What makes humans unique compared to the rest of the natural world? Can strict materialists answer that question? In today’s podcast episode, neurosurgeon Michael Egnor speaks with Dr. Joshua Farris on the idea that human beings are made in God’s image, the mystery of consciousness, and panpsychism.

A century ago, many scientists — though certainly not all — cherished the hope that science would some day show that our universe is entirely determined by laws of physics physicalism. Neuroscientists insisted, along these lines, that the mind is simply the physical processes of the brain. But neuroscience is identifying many facts that show that the mind is independent of the brain. While working on the book that neurosurgeon Michael Egnor and I are writing on neuroscience evidence for the human soul (Worthy, 2024), I learned something remarkable: Some people’s brains have been split in half (corpus callosotomy) to treat otherwise intractable epilepsy) typically continue to think normally. For people who believe that the mind is simply the buzz Read More ›
In case you missed it, earlier this month we released a podcast featuring a provocative conversation between Stony Brook neurosurgeon Michael Egnor and Dr. Joshua Farris, who specializes in the theological anthropology and philosophy of mind. Together they discuss a range of issues, including the thought of the philosopher René Descartes, Thomistic dualism, materialistic explanations for consciousness, and the inevitability of metaphysics when discussing the “mind-body problem.” Follow this link to listen to it for free.
What impact did the ideas of the philosopher René Descartes have on our modern conception of the mind/body problem? In today’s episode, neurosurgeon Michael Egnor digs deeper into his conversation with Dr. Joshua Farris, discussing Thomistic dualism, materialistic explanations for consciousness, and the inevitability of metaphysics.

Not surprisingly, given that philosopher David Chalmers won the famous wager with neuroscientist Christof Koch last month, the topic of consciousness has been in the news a lot. In 25 years of research, no one has found a specific consciousness circuit, spot, wave, or whatever in the brain. Consciousness is still the “Hard Problem of Consciousness.” At Vox, Oshan Jarow, a writer who knows the field, tells us that the bet has been renewed for another 25 years and offers an interpretation of why scientists haven’t “cracked” consciousness so far: “we still lack a definitive, falsifiable explanation. We even lack consensus on whether one may ever exist.” Eventually, in this view, the field might coalesce around a unified theory and Read More ›
Even since neuroscientists started imaging the brain, they’ve been turning up cases where people are missing brain parts we would expect them to need in order to do something — but they are doing that very thing anyway. One example, written up in LiveScience in 2019, concerns women who are missing their olfactory bulbs (illustrated) but can still smell: Researchers have discovered a small group of people that seem to defy medical science: They can smell despite lacking “olfactory bulbs,” the region in the front of the brain that processes information about smells from the nose. It’s not clear how they are able to do this, but the findings suggest that the human brain may have a greater ability to Read More ›
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
Back in 1998, premier neuroscientist Christof Koch had wagered philosopher of mind David Chalmers a case of fine wine that within the next twenty-five years, a specific “signature of consciousness” would be found in the brain. In 2018, Swedish journalist Per Snaprud reminded the world of that fact at New Scientist. With five years to run, a countdown of sorts began. Snaprud’s article was titled “Consciousness: How we’re solving a mystery bigger than our minds,” telling readers that “we’re uncovering clues.” The five years are up and who won? Mariana Lenharo reports at Nature, “Both scientists agreed publicly on 23 June, at the annual meeting of the Association for the Scientific Study of Consciousness (ASSC) in New York City, that Read More ›
University of Missouri psychology professor Kennon Sheldon’s message is neatly summed up in an opening statement: “Regardless of whether humans do or don’t have free will, psychological research shows it’s beneficial to act as if you do”. The author of Freely Determined: What the New Psychology of the Self Teaches Us About How to Live (Basic Books, 2022) responds to philosophers who say that we do not have free will: All my life, I’ve struggled with the question of whether humans have ‘free will’. It catalysed my decision to become a psychologist and continues to inspire my research to this day, especially as it relates to the kinds of goals people set for themselves, and the effects of goal-striving on Read More ›
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 ›
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.

Robert J. Marks, director of the Walter Bradley Center for Natural & Artificial Intelligence, sat down with former Google employee Blake Lemoine, who made headlines last year when he claimed AI can be “sentient.” The claim also led to his departure from Google. The two had a fascinating conversation, to say the least. In today’s episode, they discuss whether AI can indeed become sentient, the non-computability of certain human traits, and the question of the soul. Marks and Lemoine couldn’t differ more on these fundamental points. Whereas Lemoine thinks AI can be sentient, Marks firmly rejects such a notion. In addition, Lemoine’s materialistic worldview controls his understanding of the brain, while Marks defends the existence of the immaterial mind. While 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 ›

Columbia University neurologist Jan Claassen and Harvard medical school neurologist Brian L. Edlow introduce us to a vital new concept in consciousness: “covert consciousness,” which is experienced by 15–20% of people who are in a coma: Thirty-year-old New York City resident Maria Murkevich, for example, suffered a ruptured blood vessel in her brain and was comatose. Conventional tests (wiggle your toes, etc.) produced no response but her loved ones still believed she was “in there.”: They were right. But it took a high-tech method to demonstrate that: The medical team gave her an EEG — placing sensors on her head to monitor her brain’s electrical activity — while they asked her to “keep opening and closing your right hand.” Then Read More ›

Neurosurgeon Michael Egnor offers a look at the radical trend to medicine and life-altering surgery based on teen identity issues: Despite the logical gibberish, trans-activism has had a frightening impact on medical practice and medical ethics. ‘Gender affirmation’ clinics exist in medical centers across the country, and many clinics offer hormonal treatment and even radical surgery to children and adults. Boston Children’s Hospital — probably the most prominent children’s hospital in the country — has offered mastectomies to girls as young as 15 for “gender reassignment,” and has offered patients phalloplasty (the surgical creation of a ‘penis’), metoidioplasty (cutting tissue to lengthen the clitoris), creation of a scrotum with testicular implants, hysterectomy, vaginoplasty (amputation of the penis and testicles with construction of a ‘vagina’) Read More ›
Recently, paleontologist Günter Bechly took issue with neurosurgeon Michael Egnor on the question of whether spiders dream. Egnor was willing to accept the possibility, noting that spiders can dream only about things they can think about: “If spiders and bacteria dream, they dream of flies or chemical gradients, but not of philosophy.” Bechly, on the other hand, thinks it’s a filament too far for the spider (never mind the bacteria) to dream at all: … I tend to concur with those neuroscientists who doubt any organisms possess phenomenal consciousness that lack a neocortex (found only in mammals) or a comparable structure (in birds and maybe cephalopods). Rapid eye movement may indicate neural activity, but the concept of dreaming for me Read More ›
Yesterday, we ran a story about a recent study in which 40 people who had half of their brains removed (hemispherectomy) as children — due to intractable epilepsy — did unexpectedly well on psychological tests. Some say that it’s easy to explain because the brain has so many redundant elements. But is that all we need to know? We asked pediatric neurosurgeon Michael Egnor for some thoughts on that approach and he replied: The means by which people with major parts of their brains removed maintain function are not understood. It’s nonsense to say, as some do, that “The brain is massively parallel and recursive and functions under network rules and laws.” That’s typical neuroscience gibberish. The fact is that Read More ›
At Carnegie Mellon University’s Department of Psychology and Neuroscience Institute, researchers recently found that people who had had half their brains removed as children (due to serious epilepsy) “scored surprisingly well on face and word recognition tests”: The researchers expected that those volunteers who had only their right hemisphere would do well at face recognition but not as well at word recognition, since the right hemisphere is generally used to process images while the left hemisphere processes words; they expected the opposite results for those who still had just their left hemisphere. Instead, the researchers found that both groups performed nearly equally well and both were on average 86% accurate on the tests compared to a control group consisting of Read More ›
