Part 3
Testing materialismNow, let’s consider Owen’s findings in light of Dr. Novella’s specific predictions about mind/brain correlation. The study actually addresses three of Dr. Novella’s predictions:
2.As brain function is altered, the mind will be altered.
3.If the brain is damaged, then mental function will be damaged.
5.We will be able to correlate brain activity with mental activity – no matter how we choose to look at it.
Dualism predicts:
2.As brain function is altered, the mind will not necessarily be altered
3.If the brain is damaged, then mental function will not necessarily be damaged
5.We will not always be able to correlate brain activity with mental activity – no matter how we choose to look at it.
Owen’s evidence correlates much more closely with the predictions of dualism than it does with the predictions of materialism. Consider each prediction:
Strict materialism: As brain function is altered, the mind will be altered
Dualism: As brain function is altered, the mind will not necessarily be altered
Dr. Owen’s evidence is in accordance with the dualist prediction. The most parsimonious conclusion was that she was conscious, despite a diagnosis, based on traditional neurological examination, EEG, and neuroimaging, of persistent vegetative state, which is defined as the absence of consciousness. This panoply of neurological tests predicted different — and incompatible — things. Standard brain tests indicated that she had no mind. fMRI testing indicated that her mind was indistinguishable from that of a normal person. Recall that Dr. Novella insists that “every single prediction” of materialism has been verified. That’s not possible with tests that yield contradictory results.
Strict materialism: If the brain is damaged, then mental function will be damaged.
Dualism: If the brain is damaged, then mental function will not necessarily be damaged
Again, Dr. Owen’s evidence is more consistent with dualism than it is with materialism. The patient’s brain was profoundly damaged, but her fMRI correlated with normal conscious thought.
Strict materialism: We will be able to correlate brain activity with mental activity – no matter how we choose to look at it.
Dualism: We will not always be able to correlate brain activity with mental activity – no matter how we choose to look at it.
Dr. Novella’s claim is directly falsified by Owen’s work, because different studies of brain activity gave opposite conclusions about the patient’s mental activity. Dr. Owen’s findings are clearly more consistent with the dualist prediction than with the strict materialist prediction. The central finding of the Cambridge researchers is that correlation between brain activity and mental activity can be quite nebulous, and the findings can even be completely contradictory. fMRI suggested the woman was fully conscious; all other tests suggested that she was in persistent vegetative state, without any consciousness at all.
Conclusion Strict materialism predicts that mental function will always correlate with brain function, because mental function is the same thing as brain function. Dualism predicts that mental function and brain function won’t always correlate, because mental function isn’t the same thing as brain function. The Cambridge findings are more consistent with the dualist prediction than with the strict materialist prediction. That is, in a sense, why the paper received so much attention; it suggested that mental function may not be linked to brain function in a strict cause-and-effect relationship.
So is it reasonable to conclude that Owen’s findings prove dualism? Of course not. Science doesn’t work that way. Scientific theories prevail by preponderance of evidence and by carefully considered inferences, not by “proof” or by validation of “every single prediction.” Hyperbole is the currency of hucksters, not scientists. But the growing body of scientific evidence, which is consistent with my experience as a neurosurgeon for 23 years, suggests that the strict materialist theory of the mind is simplistic and probably wrong. There’s scientific evidence that justifies the inference that there is more to the mind than the brain.
Dr. Novella again:
The materialist hypothesis - that the brain causes consciousness - has made a number of predictions, and every single prediction has been validated. Every single question that can be answered scientifically - with observation and evidence - that takes the form: “If the brain causes the mind the…” has been resolved in favor of that hypothesis… [w]hat Egnor has not done is counter my claim that all predictions made by the materialist hypothesis have been validated. If he wishes to persist in his claims, then I openly challenge Egnor to name one prediction of strict materialism that has been falsified. To be clear, that means one positive prediction for materialism where the evidence falsifies strict materialism. This does not mean evidence we do not currently have, but evidence against materialism or for dualism. I maintain that such evidence does not exist – not one bit…
…Prove me wrong, Egnor…
