Study by UCLA neuroscientist Jeffrey Schwartz falsifies materialist determinism

Here’s a summary of the research of UCLA professor Jeffrey Schwartz, authored by William Dembski.

Excerpt:

Schwartz provides a nonmaterialist interpretation of neuroscience and argues that this interpretation is more compelling than the standard materialist interpretation. He arrived at this position as a psychiatrist specializing in the treatment of obsessive-compulsive disorder (OCD). OCD sufferers recognize obsessive-compulsive thoughts and urges as separate from their intrinsic selves. For instance, after a few washings, the compulsive hand-washer realizes that his hands are clean and yet feels driven to keep washing them. It was reflection on this difference between the obvious truth (the hands are clean) and the irrational doubts (they might still be dirty) that prompted Schwartz to reassess the philosophical underpinnings of neuroscience.

From brain scans, Schwartz found that certain regions in the brain of OCD patients (the caudate nucleus in particular) exhibited abnormal patterns of activity. By itself this finding is consistent with a materialist view of mind (if, as materialism requires, the brain enables the mind, then abnormal patterns of brain activity are likely to be correlated with dysfunctional mental states). Nonetheless, having found abnormal patterns of brain activity, Schwartz then had OCD patients engage in intensive mental effort through what he called relabeling, reattributing, refocusing, and revaluing (the 4 Rs). In the case of compulsive hand-washing, this involved a patient acknowledging that his hands were in fact clean (relabeling); attributing anxieties and doubts about his hands being dirty to a misfunctioning brain (reattributing); directing his thoughts and actions away from handwashing and toward productive ends (refocusing); and, lastly, understanding at a deep level the senselessness of OCD messages (revaluing).

Schwartz documents not only that patients who undertook this therapy experienced considerable relief from OCD symptoms, but also that their brain scans indicated a lasting realignment of brain-activity patterns. Thus, without any intervention directly affecting their brains, OCD patients were able to reorganize their brains by intentionally modifying their thoughts and behaviors. The important point for Schwartz here is not simply that modified thoughts and behaviors permanently altered patterns of brain activity, but that such modifications resulted from, as he calls it, “mindful attention”-conscious and purposive thoughts or actions in which the agent adopts the stance of a detached observer.

So mind-brain interaction is not a one-way street. Everyone knows that you can alter your consciousness, beliefs, moods, sensations, etc. by changing your brain, e.g. – with drugs. But it turns out that you can also will to focus your thoughts on certain things in order to change your brain chemistry. So the causation is not just bottom-up, but also top-down.

Now mindfulness therapies – which are documented in the research papers published by Schwartz (like this one and this one and this one)- assume the existence of free will. Naturalists don’t like these scientific publications because naturalists don’t believe in free will, as the famous naturalist philosopher Alex Rosenberg explained in his debate with William Lane Craig.

This post from Uncommon Descent explains the naturalist conundrum.

Excerpt:

The issue, for Schwartz, turns on whether or not there is such a thing as free will. The assumption of free will is critical to mindfulness therapies for practical purposes.

Philosophies and religions have various opinions about ultimate free will. The therapist must ask, is my patient capable of carrying out a program that requires that he choose to focus his attention on A and not B? In practice, this turns out to be true for many patients, which makes the therapy useful. There is neuroscience evidence for brain reorganization as a result, showing that it is not merely an imagined effect.

Now, if someone wishes to claim, as many outspoken advocates of Darwinian evolution have, for example, that free will is impossible, the only thing that a mindfulness therapist can say is, go away. Either they are mistaken or the research results from mindfulness therapies are.

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.

Six reasons why you should believe in non-physical souls

11 Comments

This podcast is a must-listen. Please take the time to download this podcast and listen to it. I guarantee that you will love this podcast. I even recommended it to my Dad and I almost never do that.

Details:

In this podcast, J. Warner examines the evidence for the existence of the mind (and inferentially, the soul) as he looks at six classic philosophical arguments. Jim also briefly discusses Thomas Nagel’s book, Mind and Cosmos and discusses the limitations of physicalism.

The MP3 file is here. (67 MB, 72 minutes)

Topics:

  • Atheist Thomas Nagel’s latest book “Mind and Cosmos” makes the case that materialism cannot account for the evidence of mental phenomena
  • Nagel writes in this recent New York Times article that materialism cannot account for the reality of consciousness, meaning, intention and purpose
  • Quote from the Nagel article:

Even though the theistic outlook, in some versions, is consistent with the available scientific evidence, I don’t believe it, and am drawn instead to a naturalistic, though non-materialist, alternative. Mind, I suspect, is not an inexplicable accident or a divine and anomalous gift but a basic aspect of nature that we will not understand until we transcend the built-in limits of contemporary scientific orthodoxy.

  • When looking at this question, it’s important to not have our conclusions pre-determined by presupposing materialism or atheism
  • If your mind/soul doesn’t exist and you are a purely physical being then that is a defeater for Christianity, so we need to respond
  • Traditionally, Christians have been committed to a view of human nature called “dualism” – human beings are souls who have bodies
  • The best way* to argue for the existence of the soul is using philosophical arguments

The case:

  • The law of identity says that if A = B’ if A and B have the exact same properties
  • If A = the mind and B = the brain, then is A identical to B?
  • Wallace will present 6 arguments to show that A is not identical to B because they have different properties

Not everyone of the arguments below might make sense to you, but you will probably find one or two that strike you as correct. Some of the points are more illustrative than persuasive, like #2. However, I do find #3, #5 and #6 persuasive.

1) First-person access to mental properties

  • Thought experiment: Imagine your dream car, and picture it clearly in your mind
  • If we invited an artist to come and sketch out your dream car, then we could see your dream car’s shape on paper
  • This concept of your dream car is not something that people can see by looking at your brain structure
  • Physical properties can be physically accessed, but the properties of your dream care and privately accessed

2) Our experience of consciousness implies that we are not our bodies

  • Common sense notion of personhood is that we own our bodies, but we are not our bodies

3) Persistent self-identity through time

  • Thought experiment: replacing a new car with an old car one piece at a time
  • When you change even the smallest part of a physical object, it changes the identity of that object
  • Similarly, your body is undergoing changes constantly over time
  • Every cell in your body is different from the body you had 10 years ago
  • Even your brain cells undergo changes (see this from New Scientist – WK)
  • If you are the same person you were 10 years ago, then you are not your physical body

4) Mental properties cannot be measured like physical objects

  • Physical objects can be measured (e.g. – use physical measurements to measure weight, size, etc.)
  • Mental properties cannot be measured

5) Intentionality or About-ness

  • Mental entities can refer to realities that are physical, something outside of themselves
  • A tree is not about anything, it just is a physical object
  • But you can have thoughts about the tree out there in the garden that needs water

6) Free will and personal responsibility

  • If humans are purely physical, then all our actions are determined by sensory inputs and genetic programming
  • Biological determinism is not compatible with free will, and free will is required for personal responsibility
  • Our experience of moral choices and moral responsibility requires free will, and free will requires minds/souls

He spends the last 10 minutes of the podcast responding to naturalistic objections to the mind/soul hypothesis.

*Now in the podcast, Wallace does say that scientific evidence is not the best kind of evidence to use when discussing this issue of body/soul and mind/brain. But I did blog before about two pieces of evidence that I think are relevant to this discussion: corroborated near-death experiences and mental effort.

You might remember that Dr. Craig brought up the issue of substance dualism, and the argument from intentionality (“aboutness”), in his debate with the naturalist philosopher Alex Rosenberg, so this argument about dualism is battle-ready. You can add it to your list of arguments for Christian theism along with all the other arguments like the Big Bang, the fine-tuning, the origin of life, stellar habitability, galactic habitability, irreducible complexity, molecular machines, the Cambrian explosion, the moral argument, the resurrection, biological convergence, and so on.

Commentary

What does the concept of resurrection mean to Jewish theologians?

1 Comment

Here’s a helpful post from Eric Chabot talks about this and other interesting topics related to the resurrection.

Excerpt:

Where do we see resurrection in the Hebrew Bible?

As just stated, belief in a resurrection of persons from the dead are seen in eight passages: (Job 19:26; Ps. 17:15; 49:15; 73:24; Is. 26:19; 53:10; Dn. 12:2;12:13). The resurrection terminology is seen in two places (Ezek. 37:1-14; Hos. 6:2) to show a national and spiritual restoration brought about by the return from the exile. As far as the nature of the future bodily resurrection, it may involve a corpse or the receipt of a material body comparable to the present physical body (Job 19:26; Is. 26:19), or it may be a matter of transformation (Dn. 12:2-3 and perhaps 12:13); or glorification after reanimation, in the case of the righteous.

As far as the function of the resurrection, it may be personal vindication (Is. 26:16; 53:10-12). Resurrection may also have a function in relation to reward or punishment (Dn. 12:2; 12:13), an assumption to heaven and enriched fellowship with God (Ps. 49:15; 73:24,26), or preface to the beatific vision of God (Ps. 17:15 and possibly Job 19:26). (1)

The Greek word for resurrection is “anatasis” which means “a raising up” or “rising.” There are resuscitations in the Tanakh such as the example of Elijah and Elisha raising a person from death (1 Kings 17-23; 2 Kings 4:34-35). While these figures may have been raised in a resurrection sense, they were not raised immortal in the same way Jesus was.

Extra-Biblical Passages on Resurrection

There are also extra-biblical passages that speak about the resurrection (Enoch 92:2; 4 Ezra 7:32; Enoch 91:10; 2 Maccabees 7:9; 14; 28-29). Even the The Messiah Apocalypse, which is dated between 100 and 80 B.C.E mentions resurrection: “He [God] frees the captives, makes the blind see, and makes the bent over stand straight…for he will heal the sick, revive the dead, and give good news to the humble and the poor he will satisfy, the abandoned he will lead, and the hungry he will make rich.” (2)

In the Rabbinical literature there are explicit teachings on the resurrection. It says in the Mishnah 10.1, it says, “All Israelites have a share in the world to come; … and these are they that have no share in the world to come: he that says that there is no resurrection of the dead prescribed in the Law.” Moses Maimonides, a Jewish rabbi and a medieval Jewish philosopher who has forever influenced the Jewish and non-Jewish world said:

” The resurrection of the dead is one of the cardinal principles established by Moses our teacher. A person who does not believe this principle has no real religion, certainly not Judaism. However, resurrection is for the righteous. This is the earning of the statement in Breshit Rabbah, which declares: “the creative power of rain is both for the righteous and the wicked, but the resurrection of the dead is only for the righteous.” Our sages taught the wicked are called dead even when they are still alive; the righteous are alive even when they are dead” (Bab. Talmud Brakhot 18 b).

3 points are made here: 1. Resurrection is a cardinal principle taught in the Torah which all Jews must believe 2. It is for the righteous alone 3. All men must die and their bodies decompose. (3)

It’s important to understand that the concept of resurrection had a meaning before Christianity ever started. And it’s interesting to ask why the early Christians applied the notion of resurrection to Jesus. What is the best explanation for their decision to do such a strange thing? Why not just give up on him and deny that he was the Messiah when he was killed by the Romans?
