How a Neurosurgeon Showed That Abstract Thought Is Immaterial
Wilder Penfield, one of the first neurosurgeons to split human brains in half to relieve epilepsy, found much more than a treatment
The Reality of the Mind: The Argument From Epilepsy
Why do epileptic seizures evoke many odd behaviors but not abstract thought?In the recent debate between neurosurgeon Michael Egnor and philosopher David Papineau, “Atheist Philosopher and Christian Neurosurgeon Debate Materialism” at Theology Unleashed, there was sort of digression at 49:30 on the nature of thought. Dr. Egnor talks about what he learned from his experiences with treating epilepsy and Dr. Papineau responds. Note: Dr. Papineau is a “physicalist.” On that view, “the mind is a purely physical construct, and will eventually be explained entirely by physical theory, as it continues to evolve.” (Philosophy basics) He is considered to be one of the best defenders of naturalism (nature is all there is), often called “materialism.” Michael Egnor: There are three metaphysical questions that I think can be answered in an inferential way, Read More ›
Why, as a Neurosurgeon, I Believe in Free Will
The spiritual aspect of the human soul, sadly, leaves its signature in epilepsyIn his classic book, Mystery of the Mind, (1975) epilepsy surgery pioneer Dr. Wilder Penfield, asked a significant question: “Why are there no intellectual seizures?” Epileptic seizures can be experienced in a variety of ways—convulsions of the whole body, slight twitching of a muscle, compulsive memories, emotions, perceptions of smells or flashes of light, complex motor behaviors such as chewing or laughing or even walking, or subtle moments of inattention. But seizures never have intellectual content. There are no intellectual seizures, which is odd, given that large regions of the brain are presumed by neuroscientists to serve intellectual thought. It is all the more remarkable when we consider that seizures commonly originate in these “intellectual” areas of the brain. Yet Read More ›
Neuroscience Refutes Free Will? Addressing an Objection
Functional magnetic resonance imaging (fMRI) is not as good as Libet’s methods for assessing real-time effectsIn reply to a post in which I pointed out that neuroscience strongly supports the reality of free will, commenter AaronS1978 makes a point at Uncommon Descent: First Michael Egnor is wrong about there being no brain wave activity with free won’t Patrick Haggard in 2014 discovered accidotal brain waves to free won’t I feel he kind of makes declarations, I understand his position philosophically and I do agree with a lot of it, but saying there is no activity before free won’t and saying it’s immaterial is incorrect Furthermore why wouldn’t there be brain activity when exercising your will? Wouldn’t that just mean that your soul was using your brain? Isn’t consciousness and conscious experience (hard problem of the Read More ›
Neuroscience Can Help Us Understand Why Free Will Is Real
Physicist Sabine Hossenfelder and biologist Jerry Coyne, who deny free will, don’t seem to understand the neuroscienceEvolutionary biologist Jerry Coyne seems obsessed with denying free will. In a recent post on his blog, Why Evolution Is True, he supported the claim of theoretical physicist Sabine Hossenfelder that we do not have free will: If you’ve read this site, you’ll know that my own views are pretty much the same as hers, at least about free will. We don’t have it, and the fundamental indeterminacy of quantum mechanics doesn’t give it to us either. Hossenfelder doesn’t pull any punches: “This means in a nutshell that the whole story of the universe in every single detail was determined already at the big bang. We are just watching it play out.”… QED! Jerry Coyne, “Sabine Hossenfelder says we don’t Read More ›
Why Pioneer Neurosurgeon Wilder Penfield Said the Mind Is More Than the Brain
He gave three lines of reasoning, based on brain surgery on over a thousand patientsMichael Egnor points out that Penfield offered three lines of evidence: His inability to stimulate intellectual thought during brain operations, the inability of seizures to cause intellectual thought, and his inability to stimulate the will. … So he concluded that the intellect and the will are not from the brain. Which is precisely what Aristotle said.

Michael Egnor: Is There Evidence for a Soul?
Some People Think and Speak with Only Half a Brain
A new study sheds light on how they do itA range of neuroscience research findings is more readily explained by assuming that some aspects of thought–– abstract intellectual thought and free will–– are immaterial.

Do We Actually Remember Everything?
Neuroscience evidence suggests that our real problem isn’t with remembering things but finding our memories when we need themOne of a pioneer neurosurgeon’s cases featured a patient who could, unaccountably, speak ancient Greek. The explanation was not occult but it was surely remarkable for what it shows about memory.

Four Researchers Whose Work Sheds Light on the Reality of the Mind
The brain can be cut in half, but the intellect and will cannot, says Michael Egnor. The intellect and will are metaphysically simpleNeurosurgeon Michael Egnor was featured in a short film as a supplement to the Science Uprising series. There, he mentions four researchers who have shed light on the non-material mind nature of our minds: Wilder Penfield (1891–1976): Some of the earliest evidence came from neurosurgeon Wilder Penfield, who was the pioneer in epilepsy surgery in the mid 20th century. Penfield operated on over a thousand epilepsy patients while they were awake (under local anesthesia), and he stimulated their brains with electrodes in order to identify epileptic regions for surgical resection. He carefully recorded their responses to stimulation. In his book Mystery of the Mind, (1975) Penfield noted: “When I have caused a conscious patient to move his hand by applying Read More ›
