What can modern neuroscience teach us about the immaterial mind? Can we ever know anything for certain? In this episode, neurosurgeon Michael Egnor talks with anthropologist Dr. Joshua Farris. They discuss the brain, Descartes, and the theological implications of the various philosophies of mind. Additional Resources
In a recent Mind Matters podcast episode, neurosurgeon Michael Egnor (Mike), a frequent contributor to the site, interviewed friend and colleague Stephen Post, an expert in memory-loss-related disorders. Here’s a snippet of their conversation, which you can enjoy in full by following this link. Mike Egnor: So to begin, your new book, Dignity for Deeply Forgetful People, why did you use that title and what do you mean by deeply forgetful people? Stephen Post: Well, that’s a fabulous question to begin with because the title doesn’t quite say it all, but it’s close. I’ve been working with deeply forgetful people and their caregivers since I went out to Case Medical School in 1988, and I have never felt comfortable with Read More ›
Can ChatGPT write funny jokes? The answer is yes. To try and generate some short jokes, I went to ChatGPT and started all my queries with: “Complete the following to make it funny:” Doing so alerts ChatGPT about my end goal. Without this preamble, I could make queries all day and get no funny responses. I started with the beginnings of some well-known quotes. To Be or Not to Be Consider for example the quote from Shakespeare’s Hamlet: “To be or not to be, that is the question.” I instructed ChatGPT with the following command: “Complete the following to make it funny: To be or not to be…” One of the better responses I got was “To be or Read More ›
Sometimes AI seems a bit of a niche idea, relegated to dystopian prophecies or sentient robots. But AI is much more pervasive and influential in our present world in more ways than we might assume. Oxford mathematician John Lennox reminds us in this recent podcast episode that our society teems with AI. Lennox commented, Now, the final example I would give you is the fact that we’re all involved in AI. That is any of us who own a smartphone, it’s tracking us all the time. What many of us don’t realize is that, for example, we make a purchase at Amazon. A few days later, we’ll get a pop-up saying, people that bought this book were interested in that Read More ›
Bob and Sue were on their way to church one morning. On their way they ran into their friend Fred. Fred was very wealthy, a billionaire in fact. Fred waved hi. Bob and Sue waved back. They asked Fred to come with them to church. Fred said no, he had more important things to do. “What is so important,” asked Sue. “I’m off to the real deal,” beamed Fred. Bob looked confused. “Real deal about what?” “You have a fake promise of eternal life. I’m about to get the real thing.” “You can’t be serious. Start talking some sense.” “Seriously. Here’s my voucher, see it right here.” Sue grabbed the piece of paper from Fred and read it aloud. “Good for one digital immortalization Read More ›
AI image generators like Midjourney or DALL-E are generally adept at capturing the accuracy of the human form. The concerns over copyright, job infringement, and general degradation of the visual arts via such AI are ongoing concerns for many artists and practitioners. However, a new New Yorker article by Kyle Chayka identifies a noticeable flaw in AI artwork: human hands. Missing the Big Picture Chayka begins by recalling an art class where he was asked to draw his own hand. It’s an assignment for beginners, and as behooves a novice, tempts the artist to focus more on the specific contours of the hand instead of the overall structure and form. The forest gets lost in the trees, so to speak. Read More ›
Kenneth Miller is a biologist at Brown University who has been very active in his written and vocal support for Darwin’s theory of evolution. He’s neither a materialist nor an atheist – he is a Catholic, and in being one of the rare Darwinists who doesn’t subscribe wholeheartedly to the materialist/atheist paradigm, he allows himself to be used as a token theist by the Darwinists. It helps his career, no doubt, but doesn’t advance the truth. Not an admirable place to be. Miller’s New Book and What it Misses In his 2018 book The Human Instinct: How We Evolved To Have Reason, Consciousness, and Free Will, Miller manages a feat uncommon even for Darwinists – even the title of the Read More ›
Sean Carroll is a theoretical physicist at Johns Hopkins University who takes an atheist and materialist philosophical perspective on nature and on science. I have disagreed with him often — I’m in no position to judge his scientific acumen, but his philosophical acumen leaves a lot to be desired. An example of this is a question he asks in a recent documentary about free will (which I haven’t watched yet). In the trailer for the movie, Carroll asks, How in the world does the immaterial mind affect the physical body? Carroll’s denial of libertarian free will is based on this question, and of course, he believes that the immaterial mind does not exist and, if it did exist, could not Read More ›
Materialism. What a weird word. It sounds like a ghost, materializing in front of me. And it is sort of like a ghost, one that has mysteriously taken over the minds of many intelligent people. Because they believe in materialism, these smart people don’t believe in ghosts. Especially the ghost in the machine. The problem is there is no way for the ghost to interact with the machine. This is known as the “mind-body interaction problem”. The great thing about materialism is at least that theory doesn’t have an interaction problem. Any material thing can interact with any other material thing. Yet there is a deep irony. Let’s explore the idea of materialism to see why. Materialism is the idea that reality only consists of matter. Read More ›
Perhaps you’ve heard of the “mind-body problem,” but what about the relationship between the mind and the brain? Is the mind just an illusion produced by the brain or is it something totally separate? Robert Marks talks with neurologist Andrew Knox on these topics and more in this week’s Mind Matters podcast episode. Additional Resources
ChatGPT, OpenAI’s new artificial intelligence chatbot, has made headlines for over a month now, and for good reason. It’s an advanced bot designed to problem solve. It can “converse” with people on a range of topics. A problem for us to solve now is how to deal with ChatGPT’s invasion into the sphere of education. Students report using ChatGPT on final exams and papers according to a recent write-up from The College Fix. One College of Staten Island student used the bot on both final exams and “got As on both.” He commented that “half the kids in my class used it.” The student also noted that he used the chatbot to complete a multiple-choice exam, on which he got Read More ›
In my last post, I wrote about a novelist who used a version of the AI art tool known as Stable Diffusion to gather images for a promotional website. She wanted erotic and violent elements in the artwork and found that other AI art tools included “guardrails” limiting access to graphic results. But if these images are disconnected from a human, imaginative process, can we say AI-generated results qualify as creative works? Artificial intelligence doesn’t only challenge our notions of what it means to be human. It also makes us wonder what it means to make art and whether human beings are the only agents capable of creating it. Walter Kirn addressed this question poignantly in a Substack essay. Kirn Read More ›
Neurotheology is the study of the relationship of our religious and spiritual selves and our brains. How can studying our brains give us insight into our minds? Dr. Michael Egnor interviews Dr. Andrew Newberg on neuroscience, methods of studying the brain, and how our minds and brains are related. Show Notes Additional Resources

A very significant change that happened in the last century or so has been the ability of science professionals to see what happens when people are thinking, especially under traumatic conditions. It was not a good moment for materialist theories. Here is one finding (there are many others): Death is a process, usually, not simply an event. Consciousness can persists after clinical death. A more accurate way of putting things might be that the brain is able to host consciousness for a short period after clinical death. Some notes on recent findings: The short answer is, probably, yes: Recent studies have shown that animals experience a surge in brain activity in the minutes after death. And people in the first Read More ›
If no one is looking at the moon, does it exist? Why has materialism been around for so long? Will computers ever be conscious? What happens to our consciousness after we die? Bernardo Kastrup tackles these questions and more with Michael Egnor in another bingecast! Show Notes Additional Resources
In this Bingecast episode, Dr. Robert J. Marks and Dr. Michael Egnor explore the human brain and its relationship to the mind. Is the mind an emergent property of the brain? Is there neurological evidence for the soul? What have brain experiments taught us about free will and the human person? Can you still think in a coma? Show Notes Read More ›
In this week’s podcast, Walter Bradley Center director Robert J. Marks interviews Concordia University philosopher Angus Menuge on the notoriously difficult mind–body problem. Dr. Marks asks, “Is there a part of you that is not physical? Are we meat puppets limited to scientific analysis described totally by the laws of nature? “ That’s the mind–body problem! It’s more complex today because some claim we will build computers that have minds like humans (but not bodies like humans). But first, how do we know we are not just bodies? https://episodes.castos.com/mindmatters/Mind-Matters-133-Angus-Menuge.mp3 This portion begins at 04:06 min. A partial transcript, Show Notes, and Additional Resources follow. Angus Menuge (pictured): Well, the real question is how two such different realms can relate. If Read More ›
Cognitive neuroscientist Stephen M. Fleming, author of Know Thyself: The Science of Self-Awareness (2021), offers an excerpt at Slate in which he implies that we have made some headway in understanding self-awareness. Size alone is not the key to intellectual capacity, he says, but rather the “brain soup,” the number of neurons that can be packed into the brain. Primates of all types (monkeys, apes, and humans) are much more efficient at packing neurons into the brain than rodents are: “Regardless of their position on the tree, it seems that primates are evolutionary outliers—but, relative to other primates, humans are not.” He points to a portion of the prefrontal cortex, the “association cortex” which is “particularly well-developed” in humans, relative Read More ›
Kelsey Ichikawa has just published a superb essay about the pitfalls of functional magnetic resonance imaging (fMRI) of the brain. Ms. Ichikawa (pictured), who describes herself as a ”budding” neuroscientist who graduated last year from Harvard, discusses the snares into which misinterpretation can lead us. fMRI brain scanning is a relatively new technology in which researchers and clinicians use magnetic resonance images (MRI) of the brain to detect brain activity almost as it happens. The technique is widely used, both for clinical care of patients (neurosurgeons use it to map sensitive parts of the brain prior to surgery) and for research purposes. A major thrust of neuroscience research in the last couple of decades has been the use of fMRI Read More ›
