Sins of the physicalist literature

Back before I opened Dangerous Idea, I gave this response to physicalist critics of the AFR, on Bill Vallicella's blog.

 A lot of the physicalist literature is guilty of one or all of the following sins, which in my estimation are:
1) A dogmatic pre-commitment to materialism.
2) Changing the explanandum in order to make the physicalistic explanation possible.
3) Presuming the very ideas one is trying to explain naturalistically.
4) Issuing gigantic promissory notes to future science, when we have no idea how future science will go.

The Brain Fallacy

A redated post.

I've been revising a paper of mine that I did in England in response to Carrier, and I have added this section, on what I call the brain fallacy:

But more than that, here again we find Carrier explaining one kind of mental activity in terms of another mental activity and then explaining it “naturalistically” by saying “the brain” does it. My argument is, first and foremost, that something exists whose activities are to be fundamentally explained in intentional and teleological terms. In order for talk about the brain to play its proper role in a physicalistic (non-intentional and non-teleological in the final analysis) analysis of mental events, we have to be sure that we are describing a brain that is mechanistic and part of a causally closed physical world. What I wrote in response to Keith Parsons, who had said that we could take what in Philosophia Christi applies here as well: (Parsons had argued that we could simply take all the characteristics that I wanted to attribute to the non-physical mind and attribute them to the brain).

But we should be careful of exactly what is meant by the term “brain.” The “brain” is supposed to be “physical,” and we also have to be careful about what we mean by “physical.” If by physical we mean that it occupies space, then there is nothing in my argument that suggests that I need to deny this possibility. I would just prefer to cal the part of the brain that does not function mechanistically the soul, since, as I understand it, there is more packed into the notion of the physical than just the occupation of space. If on the other hand, for something to be physical (hence part of the brain) it has to function mechanistically, that is, intentional an teleological considerations cannot be basic explanations for the activity of the brain, then Parsons’ suggestion (and Carrier’s as well-VR) is incoherent.

I think that a many people fail to see the difficulties posed by the arguments from reason because they think they can just engage in some brain-talk (well, the brain does this, the brain does that, etc.) and call that good. I call that the brain fallacy. The question should always be, “If we view the brain as a mechanistic system in the full sense, does it make sense to attribute this characteristic to the brain?” Using brain-talk doesn’t mean that the work of physicalistic analysis has really been done.

II. C. S. Lewis’s argument, and mine

            In reading John Beversluis’s new edition of C. S. Lewis and the Search for Rational Religion, it occurred to me that while I have developed Lewis’s argument a great deal, I have not been as explicit as I might have been in delineating exactly how my argument differs from, and develops his. Of course, Lewis didn’t invent the argument, and it has an important predecessor in Arthur Balfour, the Prime Minister-philosopher of the late 19^th and early 20^th centuries. Lewis’s role was to introduce the argument to a popular audience, and to revise the argument in response to the criticisms of Elizabeth Anscombe.  There have been other important contributors to the argument, in particular William Hasker and Alvin Plantinga.

            At several points along the way I have introduced some structure to the argument that was not originally present in Lewis. I am certainly following Lewis’s fundamental idea in this, but a number of the nuances in the argument are my own. Explicating exactly what I have done on this might be helpful in understanding my argument.      

Naturalism and Supernaturalism

Lewis begins his discussion by distinguishing between naturalism and supernaturalism. A naturalist is someone who thinks that the privilege of “being on its own,” belongs to “the whole show,” in much the way that sovereignty, in a democracy, belongs to the people not to some particular person or group of persons. A supernaturalist thinks that there are certain real things (or One Thing) that have the privilege of existing on their own, and that other objects depend on that for its existence. Further, he distinguished a “strict materialism,” which he thinks can be refuted by the one-line Haldane quote (If my mental processes are determined wholly by the motions of atoms in my brain, then I have no reason to suppose that my beliefs are true, and hence I have no reason for supposing that my brain is made up of atoms.), from naturalism that is not purely materialistic, and must be refuted with a more complex argument. Lewis says that if naturalism is true, there can be no free will, because determinism would be true. He mentions quantum mechanics, but he describes quantum-mechanical indeterminacy as a “threat” to naturalism, in which the “subnatural” can invade nature “from below,” as it were. However, he expresses doubt that this kind of indeterminism will continue to be affirmed by science.

            Because of this, Beversluis responds that his argument against naturalism works, if at all, against deterministic forms of naturalism, and unless the naturalism in question is of the determinist variety, Lewis’s argument is not an argument against that. But does determinism really make a difference? In deterministic forms of naturalism, events are guaranteed by the action of non-rational causes. In non-deterministic forms of naturalism, there is brute chance instead of determinism, but do events ever happen because of reasons? It doesn’t seem as if determinism makes a relevant difference.

            I think Lewis’s exposition of the naturalist-supernaturalist distinction needs some further development for philosophical argumentation today. I ask the question of whether the basic causes of the universe are mentalistic or non-mentalistic. If the basic causes of the universe are non-mentalistic, then if we have a mentalistic explanation, such as “Smith believes in evolution, in part, because the fossil record supports it,” then there has to be some explanation underlying that one which in non-mentalistic cause-and-effect operation of mindless atoms moving in accordance with the laws of nature is what is happening in the final analysis. On the other hand, if we look at those same atoms from the standpoint of theism, we find that those particles have the powers and liabilities they do because God created them that way. Scratch far enough, and you get a mentalistic explanation, not a non-mentalistic one. It is interesting that when you look at what makes something “material” or “natural,” you end up defining “material” in terms of the absence of mental characteristics. If a naturalistic worldview is true, then reason comes late to the party, when a brain of sufficient sophistication develops. Lewis describes his argument as an argument for supernaturalism, which is fine so long as we understand that by supernatural, what we mean is that it has, at bottom, and not a non-mentalistic explanation. Richard Carrier, perhaps the Argument from Reason’s most prolific critic, puts it this way.

Hence, I propose a general rule that covers all and thus distinguishes naturalism from supernaturalism: If naturalism is true, everything mental is caused by the nonmental, whereas if supernaturalism is true, at least one thing is not.

            But what are the characteristic of the mental? I have identified four characteristics of the mental. The first mark of the mental is purpose. For anyone who denies the ultimacy of the mind, an explanation in terms of purposes requires a further nonpurposive explanation to account for the purpose explanation. The second mark is intentionality or aboutness. Genuinely non-mental states are not about anything at all. The third mark is normativity. A normative explanation must be explained in terms of the non-normative, in the mental is not on the ground level of reality. The fourth mark is subjectivity.  There is no inner perspective at the physical level.

            Hence, a naturalistic view has, on my view, three basic elements. One of them is a mechanistic, that is non-mentalistic, basic level of reality. The second is the doctrine of the causal  closure of the physical. This does not require determinism, but what it does require that nothing outside of the physical be in causal connection. The third doctrine, is the doctrine of supervenience. Whatever is not itself physical must in fact, supervene on the physical. Therefore, this conception of reality is one which prohibits skyhooks, that is, anything from a higher level that is not accounted for on the lower level.

            Having laid out these elements, we can proceed to consider what I maintain a naturalistic view has difficulty accounting for. We could begin by looking at what human rationality is, or how it is supposed to manifest itself. Atheists very often perceive themselves has having the more rational view. The claim that, instead of believing things on faith, they look at the evidence and believe only what the evidence supports. But let’s take a look at how this works. If someone, let’s say, believes in evolution because they believe the fossil record supports it, that seems to imply that one set of mental events, those involved in examining and evaluating the fossil evidence, helps to bring about that fact that the person believes in evolution. But, it looks as if, at the basic level of analysis, mental states do not play any role qua mental states. What we have to be calling an instance of mental causation has to in fact be an example of physical causation in which the real causes are in the non-mental supervenience base, not amongst the mental states themselves.

            In fact, Lewis said that all knowledge, apart from the knowledge of our sensations, is inferred from those sensations. This led Beversluis to presume that his argument is essentially committed to the idea that, for example, our knowledge that there is a tree in the quad which I see, is really inferential knowledge. He points out that Lewis doesn’t really defend this view of sensory knowledge as inferential, and it would be odd for him to construct an argument based on this kind of view. But Lewis did not have to take such a strong view of inferential knowledge in order for his argument to work. What he needs, instead, is simply to argue that inferential knowledge is essential to science, since no modern atheist is going to argue that science does not acquire knowledge at all. If you consider the process of doing a mathematical equation, or basing a belief in evolution on the evidence, you will see that if your worldview says that this never happens, then this is certainly a very serious problem. These seem to be clear cases in which one mental event cause another mental event.

                C. S. Lewis’s Argument from Reason

            Lewis’s contribution to Christian apologetics is many and varied, but one of his contributions seems to be of great contemporary relevance, and that is his argument from reason. The argument from reason is only indirectly an argument for Christianity or even for theism, but is instead an argument against one of Christian theism’s most popular rivals, and that is a doctrine called metaphysical naturalism.  In recent years, we have seen a very aggressive version of this doctrine propounded by advocates of what is today called “The New Atheism.” Of course, the atheists we have always had with us, but led by popular writers such as Richard Dawkins, Christopher Hitchens, Sam Harris, and Daniel Dennett, atheists have made it their goal to eliminate religious belief in general, and Christianity in particular, from the face of the earth. At the same time, these atheists have made if very clear what they want to replace religious belief with. They want to people all over the world reject whatever religions they currently accept and embrace instead a doctrine of scientific naturalism. This effort has found its way onto sign on British buses that say “There is almost certainly no God. Now go on and enjoy your day.” To people like Dawkins, belief in the existence of God, or in Christianity, isn’t just false, it is delusional, which means it believed by its adherents in the teeth of overwhelming evidence that it is not true.  Further, they maintain that religious beliefs are not a benign delusion, it is a delusion that blocks the advancement of science at every turn, and actually leads its followers to resort to violence, as is evidenced by the 9/11 attacks on the Twin Towers, and George W. Bush’s decision to invade Iraq.

            One of the assumptions made by the New Atheists is that they suppose that religious believers believe as a matter of faith, which to them means that believers believe in spite of the evidence. I do not know what someone like Dawkins would make of Lewis’s famous statement from Mere Christianity, in which he says “I am not asking anyone to accept Christianity if his best reasoning tells him that the weight of evidence is against it. That is not the point at which faith comes in.” But they are quite convinced that the weight of the evidence is against religious belief, and that such faith does considerable harm.

            I noted earlier that the New Atheists not only want to make religious belief disappear, they want to replace it with a non-religious doctrine which is called philosophical naturalism. It is expressed in Carl Sagan’s famous pronouncement that “The Cosmos is all the was, or is, or ever will be.” But there is more to it than this. In the book entitled Darwin’s Dangerous Idea, (the book whose title I cannibalized in “C. S. Lewis’s Dangerous Idea) Daniel Dennett contrasts two types of explanations, one of which he calls cranes, and the other he calls skyhooks. Cranes are bottom-up explanations, which explain the more intelligent and more complex in terms of the less intelligent and less complex. Where you have a mental explanation, you must explain that mental explanation in terms of something that is non-mental. For example, if you say that the purpose of your eye is to see, that might be an acceptable thing to say, so long as you can cash that explanation out in terms of something that is not so purposive. In Darwinian biology, if you say that the purpose of your eye is to see, what that means is that the function and survival value of the eye is that it enables the one who has it to see. Evolution will select for something that gives its possessor a survival advantage, but will not do so as a matter of a deliberate mental process. If we say that God designed you eye so that you can see, that would be, on Dennett’s view, and unacceptable skyhook, which he describes as a mind-first explanation with no underlying non-mental explanation. However, the Darwinian version of this statement is acceptable, because even though there is a mental explanation on the surface of things, it is merely a stand-in for a proper scientific explanation that excludes the mental. The mental is, according to naturalism, a system by-product of an inherently non-mental universe. It is not literally true that the chicken crossed the road to get to the other side. The history of science, on this view, is the history of displacing mental explanations, at least at the basic level of analysis, with non-mental ones. Every day, in every way, we’re getting closer and close to the time when all the skyhooks are gone, and all we have are cranes.

            The argument from reason essentially says that this can’t be the comprehensive story of the universe.  Remember, atheists say that religious believers believe in spite of the presence of overwhelming evidence against what they believe. What that implies is that there is an alternative to this, namely, believing in accordance with, and because of the evidence. But if everything in the universe has to be explained from the bottom up, then can it be literally true to say “I reject belief in the existence of God because if there were a God, there would be evidence of his existence which we do not find?” In the final analysis, stuff moves not according to the laws of reasoning or logic, but according to the laws of physics, without intention or purpose. If this is so, then how is it possible to believe anything on the basis of evidence? Scientists believe what they do because they evaluate the evidence for scientific hypotheses, and accept the one which has the most evidential support. Thus, Darwin, we are told, found evidence for his theory of natural selection based on evidence taken from his observations of finches on the Galapagos Islands. Science would not exist if it were not possible to give mentalistic explanations for the activities of scientists. Hence, the ban on skyhooks has to stop when we start talking about the rational formation of beliefs, whether this is the formation of scientific beliefs based on evidence, or the mathematical underpinnings of the sciences (as both Lewis and I learned to our chagrin in school, you can’t get very far in the sciences without being good at math), or the rational consideration of the question of whether or not there is a God, or whether Christianity is true. If we explain reason in terms of the non-rational, we invariably end up explaining it away.

Defending Carrier Against Me

This is a response by Carrier admirer Ben Schuldt to an early response of mine to Carrier. He uses the fallacy of composition charge against my argument.

Physicalist analyses of mental start by defining the physical by excluding the mental, but then combinations of the physical are supposed to be mental. Yet, when the physical descriptions are complete, it looks as if the marks of the mental have disappeared and have been replaced by something that doesn't look mental at all. I call this changing the subject, but Schuldt thinks that I am question-beggingly insisting on a "magical" analysis of mind. I say I am insisting on a mentalistic analysis of mind. The mental is what it is, and is not something else.

It doesn't seem that all part-to-whole inferences commit the fallacy of composition. For example, if every part of the shed in the back yard is made of wood, then the shed is made of wood, isn't it? (Even if it doesn't weigh the same as a duck).

A Youtube Attack on my AFR

At least Richard Carrier read my book. I'm not sure this guy has.

For example, he makes the simplistic "argument from computers", which I responded to in my book, and numerous times subsequently, including here. 

I am not saying that there aren't more sophisticated ways of using computer science to critique the AFR, but this is not one of them.
