writers who were to become famous under the title of "Modernists" were advancing a deep agenda for reform in the faith and praxis of the Roman Catholic Church. But their agenda met with serious and scholarly opposition from another group of writers, whose essays are here made available in English. They include the historian and university rector Pierre Battifol, the biblical exegete M.J. Lagrange, OP, the Jesuit historical theologians Eugène Portalié and Léonce de Grandmaison, and the philosophers Eugène Franon and Joannès Wehrlé. All welcomed the historico-critical methods of research, and far from thinking them fatal to orthodoxy (as the Modernists did), they thought the Church's faith would survive and be strengthened by rigorous scholarship. These thinkers, then, are the true predecessors of Pius XII (Divino afflante Spiritu) and Vatican II (Dei Verbum). At the same time, these men thought outside the boxes drawn by 19th Century Positivism (Loisy), anti-intellectualist pragmatism (LeRoy), and romantic mysticism (Tyrrell). Their concerns hold new significance in the light of John Paul II's 1990 encyclical Fides et Ratio. Reading these too-long forgotten writers, then, deepens in a new way one's understanding of the Catholic Church's decision to decline and even condemn the Modernists' agenda, whether one ultimately applauds that decision or deplores it.

“Pre-modern philosophy” means the line of reflection that started with Plato andvAristotle, passed through Augustine and Boethius, and reached its acme in Aquinas, Scotus, and Suarez. The whole line was harshly judged by Descartes, then mocked by the empiricsts of the 18th Century. Why, then, did Pope Leo XII make a determined effort to revive it? And, more importantly, why was the revival a stunning success by the middle of the 20th Century?

The answers to both questions are found in a famous German book, Philosophie der Vorzeit by Josef Kleutgen, now available for the first time in English. Pre-ModernPhilosophy Defended shaped and strengthened Pope Leo’s resolve. It showed how inaccurate the harsh judgments had been and how sadly inferior the modern replacements from Descartes to Hegel had turned out to be in many respects.

Not in all. Kleutgen was no knee-jerk reactionary. He made no bones about the obsolete status of pre-Newtonian physics and cosmology. Rather, he focused on the central boast of “modern” thought, namely, that it had turned at least to the “subject” and had provided a long-needed thing called a “critique of knowledge.”

This book is must reading for intellectual historians and for philosophers working today in epistemology. But most of all, it is essential reading for laity and clergy concerned about revivals of modernism in the church. What was modernism, after all, but an attempt to make the Church revise her theology in the “light” of Kant or Hegel? This is why every Modernist knew Kleutgen’s name and hated this book.

Here is the first English translation (from the German) of the master work of Josef Kleutgen, the nineteenth century social philosopher whose thought lies at, or near, the heart of Catholic Social Thought. Kleutgen is widely and rightly seen as the shadow author of the social encyclicals of Leo XII. Leo’s Rerum Novarum remains the origin and constant reference point of all Catholic Social Teaching. And Popes since have dated their own social encyclicals from Rerum Novarum – hence, Quadragesimo anno and Centesimus annus. —Gerard V. Bradley, University of Notre Dame

Pre-Modern Philosophy Defended is must reading for intellectual historians and for philosophers working today in epistemology. And it is essential reading for laity and clergy concerned about revivals of modernism in the church. What was modernism, after all, but an attempt to make the Church revise her theology in the ‘light’ of Kant or Hegel? This is why every Modernist knew Kleutgen's name and hated Philosophie der Vorzeit (Pre-Modern Philosophy Defended).

When Leo XII promulgated Aeterni Patris in 1879, he stipulated that the “Leonine,” or official, edition of the Summa should always be printed in conjunction with Cajetan’s Commentary. For five hundred years they were studied together. Generations were trained by reading through the Summa article by article with Cajetan’s commentaries in hand. Early printed editions of the Summa typically included them in a Talmudic arrangement, as marginal text running around each article by Aquinas. This edition imitates that example. Recently, serious thinkers of all denominations – and none – have found new reasons to be interested in St. Thomas. His text is deceptively simple, yet important issues are handled in every article, sometimes below the surface. Cajetan extracts these hidden issues, and explains and elaborates on them with remarkable affinity to modern analytical philosophy. Part of that affinity lies in the use of modal logic, a tool whose importance was overlooked between the Renaissance and the twentieth century. The time is ripe for an analytically-inspired translation of Thomas: hence this volume. Never until now has Cajetan’s Commentary been put into English in its entirety. William Marshner’s translation is consistent with fidelity to the technical force of the original. The translator’s footnotes acknowledge what empirical science has made obsolete in the work of St. Thomas, and also make clear how much today’s science would have saved Thomas useless labor. This volume will, for the first time, make Cajetan’s help available to the modern reader.
