Walter Farrell's series of four books explaining the concepts contained in St. Thomas' "Summa Theologica" is as ambitious as the Summa itself, as it takes the metaphysical reasoning of Aquinas and presents it in 20th Century language for better accessibility to more modern audiences. My own copy of the Summa is two volumes, but they are massive, with double-columned pages of text in very small print. It took me two months just to get through half of the first volume, and that was years ago. So the Companion seems like a reasonable condensation. However, I may have to go back and reread some of the actual Summa with regard to the subjects covered in this section of the Companion.
The second volume of the Companion regards human happiness, a worthwhile discussion for anyone of any faith. Yet Farrell goes a little overboard with his modern analogies here. Normally, when a teacher can apply ideas that are centuries old to contemporary problems, this really helps to drive home the timeless work of the original author. Not always so here. Volume 2 reads like a series of loose associations weakly tied to the original outline of logic spelled out by Thomas Aquinas. Often, it seemed the thread of the Summa was forgotten all together. Therefore, it reads more like a series of Farrell's own preachings from the pulpit. When he does get back to Aquinas, it feels like he is trying either too hard to relate the Summa to everyday experience.
"One goat may butt into another, looking very much like one football player butting into another; but the acts are quite different, for one is human, the other is the act of a goat. One was placed in view of the end; the other was not. One has a moral object, while the other has not."
What?! Passages like this don't serve to illustrate anything. Two linebackers clashing on the 20-yard line have a moral object? I guess the point was that behaviors can look the same but have very different objectives. But it is not clear, and the point of these "Companions" to the Summa was to clarify. Instead, Farrell seems to frequently derail.
I am not saying this is a bad book at all. In fact, it is infinitely highlightable and full of practical wisdom. It also does a fantastic job explaining the moral, theological, and intellectual virtues, as well as the complex systems in which these virtues interact throughout a person's life. And just as we are prepared for movement of reason by the virtues, we are prepared for the movement of God by the gifts of the Holy Spirit, the person of the Trinity by which most who study Christian theology are both fascinated and baffled. Here, Farrell gives a passionate explanation of what the Holy Spirit does in the lives of human beings.
But the main point of the book is that our actions are what provide us with happiness, that in the moral realm quantity is measured by degrees of perfection, and that good habits in the practice of the virtues take away much of the redundancies and inefficient effort to reach that perfection. This reminds me of a person in addiction recovery. The more they practice recovery, the more they practice healthy habits, interpersonal effectiveness, and temperance, the easier it is to stay sober. In fact, the more success one finds in their practice, the harder it is to go back to older bad habits. Conversely, unhealthy habits are hard to break. If you spend all your time reading celebrity gossip or watching brainless TV, you don't make room for things that will help you grow. Garbage in, garbage out. The ultimate lofty goal of human action is the ultimate perfection, namely God, and thus the ultimate source of happiness is God.
Perhaps one of the more interesting elements of the book came toward the end, when discussing Law, but I didn't feel I gained any insights from the promising discussion. I had a hard time parsing out if Farrell was advocating for no division between church and state, though I think his point was that the best governmental laws are those that support the law of nations, which is a kind of global human law based on reason and the common good. However, he does not address the conflict we have today where people create laws believing they are for the common good that appear to go against the law of nations. For example, one group feels justified in censuring speech deemed harmful because it is misinformation, but so much of what is labeled misinformation turns out later to have been true. So the censorship turned out not to be for the common good, and should not have been followed or endorsed. But people supported such censorship truly believing they had the moral authority. So the difference between good law and bad law is not as clear cut as Farrell seems to think. The advice would Farrell/St. Thomas proposes to help us avoid these mistakes seems a lackluster.
I also was fascinated by his distinction between the Old Law as laid out by the Old Testament and the New Law laid out by Jesus. This was something that I never understood, nor does the non-Christian world. He essentially says that the Old Law was for a civilization in it's infancy to prepare the Jewish people for bringing forth the Messiah, while the New Law was for perfection. Well, if you've read the laws spelled out in books like Leviticus, you still may be scratching your head after reading Farrell. Bottom line, something still didn't add up for me.
Overall, I just found this book falls short of the first volume. If the first had any faults, it was that it wasn't easy for Farrell to translate medieval concepts of pure thought into language easier to grasp for readers who are not metaphysical philosophers or logicians. Here, he took his objective too far, and translated ideas that didn't need much translation. Therefore, both volumes falter on getting points across without the reader putting in twice the work at times to refer back to the source material and meditate on the information. Not that doing so would be a bad thing. This is, after all, a Companion to the Summa. But by this second volume, Farrell either gained way too much confidence in his ability to make the Summa relatable, or his work on the first volume scared him so much that he felt he had to work overtime to get points across.
Thomas Aquinas was using philosophical proofs to get to the existence of God. Centuries later, Kant would touch on these very proofs in his "Critique of Pure Reason" when he talked of antinomies in the Transcendental Dialectic section of that famous book. Though Kant does not cite Aquinas in the Critique, he goes through the same process as Aquinas. He presents a thesis that if every action in the universe has a cause, then at some point in space and time there had to be a necessary first cause, as infinity is a series of measurements that can never be finished, and thus can't be applied backwards so that there never was a beginning or first cause. Of course, Kant pulled a slick move and also proved the antithesis as well, thus saying that reason creates a conflict when it comes to understanding things outside our experience because our brains are not equipped that way. Therefore, Kant says that it is possible that God could be real (noumena), but like radio waves, our reason cannot deduce anything about him beyond our limited way we sense and interpret the universe. Aquinas, on the other hand, refused to go where Kant eventually did, and so he stopped at the thesis. Aquinas felt that reason dictated without error that there had to be a prime, immovable mover, and that mover is what is known as God.
This volume of Farrell's Companion does capture some of this essence of the Summa. Granted, the focus of this work was on particular questions in the Summa regarding happiness, not the existence of God. Yet, throughout the Summa, the point was to show how reason can take things we know from experience and work them back to God. Thus, all of Farrell's meanderings about football players and kings does essentially what St. Thomas was doing--deducing from a posteriori empirical knowledge that happiness comes from a loving God.
This is definitely a work that some people will get a lot out of. They will appreciate that Farrell is able to synthesize practical advice for modern life based on religious principles extracted from source material that is otherwise a very analytic and cerebral work of metaphysics. Other readers will be frustrated by how it seems to constantly stray from St. Thomas and become a bit of a sermon rather than a work of theology. The book is actually more cohesive than what may be initially apparent, as it is building layers of a case. But I do recognize the difficulty some may have with this one.
So while Volume One gets a solid four stars from me, Volume Two drops down to three.
