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 ›
The mind-body problem is much like the chicken-and-egg dilemma: Which came first? In today’s episode, Dr. Robert J. Marks sits down with Dr. Angus Menuge to discuss the basics of the mind-body problem, its philosophical history, and whether artificial intelligence ever has a chance at truly replicating the human mind.

Medieval Italian poet Dante Alighieri, exiled for life from his native Florence, took the opportunity to write a magnificent trilogy — the Divine Comedy — in which he tours Hell, Purgatory, and Heaven. The Comedy is more than a poetic masterpiece. It is a profound philosophical and theological reflection on this life and on eternity. Remarkably, although Dante’s immediate guides through the unseen worlds are, famously, the Roman poet Virgil (70 BC–19 BC) and later, a childhood sweetheart Beatrice (who died young), his philosophical guide is the philosopher and theologian Thomas Aquinas. The metaphysics, the ethics, and the theology of the Divine Comedy deeply reflect Thomas’s influence. That is remarkable, considering that Dante (1265–1321 AD), who was only a child Read More ›
In last week’s podcast,” our guest host, neurosurgeon Michael Egnor, interviewed philosopher of science Bruce Gordon on “Idealism and the Nature of Reality.” Idealism is the view that “something mental (the mind, spirit, reason, will) is the ultimate foundation of all reality, or even exhaustive of reality” – Stanford Encyclopedia of Philosophy. As Gordon noted in the earlier portion of this podcast, idealism is actually a practical philosophy. It originated with Plato (c. 424–347 BC) but the modern form, which he himself holds, is that of George Berkeley (1685–1753). In Berkeley’s view everything that exists is an idea in the mind of God. Thus, Dr. Egnor asked him what he thinks of panpsychism, the view that everything in the universe Read More ›
In last week’s podcast, “The Chaitin Interview IV: Knowability and Unknowability,” Walter Bradley Center director Robert J. Marks interviewed mathematician Gregory Chaitin, best known for Chaitin’s Unknowable Number, on, among other things, consciousness. What can mathematics contribute to the discussion. Also, what does Chaitin think about panpsychism (everything is conscious”)? The discussion began with reference to David Chalmers’s 1996 book, The Conscious Mind: In Search of a Fundamental Theory, in which Chalmers coined the term “Hard Problem of Consciousness.” The term acknowledged what everyone knew, that human consciousness is a very difficult problem to understand, especially from a materialist perspective.Are there other approaches? Chaitin offers a look at the challenge panpsychism presents to materialism: https://episodes.castos.com/mindmatters/Mind-Matters-127-Gregory-Chaitin.mp3 This portion begins at 28:25 Read More ›
In Part 1 of this series, we saw how the belief that “every human thought is an illusion” proves empty and powerless when trying to account for the infinity mirror experience. Part 2 here puts another view held widely by science-trained people, materialism, to the same mirror test. Materialism is the view that everything we observe results from the interplay of matter and energy. Under materialism, each human’s every thought is produced by electrochemical events in the brain. As Marvin Minsky, an artificial intelligence pioneer, wrote in Society of Mind (1988), “Everything, including that which happens in our brains, depends on these and only on these: A set of fixed, deterministic laws and a purely random set of accidents.” Philosopher Read More ›
Bernardo Kastrup, a Dutch computer scientist and philosopher who has published fundamental theoretical reflections on the mind matter problem, offers some useful reflections on why materialism can’t really be true. First—and we sometimes forget this—science only exists as it is perceived by the human mind. We could do it well or badly or someway in between. We could succeed or fail. But it is a world of ideas, not things. He writes, Materialism—the view that nature is fundamentally constituted by matter outside and independent of mind—is a metaphysics, in that it makes statements about what nature essentially is. As such, it is also a theoretical inference: we cannot empirically observe matter outside and independent of mind, for we are forever Read More ›
My friend and colleague Bill Dembski, a leading advocate of intelligent design of the universe and life forms, has done a superb short interview with Robert Lawrence Kuhn on Closer to Truth. Bill takes a position that will surprise many fellow Christians—he doesn’t believe that consciousness represents an insurmountable challenge to materialism: Bill makes the point that much of the popular argument hinges on shifting meanings of “materialism” and “consciousness.” By contrast, he argues, the design inference in biology is a much more effective challenge to materialism. I agree that design in nature is an effective challenge to materialism. But I also believe that the mind refutes materialism in a rather straightforward way—and in much the same way that evidence Read More ›
Last month, materialist neurologist Steven Novella made a rather astonishing claim in a post at his Neurologica blog: A recent open-access study of learning and decision-making in mice shows that the human mind is merely what the human brain does. That’s a lot for mice to prove. In the study, the mice were trained to choose holes from which food is provided. Their brain activity was measured as they learned and decided which holes were best. The research looks specifically at quick and intuitive decision-making vs. decision-making that is slower and involves analysis of the situation. The investigators found that analysis-based decisions in the mice involve brain activity in the anterior cingulate cortex, which is a region of the brain Read More ›
Manuel Brenner, a particle physicist who became a theoretical neuroscientist, made the argument last year that human intelligence is less complex than we make it out to be. Thus, building an artificial intelligence might be easier than we suppose. He offers some intriguing arguments and here are some responses: ➤ Is the information we need for building human-like AI in our genes? He doesn’t think so because a tomato has 7000 more genes than a human being. Further, our human genome offers only 25 million bytes of information for our brain’s design but there are 1015 connections in the adult neocortex. His conclusion? “there needs to be a much simpler, more efficient way of defining the blueprint for our brain Read More ›
In a recent report, Nature addressed several studies on disembodied brains grown in the lab. One of those studies, published last year by Alysson Muotri of the University of California, San Diego, showed that brain organoids (organized clusters of brain cells) displayed electrical signals reminiscent of a twenty-five-week-old pre-term baby. the electrical activity continued for several months until the experiment was eventually stopped. Experiments with such brain organoids have left many wondering whether we should be concerned about creating brains-in-a-dish. Organoids, such as those made of kidney or liver cells, have been used to study drug development and disease. They are made either from embryonic stem cells—an ethically problematic source because they involve the destruction of an embryo—or induced pluripotent Read More ›
Free will is a contentious topic in science these days. Theoretical physicists weigh in sharply on one side or the other. Just this month, based on quantum mechanics, mathematician Tim Andersen says maybe and theoretical physicist Sabine Hossenfelder says no. Based on cosmology, the study of our universe, physicist George Ellis said yes last June. With free will, as with consciousness, we don’t fully understand what’s involved. All insights from science are partial so we can’t look to science for a definitive answer. But maybe science can offer some hints. Here are four that might be helpful: 1.Has psychology shown that free will does not really exist? Psychological research on free will has supported the concept of free will but Read More ›
In a recent podcast, “Does the Moon Exist if No One is Looking at It?”, Michael Egnor continued his discussion with philosopher and computer programmer Bernardo Kastrup. As a scientist, Kastrup has worked for The European Organization for Nuclear Research and for Phillips Research Laboratories, and has authored many academic papers and books. This week’s topic is the way physics today points to mind as opposed to materialism. Kastrup offers some thoughts on God and free will as well, from his cosmopsychist (or objective idealist) position: https://episodes.castos.com/mindmatters/Mind-Matters-095-Bernardo-Kastrup.mp3 From the transcript: (Other discussions in the series, Show Notes, Resources, and a link to the complete transcript follow.)
