Fire, Water, and Numbers

Fire vs. Water

All things are water,” says Thales.

“All things are fire,” says Heraclitus.

“Wait,” says David Hume’s Philo. “You both agree that all things are made up of one substance. Thales, you prefer to call it water, and Heraclitus, you prefer to call it fire. But isn’t that merely a verbal dispute? According to both of you, whatever you point at is fundamentally the same fundamental stuff. So whether you point at water or fire, or anything else, for that matter, you are always pointing at the same fundamental stuff. Where is the real disagreement?”

Philo has a somewhat valid point here, and I mentioned the same thing in the linked post referring to Thales. Nonetheless, as I also said in the same post, as well as in the discussion of the disagreement about God, while there is some common ground, there are also likely remaining points of disagreement. It might depend on context, and perhaps the disagreement is more about the best way of thinking about things than about the things themselves, somewhat like discussing whether the earth or the universe is the thing spinning, but Heraclitus could respond, for example, by saying that thinking of the fundamental stuff as fire is more valid because fire is constantly changing, while water often appears to be completely still, and (Heraclitus claims) everything is in fact constantly changing. This could represent a real disagreement, but it is not a large one, and Thales could simply respond: “Ok, everything is flowing water. Problem fixed.”

Numbers

It is said that Pythagoras and his followers held that “all things are numbers.” To what degree and in what sense this attribution is accurate is unclear, but in any case, some people hold this very position today, even if they would not call themselves Pythagoreans. Thus for example in a recent episode of Sean Carroll’s podcast, Carroll speaks with Max Tegmark, who seems to adopt this position:

0:23:37 MT: It’s squishy a little bit blue and moose like. [laughter] Those properties, I just described don’t sound very mathematical at all. But when we look at it, Sean through our physics eyes, we see that it’s actually a blob of quarks and electrons. And what properties does an electron have? It has the property, minus one, one half, one, and so on. We, physicists have made up these nerdy names for these properties like electric charge, spin, lepton number. But it’s just we humans who invented that language of calling them that, they are really just numbers. And you know as well as I do that the only difference between an electron and a top quark is what numbers its properties are. We have not discovered any other properties that they actually have. So that’s the stuff in space, all the different particles, in the Standard Model, you’ve written so much nice stuff about in your books are all described by just by sets of numbers. What about the space that they’re in? What property does the space have? I think I actually have your old nerdy non-popular, right?

0:24:50 SC: My unpopular book, yes.

0:24:52 MT: Space has, for example, the property three, that’s a number and we have a nerdy name for that too. We call it the dimensionality of space. It’s the maximum number of fingers I can put in space that are all perpendicular to each other. The name dimensionality is just the human language thing, the property is three. We also discovered that it has some other properties, like curvature and topology that Einstein was interested in. But those are all mathematical properties too. And as far as we know today in physics, we have never discovered any properties of either space or the stuff in space yet that are actually non-mathematical. And then it starts to feel a little bit less insane that maybe we are living in a mathematical object. It’s not so different from if you were a character living in a video game. And you started to analyze how your world worked. You would secretly be discovering just the mathematical workings of the code, right?

Tegmark presumably would believe that by saying that things “are really just numbers,” he would disagree with Thales and Heraclitus about the nature of things. But does he? Philo might well be skeptical that there is any meaningful disagreement here, just as between Thales and Heraclitus. As soon as you begin to say, “all things are this particular kind of thing,” the same issues will arise to hinder your disagreement with others who characterize things in a different way.

The discussion might be clearer if I put my cards on the table in advance:

First, there is some validity to the objection, just as there is to the objection concerning the difference between Thales and Heraclitus.

Second, there is nonetheless some residual disagreement, and on that basis it turns out that Tegmark and Pythagoras are more correct than Thales and Heraclitus.

Third, Tegmark most likely does not understand the sense in which he might be correct, rather supposing himself correct the way Thales might suppose himself correct in insisting, “No, things are really not fire, they are really water.”

Mathematical and non-mathematical properties

As an approach to these issues, consider the statement by Tegmark, “We have never discovered any properties of either space or the stuff in space yet that are actually non-mathematical.”

What would it look like if we found a property that was “actually non-mathematical?” Well, what about the property of being blue? As Tegmark remarks, that does not sound very mathematical. But it turns out that color is a certain property of a surface regarding how it reflects flight, and this is much more of a “mathematical” property, at least in the sense that we can give it a mathematical description, which we would have a hard time doing if we simply took the word “blue.”

So presumably we would find a non-mathematical property by seeing some property of things, then investigating it, and then concluding, “We have fully investigated this property and there is no mathematical description of it.” This did not happen with the color blue, nor has it yet happened with any other property; either we can say that we have not yet fully investigated it, or we can give some sort of mathematical description.

Tegmark appears to take the above situation to be surprising. Wow, we might have found reality to be non-mathematical, but it actually turns out to be entirely mathematical! I suggest something different. As hinted by connection with the linked post, things could not have turned out differently. A sufficiently detailed analysis of anything will be a mathematical analysis or something very like it. But this is not because things “are actually just numbers,” as though this were some deep discovery about the essence of things, but because of what it is for people to engage in “a detailed analysis” of anything.

Suppose you want to investigate some thing or some property. The first thing you need to do is to distinguish it from other things or other properties. The color blue is not the color red, the color yellow, or the color green.

Numbers are involved right here at the very first step. There are at least three colors, namely red, yellow, and blue.

Of course we can find more colors, but what if it turns out there seems to be no definite number of them, but we can always find more? Even in this situation, in order to “analyze” them, we need some way of distinguishing and comparing them. We will put them in some sort of order: one color is brighter than another, or one length is greater than another, or one sound is higher pitched than another.

As soon as you find some ordering of that sort (brightness, or greatness of length, or pitch), it will become possible to give a mathematical analysis in terms of the real numbers, as we discussed in relation to “good” and “better.” Now someone defending Tegmark might respond: there was no guarantee we would find any such measure or any such method to compare them. Without such a measure, you could perhaps count your property along with other properties. But you could not give a mathematical analysis of the property itself. So it is surprising that it turned out this way.

But you distinguished your property from other properties, and that must have involved recognizing some things in common with other properties, at least that it was something rather than nothing and that it was a property, and some ways in which it was different from other properties. Thus for example blue, like red, can be seen, while a musical note can be heard but not seen (at least by most people.) Red and blue have in common that they are colors. But what is the difference between them? If we are to respond in any way to this question, except perhaps, “it looks different,” we must find some comparison. And if we find a comparison, we are well on the way to a mathematical account. If we don’t find a comparison, people might rightly complain that we have not yet done any detailed investigation.

But to make the point stronger, let’s assume the best we can do is “it looks different.” Even if this is the case, this very thing will allow us to construct a comparison that will ultimately allow us to construct a mathematical measure. For “it looks different” is itself something that comes in degrees. Blue looks different from red, but orange does so as well, just less different. Insofar as this judgment is somewhat subjective, it might be hard to get a great deal of accuracy with this method. But it would indeed begin to supply us with a kind of sliding scale of colors, and we would be able to number this scale with the real numbers.

From a historical point of view, it took a while for people to realize that this would always be possible. Thus for example Isidore of Seville said that “unless sounds are held by the memory of man, they perish, because they cannot be written down.” It was not, however, so much ignorance of sound that caused this, as ignorance of “detailed analysis.”

This is closely connected to what we said about names. A mathematical analysis is a detailed system of naming, where we name not only individual items, but also various groups, using names like “two,” “three,” and “four.” If we find that we cannot simply count the thing, but we can always find more examples, we look for comparative ways to name them. And when we find a comparison, we note that some things are more distant from one end of the scale and other things are less distant. This allows us to analyze the property using real numbers or some similar mathematical concept. This is also related to our discussion of technical terminology; in an advanced stage any science will begin to use somewhat mathematical methods. Unfortunately, this can also result in people adopting mathematical language in order to look like their understanding has reached an advanced stage, when it has not.

It should be sufficiently clear from this why I suggested that things could not have turned out otherwise. A “non-mathematical” property, in Tegmark’s sense, can only be a property you haven’t analyzed, or one that you haven’t succeeded in analyzing if you did attempt it.

The three consequences

Above, I made three claims about Tegmark’s position. The reasons for them may already be somewhat clarified by the above, but nonetheless I will look at this in a bit more detail.

First, I said there was some truth in the objection that “everything is numbers” is not much different from “everything is water,” or “everything is fire.” One notices some “hand-waving,” so to speak, in Tegmark’s claim that “We, physicists have made up these nerdy names for these properties like electric charge, spin, lepton number. But it’s just we humans who invented that language of calling them that, they are really just numbers.” A measure of charge or spin or whatever may be a number. But who is to say the thing being measured is a number? Nonetheless, there is a reasonable point there. If you are to give an account at all, it will in some way express the form of the thing, which implies explaining relationships, which depends on the distinction of various related things, which entails the possibility of counting the things that are related. In other words, someone could say, “You have a mathematical account of a thing. But the thing itself is non-mathematical.” But if you then ask them to explain that non-mathematical thing, the new explanation will be just as mathematical as the original explanation.

Given this fact, namely that the “mathematical” aspect is a question of how detailed explanations work, what is the difference between saying “we can give a mathematical explanation, but apart from explanations, the things are numbers,” and “we can give a mathematical explanation, but apart from explanations, the things are fires?”

Exactly. There isn’t much difference. Nonetheless, I made the second claim that there is some residual disagreement and that by this measure, the mathematical claim is better than the one about fire or water. Of course we don’t really know what Thales or Heraclitus thought in detail. But Aristotle, at any rate, claimed that Thales intended to assert that material causes alone exist. And this would be at least a reasonable understanding of the claim that all things are water, or fire. Just as Heraclitus could say that fire is a better term than water because fire is always changing, Thales, if he really wanted to exclude other causes, could say that water is a better term than “numbers” because water seems to be material and numbers do not. But since other causes do exist, the opposite is the case: the mathematical claim is better than the materialistic ones.

Many people say that Tegmark’s account is flawed in a similar way, but with respect to another cause; that is, that mathematical accounts exclude final causes. But this is a lot like Ed Feser’s claim that a mathematical account of color implies that colors don’t really exist; namely they are like in just being wrong. A mathematical account of color does not imply that things are not colored, and a mathematical account of the world does not imply that final causes do not exist. As I said early on, a final causes explains why an efficient cause does what it does, and there is nothing about a mathematical explanation that prevents you from saying why the efficient cause does what it does.

My third point, that Tegmark does not understand the sense in which he is right, should be plain enough. As I stated above, he takes it to be a somewhat surprising discovery that we consistently find it possible to give mathematical accounts of the world, and this only makes sense if we assume it would in theory have been possible to discover something else. But that could not have happened, not because the world couldn’t have been a certain way, but because of the nature of explanation.

Mind of God

Reconciling Theism and Atheism

In his Dialogues Concerning Natural Religion, David Hume presents Philo as arguing that the disagreement between theists and atheists is merely verbal:

All men of sound reason are disgusted with verbal disputes, which abound so much in philosophical and theological inquiries; and it is found, that the only remedy for this abuse must arise from clear definitions, from the precision of those ideas which enter into any argument, and from the strict and uniform use of those terms which are employed. But there is a species of controversy, which, from the very nature of language and of human ideas, is involved in perpetual ambiguity, and can never, by any precaution or any definitions, be able to reach a reasonable certainty or precision. These are the controversies concerning the degrees of any quality or circumstance. Men may argue to all eternity, whether HANNIBAL be a great, or a very great, or a superlatively great man, what degree of beauty CLEOPATRA possessed, what epithet of praise LIVY or THUCYDIDES is entitled to, without bringing the controversy to any determination. The disputants may here agree in their sense, and differ in the terms, or vice versa; yet never be able to define their terms, so as to enter into each other’s meaning: Because the degrees of these qualities are not, like quantity or number, susceptible of any exact mensuration, which may be the standard in the controversy. That the dispute concerning Theism is of this nature, and consequently is merely verbal, or perhaps, if possible, still more incurably ambiguous, will appear upon the slightest inquiry. I ask the Theist, if he does not allow, that there is a great and immeasurable, because incomprehensible difference between the human and the divine mind: The more pious he is, the more readily will he assent to the affirmative, and the more will he be disposed to magnify the difference: He will even assert, that the difference is of a nature which cannot be too much magnified. I next turn to the Atheist, who, I assert, is only nominally so, and can never possibly be in earnest; and I ask him, whether, from the coherence and apparent sympathy in all the parts of this world, there be not a certain degree of analogy among all the operations of Nature, in every situation and in every age; whether the rotting of a turnip, the generation of an animal, and the structure of human thought, be not energies that probably bear some remote analogy to each other: It is impossible he can deny it: He will readily acknowledge it. Having obtained this concession, I push him still further in his retreat; and I ask him, if it be not probable, that the principle which first arranged, and still maintains order in this universe, bears not also some remote inconceivable analogy to the other operations of nature, and, among the rest, to the economy of human mind and thought. However reluctant, he must give his assent. Where then, cry I to both these antagonists, is the subject of your dispute? The Theist allows, that the original intelligence is very different from human reason: The Atheist allows, that the original principle of order bears some remote analogy to it. Will you quarrel, Gentlemen, about the degrees, and enter into a controversy, which admits not of any precise meaning, nor consequently of any determination? If you should be so obstinate, I should not be surprised to find you insensibly change sides; while the Theist, on the one hand, exaggerates the dissimilarity between the Supreme Being, and frail, imperfect, variable, fleeting, and mortal creatures; and the Atheist, on the other, magnifies the analogy among all the operations of Nature, in every period, every situation, and every position. Consider then, where the real point of controversy lies; and if you cannot lay aside your disputes, endeavour, at least, to cure yourselves of your animosity.

To what extent Hume actually agrees with this argument is not clear, and whether or not a dispute is verbal or real is itself like Hume’s questions about greatness or beauty, that is, it is a matter of degree. Few disagreements are entirely verbal. In any case, I largely agree with the claim that there is little real disagreement here. In response to a question on the about page of this blog, I referred to some remarks about God by Roderick Long:

Since my blog has wandered into theological territory lately, I thought it might be worth saying something about the existence of God.

When I’m asked whether I believe in God, I usually don’t know what to say – not because I’m unsure of my view, but because I’m unsure how to describe my view. But here’s a try.

I think the disagreement between theism and atheism is in a certain sense illusory – that when one tries to sort out precisely what theists are committed to and precisely what atheists are committed to, the two positions come to essentially the same thing, and their respective proponents have been fighting over two sides of the same shield.

Let’s start with the atheist. Is there any sense in which even the atheist is committed to recognising the existence of some sort of supreme, eternal, non-material reality that transcends and underlies everything else? Yes, there is: namely, the logical structure of reality itself.

Thus so long as the theist means no more than this by “God,” the theist and the atheist don’t really disagree.

Now the theist may think that by God she means something more than this. But likewise, before people knew that whales were mammals they thought that by “whale” they meant a kind of fish. What is the theist actually committed to meaning?

Well, suppose that God is not the logical structure of the universe. Then we may ask: in what relation does God stand to that structure, if not identity? There would seem to be two possibilities.

One is that God stands outside that structure, as its creator. But this “possibility” is unintelligible. Logic is a necessary condition of significant discourse; thus one cannot meaningfully speak of a being unconstrained by logic, or a time when logic’s constraints were not yet in place.

The other is that God stands within that structure, along with everything else. But this option, as Wittgenstein observed, would downgrade God to the status of being merely one object among others, one more fragment of contingency – and he would no longer be the greatest of all beings, since there would be something greater: the logical structure itself. (This may be part of what Plato meant in describing the Form of the Good as “beyond being.”)

The only viable option for the theist, then, is to identify God with the logical structure of reality. (Call this “theological logicism.”) But in that case the disagreement between the theist and the atheist dissolves.

It may be objected that the “reconciliation” I offer really favours the atheist over the theist. After all, what theist could be satisfied with a deity who is merely the logical structure of the universe? Yet in fact there is a venerable tradition of theists who proclaim precisely this. Thomas Aquinas, for example, proposed to solve the age-old questions “could God violate the laws of logic?” and “could God command something immoral?” by identifying God with Being and Goodness personified. Thus God is constrained by the laws of logic and morality, not because he is subject to them as to a higher power, but because they express his own nature, and he could not violate or alter them without ceasing to be God. Aquinas’ solution is, essentially, theological logicism; yet few would accuse Aquinas of having a watered-down or crypto-atheistic conception of deity. Why, then, shouldn’t theological logicism be acceptable to the theist?

A further objection may be raised: Aquinas of course did not stop at the identification of God with Being and Goodness, but went on to attribute to God various attributes not obviously compatible with this identification, such as personality and will. But if the logical structure of reality has personality and will, it will not be acceptable to the atheist; and if it does not have personality and will, then it will not be acceptable to the theist. So doesn’t my reconciliation collapse?

I don’t think so. After all, Aquinas always took care to insist that in attributing these qualities to God we are speaking analogically. God does not literally possess personality and will, at least if by those attributes we mean the same attributes that we humans possess; rather he possesses attributes analogous to ours. The atheist too can grant that the logical structure of reality possesses properties analogous to personality and will. It is only at the literal ascription of those attributes that the atheist must balk. No conflict here.

Yet doesn’t God, as understood by theists, have to create and sustain the universe? Perhaps so. But atheists too can grant that the existence of the universe depends on its logical structure and couldn’t exist for so much as an instant without it. So where’s the disagreement?

But doesn’t God have to be worthy of worship? Sure. But atheists, while they cannot conceive of worshipping a person, are generally much more open to the idea of worshipping a principle. Again theological logicism allows us to transcend the opposition between theists and atheists.

But what about prayer? Is the logical structure of reality something one could sensibly pray to? If so, it might seem, victory goes to the theist; and if not, to the atheist. Yet it depends what counts as prayer. Obviously it makes no sense to petition the logical structure of reality for favours; but this is not the only conception of prayer extant. In Science and Health, for example, theologian M. B. Eddy describes the activity of praying not as petitioning a principle but as applying a principle:

“Who would stand before a blackboard, and pray the principle of mathematics to solve the problem? The rule is already established, and it is our task to work out the solution. Shall we ask the divine Principle of all goodness to do His own work? His work is done, and we have only to avail ourselves of God’s rule in order to receive His blessing, which enables us to work out our own salvation.”

Is this a watered-down or “naturalistic” conception of prayer? It need hardly be so; as the founder of Christian Science, Eddy could scarcely be accused of underestimating the power of prayer! And similar conceptions of prayer are found in many eastern religions. Once again, theological logicism’s theistic credentials are as impeccable as its atheistic credentials.

Another possible objection is that whether identifying God with the logical structure of reality favours the atheist or the theist depends on how metaphysically robust a conception of “logical structure” one appeals to. If one thinks of reality’s logical structure in realist terms, as an independent reality in its own right, then the identification favours the theist; but if one instead thinks, in nominalist terms, that there’s nothing to logical structure over and above what it structures, then the identification favours the atheist.

This argument assumes, however, that the distinction between realism and nominalism is a coherent one. I’ve argued elsewhere (see here and here) that it isn’t; conceptual realism pictures logical structure as something imposed by the world on an inherently structureless mind (and so involves the incoherent notion of a structureless mind), while nominalism pictures logical structure as something imposed by the mind on an inherently structureless world (and so involves the equally incoherent notion of a structureless world). If the realism/antirealism dichotomy represents a false opposition, then the theist/atheist dichotomy does so as well. The difference between the two positions will then be only, as Wittgenstein says in another context, “one of battle cry.”

Long is trying too hard, perhaps. As I stated above, few disagreements are entirely verbal, so it would be strange to find no disagreement at all, and we could question some points here. Are atheists really open to worshiping a principle? Respecting, perhaps, but worshiping? A defender of Long, however, might say that “respect” and “worship” do not necessarily have any relevant difference here, and this is itself a merely verbal difference signifying a cultural difference. The theist uses “worship” to indicate that they belong to a religious culture, while the atheist uses “respect” to indicate that they do not. But it would not be easy to find a distinct difference in the actual meaning of the terms.

In any case, there is no need to prove that there is no difference at all, since without a doubt individual theists will disagree on various matters with individual atheists. The point made by both David Hume and Roderick Long stands at least in a general way: there is far less difference between the positions than people typically assume.

In an earlier post I discussed, among other things, whether the first cause should be called a “mind” or not, discussing St. Thomas’s position that it should be, and Plotinus’s position that it should not be. Along the lines of the argument in this post, perhaps this is really an argument about whether or not you should use a certain analogy, and the correct answer may be that it depends on your purposes.

But what if your purpose is simply to understand reality? Even if it is, it is often the case that you can understand various aspects of reality with various analogies, so this will not necessarily provide you with a definite answer. Still, someone might argue that you should not use a mental analogy with regard to the first cause because it will lead people astray. Thus, in a similar way, Richard Dawkins argued that one should not call the first cause “God” because it would mislead people:

Yes, I said, but it must have been simple and therefore, whatever else we call it, God is not an appropriate name (unless we very explicitly divest it of all the baggage that the word ‘God’ carries in the minds of most religious believers). The first cause that we seek must have been the simple basis for a self-bootstrapping crane which eventually raised the world as we know it into its present complex existence.

I will argue shortly that Dawkins was roughly speaking right about the way that the first cause works, although as I said in that earlier post, he did not have a strong argument for it other than his aesthetic sense and the kinds of explanation that he prefers. In any case, his concern with the name “God” is the “baggage” that it “carries in the minds of most religious believers.” That is, if we say, “There is a first cause, therefore God exists,” believers will assume that their concrete beliefs about God are correct.

In a similar way, someone could reasonably argue that speaking of God as a “mind” would tend to lead people into error by leading them to suppose that God would do the kinds of the things that other minds, namely human ones, do. And this definitely happens. Thus for example, in his book Who Designed the Designer?, Michael Augros argues for the existence of God as a mind, and near the end of the book speculates about divine revelation:

I once heard of a certain philosopher who, on his deathbed, when asked whether he would become a Christian, admitted his belief in Aristotle’s “prime mover”, but not in Jesus Christ as the Son of God. This sort of acknowledgment of the prime mover, of some sort of god, still leaves most of our chief concerns unaddressed. Will X ever see her son again, now that the poor boy has died of cancer at age six? Will miserable and contrite Y ever be forgiven, somehow reconciled to the universe and made whole, after having killed a family while driving drunk? Will Z ever be brought to justice, having lived out his whole life laughing at the law while another person rotted in jail for the atrocities he committed? That there is a prime mover does not tell us with sufficient clarity. Even the existence of an all-powerful, all-knowing, all-good god does not enable us to fill in much detail. And so it seems reasonable to suppose that god has something more to say to us, in explicit words, and not only in the mute signs of creation. Perhaps he is waiting to talk to us, biding his time for the right moment. Perhaps he has already spoken, but we have not recognized his voice.

When we cast our eye about by the light of reason in his way, it seems there is room for faith in general, even if no particular faith can be “proved” true in precisely the same way that it can be “proved” that there is a god.

The idea is that given that God is a mind, it follows that it is fairly plausible that he would wish to speak to people. And perhaps that he would wish to establish justice through extraordinary methods, and that he might wish to raise people from the dead.

I think this is “baggage” carried over from Augros’s personal religious views. It is an anthropomorphic mistake, not merely in the sense that he does not have a good reason for such speculation, but in the sense that such a thing is demonstrably implausible. It is not that the divine motives are necessarily unknown to us, but that we can actually discover them, at least to some extent, and we will discover that they are not what he supposes.

Divine Motives

How might one know the divine motives? How does one read the mind of God?

Anything that acts at all does it what it does ultimately because of what it is. This is an obvious point, like the point that the existence of something rather than nothing could not have some reason outside of being. In a similar way, “what is” is the only possible explanation for what is done, since there is nothing else there to be an explanation. And in every action, whether or not we are speaking of the subject in explicitly mental terms or not, we can always use the analogy of desires and goals. In the linked post, I quote St. Thomas as speaking of the human will as the “rational appetite,” and the natural tendency of other things as a “natural appetite.” If we break down the term “rational appetite,” the meaning is “the tendency to do something, because of having a reason to do it.” And this fits with my discussion of human will in various places, such as in this earlier post.

But where do those reasons come from? I gave an account of this here, arguing that rational goals are a secondary effect of the mind’s attempt to understand itself. Of course human goals are complex and have many factors, but this happens because what the mind is trying to understand is complicated and multifaceted. In particular, there is a large amount of pre-existing human behavior that it needs to understand before it can attribute goals: behavior that results from life as a particular kind of animal, behavior that results from being a particular living thing, and behavior that results from having a body of such and such a sort.

In particular, human social behavior results from these things. There was some discussion of this here, when we looked at Alexander Pruss’s discussion of hypothetical rational sharks.

You might already see where this is going. God as the first cause does not have any of the properties that generate human social behavior, so we cannot expect his behavior to resemble human social behavior in any way, as for example by having any desire to speak with people. Indeed, this is the argument I am making, but let us look at the issue more carefully.

I responded to the “dark room” objection to predictive processing here and here. My response depends both the biological history of humans and animals in general, and to some extent on the history of each individual. But the response does not merely explain why people do not typically enter dark rooms and simply stay there until they die. It also explains why occasionally people do do such things, to a greater or lesser approximation, as with suicidal or extremely depressed people.

If we consider the first cause as a mind, as we are doing here, it is an abstract immaterial mind without any history, without any pre-existing behaviors, without any of the sorts of things that allow people to avoid the dark room. So while people will no doubt be offended by the analogy, and while I will try to give a more pleasant interpretation later, one could argue that God is necessarily subject to his own dark room problem: there is no reason for him to have any motives at all, except the one which is intrinsic to minds, namely the motive of understanding. And so he should not be expected to do anything with the world, except to make sure that it is intelligible, since it must be intelligible for him to understand it.

The thoughtful reader will object: on this account, why does God create the world at all? Surely doing and making nothing at all would be even better, by that standard. So God does seem to have a “dark room” problem that he does manage to avoid, namely the temptation to nothing at all. This is a reasonable objection, but I think it would lead us on a tangent, so I will not address it at this time. I will simply take it for granted that God makes something rather than nothing, and discuss what he does with the world given that fact.

In the previous post, I pointed out that David Hume takes for granted that the world has stable natural laws, and uses that to argue that an orderly world can result from applying those laws to “random” configurations over a long enough time. I said that one might accuse him of “cheating” here, but that would only be the case if he intended to maintain a strictly atheistic position which would say that there is no first cause at all, or that if there is, it does not even have a remote analogy with a mind. Thus his attempted reconciliation of theism and atheism is relevant, since it seems from this that he is aware that such a strict atheism cannot be maintained.

St. Thomas makes a similar connection between God as a mind and a stable order of things in his fifth way:

The fifth way is taken from the governance of the world. We see that things which lack intelligence, such as natural bodies, act for an end, and this is evident from their acting always, or nearly always, in the same way, so as to obtain the best result. Hence it is plain that not fortuitously, but designedly, do they achieve their end. Now whatever lacks intelligence cannot move towards an end, unless it be directed by some being endowed with knowledge and intelligence; as the arrow is shot to its mark by the archer. Therefore some intelligent being exists by whom all natural things are directed to their end; and this being we call God.

What are we are to make of the claim that things act “always, or nearly always, in the same way, so as to obtain the best result?” Certainly acting in the same way would be likely to lead to similar results. But why would you think it was the best result?

If we consider where we get the idea of desire and good, the answer will be clear. We don’t have an idea of good which is completely independent from “what actually tends to happen”, even though this is not quite a definition of the term either. So ultimately St. Thomas’s argument here is based on the fact that things act in similar ways and achieve similar results. The idea that it is “best” is not an additional contribution.

But now consider the alternative. Suppose that things did not act in similar ways, or that doing so did not lead to similar results. We would live in David Hume’s non-inductive world. The result is likely to be mathematically and logically impossible. If someone says, “look, the world works in a coherent way,” and then attempts to describe how it would look if it worked in an incoherent way, they will discover that the latter “possibility” cannot be described. Any description must be coherent in order to be a description, so the incoherent “option” was never a real option in the first place.

This argument might suggest that the position of Plotinus, that mind should not be attributed to God at all, is the more reasonable one. But since we are exploring the situation where we do make that attribution, let us consider the consequences.

We argued above that the sole divine motive for the world is intelligibility. This requires coherence and consistency. It also requires a tendency towards the good, for the above mentioned reasons. Having a coherent tendency at all is ultimately not something different from tending towards good.

The world described is arguably a deist world, one in which the laws of nature are consistently followed, but God does nothing else in the world. The Enlightenment deists presumably had various reasons for their position: criticism of specific religious doctrines, doubts about miracles, and an aesthetic attraction to a perfectly consistent world. But like Dawkins with his argument about God’s simplicity, they do not seem (to me at least) to have had very strong arguments. That does not prove that their position was wrong, and even their weaker arguments may have had some relationship with the truth; even an aesthetic attraction to a perfectly consistent world has some connection with intelligibility, which is the actual reason for the world to be that way.

Once again, as with the objection about creating a world at all, a careful reader might object that this argument is not conclusive. If you have a first cause at all, then it seems that you must have one or more first effects, and even if those effects are simple, they cannot be infinitely simple. And given that they are not infinitely simple, who is to set the threshold? What is to prevent one or more of those effects from being “miraculous” relative to anything else, or even from being something like a voice giving someone a divine revelation?

There is something to this argument, but as with the previous objection, I will not be giving my response here. I will simply note for the moment that it is a little bit strained to suggest that such a thing could happen without God having an explicit motive of “talking to people,” and as argued above, such a motive cannot exist in God. That said, I will go on to some other issues.

As the Heavens are Higher

Apart from my arguments, it has long been noticed in the actual world that God seems much more interested in acting consistently than in bringing about any specific results in human affairs.

Someone like Richard Dawkins, or perhaps Job, if he had taken the counsel of his wife, might respond to the situation in the following way. “God” is not an appropriate name for a first cause that acts like this. If anything is more important to God than being personal, it would be being good. But the God described here is not good at all, since he doesn’t seem to care a bit about human affairs. And he inflicts horrible suffering on people just for the sake of consistency with physical laws. Instead of calling such a cause “God,” why don’t we call it “the Evil Demon” or something like that?

There is a lot that could be said about this. Some of it I have already said elsewhere. Some of it I will perhaps say at other times. For now I will make three brief points.

First, ensuring that the world is intelligible and that it behaves consistently is no small thing. In fact it is a prerequisite for any good thing that might happen anywhere and any time. We would not even arrive at the idea of “good” things if we did not strive consistently for similar results, nor would we get the idea of “striving” if we did did not often obtain them. Thus it is not really true that God has no interest in human affairs: rather, he is concerned with the affairs of all things, including humans.

Second, along similar lines, consider what the supposed alternative would be. If God were “good” in the way you wish, his behavior would be ultimately unintelligible. This is not merely because some physical law might not be followed if there were a miracle. It would be unintelligible behavior in the strict sense, that is, in the sense that no explanation could be given for why God is doing this. The ordinary proposal would be that it is because “this is good,” but when this statement is a human judgement made according to human motives, there would need to be an explanation for why a human judgement is guiding divine behavior. “God is a mind” does not adequately explain this. And it is not clear that an ultimately unintelligible world is a good one.

Third, to extend the point about God’s concern with all things, I suggest that the answer is roughly speaking the one that Scott Alexander gives non-seriously here, except taken seriously. This answer depends on an assumption of some sort of modal realism, a topic which I was slowly approaching for some time, but which merits a far more detailed discussion, and I am not sure when I will get around to it, if ever. The reader might note however that this answer probably resolves the question about “why didn’t God do nothing at all” by claiming that this was never an option anyway.

Anticipations of Darwin

I noted here that long before Darwin, there was fairly decent evidence for some sort of theory of evolution, even evidence available from the general human experience of plant and animal life, without deep scientific study.

As said in the earlier post, Aristotle notes that Empedocles hypothesized something along the lines of natural selection:

Wherever then all the parts came about just what they would have been if they had come to be for an end, such things survived, being organized spontaneously in a fitting way; whereas those which grew otherwise perished and continue to perish, as Empedocles says his ‘man-faced ox-progeny’ did.

Since Aristotle is arguing against Empedocles, we should be cautious in assuming that the characterization of his position is entirely accurate. But as presented by Aristotle, the position is an argument against the existence of final causes: since things can be “organized spontaneously” in the way “they would have been if they had come to be for an end,” there is no reason to think they in fact came to be for an end.

This particular conclusion, namely that in such a process nothing comes to be for an end, is a mistake, based on the assumption that different kinds of causes are mutually exclusive, rather than recognizing that different kinds of causes are different ways of explaining one and the same thing. But the general idea regarding what happened historically is correct: good conditions are more capable of persisting, bad conditions less so, and thus over time good conditions tend to predominate.

Other interesting anticipations may be found in Ibn Khaldun‘s book, The Muqaddimah, published in 1377. For example we find this passage:

It should be known that we — may God guide you and us — notice that this world with all the created things in it has a certain order and solid construction. It shows nexuses between causes and things caused, combinations of some parts of creation with others, and transformations of some existent things into others, in a pattern that is both remarkable and endless. Beginning with the world of the body and sensual perception, and therein first with the world of the visible elements, (one notices) how these elements are arranged gradually and continually in an ascending order, from earth to water, (from water) to air, and (from air) to fire. Each one of the elements is prepared to be transformed into the next higher or lower one, and sometimes is transformed. The higher one is always finer than the one preceding it. Eventually, the world of the spheres is reached. They are finer than anything else. They are in layers which are inter­connected, in a shape which the senses are able to perceive only through the existence of motions. These motions provide some people with knowledge of the measurements and positions of the spheres, and also with knowledge of the existence of the essences beyond, the influence of which is noticeable in the spheres through the fact (that they have motion).

One should then look at the world of creation. It started out from the minerals and progressed, in an ingenious, gradual manner, to plants and animals. The last stage of minerals is connected with the first stage of plants, such as herbs and seedless plants. The last stage of plants, such as palms and vines, is connected with the first stage of animals, such as snails and shellfish which have only the power of touch. The word “connection” with regard to these created things means that the last stage of each group is fully prepared to become the first stage of the next group.

The animal world then widens, its species become numerous, and, in a gradual process of creation, it finally leads to man, who is able to think and to reflect. The higher stage of man is reached from the world of the monkeys, in which both sagacity and perception are found, but which has not reached the stage of actual reflection and thinking. At this point we come to the first stage of man after (the world of monkeys). This is as far as our (physical) observation extends.

It is possible that he makes his position clearer elsewhere (I have not read the entire work.) The passage here does not explicitly assert that humans arose from lower animals, but does suggest it, correctly associating human beings with monkeys in particular, even if some of his other connections are somewhat strange. In other words, both here and elsewhere, he speaks of one stage of things being “prepared to become” another stage, and says that this transition sometimes happens: “Each one of the elements is prepared to be transformed into the next higher or lower one, and sometimes is transformed.”

While Ibn Khaldun is at least suggesting that we notice a biological order that corresponds to some degree to an actual historical order, we do not see in this text any indication of what the mechanism is supposed to be. In contrast, Empedocles gives us a mechanism but no clarity regarding historical order. Admittedly, this may be an artifact of the fact that I have not read more of Ibn Khaldun and the fact that we have only fragments from Empedocles.

One of the strongest anticipations of all, although put in very general terms, can be found in David Hume’s Dialogues Concerning Natural Religion, in the following passage:

Besides, why may not motion have been propagated by impulse through all eternity, and the same stock of it, or nearly the same, be still upheld in the universe? As much is lost by the composition of motion, as much is gained by its resolution. And whatever the causes are, the fact is certain, that matter is, and always has been, in continual agitation, as far as human experience or tradition reaches. There is not probably, at present, in the whole universe, one particle of matter at absolute rest.

And this very consideration too, continued PHILO, which we have stumbled on in the course of the argument, suggests a new hypothesis of cosmogony, that is not absolutely absurd and improbable. Is there a system, an order, an economy of things, by which matter can preserve that perpetual agitation which seems essential to it, and yet maintain a constancy in the forms which it produces? There certainly is such an economy; for this is actually the case with the present world. The continual motion of matter, therefore, in less than infinite transpositions, must produce this economy or order; and by its very nature, that order, when once established, supports itself, for many ages, if not to eternity. But wherever matter is so poised, arranged, and adjusted, as to continue in perpetual motion, and yet preserve a constancy in the forms, its situation must, of necessity, have all the same appearance of art and contrivance which we observe at present. All the parts of each form must have a relation to each other, and to the whole; and the whole itself must have a relation to the other parts of the universe; to the element in which the form subsists; to the materials with which it repairs its waste and decay; and to every other form which is hostile or friendly. A defect in any of these particulars destroys the form; and the matter of which it is composed is again set loose, and is thrown into irregular motions and fermentations, till it unite itself to some other regular form. If no such form be prepared to receive it, and if there be a great quantity of this corrupted matter in the universe, the universe itself is entirely disordered; whether it be the feeble embryo of a world in its first beginnings that is thus destroyed, or the rotten carcass of one languishing in old age and infirmity. In either case, a chaos ensues; till finite, though innumerable revolutions produce at last some forms, whose parts and organs are so adjusted as to support the forms amidst a continued succession of matter.

Suppose (for we shall endeavour to vary the expression), that matter were thrown into any position, by a blind, unguided force; it is evident that this first position must, in all probability, be the most confused and most disorderly imaginable, without any resemblance to those works of human contrivance, which, along with a symmetry of parts, discover an adjustment of means to ends, and a tendency to self-preservation. If the actuating force cease after this operation, matter must remain for ever in disorder, and continue an immense chaos, without any proportion or activity. But suppose that the actuating force, whatever it be, still continues in matter, this first position will immediately give place to a second, which will likewise in all probability be as disorderly as the first, and so on through many successions of changes and revolutions. No particular order or position ever continues a moment unaltered. The original force, still remaining in activity, gives a perpetual restlessness to matter. Every possible situation is produced, and instantly destroyed. If a glimpse or dawn of order appears for a moment, it is instantly hurried away, and confounded, by that never-ceasing force which actuates every part of matter.

Thus the universe goes on for many ages in a continued succession of chaos and disorder. But is it not possible that it may settle at last, so as not to lose its motion and active force (for that we have supposed inherent in it), yet so as to preserve an uniformity of appearance, amidst the continual motion and fluctuation of its parts? This we find to be the case with the universe at present. Every individual is perpetually changing, and every part of every individual; and yet the whole remains, in appearance, the same. May we not hope for such a position, or rather be assured of it, from the eternal revolutions of unguided matter; and may not this account for all the appearing wisdom and contrivance which is in the universe? Let us contemplate the subject a little, and we shall find, that this adjustment, if attained by matter of a seeming stability in the forms, with a real and perpetual revolution or motion of parts, affords a plausible, if not a true solution of the difficulty.

It is in vain, therefore, to insist upon the uses of the parts in animals or vegetables, and their curious adjustment to each other. I would fain know, how an animal could subsist, unless its parts were so adjusted? Do we not find, that it immediately perishes whenever this adjustment ceases, and that its matter corrupting tries some new form? It happens indeed, that the parts of the world are so well adjusted, that some regular form immediately lays claim to this corrupted matter: and if it were not so, could the world subsist? Must it not dissolve as well as the animal, and pass through new positions and situations, till in great, but finite succession, it falls at last into the present or some such order?

Although extremely general, Hume is suggesting both a history and a mechanism. Hume posits conservation of motion or other similar laws of nature, presumably mathematical, and describes what will happen when you apply such laws to a world. Most situations are unstable, and precisely because they are unstable, they will not last, and other situations will come to be. But some situations are stable, and when such situations occur, they will last.

The need for conservation of motion or similar natural laws is not accidental here. This is why I included the first paragraph above, rather than beginning the quotation where Hume begins to describe his “new hypothesis of cosmogony.” Without motion, the situation could not change, so a new situation could not come to be, and the very ideas of stable and unstable situations would not make sense. Likewise, if motion existed but did not follow any law, all situations should be unstable, so no amount of change could lead to a stable situation. Thus since things always fall downwards instead of in random directions, things stabilize near a center, while merely random motion could not be expected to have this effect. Thus a critic might argue that Hume seems to be positing randomness as the origin of things, but is cheating, so to speak, by positing original stabilities like natural laws, which are not random at all. Whatever might be said of this, it is an important point, and I will be returning to it later.

Since his description is more general than a description of living things in particular, Hume does not mention anything like the theory of the common descent of living things. But there is no huge gulf here: this would simply be a particular application. In fact, some people have suggested that Hume may have had textual influence on Darwin.

While there are other anticipations (there is one in Immanuel Kant that I am not currently inclined to seek out), I will skip to Philip Gosse, who published two years before Darwin. As described in the linked post, while Gosse denies the historicity of evolution in a temporal sense, he posits that the geological evidence was deliberately constructed (by God) to be evidence of common descent.

What was Darwin’s own role, then, if all the elements of his theory were known to various people years, centuries, or even millennia in advance? If we look at this in terms of Thomas Kuhn’s account of scientific progress, it is not so much that Darwin invented new ideas, as that he brought the evidence and arguments together in such a way as to produce — extremely quickly after the publication of his work — a newly formed consensus on those ideas.

Common Sense

I have tended to emphasize common sense as a basic source in attempting to philosophize or otherwise understand reality. Let me explain what I mean by the idea of common sense.

The basic idea is that something is common sense when everyone agrees that something is true. If we start with this vague account, something will be more definitively common sense to the degree that it is truer that everyone agrees, and likewise to the degree that it is truer that everyone agrees.

If we consider anything that one might think of as a philosophical view, we will find at least a few people who disagree, at least verbally, with the claim. But we may be able to find some that virtually everyone agrees with. These pertain more to common sense than things that fewer people agree with. Likewise, if we consider everyday claims rather than philosophical ones, we will probably be able to find things that everyone agrees with apart from some very localized contexts. These pertain even more to common sense. Likewise, if everyone has always agreed with something both in the past and present, that pertains more to common sense than something that everyone agrees with in the present, but where some have disagreed in the past.

It will be truer that everyone agrees in various ways: if everyone is very certain of something, that pertains more to common sense than something people are less certain about. If some people express disagreement with a view, but everyone’s revealed preferences or beliefs indicate agreement, that can be said to pertain to common sense to some degree, but not so much as where verbal affirmations and revealed preferences and beliefs are aligned.

Naturally, all of this is a question of vague boundaries: opinions are more or less a matter of common sense. We cannot sort them into two clear categories of “common sense” and “not common sense.” Nonetheless, we would want to base our arguments, as much as possible, on things that are more squarely matters of common sense.

We can raise two questions about this. First, is it even possible? Second, why do it?

One might object that the proposal is impossible. For no one can really reason except from their own opinions. Otherwise, one might be formulating a chain of argument, but it is not one’s own argument or one’s own conclusion. But this objection is easily answered. In the first place, if everyone agrees on something, you probably agree yourself, and so reasoning from common sense will still be reasoning from your own opinions. Second, if you don’t personally agree, since belief is voluntary, you are capable of agreeing if you choose, and you probably should, for reasons which will be explained in answering the second question.

Nonetheless, the objection is a reasonable place to point out one additional qualification. “Everyone agrees with this” is itself a personal point of view that someone holds, and no one is infallible even with respect to this. So you might think that everyone agrees, while in fact they do not. But this simply means that you have no choice but to do the best you can in determining what is or what is not common sense. Of course you can be mistaken about this, as you can about anything.

Why argue from common sense? I will make two points, a practical one and a theoretical one. The practical point is that if your arguments are public, as for example this blog, rather than written down in a private journal, then you presumably want people to read them and to gain from them in some way. The more you begin from common sense, the more profitable your thoughts will be in this respect. More people will be able to gain from your thoughts and arguments if more people agree with the starting points.

There is also a theoretical point. Consider the statement, “The truth of a statement never makes a person more likely to utter it.” If this statement were true, no one could ever utter it on account of its truth, but only for other reasons. So it is not something that a seeker of truth would ever say. On the other hand, there can be no doubt that the falsehood of some statements, on some occasions, makes those statements more likely to be affirmed by some people. Nonetheless, the nature of language demands that people have an overall tendency, most of the time and in most situations, to speak the truth. We would not be able to learn the meaning of a word without it being applied accurately, most of the time, to the thing that it means. In fact, if everyone was always uttering falsehoods, we would simply learn that “is” means “is not,” and that “is not,” means “is,” and the supposed falsehoods would not be false in the language that we would acquire.

It follows that greater agreement that something is true, other things being equal, implies that the thing is more likely to be actually true. Stones have a tendency to fall down: so if we find a great collection of stones, the collection is more likely to be down at the bottom of a cliff rather than perched precisely on the tip of a mountain. Likewise, people have a tendency to utter the truth, so a great collection of agreement suggests something true rather than something false.

Of course, this argument depends on “other things being equal,” which is not always the case. It is possible that most people agree on something, but you are reasonably convinced that they are mistaken, for other reasons. But if this is the case, your arguments should depend on things that they would agree with even more strongly than they agree with the opposite of your conclusion. In other words, it should be based on things which pertain even more to common sense. Suppose it does not: ultimately the very starting point of your argument is something that everyone else agrees is false. This will probably be an evident insanity from the beginning, but let us suppose that you find it reasonable. In this case, Robin Hanson’s result discussed here implies that you must be convinced that you were created in very special circumstances which would guarantee that you would be right, even though no one else was created in these circumstances. There is of course no basis for such a conviction. And our ability to modify our priors, discussed there, implies that the reasonable behavior is to choose to agree with the priors of common sense, if we find our natural priors departing from them, except in cases where the disagreement is caused by agreement with even stronger priors of common sense. Thus for example in this post I gave reasons for disagreeing with our natural prior on the question, “Is this person lying or otherwise deceived?” in some cases. But this was based on mathematical arguments that are even more convincing than that natural prior.

Generalized Kantian Dichotomy

At the end of the last post I suggested that the confusion between the mode of knowledge and the mode of being might be a primary, or rather the primary, cause of philosophical error, with the exception of motivated error.

If we consider the “Kantian” and “anti-Kantian” errors in the last post, we can give a somewhat general account of how this happens. The two errors might appear to be mutually exclusive and exhaustive, but in fact they constitute a false dichotomy. Consider the structure of the disagreement:

A. Common sense takes note of something: in this case, that it is possible to know things. Knowledge is real.

B. The Kantian points out that the mode of knowing and the mode of being are not the same, and concludes that common sense is wrong. Knowledge is apparent, but not real.

C. The anti-Kantian, determined to uphold common sense, applies modus tollens. We know that knowledge is real: so the mode of knowing and the mode of being must be the same.

Each party to the dispute says something true (that knowledge is real, that the mode of being and the mode of knowing are not the same), and something false (that knowledge is not real, that the mode of being and the mode of knowing are the same.)

A vast number of philosophical disputes can be analyzed in a very similar manner. Thus we have the general structure:

A. Common sense points out that some item X is real.

B. The Kantian points out that the mode of knowing and the mode of being are not the same, and concludes that common sense is wrong. X is apparent, but not real.

C. The anti-Kantian, determined to uphold common sense, applies modus tollens. We know that X is real: so the mode of knowing and the mode of being must be the same.

Once again, in this general structure, each party to the dispute would say something true (that X is real, that the mode of knowing and being are not the same), and something false (the denial of one of these two.) As an example, we can apply this structure to our discussion of reductionism and anti-reductionism. The reductionist, in this case, is the Kantian (in our present structure), and the anti-reductionist the anti-Kantian. The very same person might well argue both sides about different things: thus Sean Carroll might be anti-reductionist about fundamental particles and reductionist about humans, while Alexander Pruss is anti-reductionist about humans and reductionist about artifacts. But whether we are discussing fundamental particles, humans, or artifacts, both sides are wrong. Both say something true, but also something false.

Several cautionary notes are needed in this regard.

First, both sides will frequently realize that they are saying something strongly counter-intuitive, and attempt to remedy this by saying something along the lines of “I don’t mean to say the thing that is false.” But that is not the point. I do not say that you intend to say the thing that is false. I say that you give an account which logically implies the thing that is false, and that the only way you can avoid this implication is by rejecting the false dichotomy completely, namely by accepting both the reality of X, and the distinction of the modes of knowing and being. Thus for example Sean Carroll’s does not distinguish his poetic naturalism from eliminativism in terms of what it says to be true, but only in terms of what it says to be useful. But eliminativism says that it is false that there are ships: therefore Carroll’s poetic naturalism also says that it is false that there are ships, whether he intends to say this or not, and whether or not he finds it useful to say that there are.

Second, this outline uses the terminology of “Kantian” and “anti-Kantian,” but in fact the two tend to blur into one another, because the mistakes are very similar: both imply that the unknown and the known, as such, are the same. Thus for example in my post on reductionism I said that there was a Kantian error in the anti-reductionist position: but in the present schema, the error is anti-Kantian. In part, this happened because I did not make these distinctions clearly enough myself in the earlier post. But is it also because the errors themselves uphold very similar contradictions. Thus the anti-reductionist thinks somewhat along these lines:

We know that a human being is one thing. We know it as a unity, and therefore it has a mode of being as a unity. But whenever anyone tries to explain the idea of a human being, they end up saying many things about it. So our explanation of a human being cannot be the true explanation. Since the mode of knowing and the mode of being must be the same, a true explanation of a human being would have to be absolutely one. We have no explanation like that, so it must be that a human being has an essence which is currently hidden from us.

Note that this reasons in an anti-Kantian manner (the mode of being and the mode of knowing must be the same), but the conclusion is effectively Kantian: possible or not, we actually have no knowledge of human beings as they are.

As I said in the post on reductionism, the parties to the dispute will in general say that an account like mine is anti-realist: realism, according to both sides, requires that one accept one side of the dichotomy and reject the other. But I respond that the very dispute between realism and anti-realism can be itself an example of the false dichotomy, as the dispute is often understood. Thus:

A. Common sense notes that the things we normally think and talk about are real, and that the things we normally say about them are true.

B. The Kantian (the anti-realist) points out that the mode of knowing and the mode of being are not the same, and concludes that common sense is wrong. The things we normally talk about appear to be real, but they are not.

C. The anti-Kantian (the realist) applies modus tollens. We know these things are real: so the mode of knowledge and the mode of being must be the same after all.

As usual, both say something true, and both say something false. Consider Scott Sumner, who tends to take an anti-realist position, as for example here:

Even worse, I propose doing so for “postmodern” reasons. I will start by denying the reality of inflation, and then argue for some substitute concepts that are far more useful. First a bit of philosophy. There is a lively debate about whether there is a meaningful distinction between our perception of reality, and actual reality. I had a long debate with a philosopher about whether Newton’s laws of motion were a part of reality, or merely a human construct. I took the latter view, arguing that if humans had never existed then Newton’s laws would have never existed. He argued they are objectively true. I responded that Einstein showed that were false. He responded that they were objectively true in the limiting case. I argued that even that might be changed by future developments in our understanding of reality at the quantum level. He argued that they’d still be objectively approximately true, etc, etc.

On the one hand, a lot of what Scott says here is right. On the other hand, he mistakenly believes that it follows that common sense is mistaken in matters in which it is not, in fact, mistaken. The reasoning is basically the reasoning of the Kantian: one notices that we have a specific mode of knowing which is not the mode of being of things, and concludes that knowledge is impossible, or in Scott’s terminology, “objective truth” does not exist, at least as distinct from personal opinion. He has a more extensive discussion of this here:

I don’t see it as relativism at all. I don’t see it as the world of fuzzy post-modern philosophers attacking the virtuous hard sciences. It’s important not to get confused by semantics, and focus on what’s really at stake. In my view, Rorty’s views are most easily seen by considering his denial of the distinction between objective truth and subjective belief. In order to see why he did this, consider Rorty’s claim that, “That which has no practical implications, has no theoretical implications.” Suppose Rorty’s right, and it’s all just belief that we hold with more or less confidence. What then? In contrast, suppose the distinction between subjective belief and objective fact is true. What then? What are the practical implications of each philosophical view? I believe the most useful way of thinking about this is to view all beliefs as subjective, albeit held with more or less confidence.

Let’s suppose it were true that we could divide up statements about the world into two categories, subjective beliefs and objective facts. Now let’s write down all our statements about the world onto slips of paper. Every single one of them, there must be trillions (even if we ignore the field of math, where an infinite number of statements could be constructed.) Now let’s divide these statements up into two big piles, one set is subjective beliefs, and the other pile contains statements that are objective facts. We build a vast Borgesian library, and put all the subjective beliefs (i.e. Trump is an idiot) into one wing, and all the objective facts (Paris is the capital of France) into the other wing.

Now here’s the question for pragmatists like Rorty and me. Is this a useful distinction to make? If it is useful, how is it useful? Here’s the only useful thing I can imagine resulting from this distinction. If we have a category of objective facts, then we can save time by not questioning these facts as new information arises. They are “off limits”. Since they are objective facts, they can never be refuted. If they could be refuted, then they’d be subjective beliefs, not objective facts.

But I don’t want to do that. I don’t want to consider any beliefs to be completely off limits—not at all open to refutation. That reminds me too much of fundamentalist religion. On the other hand, I do want to distinguish between different kinds of beliefs, in a way that I think is more pragmatic than the subjective/objective distinction. Rather I’d like to assign probability values to each belief, which represent my confidence as to whether or not the belief is true. Then I’d like to devote more of my time to entertaining critiques of highly questionable hypotheses, than I do to less plausible hypotheses.

Again, this makes a great deal of sense. The problem is that Scott thinks that either there is no distinction between the subjective and objective, or we need to be able to make that distinction subjectively. Since the latter seems an evident contradiction, he concludes that there is no distinction between subjective and objective. Later in the post, he puts this in terms of “map and territory”:

The other point of confusion I see is people conflating “the map and the territory”. Then they want to view “objective facts” as aspects of the territory, the underlying reality, not (just) beliefs about the territory. I don’t think that’s very useful, as it seems to me that statements about the world are always models of the world, not the world itself. Again, if it were not true, then theories could never be revised over time. After all, Einstein didn’t revise reality in 1905; he revised our understanding of reality–our model of reality.

“Statements about the world are always models of the world, not the world itself.” Indeed. That is because they are statements, not the things the statements are about. This is correctly to notice that the mode of knowledge is not the mode of being. But it does not follow that there are no objective facts, nor that objective facts are not distinct from opinions. Consider the statement that “dogs are animals.” We can call that statement a “model of the world.” But is not about a model of the world: it is about dogs, which are not our model or even parts of our model, but things moving around outside in the real world. Obviously, we cannot concretely distinguish between “things we think are true” and “things that are actually true,” because it will always be us talking about things that are actually true, but we can make and understand that distinction in the abstract. Scott is right, however, to reject the idea that some ideas are subjective “because they are about the map,” with other statements being objective “because they are about the territory.” In the map / territory terminology, all statements are maps, and all of them are about the territory (including statements about maps, which refer to maps as things that exist, and thus as part of the territory.)

We can see here how Scott Sumner is falling into the Kantian error. But what about the realist position? It does not follow from any of the above that the realist must make any corresponding error. And indeed, in all such dichotomies, there will be a side which is more right than the other: namely, the side that says that common sense is right. And so it is possible, and correct, to say that common sense is right without also accepting the corresponding falsehood (namely that the mode of knowing and the mode of being are the same.) But if we do accept the realist position together with the corresponding falsehood, this can manifest itself in various ways. For example, one might say that one should indeed put some things in the category of “off limits” for discussion: since they are objective facts, they can never be revised. Thus for example James Larson, as in an earlier discussion, tends to identify the rejection of his positions with the rejection of realism. In effect, “My beliefs are objectively true. So people who disagree with my beliefs reject objective truth. And I cannot admit that my beliefs might be false, because that would mean an objective truth could be false at the same time, which is a contradiction.” The problem will not always be manifested in the same way, however, because as we said in the last post, each end of the false dichotomy implies a similar contradiction and cannot be reasoned about coherently.

This or Nothing

In his homily on June 9th, Pope Francis spoke against excessively rigid views:

This (is the) healthy realism of the Catholic Church: the Church never teaches us ‘or this or that.’ That is not Catholic. The Church says to us: ‘this and that.’ ‘Strive for perfectionism: reconcile with your brother. Do not insult him. Love him. And if there is a problem, at the very least settle your differences so that war doesn’t break out.’ This (is) the healthy realism of Catholicism. It is not Catholic (to say) ‘or this or nothing:’ This is not Catholic, this is heretical. Jesus always knows how to accompany us, he gives us the ideal, he accompanies us towards the ideal, He frees us from the chains of the laws’ rigidity and tells us: ‘But do that up to the point that you are capable.’ And he understands us very well. He is our Lord and this is what he teaches us.

“Or this or that” and “Or this or nothing” are probably excessively literal translations of the Italian, which would actually mean “either this or that,” and “either this or nothing.”

It is a bit odd to speak of such views as “heretical,” since it would be hard to find a determinate doctrine here that might be true or false. Rather, the Pope speaks of an attitude, and is condemning it as a bad attitude, not only morally, but as leading one into error intellectually as well. We have seen various people with views and attitudes that would likely fit under this categorization: thus for example Fr. Brian Harrison maintains that a person cannot accept both Christianity and evolutionJames Larson maintains that disagreement with his theological and philosophical positions amounts to a “war against being,” thus asserting “either this or nothing” in a pretty immediate sense. Alexander Pruss maintains that either there was a particular objective moment when Queen Elizabeth passed from not being old to being old, or logic is false. We have seen a number of other examples.

The attitude is fairly common among Catholic traditionalists (of which Fr. Brian Harrison and James Larson are in fact examples.) Thus it is not surprising that the blog Rorate Caeli, engaging in exactly the “this or nothing” attitude that Pope Francis condemns, condemns Pope Francis’s statements as heretical:

(1) Either John Paul II and all the Popes who came before him are right, by emphasizing the “absoluteness” of the Church’s moral law and by classifying as a “very serious error” that the doctrine of the Church is only an “ideal”…

…or (2) Francis is right, by qualifying as “heretical” a rejection of the “Doctrine of the Ideal” as well as any affirmation of the absoluteness of moral prohibitions (‘or this or nothing’).

Regardless of the accusations of heresy on either side, however, Pope Francis is basically right in rejecting the attitude in question. I have spoken elsewhere about the fact that in discussion, one should try to look for what is true in the other person’s position. The most basic reason for this, of course, is that there is almost always some truth there. The attitude of “this or nothing” is basically a refusal to consider the truth in the other person’s position.

Strangely, as we will see in future posts, this turns out to be relevant to our discussion of elements.

[On another matter, a public service announcement: If you occasionally use a taxi, or might occasionally do so in the future, and you are not signed up with Uber, you should do so. Call a traditional taxi, and they will tell you they will be there in 20 – 30 minutes. They will actually be there in 45 – 60 minutes, and possibly not at all. With Uber, all it takes is a few clicks, and you will have a ride in 5 -10 minutes.

Let’s Draw a Line

James Larson, in the note currently at the beginning of his website, accuses Pope Francis of heresy:

Note (April 16, 2016): In order to add clarity as to the nature of the explicit heresy taught in Amoris Laetitia, I have added one paragraph approximately 2/3 of the way through the article below. It reads:

Herein resides the essence of this heresy. It lies specifically in teaching that there is a “gradualness” applicable to the possession of charity and sanctifying grace. It is Catholic dogma that possession of supernatural charity is an ontological state created by sanctifying grace added to the soul, that one cannot possess this charity unless living in this substantial state, and that it is this state of being which is absolutely necessary for receiving the Eucharist and other sacraments. It cannot be possessed by a person living in objective mortal sin, or by any person who is in some process of pastoral effort working towards the attainment of some “ideal”.

Larson is saying that sanctifying grace is a binary state, that it cannot be possessed by someone “living in objective mortal sin,” that these items are Catholic dogmas, and that Pope Francis contradicts them. The text in which he supposedly does this is paragraph 305 of Amoris Laetitia:

Because of forms of conditioning and mitigating factors, it is possible that in an objective situation of sin – which may not be subjectively culpable, or fully such – a person can be living in God’s grace, can love and can also grow in the life of grace and charity, while receiving the Church’s help to this end.

Larson is mistaken on almost every point. It is true that sanctifying grace would normally be considered a binary condition, where either you have it or you do not. But the Catholic Church does not typically create doctrines concerning deep matters of ontology. If someone were to assert that some people are in a vague condition where it is unclear whether or not they are in a state of grace, just as it is unclear whether some people are actually bald or just almost bald, this would not be a heresy. Nowhere does the Church condemn such a view.

But this is beside the point. It is entirely obvious that Pope Francis makes no such assertion in the text under consideration. Nor does he assert this, or anything like it, anywhere else in Amoris Laetitia.

“Living in objective mortal sin” refers to the “objective situation of sin” in the text of Pope Francis, and refers to the general idea of living a life where one regularly performs acts which the Church considers to be objectively grave sins. Larson asserts that the Church teaches that such a person cannot be in a state of grace.

This too is mistaken. The Catechism of the Catholic Church states:

1857 For a sin to be mortal, three conditions must together be met: “Mortal sin is sin whose object is grave matter and which is also committed with full knowledge and deliberate consent.”

1858 Grave matter is specified by the Ten Commandments, corresponding to the answer of Jesus to the rich young man: “Do not kill, Do not commit adultery, Do not steal, Do not bear false witness, Do not defraud, Honor your father and your mother.” The gravity of sins is more or less great: murder is graver than theft. One must also take into account who is wronged: violence against parents is in itself graver than violence against a stranger.

1859 Mortal sin requires full knowledge and complete consent. It presupposes knowledge of the sinful character of the act, of its opposition to God’s law. It also implies a consent sufficiently deliberate to be a personal choice. Feigned ignorance and hardness of heart do not diminish, but rather increase, the voluntary character of a sin.

1860 Unintentional ignorance can diminish or even remove the imputability of a grave offense. But no one is deemed to be ignorant of the principles of the moral law, which are written in the conscience of every man. The promptings of feelings and passions can also diminish the voluntary and free character of the offense, as can external pressures or pathological disorders. Sin committed through malice, by deliberate choice of evil, is the gravest.

The Catechism is clear that doing something objectively wrong is not enough for a sin to be mortal, or to exclude someone from the state of grace. In order for this to happen, there also needs to be “full knowledge” and “complete consent.”

The text does not explicitly address the kind of “objective situation of sin” that Pope Francis and James Larson discuss. Much less, therefore, does it assert that a person in such a situation cannot be in a state of grace. However, it is not difficult to see from the above text that a person could be in such a situation without mortal sin. One of the factors that can “diminish the voluntary and free character of the offense” is “external pressures.” The situations under discussion are precisely situations where there are external pressures. That is why they are considered “situations” as opposed to an arbitrarily repeated series of actions. Since the consent must be “complete” and since it can be diminished by these pressures, a person might very well fail to sin mortally in such a situation, even if the situation lasts for a long time.

We can see that Larson’s positions do not correspond very well with anything that the Church actually teaches. Why then does he make these assertions?

I suggest that we have here a case of highly motivated thinking. Larson wants to believe that sanctifying grace is a binary condition, he wants to believe that a divorced and remarried person could not be in that condition, he wants to believe that these are teachings of the Church, and he wants to believe that Pope Francis contradicts these things.

Why would someone have such desires? Larson says in article 25:

Since Pope Francis’ recent interviews and his letter to the editor of La Civilta Cattolica, I have received emails from traditional Catholics which speak of a new level of despair. It is as though they are desperately seeking some explanation of what is happening with the Papacy and the Church which will allow them to escape from coming to some dreadful conclusion.

The situation reminds me of a passage from Robert Bolt’s A Man For All Seasons. In the face of all the forces of evil moving in to ensnare and destroy him, Sir Thomas More offers the following impassioned words to his beloved daughter:

“Listen, Meg, God made the angels to show Him splendor, as He made animals for innocence and plants for their simplicity. But Man He made to serve Him wittily, in the tangle of his mind. If He suffers us to come to such a case that there is no escaping, then we may stand to our tackle as best we can, and, yes, Meg, then we can clamor like champions, if we have the spittle for it. But it’s God’s part, not our own, to bring ourselves to such a pass. Our natural business lies in escaping. If I can take the oath, I will.”

It seems evident that the “tangle of the mind” from which traditional Catholics are now desperately trying to escape is the apparent overwhelming evidence that their Church is being destroyed from within. They dread that they are being irresistibly backed into a corner where they will be forced to conclude that the Church, in what they always considered to be her inviolable nature (if she is to be considered real at all) has contradicted this nature, and has therefore been proved to be a human invention, and not the work of God. In other words, they fear the loss of their faith.

I think this is a correct description of how many people feel. I think it is also a correct description of the way Larson himself feels, and I think it can explain why he desires to hold the above opinions concerning Pope Francis and Amoris Laetitia. This might seem a bit paradoxical. He accuses Pope Francis of heresy. Would not this be a very good example of the kind of thing he should be hoping to avoid?

Yes, in one way, but in another way it is an advantage to him if Pope Francis explicitly falls into heresy. This is important to him. In the first quoted passage, he mentions the “nature of the explicit heresy” taught by Pope Francis. It is not only heresy, but “explicit heresy.”

When people change their minds, they often do so gradually, and by degrees, and in such a way that sometimes they do not even notice that they have changed their minds. It follows that if someone does not want to change their mind, they have a reason to be cautious about gradual changes of opinion. Such changes not only could lead to what they do not want, namely changing their mind, but they could lead to this without the person even noticing it has happened.

Another point should be made about this. I pointed out here that despite the fact that it would be unreasonable to say that getting one year older makes you pass from “not being old” to “being old”, this does not prevent you from growing up. In the same way, if someone changes his mind gradually, at each point he may be able to say, “this change is too small to constitute a passage from not having changed my mind to having changed my mind.” He may be quite right. But this will not prevent it from being true at the end that he has changed his mind in comparison with his original position.

And just as individual human beings change their minds, so the Church changes its mind, gradually and by degrees, and sometimes without saying that a change has occurred. So just as someone who wishes to avoid changing his mind should be cautious about gradual changes, so someone who does not want the Church to change its mind will wish it to be cautious about gradual changes. This is what is happening here with Larson’s argument. It is an advantage to him if Amoris Laetita is explicitly heretical, because in that case it can be completely rejected, preventing the process of gradual change. If the document is not heretical (and it is not) it will be bound to cause gradual changes of various kinds, and there is no way to predict the end results in advance.

In a certain way, traditionalist Catholics are often more reasonable in this regard than others who would be considered “conservative” rather than traditionalist. Thus for example Jimmy Akin says:

11. Does the document foresee any possibility for sacramentally absolving and giving Communion to people who are civilly remarried if they are not living as brother and sister?

It does. In the main text of the document, it begins by noting certain principles to be taken into account, stating:

For an adequate understanding of the possibility and need of special discernment in certain “irregular” situations, one thing must always be taken into account, lest anyone think that the demands of the gospel are in any way being compromised.

The Church possesses a solid body of reflection concerning mitigating factors and situations.

Hence it can no longer simply be said that all those in any “irregular” situation are living in a state of mortal sin and are deprived of sanctifying grace.

More is involved here than mere ignorance of the rule. A subject may know full well the rule, yet have great difficulty in understanding “its inherent values,” or be in a concrete situation which does not allow him or her to act differently and decide otherwise without further sin. . . .

The Catechism of the Catholic Church clearly mentions these factors: “imputability and responsibility for an action can be diminished or even nullified by ignorance, inadvertence, duress, fear, habit, inordinate attachments, and other psychological or social factors” (CCC 1735).

In another paragraph, the Catechism refers once again to circumstances which mitigate moral responsibility, and mentions at length “affective immaturity, force of acquired habit, conditions of anxiety or other psychological or social factors that lessen or even extenuate moral culpability” (CCC 2352).

For this reason, a negative judgment about an objective situation does not imply a judgment about the imputability or culpability of the person involved. (AL 301-302).

The document thus envisions the case of a person who may be living in an objectively sinful situation but who is not mortally culpable because of a variety of factors of a cognitive or psychological nature.

Nothing in this is new. The Church has long recognized that people living in objectively grave sin may not be in a state of mortal sin.

Akin is right that “the Church has long recognized that people living in objectively grave sin may not be in a state of mortal sin.” This was discussed above. But “nothing in this is new” is simply not true, if it is understood in relation to the question about communion for the divorced and remarried. The Pontifical Council for Legislative Texts stated in 2000:

Any interpretation of can. 915 that would set itself against the canon’s substantial content, as declared uninterruptedly by the Magisterium and by the discipline of the Church throughout the centuries, is clearly misleading. One cannot confuse respect for the wording of the law (cfr. can. 17) with the improper use of the very same wording as an instrument for relativizing the precepts or emptying them of their substance.

The phrase “and others who obstinately persist in manifest grave sin” is clear and must be understood in a manner that does not distort its sense so as to render the norm inapplicable. The three required conditions are:

a) grave sin, understood objectively, being that the minister of Communion would not be able to judge from subjective imputability;

b) obstinate persistence, which means the existence of an objective situation of sin that endures in time and which the will of the individual member of the faithful does not bring to an end, no other requirements (attitude of defiance, prior warning, etc.) being necessary to establish the fundamental gravity of the situation in the Church.

c) the manifest character of the situation of grave habitual sin.

The text is clear: people in the situation under discussion are not to be given communion, whether or not they are in the state of grace. It is true that they do not assert that such people are necessarily in a state of sin, as James Larson does, but the prohibition does not depend on their subjective condition. And thus when asked whether he intended to change anything, Pope Francis said that he did intend such a change:

Rocca: Thank you Holy Father. I see that the questions on immigration I had thought of have already been asked, and you have responded very well. So, if you will permit me to ask a question on another event of the last few days, which was your Apostolic Exhortation.

As you know well, there was much discussion on one of many points – I know we have concentrated a lot on it – but there has been much discussion after the publication…Some maintain that nothing has changed with respect to the discipline that governs the access to the Sacraments for the divorced and remarried, and that the law and the pastoral practice and obviously the doctrine remains the same; others maintain instead that much has changed and that there are many new openings and possibilities.

And the question for a person, a Catholic, that wants to know: Are there new concrete possibilities that did not exist before the publication of the Exhortation or not?

Pope Francis: I can say yes. Period. But that would be too small an answer.

Akin’s way of thinking goes, “This does not contradict the Church’s current teaching. So it’s nothing new.” Larson, far more reasonably, recognizes in practice (although probably not in principle) that “this does not contradict the Church’s current teaching” can be true at every point in time, without this preventing the Church from changing its teaching in the end. By asserting that Amoris Laetitia is heretical, he hopes to draw a line, in order to remove the possibility of gradual change ultimately resulting in substantial change.

James Chastek, talking about disagreement on philosophical topics, says:

We care too much about philosophical topics ever to agree about them, and we achieve widespread successful consensus on scientific matters because we care very little which theory turns out to be true. The beauty and utility of math and science are there for anyone to see, but it’s not as if any one would kill, die, be celibate, or riot over them. Math and science of themselves, cut off from any reference to the mytho-philosophical (like the praise or the defiance of the gods) are not the sort of thing that one would think to praise in epic poetry, polyphonic splendor à la a Gounod Mass, or even a pop song.

We have discussed much the same issue here, although we pointed out that caring too much is only one part of the cause of such disagreement. Something else can be seen in the case of Larson’s disagreement with Amoris Laetita. It is not merely that he cares about the position he holds. He cares about agreement and disagreement, directly. For the reasons stated, he wants to disagree with Pope Francis. Thus in order to be sure that he does, he needs to describe the Pope’s position in various ways.

This is not uncommon. People frequently care not only about their positions, but also about the fact that they agree with certain people, and that they disagree with others. People often draw lines exactly for this reason, namely in order to disagree with someone else.
