Brian Auten interviews Dr. Angus Menuge on philosophy of mind

Leave a comment

Click here for the interview. It’s up at Apologetics 315!

Details:

Today’s interview is with Dr. Angus Menuge, Professor of Philosophy  at Concordia University, and author of Agents Under Fire: Materialism and the Rationality of Science. He talks about his background and work, the philosophy of mind, what reason (or reasoning) is, what materialism is as a worldview, things excluded from a materialistic worldview, methodological naturalism and materialism, accounting for free will, materialistic accounts of reason, the epistemological argument from reason, the ontological argument from reason, finding the best explanation for reason, problems with methodological naturalism, implications of materialism, practical application of the argument from reason, advice for apologists, the International Academy of Apologetics, and more.

If what Dr. Menuge says in this interview is true, and I think it is, then a person who believes in materialism can neither ground free will nor rationality! So atheism wouldn’t really be freethought so much as it would be… un-free… non-thought.

In case people don’t want to listen to the podcast, then I’ve got some things for you to read below.

The ontological argument from reason

Dr. Menuge presented a paper at the real Evangelical Philosophical Society conference for students and professors of philosophy, and you can download the paper here in Word format. (here’s a PDF version I made)

Here is the introduction to the paper that Dr. Menuge read at the EPS conference:

The argument from reason is really a family of arguments to show that reasoning is incompatible with naturalism. Here, naturalism is understood as the idea that foundationally, there are only physical objects, properties and relations, and anything else reduces to, supervenes on, or emerges from that. For our purposes, one of the most important claims of naturalism is that all causation is passive, automatic, event causation (an earthquake automatically causes a tidal wave; the tidal wave responds passively): there are no agent causes, where something does not happen automatically but only because the agent exerts his active power by choosing to do it. The most famous version of the argument from reason is epistemological: if naturalism were true, we could not be justified in believing it. Today, I want to focus on the ontological argument from reason, which asserts that there cannot be reasoning in a naturalistic world, because reasoning requires libertarian free will, and this in turn requires a unified, enduring self with active power.

The two most promising ways out of this argument are: (1) Compatibilism—even in a deterministic, naturalistic world, humans are capable of free acts of reason if their minds are responsive to rational causes; (2) Libertarian Naturalism—a self with libertarian free will emerges from the brain. I argue that neither of these moves works, and so, unless someone has a better idea, the ontological argument from reason stands.

The paper is 11 pages long, and it is helpful for those of you looking for some good discussion of one of the issues in the area of philosophy of mind.

You may also be interested in Alvin Plantinga’s epistemological argument from reason, which is related to this argument. It shows that even to have the ability to think, you have to have a certain anthropology and you have to have mental faculties that are designed for reason, not survival.

Methodological naturalism

Dr. Menuge also wrote an article entitled “Is methodological materialism good for science?”.

Intro:

Should science by governed by methodological materialism? That is, should scientists assume that only undirected causes can figure in their theories and explanations? If the answer to these questions is yes, then there can be no such thing as teleological science or intelligent design. But is methodological materialism a defensible approach to science, or might it prevent scientists from discovering important truths about the natural world? In my contribution to The Waning of Materialism (Oxford University Press, 2010), edited by Robert Koons and George Bealer, I consider twelve of the most common arguments in favor of methodological materialism and show that none of them is convincing.

Of these arguments, perhaps the most prevalent is the “God of the gaps” charge, according to which invoking something other than a material cause is an argument from ignorance which, like a bad script writer, cites a deus ex machina to save our account from difficulty. Not only materialists, but also many Christian thinkers, like Francis Collins, worry that appeal to intelligent design commits the God of the gaps fallacy.

As I argue, however, not only is an inference to an intelligent cause not the same as an inference to the supernatural, it is a mistake to assume that all gap arguments are bad, or that only theists make them. If a gap argument is based solely on ignorance of what might explain some phenomenon, then indeed it is a bad argument. But there are many good gap arguments which are made both by scientific materialists and proponents of intelligent design.

So how do you make an argument like that?

As Stephen Meyer has argued in his Signature in the Cell, intelligent design argues in just the same way, claiming not merely that the material categories of chance and necessity (singly or in combination) are unable to explain the complex specified information in DNA, but also that in our experience, intelligent agents are the only known causes of such information. The argument is based on what we know about causal powers, not on what we do not know about them.

Since the inference is based on known causal powers, we learn that the cause is intelligent, but only further assumptions or data can tell us whether that intelligence is immanent in nature or supernatural. It is a serious mistake to confuse intelligent design with theistic science, and the argument that since some proponents of design believe that the designer is God, that is what they are claiming can be inferred from the data, is a sophomoric intensional fallacy.

If you think this is interesting, then do have a listen to the podcast. Dr. Menuge is not an ordinary academic – he is very direct. He calls materialism “a catastrophe” in the podcast! Not a shrinking violet.

Some arguments for substance dualism, and one objection

10 Comments

Philosophy of mind is not something I’ve studied very much, but I do know about the different views like physicalism, epiphenomenalism, property dualism and substance dualism. I also know some of the basic arguments for and against each view.

In this post, I just wanted to show people a little bit about how you argue for substance dualism, using philosophical and scientific arguments. I find this topic to be really really dry, and I can barely stay awake when J.P. Moreland talks about it in lectures. But I hope a little bit of exposure won’t put you all to sleep.

Philosophical arguments

Let’s start with this old paper by John Depoe.

He writes about the persistent identity argument:

Another argument supporting substance dualism is that one maintains personal identity through change. Even though one is continuously going through physical changes and experiencing different mental states, a person continues to be the same person. If persons were identical with their physical parts or mental states, they would cease to be the same persons as these changes occurred. Therefore, it is necessary to postulate an immaterial, substantial self that endures through change.

Suppose that someone believes that people do not maintain identity through change and concludes that the previous argument for substance dualism fails. This denial of personal identity through change, I contend, presents untenable difficulties. First, there is one’s own awareness of being the same person through change. Moreover, if one is not literally the same person through these changes, how can a person maintain long-term goals and desires?

If you are your body, and your body is always changing, then you aren’t the same person now as 5 minutes ago.

There are more arguments for substance dualism here, from J.P. Moreland.

Experimental evidence

Doug Groothuis talks about some experimental evidence in this paper.

Excerpt:

Dr. Wilder Penfield was known for his ground-breaking work with epilepsy. His work involved stimulating brain tissue in conscious patients in order to find the causes of epilepsy. During these sessions Penfield found that the prodding of certain areas of the brain triggered vivid memories of past events. The patients reported remembering clearly such things as the taste of coffee. One patient, while on an operating table in Montreal, Canada, remembered laughing with cousins on a farm in South Africa. What amazed Penfield was that his patients, who were not under anesthetic, were simultaneously conscious of the re-experienced memories and of being prodded by an electrode in an operating room. Penfield called this a “double consciousness” wherein a memory was stimulated physically but was attended to and recognized as a memory by a conscious patient. Penfield likened this to the patient watching a television program while remaining aware that it wasn’t now happening.

Penfield repeated these results on hundreds of epileptic patients and concluded that a separable mind was able to track what the brain was doing as a result of the artificial stimulation. One’s mind in a sense could transcend the operations of the brain, monitoring memories without actually placing oneself in the situation remembered. Penfield noted that “The mind of the patient was as independent of the reflex action as was the mind of the surgeon who listened and strove to understand. Thus, my argument favours independence of mind-action.” Penfield also stated that if we liken the brain to a computer, it is not that we are a computer, but that we have a computer.

Penfield, who began his research as a materialist, switched to dualism after extensive research with epileptic patients. He said, “Something else finds its dwelling place between the sensory complex and the motor mechanism. . . . There is a switchboard operator as well as a switchboard.”

Although nonepileptic patients do not respond similarly to brain stimulation, other researchers, such as Sir John Eccles, a neurobiologist, have similarly concluded that the brain alone cannot account for a many phenomena. Eccles’ hypothesis is that the self-conscious mind is an independent entity that is actively engaged in reading from the multitude of active centres in the modules of the liaison areas of the dominant cerebral hemisphere. The self-conscious mind selects from these centres in accord with its attention and its interests and integrates its selection to give unity of conscious experience from moment to moment.

Thus, Eccles’ conclusions agree with Penfield’s, and his areas of research extend farther than that of epileptic patients. Eccles deems the “monist materialist” hope for an eventual physical explanation for mental events as wrongheaded in principle because mental events are not “simply derivative of aspects of nerve endings. There is no evidence for this whatever.” Further, Eccles argues that his “strong dualist-interactionist hypothesis . . . has the recommendation of its great explanatory power. It gives in principle at least explanations of the whole range of problems relating to brain-mind interaction.”Eccles notes that it has been impossible to develop a materialist explanation of “how a diversity of brain events come to be synthesized so that there is a unified conscious experience of a global or gestalt character.” Given this impasse, Eccles proposed that “the self-conscious mind” serve to integrate the apparently disparate brain processes into a unified consciousness.

I think that Alvin Plantinga, Keith Yandell, J.P. Moreland, William Lane Craig, Stephen Davis, John Depoe, Douglas Groothuis and Charles Taliaferro all defend substance dualism. I’m a substance dualist, myself.

What’s the objection to substance dualism?

The big objection to substance-dualism is the problem of how you get the non-physical substance to interact with the physical substance. It’s like how people put forward the grounding objection when talking about middle knowledge and where God’s knowledge of counterfactuals of creaturely freedom comes from. I wonder if anyone can post a comment for me to point me to a resource on answering the interaction problem in the comments.

UPDATE: One of my elite special forces ninja commenters writes:

Here’s Ed Feser on the Interaction Problem:

and

The thrust of his argument is that, if the soul is the extension of the body’s “form” without matter, then it interacts with the more material parts of us in the same way that forms in general interact with matter- this approach involves rethinking our metaphysical understanding of matter, rather than coming up with a clever idea of the soul, and it does get rather involved in Thomistic metaphysics, but I think it’s pretty interesting.

Evidence for the soul from science in the book “The Spiritual Brain”

7 Comments

I found a great book review of “The Spiritual Brain” on the Poached Egg – an excellent place for Christian apologists to find things to read. The book review is hosted at Probe Ministries and is authored by Heather Zeiger. The book talks about evidence from neuroscience showing that the mind cannot be reduced to merely physical processes.

Excerpt:

We have shown, however, how the evidence from neuroscience doesn’t seem to fit the materialistic worldview. As we will see, some experiments reported in The Spiritual Brain cannot be explained from this worldview. What we will find is that they fit nicely within a Christian worldview.

The first example is obsessive compulsive disorder therapy. Obsessive compulsive disorder, or OCD, occurs when a person has distressing or unwanted thoughts that dominate their thinking, and these obsessions trigger an urge to do some kind of ritual behavior, also known as a compulsion. The interesting thing about OCD is that the person knows that the obsession is irrational and the ritual won’t really fix it, but their feelings tell them otherwise. Scientific studies have shown that the brain is actually misfiring. The part of the brain that tells a person, “There’s a problem, do something to fix it,” is firing at the wrong times. OCD is a clear case of a healthy mind and a malfunctioning brain.

A materialistic worldview would say that the only way to treat OCD is by physically fixing the bad neurons. However, the treatment that actually works involves the patients mentally fixing the bad neurons. Patients learn to take control of their OCD by recognizing when their brain is misfiring, and try to starve the urges to do the ritual. After treatment, brain scans show that the brain of an OCD patient is starting to fix itself. The patient is changing his physical brain with his mind!

Similar kinds of therapies have been applied to depression and phobias.In both cases, The Spiritual Brain reports instances where a patient’s brain chemistry was directly affected by their mind.

Another phenomenon that can’t be explained from a materialist’s worldview is the placebo effect. The patient is given a medicine that they are told will help them, but in actuality they are given a sugar pill. Interestingly, the patient’s belief that the sugar pill will help them has caused measurable, observable relief from symptoms. Many doctors say that a patient’s attitude oftentimes can help or hinder real medicines or therapies from working.

The ability of the mind to change the brain’s chemistry does not fit within a materialistic worldview. But as Christians we know that our minds are very real and can have a very real effect on our physical bodies.

You can read more about the OCD research here. The scientist is Jeffrey M. Schwartz. He has also published work on this in peer-reviewed journals.

I liked “The Spiritual Brain” so much that I gave away copies to my co-workers a few years back. When I am talking to people about the mind and the brain, I like to augment the philosophical arguments (free will, intentionality, identity over time, etc.) with arguments from neuroscience, and even corroborative near death experiences. You can make a pretty good case for the soul if you pull together evidence from lots of disciplines.

By the way, if you like this topic, and want a resource to show your friends, be sure and get a hold of the debate on mind vs. brain between Jeffrey M. Schwartz and Michael Shermer.

UPDATE: I just received word from a commenter (below) that Dr. Beauregard has a new book coming out next year. Good news!
