Chapter 3: The First Cause
If you thought Feser’s “Unmoved mover” argument was just mental masturbation, the sort of sophistry that gives philosophy a bad reputation and evokes the image of a tweed-wearing ivory tower professor using five-dollar words to ask meaningless questions, then you can skip his First Cause section, because it’s more of the same.
He begins by asking,
In order for the universe to undergo change, it obviously must exist. In particular, it must persist in existence from moment to moment. So why does it do so? [p. 109]
In the previous section, we saw that Aquinas assumed, as so many did, that objects in motion stop of their own accord, and need something to keep them going; and that Newton showed that that’s not a general rule, it’s just the way things usually play out on Earth.
Feser’s question here seems to stem from the same source: that there has to be some sustaining force for the universe to not collapse on itself and disappear in an instant. It seems that “things are the way they were a moment ago” isn’t the sort of thing that needs an explanation. If the universe did disappear, that would be a big change, something that required an explanation.
But Feser prefers to go on for a few pages about essences and “creating cause[s]”. I’ll spare you. The main question is, if B caused A, and C caused B, what happens as you go up the chain of causes?
No, the only thing that could possibly stop the regress and explain the entire series would be a being who is, unlike the things that make up the universe, not a compound of essence and existence. That is to say, it would have to be a being whose essence just is existence; or, more precisely, a being to whom the essence/existence distinction doesn’t apply at all, who is pure existence, pure being, full stop: not a being, strictly speaking, but Being Itself. [p. 108]
I’m not sure why the above is a better ultimate explanation than “it’s just that way” (I mean better in the sense of helping us understand the world around us, not in the sense of being emotionally satisfying.)
You might wonder why, if the cause of the universe is, ultimately, existence, why we need a separate word, especially one with as much baggage as the word “God”. In the next paragraph, he tells us: the first cause is the prime mover, and “Hence, equally obviously, the First Cause is God. [p. 108]”
The Supreme Intelligence
True to form, Feser starts and ends this section with several pages of complaining about New Atheists and others. When he finally gets around to making his argument, he starts by raising the question of why the universe exhibits any regularities:
But there is no way to make sense of these regularities apart from the notion of final causation, of things being directed toward an end or goal. For it is not just the case that a struck match regularly generates fire, heat, and the like; it regularly generates fire and heat specifically, rather than ice, or the smell of lilacs, or the sound of a trumpet. It is not just the case that the moon regularly orbits the earth in a regular pattern; it orbits the earth specifically, rather than quickly swinging out to Mars and back now and again, or stopping dead for five minutes here and there, or dipping down toward the earth occasionally and then quickly popping back up. [p. 114]
This seems equivalent to asking, “why is it, in the general case, that things left to their own devices act in certain ways but not others?”
And so on for all the innumerable regularities that fill the universe at any moment. In each case, the causes don’t simply happen to result in certain effects, but are evidently and inherently directed toward certain specific effects as toward a “goal.” [p. 115]
Note the teleology — or, if you will, the question-begging: things behave in a certain way, so that must be their end-aim, purpose, or “goal”. But you can’t have a purpose without someone deciding what the purpose is:
Yet it is impossible for anything to be directed toward an end unless that end exists in an intellect which directs the thing in question toward it. [p. 115]
I believe this is known as painting a target around the arrow: the moon orbits the earth, therefore its purpose is to orbit the earth. But since you can’t have a purpose without a mind, someone must have set it up that way.
Could such a Supreme Intelligence possibly be anything less than God? It could not. For whatever ultimately orders things to their ends must also be the ultimate cause of those things [p. 117]
By this logic, the architect who decided to assemble bricks into a house — that the house is the end goal and purpose of the bricks — is also the person who baked the bricks. It seems apparent that Feser is not interested in following evidence and logic wherever they lead, but rather in finding paths to his favorite conclusion. That is, apologetics.
