“As we will see, Pope John Paul II, in his encyclical Fides et ratio strenuously upholds the tradition of giving priority to faith in the question of the relationship between faith and reason. To do otherwise, of course, would be to flirt with rationalism. Faith, however, must be understood; it is always, to borrow from St. Anselm, “seeking understanding,” What rational tools will one use to understand one’s Christian faith? Of the many philosophies that human culture knows and has known, which one ought to be chosen to aid in the comprehension of faith? Is every philosophy equal to this task?
As is well-known, St. Thomas chose the philosophy of Aristotle for this task. He found that Aristotle’s thought served the faith well; he found, most precisely, that the metaphysics of Aristotle provided a strong foundation upon with to “think the faith.” In light of this, and in light of Pope Leo XIII’s Thomistic revival, theologians began to ask if Catholic theology must be forever wedded to the philosophy of Aristotle. Many said no and attempted to change the philosophical foundations of Catholic theology – none with great success.
The University of Fribourg’s eminent philosopher, I.M. Bochenski, sets the stage for an answer as to why this was so. He explains that modern philosophy, that is, philosophy during the time between 1600 and 1900,
“came into being with the decline of scholastic philosophy. Characteristic of scholasticism is its pluralism (assuming the plurality of really different beings and levels of being), personalism (acknowledging the preeminent value of the human person), its organic conception of reality, as well as its theocentric attitude – God the Creator as its center of vision. Detailed logical analysis of individual problems is characteristic of scholastic method. Modern philosophy opposes every one of these tenets. Its fundamental principles are mechanism, which eliminates the conception of being as integral and hierarchical, and subjectivism, which diverts man from his previous concentration of God and substitutes the subject as the center. In point of method modern philosophy turned its back on formal logic. With some notable exceptions, it was characterized by the development of great systems and by the neglect of analysis.”
The mechanistic and subjectivist a prioris of modern philosophy, along with a whole set of reductionisms in contemporary philosophy, simply do not provide a solid enough grounding for Christian faith.”
