The opening paragraphs of Egnor's essay call this view into serious question. He writes:
I watched the CAT scan images appear on the screen, one by one. The baby’s head was mostly empty. There were only thin slivers of brain – a bit of brain tissue at the base of the skull, and a thin rim around the edges. The rest was water.Well, if materialism is true it's hard to see how it could be possible, but if materialism is false then there might be an explanation that includes a soul or mind that's somehow integrated with the brain but which is nevertheless not ultimately explicable in terms of the material stuff that makes us up.
Her parents had feared this. We had seen it on the prenatal ultrasound; the CAT scan, hours after birth, was much more accurate. Katie looked like a normal newborn, but she had little chance at a normal life.
She had a fraternal-twin sister in the incubator next to her. But Katie only had a third of the brain that her sister had. I explained all of this to her family, trying to keep alive a flicker of hope for their daughter.
I cared for Katie as she grew up. At every stage of Katie’s life so far, she has excelled. She sat and talked and walked earlier than her sister. She’s made the honor roll. She will soon graduate high school.
I’ve had other patients whose brains fell far short of their minds. Maria had only two-thirds of a brain. She needed a couple of operations to drain fluid, but she thrives. She just finished her master’s degree in English literature, and is a published musician.
Jesse was born with a head shaped like a football and half-full of water – doctors told his mother to let him die at birth. She disobeyed. He is a normal happy middle-schooler, loves sports, and wears his hair long.
Some people with deficient brains are profoundly handicapped. But not all are. I’ve treated and cared for scores of kids who grow up with brains that are deficient but minds that thrive. How is this possible?
Egnor goes on in his essay to show that mental processes like thoughts and sensations cannot be reduced to physical structures and also why the materialist denial of human free will is almost certainly wrong.
He offers the sorts of arguments that are making it very difficult nowadays to be a consistent materialist. Indeed, some materialists are finding it so difficult to explain phenomena like human consciousness solely in terms of the material brain that they've even taken to denying that consciousness exists, but this seems like madness. After all, doesn't one have to be conscious in order to think about whether consciousness exists?
Evidently, some philosophers will go to any lengths, no matter how bizarre, to avoid having to accept any idea that may lead to the existence of anything that's consistent with a theistic worldview.
Egnor concludes his column with this:
There is a part of Katie’s mind that is not her brain. She is more than that. She can reason and she can choose. There is a part of her that is immaterial.... There is a part of Katie that didn’t show up on those CAT scans when she was born.
Katie, like you and me, has a soul.
