This is the eighth in a series of posts on my own philosophical journey; the first post is here.
When we last saw them, Thomas and Aristotle had formed a seemingly unbeatable team, so much so that Thomism became known as “the perennial philosophy.” And yet somehow, after Descartes interest in Thomism faded, except within the Church. Philosophers didn’t have time for Thomas and Aristotle anymore. What happened?
You’ll often hear some variant of, “Newton proved Aristotle wrong about physics.” In other words, Aristotle was abandoned the same way science had abandoned belief in the four elements or the bodily humors. He was passé, old hat, been disproved, found wanting.
The truth is somewhat otherwise. So what really happened?
First, Thomism was associated with the Catholic Church. For some, that was sufficient reason to abandon our friends. But second, and more importantly, Thomism suffered from its own success. It had been the philosophy of Christendom for centuries. It had been worked on, and embroidered, and elaborated, and extended, and systematized, and rehashed until it was virtually impossible to come to grips with.
Thomism, I have said, is based on what we know of the world around us. And as such, for it to remain alive it must be possible to take new information into account, to see how it fits in, to adjust the whole. This is hard, and the larger the system is, the harder it is to do. As I understand it, the defenders of Thomism in Descartes’ day were not up to the challenge. They treated Thomism as settled doctrine, as near-holy writ, to be learned, and understood if possible, but not to be meddled with. They were ill-suited to the times.
And then, thirdly, the goals of philosophy had changed. In olden times, philosophers, natural historians, and the like gather information about the natural world for its own sake. Man, as a rational animal, desires to know; and it is fitting for us to learn as much as we can about the world God created, for he created it to be known. But with Descartes the emphasis changed. The goal was not simply mere understanding—the goal was mastery. The question was no longer, “What is the world like?”, but rather, “What can I make the world do for me?”
In short, the perennial philosophy was too Catholic, too hard, and too high-minded.
