The Last Superstition: The Final Insult
Chapter 6: Irreducible teleology, cont.
Having exoriated biologists over the fact that popular science writers use terms like “purpose” and “blueprint”, Feser moves on to nonliving systems, in which he also sees purpose and intentionality. For instance, the water and rock cycles (I’d never heard of a “rock cycle” before, but okay):
The role of condensation in the water cycle, for example, is to bring about precipitation; the role of pressure in the rock cycle is, in conjunction with heat, to contribute to generating magma, and in the absence of heat to contribute to generating sedimentary rock; and so forth. Each stage has the production of some particular outcome or range of outcomes as an “end” or “goal” toward which it points. [p. 258]
Here, Feser implies that the water cycle is supposed to exist, and condensation exists to further that goal. Likewise, of course you have to have pressure, otherwise how can you have magma? It seems as though he is projecting his opinions onto the world so hard that he can’t imagine that maybe water does what water does, and it’s only because the temperature on the surface of this planet oscillates in a certain range that allows water to behave in such an interesting fashion.
Basic laws of nature
Moving on to fundamental science, Feser graces us with a rather interesting idea of how minds work:
Mental images are vague and indistinct when their objects are complex or detailed, but the related concepts or ideas are clear and distinct regardless of their complexity; for example, the concept of a chiliagon, or 1000-sided figure, is clearly different from the concept of a 999-sided figure, even though a mental image of a chiliagon is no different from a mental image of a 999-sided figure. [p. 260]
I’m not quite sure what he’s trying to say, though the best spin I can put on it is that we have trouble imagining complex things clearly. I agree, and this means that we need to be careful when thinking about complex things, because we’re likely to overlook something.
But since Feser brings this up in the context of thinking about abstract things, I have to wonder. When he talks about the possibility of purely material minds, he sounds like someone who thinks that a DVD has to have little pictures on it; that if you put a CD close enough to your ear, you’ll hear the music on it. Maybe I’m wrong; but that’s the impression I get, especially after the bit in Chapter 4 where he seemed to think that thinking about triangles would have to involve part of your brain becoming triangular.
He goes on for a bit against David Hume and complaining about the “anti-Aristotelian ideological program” (p. 261) of modern science. Basically, he tells us, science cannot proceed without Aristotle, but scientists are fiercely opposed to him on ideological grounds. Probably because they just want to sin, or something. In fact,
Despite the undeniable advances in empirical knowledge made during the last 300 plus years, then, the work of the scientists who made those advances simply does not support the philosophical interpretation of those advances put forward by the proponents of the “Mechanical Philosophy” and the contemporary materialists or naturalists who are their intellectual heirs [p. 264]
See, scientists are smart people who have been very successful at figuring out how the universe operates, so successful that we now take things like nuclear weapons and GPS receivers for granted. But they’re not smart enough to figure out the implications of their work.
If you look around the Internet, you can find any number of religious figures or just plain cranks who are convinced that their holy book, prophet, or whoever predicted various facts long before scientists did. They usually do this by taking some vague or poetic passage in scripture, combining it with some scientific discovery, and interpreting the former to describe the latter. For example, this page on Islam and embryology explains that
“The three veils of darkness” [in the Quran] may refer to: (l) the anterior abdominal wall; (2) the uterine wall; and (3) the amniochorionic membrane
And this page explains that “[he that] stretcheth out the heavens as a curtain” in the Bible refers to cosmic expansion.
Likewise, in this chapter, Feser talks about scientists rediscovering the genius of Aristotle. But it’s also painfully obvious that the scientific revolution did not begin in earnest with Aquinas, but rather several centuries later. That, combined with the fact that science has been so wonderfully successful despite the fact that the average scientist probably couldn’t give a summary of Aristotle’s or Aquinas’s ideas strongly suggests that they’re simply irrelevant to science.
It’s the moon, stupid
By this point, Feser thinks that he’s established that the millennia-old ideas of Aristotle, refined by Aquinas’s medieval insights, are correct. He bemoans the fact that they’ve fallen into obscurity:
But if Aristotle has, by virtue of developments in modern philosophy and science, had his revenge on those who sought to overthrow him at the dawn of the modern period, why is this fact not more widely recognized? One reason is the prevailing general ignorance about what the Aristotelian and Scholastic traditions really believed, what the actual intellectual and historical circumstances were that led to their replacement by modern philosophy in its various guises, and what the true relationship is between the latter and modern science. [p. 266]
The blame for the “general ignorance” part seems to land squarely on Feser’s shoulders. It’s up to him and his colleagues to educate the rest of us. But honestly, maybe ignorance is his ally: Feser’s exposition of Aristotle’s and Aquinas’s ideas makes it clear that they’re largely based on ignorance and superstition, and can be safely relegated to History of Ideas class, and ignored in everyday life.
He closes by quoting the proverb, “When the finger points at the moon, the idiot looks at the finger” (p. 267) as an analogy to the way objects “point to” things beyond themselves, but “the secularist” doesn’t realize this. Fittingly, he closes on an insult: “It’s the moon, stupid.” (p. 267)
