How Split-Brain Surgery Underlines the Unity of Consciousness

At one time, some thought that if the brain were split, consciousness would be too, but that did not turn out to be true

In the third podcast of a series, “Unity of Consciousness,” Walter Bradley Center director Robert J. Marks interviews Angus Menuge, professor and chair of philosophy at Concordia University, on unique features of human consciousness. They started with the fact that our experiences are a unity despite being scattered across many brain regions. But it’s a remarkable fact that our consciousness remains single even when our brains are split in half: https://episodes.castos.com/mindmatters/Angus-Menuge-Episode-3-rev1.mp3 This portion begins at 03:04 min. A partial transcript, Show Notes, and Additional Resources follow. Robert J. Marks: Let’s talk about the split brain operation where a neurosurgeon goes in and separates the right and left hemispheres. As I understand it, the signal for the epileptic fits starts on Read More ›

Does Split-brain Surgery Show That We Have No Real Identity?

A prominent philosopher built his career arguing against the existence of personal identity

One of the most bizarre consequences of the modernist materialist conception of human beings is the notion that personal identity is not real or not continuous. This view is, of course, contrary in every way to the lived experience of each of us. Like everyone else, I am the same person I was as a child, and the same person I will be a moment before my death. I am me, and I am no other. Of course, at different times of my life I have had different memories, experiences, and perceptions, but it is the same I (the only I) that has them. This is so fundamental to reality that it seems beyond question. It is not even clear Read More ›

If Your Brain Were Cut in Half, Would You Still Be One Person?

Yes, with minor disabilities. Roger Sperry’s split-brain research convinced him that the mind and free will are real

The true significance of the split-brain experiments goes far beyond the significance of the lateralization of the brain; your essential unity also points to the immaterial nature of the mind.

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

Can Buzzwords About “Neural Networks” Save Materialist Neuroscience?

No. Experiments that support an immaterial consciousness often involve split or massively damaged neural networks

The attribution of abstract thought to the material brain is philosophical and logical nonsense and has been repeatedly discredited by the best neuroscience over the past century.
