Study: Writing by Hand is Good for the Brain. What Does that Say About ChatGPT?
Nothing can replace pen and paperIt might be time to get the pens and notebooks back out and shut off the keyboard for a while. Just pretend you’re back in the first grade and don’t have a minicomputer in your back pocket. Writing by hand can help stimulate the whole brain and stave off cognitive decline, according to a study by Van der Weel and Van der Meer (2024), as reported by Pamela B. Rutledge in Psychology Today. Using a more personal note, she writes, I’ve never been one to keep a journal, but I now wonder if the exclusive use of computers and the lack of handwriting practice is doing my brain a disservice by decreasing the activity of cortico-subcortical components of the writing Read More ›
Does ChatGPT Think?
Are Large Language Models like ChatGPT capable of legitimate thought?It’s one of the hot topic questions and will almost certainly continue to be. Are Large Language Models like ChatGPT capable of legitimate thought? And what counts as “thinking”? Is there a quality to the concept that makes it distinctly human, or are the tech futurists right? Can AI computation be considered a type of cognitive activity? Stephen Wolfram, George Gilder, and Bob Metcalfe spoke on the possibilities and limits of AI at last year’s star-studded COSM conference. We are experiencing watershed moments in technology, with lots of hype to go along with it, but are we putting the cart before the horse in some cases?

The Big Problem for Physicalism
One physicalist theory after another has either ignored or falsified the central characteristics of consciousnessEditor’s note: We are delighted to welcome the new book from Discovery Institute Press, Minding the Brain: Models of the Mind, Information, and Empirical Science, edited by Angus J. L. Menuge, Brian R. Krouse, and Robert J. Marks. Below is an excerpt from Chapter 2. Look for more information at MindingtheBrain.org. By Angus Menuge The history of physicalism is one of extraordinary diversity: a wide variety of theories, with multiple versions, have jockeyed for dominance. Yet it is also a tale of persistent failure. One physicalist theory after another has either ignored or falsified the central characteristics of consciousness, intentionality, and rationality that define our mental life. We will begin by tracing the history of physicalism from the early varieties of behaviorism Read More ›
Does Consciousness Defeat Materialism?
There is a re-emerging interest in consciousness and the mindWhat would it take for “consciousness,” undoubtedly a nebulous and broad term, to defeat the idea that the mind is no more than the brain? For Dean Radin, a parapsychology researcher who was featured on the Closer to Truth program this month, it depends on what you mean by matter. “If you just look through history about the nature of matter, how has it changed historically, it has become more and more ephemeral. And I will imagine it will continue to become more ephemeral,” he said. For Radin, then, matter is complicated, and if you look closely enough, ends up being “mostly nothing.” If you’ve seen the new Oppenheimer movie, directed by Christopher Nolan, perhaps you’ll remember the scene in Read More ›
Neuroscience, the Mind, and Theism
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
Sparks and Flashes of Remembrance
An expert in memory-loss treatment recalls some tender stories about memory in the midst of forgetfulnessIn 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 ›
Caring for the Deeply Forgetful
How can we compassionately relate to those suffering from Alzheimer’s disease? Is the mind more than the brain? Dr. Stephen Post, an expert in the field and author of Dignity for Deeply Forgetful People, speaks with neurosurgeon Michael Egnor on memory, consciousness, and whether the mind could have arisen from matter.

New Routledge Book on AI: It Won’t Take Us Over
The authors argue that, regardless of the benefits AI might provide in the future, it will never emulate the complex human neurocognitive system.A new book, Why Machines Will Never Rule the World, amplifies human exceptionalism and critiques the view that artificial intelligence will someday replace human beings. According to authors Jobst Landgrebe and Barry Smith, much of life and work can only be adequately navigated successfully with natural, not computerized, intelligence. They give two reasons for thinking that AI will never exceed human ingenuity: Echoing similar sympathies as Robert J. Marks in his book Non-Computable You: What You Do That Artificial Intelligence Never Will, Landgrebe and Smith argue that the concept of artificial general intelligence is mathematically impossible. A part of the book’s summary reads: Landgrebe and Smith show how a widespread fear about AI’s potential to bring about radical changes in Read More ›
Sean Carroll: “How Could an Immaterial Mind Affect the Body?”
The well known physicist thinks free will is nonsense. But has he investigated the classical understanding of causation?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 ›
Blinded by a Defunct Theory
The "interaction problem" is everywhere we look in physics, but the dogma of materialism remainsMaterialism. 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 ›
Is The Mind an Illusion?
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

Why Some Scientists Think Consciousness Persists After Death
We should not assume that people who are near death do not know what we are sayingA 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 ›
Can Crabs Think? Can Lobsters Feel? What We Know Now
In Switzerland, it is now illegal to boil a lobster alive. Are the Swiss right? Is it cruel?Because crustaceans have shells, we may tend to think of them as like machines. Yet crustaceans, along with octopuses, show some surprising abilities and complexities. Take crabs, for example: A new Swansea University study has revealed how common shore crabs can navigate their way around a complex maze and can even remember the route in order to find food … Spatial learning is quite complicated, so figuring out how it works in crustaceans gives us a better understanding of how widespread this ability, and learning in general, is in the animal kingdom.” The researchers tested 12 crabs over four weeks, placing food at the end of the maze each time. The route to the end of the maze required five Read More ›
Researchers Can’t Explain: Memories Drift From Neuron to Neuron
Memories are supposed to stay put in the neurons that lay them down. A recent study, published at Nature, shows that they move a lot…“Scientists are meant to know what’s going on, but in this particular case, we are deeply confused”, a recent article at The Atlantic begins. It’s about the way nervous system cells don’t simply lay down memories and keep them. The memories drift from neuron to neuron, quite contrary to textbook claims and traditional neuroscience assumptions: The relatively simple explanation found in neuroscience textbooks is that specific groups of neurons reliably fire when their owner smells a rose, sees a sunset, or hears a bell. These representations—these patterns of neural firing—presumably stay the same from one moment to the next. But as Schoonover, Fink, and others have found, they sometimes don’t. They change—and to a confusing and unexpected extent. Schoonover, Fink, Read More ›
