...How many studies into physical interference with the brain altering behavior do you need to get this isn't the case? It's multiple big businesses, for crying out loud!
And again, this is typical of materialist arguments. 'My position is the only possible interpretation of evidence. If you disagree with my interpretation, you disagree with evidence!'
No.
No it is not.
The brain, along with the rest of the nervous system, is clearly the physiological control system for the body. There's no real doubt on that. Sensory intake, interpretation, memory storage and recall, all of these things clearly have a physical functionality in the brain.
The question is not 'is the brain used for this?' The question is 'is the brain using itself, or being used?'
The brain as the 'pilot's seat' or 'interface and control system' for the soul is a perfectly reasonable interpretation of the evidence, so long as you aren't a dogmatic materialist. It's completely coherent with how brain abnormalities, damage, and treatments, affect a person's ability to function in this world.
What materialists can't explain about how brute mechanistic functions would create, and thus the problem the worldview shares with the concept of sapient AI simply 'emerging' from computer systems, an emergent phenomena as abstract as conscious thought.
On top of all the other absurdities and blatant falsehoods of evolutionary theory, the idea that the incredible resources needed to create something as sophisticated as human cognition, through a purely mechanical computing system, would be advantageous for
millions upon millions of years when it's incomplete and non-functional, yet depriving the 'evolving' organism of the resources needed to support it for iterative generation after generation of random chance just
happening to drop element after element of the system into place until it
finally is complete enough to perform an actually useful function, it's beyond absurd.
But then, irreducible complexity has been the kryptonite of the cult of materialism for decades. It still defeats them at blood clotting, sexual reproduction, and abiogenesis itself, so why would such fanatics be any more rational about applying it to the brain and conscious thought?
Maybe if people start making biological computers, particularly out of lab-grown human brain tissue, we will some day get a sapient AI.
It's never happening with transistor-based computing. That's not how physics work.
