Why, as a Neurosurgeon, I Believe in Free Will

The spiritual aspect of the human soul, sadly, leaves its signature in epilepsy

In 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…

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 neuroscience

Evolutionary 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…

Neuroscience Can’t Dismiss Near Death Experiences

It’s sobering to note that neuroscience has utterly failed to explain how the brain and mind relate

Despite claims, NDEs are radically different from any mental experience caused by brain impairment.

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 patients

Michael 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.

Yes, Split Brains Are Weird, But Not the Way You Think

Scientists who dismiss consciousness and free will ignore the fact that the higher faculties of the mind cannot be split even by splitting the brain in half

Patients after split-brain surgery are not split people. They feel the same, act the same, and think the same, for all intents and purposes. Materialists like Jerry Coyne focus on subtle differences and distort the big picture.

Some People Think and Speak with Only Half a Brain

A new study sheds light on how they do it

A range of neuroscience research findings is more readily explained by assuming that some aspects of thought–– abstract intellectual thought and free will–– are immaterial.

A Materialist Neuroscientist Continues the Argument with Himself

On the topic of “intellectual seizures,” he seems committed to both points of view

I assert that intellectual seizures do not exist. Dr. Ali asserts that they do exist and that they do not. The difference between their existence and their non-existence seems to be Dr. Ali’s rhetorical needs of the moment.

Do “forced thinking” seizures show that abstract thought is a material thing?

Epilepsy suppresses abstract thought, it does not evoke it
It’s worth noting that Wilder Penfield, (with Herbert Jasper, his neurologist colleague), was one of the first doctors to characterize forced thinking seizures and he asserted that there are no intellectual seizures. He understood that forced thinking seizures are not seizures of the intellect. Read More ›

Do Epileptic Seizures Cause Abstract Thoughts?

A psychiatrist argues that “intellectual seizures” can occur

Seizures never evoke abstract thought. That is, if a seizure causes you to think about a triangle, it always causes you to imagine a particular triangle, not to define triangles abstractly.
