The Last Superstition: Software Is Immaterial

Chapter 4: Minds Are Not Material

In order to prove that human souls are immortal, Feser has to prove that there’s some part of a person that survives death, and the destruction of the body. If there’s a part of a human left behind when you remove the matter, that part must presumably be immaterial, and independent of the body (and in particular of the brain). Let’s watch how he does this:

Consider first that when we grasp the nature, essence, or form of a thing, it is necessarily one and the same form, nature, or essence that exists both in the thing and in the intellect. The form of triangularity that exists in our minds when we think about triangles is the same form that exists in actual triangles themselves; the form of “dogness” that exists in our minds when we think about dogs is the same form that exists in actual dogs; and so forth. If this weren’t the case, then we just wouldn’t really be thinking about triangles, dogs, and the like, since to think about these things requires grasping what they are, and what they are is determined by their essence or form. But now suppose that the intellect is a material thing – some part of the brain, or whatever. Then for the form to exist in the intellect is for the form to exist in a certain material thing. But for a form to exist in a material thing is just for that material thing to be the kind of thing the form is a form of; for example, for the form of “dogness” to exist in a certain parcel of matter is just for that parcel of matter to be a dog. And in that case, if your intellect was just the same thing as some part of your brain, it follows that that part of your brain would become a dog whenever you thought about dogs. “But that’s absurd!” you say. Of course it is; that’s the point. Assuming that the intellect is material leads to such absurdity; hence the intellect is not material. [p. 124]

Notice what he’s saying here: to make a triangle, you arrange matter in the shape of a triangle; to make a dog, you arrange atoms in a certain way, in the Form of a dog.

And, he tells us, in order to think about triangles, something in our cognitive process has to become like a triangle; to think about dogs, something has to become dog-like (including being dog-shaped). But since there’s no part of the brain (or, indeed, any other material part of the human body) that becomes triangular when we think of triangles, something else must be responsible for that aspect of cognition; something immaterial.

The most polite thing I can say here is “wow”. Clearly this is someone who doesn’t know the first thing about how software works, on the most basic level. I don’t expect Feser to be a programmer, but surely he realizes that the National Hurricane Center computers that simulate hurricanes don’t actually create rain and wind in the data center. That when you play World of Warcraft, there aren’t actually orcs running around somewhere.

(This reminds me of a post by Gil Dodgen at Uncommon Descent, about how a computer simulation of evolution would have to include random changes to the processor, OS, and so on. (My original response to that post here.))

Even if we granted Feser’s reasoning, above, it would only get him as far as “there’s more than just the brain; understanding the brain doesn’t mean that you understand the mind.” But he goes farther than that, telling us that “there is the fact that even though the intellect itself operates without any bodily organ” (p. 127).

If the soul can, unlike the form of a table, function apart from the matter it informs (as it does in thought), then it can also, and again unlike the form of a table, exist apart from the matter it informs, as a kind of incomplete substance. [p. 127]

Again, wow. This is like saying that since software is not hardware, it can run without any hardware. Or that since music comes down to vibrations, and since CDs don’t vibrate, that CDs aren’t involved in playing music. You wouldn’t expect to see tiny pictures if you look at a DVD through a microscope, or hear dialog if you listen to it closely enough, and yet this is the sort of mindset that Feser seems to be seriously considering, as far as I can tell.

I can understand Aristotle and Aquinas making these sorts of mistakes: they lived at a time when people didn’t really distinguish between a book, and the words in the book. So it’s natural that, in groping around for these concepts, that they would make some mistakes. But Feser doesn’t have this excuse. Not only do we distinguish between book-as-words and book-as-object, we can put a price tag on this difference: as I speak, the hardback edition of The Last Superstition sells for $18.85 at Amazon, while the Kindle ebook costs $7.36 less.

There’s a bit in The Hitchhiker’s Guide to the Galaxy where two philosophers object to the use of a computer to figure out the Great Question of Life, the Universe, and Everything. One of them says, “I mean what’s the use of our sitting up half the night arguing that there may or may not be a God if this machine only goes and gives us his bleeding phone number the next morning?” I feel we’re at that point with the “whatever it is that is the thing but isn’t matter”: Plato called it Form, Aristotle and Aquinas called it essence. We call it data, information, software, and we use it every day.

We understand software. Feser has no excuse for promulgating the sort of primitive thinking above.

Helpfully, Feser tells us why he doesn’t notice when his train of thought jumps the rails and plows across a field before getting stuck in a ditch:

Here, as elsewhere, the arguments we are considering are attempts at what I have been calling metaphysical demonstration, not probabilistic empirical theorizing. In each case, the premises are obviously true, the conclusion follows necessarily, and thus the conclusion is obviously true as well. That, at any rate, is what the arguments claim. If you’re going to refute them, then you need to show either that the premises are false or that the conclusion doesn’t really follow. […] The “findings of neuroscience” couldn’t refute these arguments any more than they could refute “2 + 2 = 4.” [pp. 125–126]

That is, Feser is so convinced that his premises are true, and that his reasoning is correct, that he doesn’t even bother with reality checks, though he does bring up science when it suits him:

When does the rational soul’s presence in the body begin? At conception. For a soul is just the form – the essence, nature, structure, organizational pattern – of a living thing, an organism. And the human organism, as we know from modern biology, begins at conception. [p. 128]

Not that he bothers citing any biologist to confirm this statement. Maybe this is one of those “obviously true” premises that he doesn’t feel the need to defend.

Far from any of this being undermined by modern science, it is confirmed by it. For the nature and structure of DNA is exactly the sort of thing we should expect to exist given an Aristotelian metaphysical conception of the world, and not at all what we would expect if materialism were true.

Oh, really? Then I’d love to see the book where Aquinas predicts the existence of a double-helix with “backbones” made of coal and phosphorus, scooping those atheist materialists, Francis Crick and James Watson, by centuries. Unless, of course, he’s just doing the same thing that every other apologist does: wait until scientists do the hard work of discovering something, then say, “Pfft! My god could’ve done that. In fact, he did, if you squint at this scripture just right.”

Naah, it’s definitely medieval prescience.

“Spirit Cooking”: They Got Nothin’

The latest thing conservatives have got a bug up their ass about concerns something called “Spirit Cooking”. This is an art project by artist Marina Abramovic from 1996. It’s presented as pages from a cookbook, including such “recipes” as

3 glasses of water
that a ruby has been soaking in for 3 days
1 pomegranate

which looks to me like par for the course for a performance artist in the 90s. Other “recipes” call for “fresh morning urine” OR “fresh breast milk with fresh sperm milk”. According to the Washington Times article, above, she sounds like a mystic, somewhat crunchy-granola, and provocative. Again, par for the course in the art world.

So why is this suddenly showing up in the political news section? Because WikiLeaks has released an email message from Tony Podesta to John Podesta, relaying an invitation to Abramovic’s Spirit Dinner event.

So we have a weird-ass artist. She knows Tony Podesta, who’s the brother of John Podesta, who’s Hillary Clinton’s campaign manager and generally an important person in American politics. She uses her connection with Tony to invite John, as you do.

And apparently the conclusion to draw here is that John Podesta is into drinking urine or satanic rituals or something, and by extension, that Hillary Clinton is unfit to be president. Or something like that.

If that’s the best they’ve got, I’m not impressed. Or rather, I’m impressed that people so disconnected from reality manage to tie their shoes in the morning.

The Last Superstition: Animal Souls

Chapter 4: Scholastic Aptitude

Having introduced his main themes in chapters 1-3, Feser now elaborates upon them, starting with

The Soul

a soul is just the form or essence of a living thing. [p. 121]

And the form or essence, you’ll recall, is the whatever-it-is that makes a thing the sort of thing that it is. For triangles, the essence is triangularity (i.e., being a three-sided polygon).

One might think, then, that the soul of a human would be whatever it means to be human. Humanity or humanness, that is. But from context, that doesn’t seem right: humanness is something shared by all people, while the soul has traditionally been an individual thing. That is, while Martha Washington and Nelson Mandela have the same essence of humanness, they have distinct souls.

He goes on to classify souls into a hierarchy: at the bottom are “nutritive souls”, which plants have, and allow them to take in nutrients and reproduce. Above that is the “sensory soul”, which does everything a nutritive soul does, plus sense the world around, and move. Nonhuman animals have sensory souls. And finally, there are “rational souls” — human souls — which have everything that sensory souls have, plus the capacity for abstract thought.

Clearly, this classification is based far more in medieval preconceptions than in modern biology. For one thing, the venus flytrap seems to have a sensory soul, since it clearly senses its environment. For another, there’s no mention of bacteria, which can fit in either category as well. (I’ll grant that, almost certainly, only animals can fit into the “rational” category.)

But the distinction between nutritive and sensory souls isn’t nearly as important as that between sensory and rational souls, since the point is to discuss the mind, and certain things that follow from that, like morality. And here is where Feser really ought to have done himself a favor and looked into current research on animal intelligence.

A quick Google search turned up this Scientific American article about, well, abstract reasoning in animals. I wasn’t surprised that apes exhibit abstract reasoning (the experiment was, roughly, to see whether orangutans and a gorilla could answer the question, “Here’s a picture; here’s another picture; is it the same kind of animal as the first picture?”), but I was surprised that dogs can exhibit abstract reasoning as well, being able to distinguish dogs from non-dogs by sight. Crows can this as well, distinguishing “this is a set of similar things” from “this is a set of dissimilar things”.

More recently, an experiment seems to have shown that apes have theory of mind. That is, gorillas and other apes can figure out what another individual believes, even when that belief is false.

Feser will, I am sure, reply that this isn’t the sort of high-level abstract reasoning that defines a rational soul, and put forth further criteria, but that’s exactly my point: the line between humans and other species isn’t nearly as wide as it might appear; certainly not as wide as Aristotle and Aquinas probably thought. And, of course, our ancestors evolved from clearly-non-rational animals to clearly-rational humans.

Do gorillas or orangutans have rational souls, if at least some of them can, at least on occasion, reason abstractly? It certainly seems to be one of their potentialities, as I understand Feser’s use of the term elsewhere.

More about rationality (emphasis and comments added):

Rationality – the ability to grasp forms or essences and to reason on the basis of them – has as its natural end or final cause the attainment of truth, of understanding the world around us. [Says who? I would have said this is the natural end of curiosity, not of rationality. — arensb] And free will has as its natural end or final cause the choice of those actions that best accord with the truth as it is discovered by reason, and in particular in accord with the truth about a human being’s own nature or essence. [What does this even mean? — arensb] That is, as we shall see, exactly what morality is from the point of view of Aristotle and Aquinas: the habitual choice of actions that further the hierarchically ordered natural ends entailed by human nature. [Who decides which ends are natural? — arensb] But the intellect’s capacity to know the truth is more fully realized the deeper one’s understanding of the nature of the world and the causes underlying it. And the deepest truth about the world, as we have seen, is that it is caused and sustained in being by God. The highest fulfillment of the distinctively human power of intellect, then, is, for Aristotle and Aquinas, to know God. And since the will’s natural end or purpose is to choose in accordance with the furtherance of those ends entailed by human nature, the highest fulfillment of free choice is to live in a way that facilitates the knowing of God. [p. 122]

The description of free will, here, is not one that I’ve ever seen. The core of free will, as I’ve usually heard it, is the ability to make decisions without external influence; what Feser is describing sounds more like “figuring out what’s true, the better to attain a desired goal”. The two concepts are related, but different.

The definition of morality also looks weird. Feser seems to be saying that morality involves learning to live in accordance with human nature. But as I think any parent will tell you, children need to be taught not to steal, or hit their siblings and playmates. And thus, contra Feser, morality seems to be about learning to overcome the less-desirable aspects of human nature, that we might live together with minimal friction.

I pointed out earlier some of what I saw as quite shoddy reasoning on Feser’s part, and why I didn’t find his arguments for God convincing. And given that, as he tells us, Aristotelianism/Thomism has been abandoned by modern scholar, neither do a lot of other people. And thus at a minimum, Feser ought to use his rationality to come up with a better way of getting at the truth, either a better argument for God or an admission that the ones he’s using aren’t all that good.

All in all, though, this paragraph exhibits, in spades, the sort of thinking that gives theology a bad name: redefining common terms in unfamiliar ways, and making questionable-at-best leaps of logic from one clause to the next, to arrive at one’s desired conclusion.

The Last Superstition: The First Cause

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?”

He continues:

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.

The Last Superstition: The Unmoved Mover

Chapter 3: The Existence of God: The Unmoved Mover

First of all, “movement” in this context really means change of any kind, not necessarily motion through space. Yes, I know this is annoying and confusing.

Feser introduces two kinds of causes: accidentally ordered and essentially ordered. (Here, “accidentally” doesn’t mean “by misfortune”, and “essentially” doesn’t mean “more or less”; they’re terms of art.) A father causes a son, but if the father dies, the son can keep going; so the father and son are “accidentally ordered”. But if your hand pushes a stick that in turn pushes a stone along the ground, the stone will stop moving when the stick stops pushing on it, and the stick will stop moving when the hand stops pushing it; so the hand, stick, and stone are “essentially ordered”. You can have an arbitrarily deep essentially ordered stack of things that depend on each other, each one depending on the previous item on the list:

These sorts of series paradigmatically trace, not backwards in time, but rather “downward” in the present moment, since they are series in which each member depends simultaneously on other members which simultaneously depend in turn on yet others, on so on. In this sort of series, the later members have no independent causal power of their own, being mere instruments of a first member. Hence if there were no first member, such a series would not exist at all. [p. 93]

The emphasis on “simultaneously” is Feser’s, and at first I thought he was using the word in some technical sense that doesn’t mean “in the same instant of time”, rather the same way that “accidentally” doesn’t mean “by accident”, above. But no, apparently he does[1], and that’s a problem.

Aquinas and his predecessors couldn’t have known this, of course, but nothing is instantaneous. The stick in the example acts more like a very fast spring: when the hand pushes on it, it compresses the top end of the stick a little bit; this causes a wave to travel very quickly down the length of the stick and push on the rock, so really the rock starts moving a tiny fraction of a second after the hand starts pushing on it (and likewise when the hand stops pushing).

And even if Feser didn’t know this, surely he has a driver’s license, which means he must have taken a test that required him to know about braking distance, which is a problem because it takes time for a nerve impulse to travel down from the brain to the driver’s hands and feet. So the rock will stop moving a larger fraction of a second after the person holding the stick decides to stop pushing.

Or consider a mountain stream that’s fed by a glacier, which in turn is built up by regular snowfall. If the weather patterns change and snow stops falling, the glacier will melt and the stream will stop flowing… eventually. A century might elapse between the cause stopping, and the effect stopping.

So simultaneity doesn’t work, here (and I’m not even bringing up relativity and the fact that two observers might not agree on whether two events are simultaneous). But perhaps it’s possible to salvage this idea: the big distinction seems to be between effects that get kickstarted by their cause, and ones that are sustained by their cause. So let’s go with that. More on this in a bit.

Another problem with the stick example is that the stone doesn’t stop simply because the hand stops pushing it: as Newton explained, four hundred years after Aquinas, a body in motion continues to move at a constant velocity, unless acted upon by an outside force. The outside force, in this case, being friction with he ground. It must be remembered that Newton’s first law was quite counterintuitive and revolutionary for its time, so we can forgive Aquinas for not counting the earth as an important actor in this example, but Feser ought to know better.

At any rate, we were talking about essentially-ordered series, where each element is sustained by the previous one.

How far can it go? Not that far, actually; certainly not to infinity. [p. 95]

Okay, why not? Feser doesn’t say. He uses the example of an infinitely-long train, where car 1 pulls the caboose, car 2 pulls car 1, car 3 pulls car 2, and so on, but there’s no engine at the head of the train.

Well, yes. Infinities are counterintuitive (see this short video about the Hilbert Hotel, which has an infinite number of rooms). And the idea of an inifinitely-long causal chain is unsettling (at least, I find it unsettling), but I see no reason a priori why there can’t be an infinitely-long causal chain.

Worse yet, since time does weird things at huge relativistic scales, and at tiny quantum scales, I can’t rule out the possibility of a closed loop of causes, where A causes B and B causes A.

But okay, maybe there’s something I’m overlooking. Where’s Feser going with this?

Now, a first mover in such a series must be itself unmoved or unchanging; for if it was moving or changing – that is, going from potential to actual – then there would have to be something outside it actualizing its potential, in which case it wouldn’t be the first mover. […] The series can only stop, that is to say, with a being that is pure actuality (or “Pure Act,” to use the Scholastic phrase), with no admixture of potentiality whatsoever. And having no potentiality to realize or actualize, such a being could not possibly move or change. [pp. 95–96]

[…] Aquinas goes on to say: “. . . and this we call God.” [p. 96]

So that was a long and bumpy road to say that “God” is the first cause.

For some reason, Feser never explores any cause-effect relationship other than chains. We saw above that the rock stopped moving for two reasons: the earth and gravity exerted friction, and the hand and stick were no longer applying sufficient force to overcome this friction. So an effect can have multiple causes, and those causes can in turn have multiple causes, and it’s not always as simple as A causes B causes C. Perhaps there are gazillions of uncaused causes all around us.

And now we see why Feser insisted that essentially-ordered causes and effects be simultaneous: he wants there to be a god now. Just having sustaining causes, as with the glacier and stream, would imply that it’s possible that God started and sustained the universe (like the snow on the glacier), but then disappeared, and the universe will eventually notice and stop running, but hasn’t done so just yet.

Of course, all this makes the unmoved mover sound rather abstract, more like an abstract principle than the sort of anthropomorphic deity who cures cancer when prayed to.

“Well, uh, OK, then,” you might be thinking; “but what does that have to do with God as the average person understands Him?” A lot, actually. For once we have this much in hand, we can go on to deduce all sorts of things about what a being of Pure Actuality would have to be like, and it turns out that such a being would have to be like the God of traditional Western religious belief.

How? Because Courtier’s Reply is how. Aquinas and other theologians have written thousands of pages on the subject — thousands! — therefore it must be so.

Okay, that’s not entirely fair:

Now recall the Aristotelian principle that a cause cannot give what it does not have, so that the cause of a feature must have that feature either “formally” or “eminently”; that is, if it does not have the feature itself (as a cigarette lighter, which causes fire, is not itself on fire), it must have a feature that is higher up in the hierarchy of attributes (as the cigarette lighter has the power to generate fire). But the Unmoved Mover, as the source of all change, is the source of things coming to have the attributes they have. Hence He has these attributes eminently if not formally. That includes every power, so that He is all-powerful. It also includes the intellect and will that human beings possess (features far up in the hierarchy of attributes of created things, as we will see in the next chapter), so that He must be said to have intellect and will, and thus personality, in an analogical sense. Indeed, he must have them in the highest degree, lacking any of the limitations that go along with being a material creature or otherwise having potentiality. Hence He not only has knowledge, but knowledge without limit, being all-knowing. [p. 98]

“And that, my liege, is how we know the Earth to be banana-shaped.”

What a remarkable reversal! At the beginning of the paragraph, Feser tells us that a lighter can cause fire despite not being itself on fire; at the end, he says that God caused intelligence, and therefore must be intelligent. Presumably the explanation is that God’s intelligence is eminent, i.e. God is intelligent in the same way that a car’s cigarette lighter is on fire, which is to say, it isn’t. We now see why Feser defined causation the way he did, using language that suggested that things have attributes inside them that they can release onto other things: he’s defined God to be an abstract principle, something perhaps akin to the Tao, but he also wants this god to have intelligence, benevolence, and so on. He squares this particular circle by playing word games, saying that a cause contains the effect “eminently”, where “eminently” means “doesn’t contain”.

Does this mean that the Unmoved Mover has what we would regard as negative or defective features too – blindness, disease, heroin addiction, etc., “eminently” if not “formally”? Not at all. For every such feature is what the Scholastics called a “privation,” the absence of a positive feature rather than a positive feature in its own right. [p. 99]

I suppose it follows that God does not lack a yeast infection, because that would be a privation. I guess it’s possible that “positive feature” here means “feature that someone wants; an asset”, but that would be begging the question. (Also, I thought addiction was basically poorly-tuned brain chemistry. How does it qualify as a “privation”?)

And while I’m sure the thousands of pages have an answer, it seems to me that the unmoved mover defined above isn’t the Christian God: Feser is quite insistent that the unmoved mover has no potentialities, i.e., it’s static; there’s nothing it can become that it isn’t already; no attribute it might gain that it doesn’t already have.

But Jesus’ life and resurrection is an important part of Christianity, or at least of Feser’s flavor of Christianity, Catholicism. According to the story, Jesus lived and was divine, and then died, at least his human body did. So God wasn’t incarnated, and then was incarnated, and then wasn’t. So incarnation must have been one of Yahweh’s original potentialities, which means that he can’t be the unmoved mover described above.

So maybe Muslims are right after all: Allah has no son.

[1] In a post on the subject, he had to reach into the depths of science fiction to come up with a non-simultaneous example.

Chapter 3: The Existence of God

So when people say “God”, what sort of entity are they talking about?

Many secularists seem hell-bent (if you’ll pardon the expression) on pretending that religious people in general believe in a God so anthropomorphic that only a child or the most ignorant peasant could take the question of His existence seriously even for a moment. I know I’ve heard the stupid “Easter Bunny” comparison often enough to make me want to scream [p.87]

I’m afraid Feser needs to come down from the ivory tower more often. He’s making the argument that Daniel Fincke satirized at Camels With Hammers. If no (or only an insignificant minority of) religious people in general think that God is, basically, an old man who watches everyone, then who keeps buying Chick tracts and leaving them in public places? Who keeps handing me flyers with titles like “Heaven is real and hell is real”?

Feser prefers sneering over hard data, but there is data out there. This Gallup poll from June 2016, for example, tells us that 72% of Americans believe in angels, 71% in heaven, 64% in hell, and 615 in the devil. The Pew research Center’s 2015 Religious Landscape Survey also tells us that 31% of American adults think scripture is the word of God and should be taken literally. Gallup also tells us that around 40% of Americans think that “God created human beings pretty much in their present form at one time within the last 10,000 years or so”.

As I write this, Mother Teresa of Kolkata was canonized less than a week ago, something that required her to perform two miracles. In this case, two people were allegedly healed of their diseases (at least one while receiving medical care) and the Catholic church’s ruling that these are miracles means that yes, God somehow arranged for the natural course of nature to be suspended so that these people could be healed.

In fairness to Feser, though, I must point out that I wasn’t able to find any surveys on whether or not God has a beard.

But the point is that a lot of people do believe in God as a being who, if not man-shaped, certainly does many things that humans do, like watch over the ones he loves and intervene on their behalf. Feser can dismiss people who believe this as ignorant peasants if he likes, but he can’t claim that they’re an insignificant minority. And if this many people believe in “so anthropomorphic” a God, then Feser’s side has a lot of work to do, educating the people in the pews. And in the meantime, if he wants to say that there’s no man in the sky who’ll help you find a parking space if you pray to him, well, welcome to this side of the debate.

The Last Superstition: Reasoning With Aquinas

Chapter 3: Aquinas’s logical reasoning

Eventually, Feser settles down to tell us a bit about Aquinas. In particular, his method of reasoning:

What Aquinas is doing can be understood by comparison with the sort of reasoning familiar from geometry and mathematics in general. Take the Pythagorean theorem, for example. Once you understand the axiomatic method, the definition of triangularity, and so forth, and then reason through a particular proof of the theorem, you can see that the theorem must be true, and necessarily so. It is not a “hypothesis” “postulated” to “explain” certain “evidence,” and it is not merely “probable.” [p.81]

Metaphysical arguments of the sort Aquinas is interested in combine elements of both these other forms of reasoning: they take obvious, though empirical, starting points, and try to show that from these starting points, together with certain conceptual premises, certain metaphysical conclusions follow necessarily. [p.83]

In other words, Aquinas is trying to prove God the way you’d prove a mathematical theorem, through logic and reason, and most emphatically not through observation. You could sum this up as “it stands to reason”.

There are a few problems with this approach: while mathematics is undeniably useful, it also describes a lot of things that don’t actually exist. For instance, Wikipedia defines a Hilbert space as a generalization of Euclidean space, one that can have thousands, or even an infinite number of dimensions, instead of our paltry three or four or twenty-some.

More trivially, mathematics tells us that if you put six quadrillion apples into a basket, and add another eight quadrillion apples, you’ll have fourteen quadrillion apples in your basket. This is obviously false because there aren’t that many apples on the planet, and no basket that can hold them all. In this case, the math describes a world with fourteen quadrillion apples, which is not the world we live in.

The point of this isn’t that mathematics is broken, but rather that it’s important to make sure that you’ve picked the sort of mathematics that describes the world you’re living in, and specifically the problem you’re studying. Don’t go beyond its area of applicability: Euclidean geometry might work on the scale of a town, but not that of a continent, where you have to take the earth’s curvature into account, lest you get wrong answers.

Furthermore, the longer a demonstration goes on, the greater the odds that it’ll contain some error in reasoning, perhaps a subtle one. When Andrew Wiles presented his proof of Fermat’s last theorem, several reviewers went over it looking for errors (and found some). That’s why, when you’re drawing conclusions about the real world, it’s important to have a reality check from time to time to make sure you haven’t gone off the rails. But Feser sees no need for this.

In a criticism of “scientism”, Feser says that science makes certain metaphysical assumptions:

Of its very nature, scientific investigation takes for granted such assumptions as that: there is a physical world existing independently of our minds; this world is characterized by various objective patterns and regularities; our senses are at least partially reliable sources of information about this world; there are objective laws of logic and mathematics that apply to the objective world outside our minds; our cognitive powers – of concept-formation, reasoning from premises to a conclusion, and so forth – afford us a grasp of these laws and can reliably take us from evidence derived from the senses to conclusions about the physical world; the language we use can adequately express truths about these laws and about the external world; and so on and on. [p. 84]

Maybe a scientist or philosopher of science will correct me, but this doesn’t seem quite right:

there is a physical world existing independently of our minds
I think this is a working assumption, one that could be proved wrong.

this world is characterized by various objective patterns and regularities
I’d call this a discovery, not an assumption. Things could conceivably have been otherwise; Greg Egan explores this possibility in his novel Schild’s Ladder in which there is a region of space where there don’t seem to be any consistent laws of physics; every experiment gives inconsistent results. My point is that if such a zone existed, we’d know it. So it seems reasonable to assume regularity, at least until there’s reason to think otherwise.

our senses are at least partially reliable sources of information about this world
there are objective laws of logic and mathematics that apply to the objective world outside our minds
our cognitive powers – of concept-formation, reasoning from premises to a conclusion, and so forth – afford us a grasp of these laws and can reliably take us from evidence derived from the senses to conclusions about the physical world
These all seem to be conclusions, or at worst working assumptions.

the language we use can adequately express truths about these laws and about the external world
But natural languages like English and Greek are often not up to the task of describing reality. That’s why the language of science is math, and why Newton and Leibnitz had to invent calculus. And of course every discipline invents its own jargon, to describe the objects and ideas specific to that discipline, as well as mathematical techniques for those areas.

It’s true that some of these may be basic assumptions, or at least working assumptions. In fact, Feser could just as easily have listed “God is not messing around with my experiment” as a working assumption. But most of them seem at least potentially falsifiable, like in the movie The Matrix, where Neo, the main character, did find out that he was a brain in a vat. I also like this article that uses supernova SN1987A to show that the speed of light was the same 300,000 years ago as it is today, using trigonometry, astronomical observations, and the decay rate of cobalt to cross-check each other.

This cross-checking and verification are things that make science so robust and reliable, and they’re things that I don’t see in Feser’s presentation. And given that he seems to be basing his reasoning on what a medieval monk thought was obvious, I think there’s good reason to be skeptical of his conclusions.

The Last Superstition: Let’s Meet Aquinas

Chapter 3: Getting Medieval

Having laid the groundwork in Chapter 2, Feser now moves on to the star of the show, Thomas Aquinas. He opens the chapter with a story of Aquinas overlooking a woman’s achievements, and instead interrupting her with a comment about her body:

he once came upon “a holy nun who used to be levitated in ecstasy.” His reaction was to comment on how very large her feet were. “This made her come out of her ecstasy in indignation at his rudeness, whereupon he gently advised her to seek greater humility.” [p. 74]

And one about attacking a woman, when his brothers locked him up in the family castle (bold added):

When the brothers upped the ante by sending a prostitute into his room, he famously chased her away with a flaming brand snatched from the fireplace and then used it to draw a cross on the wall, before which he prayed for, and received, the gift of lifelong chastity. [p. 74]

Section What Aquinas didn’t say

Feser starts out by spending five pages berating Dawkins, Hitchens, Harris, and Dennett. This can be skipped.

I should note that Feser berates both Dawkins and Dennett for either mangling or not devoting much space to the classical — i.e., Aristotle’s and Aquinas’s — proofs for God. But he also keeps telling us what a mistake it was for the world of philosophy to abandon these ideas. In other words, he criticizes Dawkins and Dennett for not paying attention to ideas that are not widely embraced even by philosophers and theologians. If he can’t convince his colleagues to accept Thomism, why should the rest of us spend any time on it?

The other thing I’d like to pause on is this quotation on p.79:

The author of a sympathetic recent study of Dennett’s philosophy acknowledges that the “consensus evaluation” of Dennett’s work among his academic peers is that while it is “undeniably creative and important,” it “lacks philosophical depth and is not systematic.” [Tadeusz Zawidzki, Dennett (Onewold Publications, 2007), p. ix]

This quotation comes from the opening paragraph of the preface:

I came to this project with some standard assumptions about Dennett’s work. I have been reading Dennett since deciding to major in philosophy as an undergraduate, and over the years I had come to accept the consensus evaluation of his work: although undeniably creative and important, it supposedly lacks philosophical depth and is not systematic. Consensus has it that Dennett’s approach is diffuse and piecemeal, involving clever discussions of specific problems at the intersection of philosophy and the sciences of human nature, without the backing of an overarching, philosophical system. Many of Dennett’s admirers, skeptical of the excesses of traditional philosophical systems, see this approach as a virtue (Rorty 1993, pp. 191–192; Ross 2000, pp. 16–23). Indeed, Dennett himself often blithely dismisses the importance of philosophical system-building (Ross 2000, p. 13; Dennett 2000, pp. 356, 359).

Writing this book has significantly changed my view of Dennett’s work. If the reader comes away with anything from the following, I want it to be an appreciation of the fact that Dennett’s work constitutes a deeply coherent philosophical system, founded on a few consistently applied principles.

I’ve underlined the parts that Feser quoted, and added bold emphasis.

Feser is doing the same thing that creationists do when they quote Darwin saying that the evolution of the eye seems absurd: taking part of a rhetorical construct and quoting it out of context to make it sound like a flaw.

Since the rebuttal of Feser’s implication is right there in the second paragraph; since he carefully selected this quotation to be technically true (well, some people say that Dennett’s a hack); and since he deliberately selected his quotations to just remove “supposedly”; it’s clear to me that Feser knew exactly what he was doing: selectively quoting Zawidzki to make him say something he doesn’t agree with. So I’m going to call him dishonest.

The Last Superstition: Aristotelianism Recap

Chapter 2: Aristotelianism recap

As you may have noticed by how long that last post was, I can’t seem to go more than a few pages without stumbling on something illogical, or nonsensical, or just plain wrong. It’s not because I’m trying to be picky or combative; it’s just that I keep trying to apply the ideas Feser presents to real life, and failing.

I asked earlier which Forms an iPhone 7 instantiates. One could also ask how to determine what a thing’s final cause is. Feser never tells us. At times, he talks about such things being obvious (e.g., that various organs have obvious purposes (p.70); but then, what is the purpose of the human appendix, or of male nipples?), but this doesn’t help with non-obvious cases.

So aristotelianism sounds appealing on the surface, but turns out not to be a useful way of thinking about reality.

Now, I’m sure someone can tell me why I’m wrong about every example I bring up, but in this respect, aristotelianism is no different from homeopathy or astrology: practitioners of those disciplines are quick to dismiss any objection or anomalous result by saying that you forgot to take into account Saturn’s rotation, or the precise minute of your birth, or suggest a better substance to use from the catalog, or whatever. After a while, it becomes apparent that the discipline has a large grab-bag of excuses for every occasion.

One problem with final causes specifically is that they seem to be a way to impose teleology on the universe. It’s very tempting to look at the world and say that hearts are for pumping blood, or that the sun is for light and warmth. It’s obvious. But, to quote Granny Weatherwax in Wyrd Sisters, “I’ll grant you it’s obvious. Trouble is, just because things are obvious doesn’t mean they’re true.”

Creationists, in my experience, are prone to this sort of teleological thinking. It takes effort to show them that it’s far better to ask “what can this organ do?” rather than “what is this organ for?” For instance, a butterfly’s wing helps it fly. It is supremely good at this task. But it also serves to advertise its colors to potential mates. In the case of monarch butterflies, the wings also advertise to predators that “this butterfly tastes awful.”

This will become significant later on. For now, suffice it to say that Feser seems to take it for granted that everything or nearly everything — at least, everything important under discussion — has a final cause, that is, that it’s for something, or that it’s oriented toward some goal or purpose.

The Last Superstition: Aristotle’s Metaphysics

Chapter 2: Greeks Bearing Gifts, Aristotle’s metaphysics

We now come to Aristotle, and one of Feser’s central points (emphasis in the original):

How significant is Aristotle? Well, I wouldn’t want to exaggerate, so let me put it this way: Abandoning Aristotelianism, as the founders of modern philosophy did, was the single greatest mistake ever made in the entire history of Western thought. [p.51]

At least he doesn’t mess about.

[This abandonment’s] logical implications can also be seen in today’s headlines: in the abortion industry’s slaughter of millions upon millions of unborn human beings; in the judicial murder of Terri Schiavo (as Nat Hentoff aptly labeled it) and the push for euthanasia generally; in the mostly pointless and certainly point-missing debate between Darwinians and “Intelligent Design” advocates; in the movement for “same-sex marriage” and the sexual revolution generally; and a thousand other things besides. [p.51, same paragraph as previous quotation]

PS, he is not a crackpot.

A central part of Aristotle’s philosophy is “actuality” vs. “potentiality”. In considering the example of a rubber ball that melts and becomes gooey:

Aristotle replies: Even if the gooeyness itself doesn’t yet exist in the ball, the potential for gooeyness does exist in it, and this, together with some external influence that actualizes this potential (e.g. heat), suffices to show how the change can occur. [p.53]

This, by the way, is supposed to put us on the way to understanding that there must be a god.

So basically, a thing’s “actuality” is the way it that thing is, or exists, or is configured, and its “potentialities” are all the ways it could possibly be. If I’m understanding correctly, actuality is the object’s position in phase space, and its potentialities are all the positions reachable from its current position.

Feser reminds us that a potential can’t actualize itself, and this seems trivially true: if you have a blue rubber ball, and it might be painted red, then “being red” isn’t something that can paint a ball. Likewise for all the other potentialities. But he also tells us,

Consider also that if a potential could actualize itself, there would be no way to explain why it does so at one time rather than another. [p. 54]

This seems like a non sequitur. I said above that potential states aren’t the sort of thing that do things, but even if we take the sentence above to mean “If a thing could change on its own, there would be no way …”, I don’t see how the second half necessarily follows.

Superficially, it seems obvious, but if there’s one thing science should have taught us, it’s that “obvious” is not the same as “true”: the sun does not revolve around the earth, objects in motion don’t stop on their own (more on this later), fast-moving objects get shorter, and so on. So I’d like to see a few more intermediary steps between “an object can’t change on its own” and “there can be no explanation for why it changes at time t0 and not t1.

But there’s another problem with the above, beside the non sequitur: let’s say that Feser is right, and there’s some phenomenon for which there’s no explanation beyond “that’s just the way it is”.

So what?

I know that this makes us uncomfortable. I, for one, would find that rather unsettling, because it does seem as though everything has a good explanation. But so what? The universe is not obligated to conform to our desires. And we see all the time that people accept bogus explanations because they’re more satisfying than saying “I don’t know” or “that’s just the way it is”. But this self-deception is exactly the sort of thing we need to guard against if we want to know the truth.

Form and matter

For Aristotle, Feser tells us, an object has two important properties: its matter — the stuff it’s made of — and its form — the way the matter is put together. That is, you can have a bunch of hydrogen, carbon, oxygen, etc. atoms (matter), and if you assemble them into the shape of a chair (form), then you’ve got a chair. Seems pretty straightforward.

The four causes

The four causes are Aristotle’s answer to four questions that can be asked of anything: “What is it made of?” (material cause), “What’s its shape or form?” (formal cause), “What caused it?” (efficient cause), and “What’s it for?” (final cause).

The first two seem out of place, since they’re not really causes as that word is currently understood, but maybe there are historical reasons. The third one, efficient cause, is just your garden-variety cause: “Why is the water boiling? Because it’s on a hot stove.” That sort of thing.

But final cause deserves closer scrutiny. For one thing, asking “what is X for?” presupposes that X is for something, and that’s far from obvious. But Feser tells us that final causality can be found everywhere:

I also gave the functions of bodily organs as an example, and it is indeed the most obvious and compelling sort of example to give. But Aristotle takes final causation or goal-directedness to exist throughout inorganic nature as well. The moon is “directed toward” movement around the earth, as a kind of “goal.”

The moon is there so it can orbit the earth. You heard it here first, folks.

To be sure, Feser makes it clear that he doesn’t think the moon is conscious, and doesn’t want or intend to orbit the earth. Rather, the moon is for orbiting in the same way, I guess, that a knife is for slicing. But yes, at the end of the day, Feser tells us, the moon has a purpose: orbiting.

This is one of many “you have got to be kidding me!” moments in this book.

Feser says, here and elsewhere in the book, that everything or nearly everything has a final cause, but he never supports this claim. He says that Aristotle believed that everything has a final cause, but never presents a case for why we should take this as more than opinion.

He talks a lot about the opinions of “modern philosophers, scientists, and intellectuals in general [p. 71]” on final causes, but his case has several problems: he never quotes his opponents directly, doesn’t cite them, and doesn’t even tell us who these people are.

And when he does present their case, he has them saying that there are no final causes, e.g:

And this is precisely why causation has become such a problem for modern thinkers. Famously, they deny that there really are any final causes at all, appearances notwithstanding. [p.64]

Of course, the converse of “everything has a final cause” isn’t “nothing has a final cause”. It’s “it’s not true that everything has a final cause.” Either Feser’s interlocutors fail basic logic, or else he’s setting up straw men.

Feser does give us specific examples of the sorts of final causes he’s talking about: that the point of the moon is to orbit the earth, or that “an oak tree is the final cause of an acorn” [p.115], so I’m willing to accept that some things have final causes. But that doesn’t imply that everything has a final cause, or that the interesting things (human life, the universe, etc.) have final causes, or that those causes are interesting.

Let’s say it turns out that the purpose or final cause of the universe is to expand. Well, fine. It can do that on its own. The rest of us can ignore that and get on with our own final purposes.

Formal and eminent causation

One last thing before moving on:

whatever is in the effect must in some sense be contained in the cause as well. The basic idea is that a cause cannot give to its effect what it does not have to give [p. 67]

This seems like a very odd thing to say, or at least an odd way of saying it. Yes, a hot fire makes a room hot, a cold ice cube makes a drink cold, a red paint brush makes a canvas red, and so on. But of course, there are other ways of causing something:

Or, to take another example, the cause of a fire might itself be on fire, as when a torch is used to start a brushfire, or it may instead have the power to produce fire, as a cigarette lighter has even when it is not being used. The traditional way of making this distinction is to say that a cause has the feature that it generates in the effect “formally” in the first sort of case (e.g. when both the cause and the effect are red or on fire) and “eminently” in the second sort of case (e.g. when the cause is not itself red or on fire but has an inherent power to produce redness or fire). If a cause didn’t contain all the features of its effect either formally or eminently, there would be no way to account for how the effect came about in just the way it did. Again, a cause cannot give to its effect what it does not have to give. [p. 68]

Which is to say that a cause can produce an effect either by transferring an attribute from itself to something else, or by some other means. It seems odd, even reminiscent of phlogiston to put it the way Feser does: the cigarette lighter doesn’t have heat inside it the way an orange contains juice. Feser has a reason for putting it this way, but since he’s laying groundwork for his main argument, it’ll have to wait.
