In a very interesting interview on the unlikelihood that Sci-Fi style artificial intelligence (AI) is coming soon, or even possible, computer scientist Noel Sharkey says why he thinks that AI is a dangerous dream –
I’m an empirical kind of guy, and there is just no evidence of an artificial toehold in sentience. It is often forgotten that the idea of mind or brain as computational is merely an assumption, not a truth. When I point this out to “believers” in the computational theory of mind, some of their arguments are almost religious. They say, “What else could there be? Do you think mind is supernatural?” But accepting mind as a physical entity does not tell us what kind of physical entity it is. It could be a physical system that cannot be recreated by a computer.
Of course, materialists have a very hard time accepting that anything of non-material nature exists, anything that is not some mere arrangement of matter and energy, space and time. What the materialist approach fails to explain is that this theory is itself a non-material thing. What is the materialist nature of an idea? Calling it a mere brain state, even a brain state that is shared by others, forces us into the notion that a “brain state” is about something. Yet the materialists have mostly asserted that what we call consciousness is mere “noise in the system.” How to account for “brain states” that are about other “brain states” which are attempts to account for the existence of other “brain states”? One is tempted to take seriously the idea that maybe the minds of materialists are just “noise in the system.”
(Editorial comment in 2023: For our purposes here, don’t confuse large language models like ChatGPT with actual AI in sense discussed above. ChatGPT is not sentient, and will “tell” you so. No current AI whose existence is public is “sentient”, which begs the question of what is meant by the word “intelligence” in “artificial intelligence.” This is probably because no one has any real concept of just what consciousness or sentience is, how it works, what produces it, etc. Large language models, as neural-net systems that have been trained with enormous amounts of linguistic usage as data, boil down to the management of lists of billions of possible verbal formulations, and the assignment of probabilities to them. Sentience is something quite a bit more mysterious than a large list with assigned probabilities.)
In his book, The Spiritual Brain, neuroscientist Mario Beauregard adduces the evidence for a non-material mind that is related to but independent of the physical brain.
In the book, Beauregard makes short work of claims of a “God gene” or a “God spot” in the brain, something that would provide a false sense of transcendental experience that could be falsely attributed to God by the gullible. He asks some very interesting questions about the placebo effect, and what that effect suggests about the relationships of mind, brain and body. His discussion of the small but persistently measurable PSI effect is very interesting, and refreshing to read from a scientist. Especially interesting is the discussion about the implications of psycho-therapeutic models that involve teaching people to think different ways, essentially using “mind” to affect “brain,” producing measurable physical effects by changing ideas held by a person. Beauregard’s work in using functional MRI to study the brains of meditating Carmelite nuns is very interesting, and well worth reading.
You may have the impression that someday science will explain the mind in physical terms. This is certainly the notion that materialist neuroscientists would like to create in the public mind, yet another form of promissory materialism.
The problem, of course, is that a promise of future theoretical success is a non-material idea flowing from a non-material motivation to defend a non-material perspective about the nature of things. It seems an impossible task.
Think of it as analogous to trying to write an essay on the topic, “Why there is no such thing as an essay.” (Coming up next: “Why there is no such thing as a question…. or an answer.”)
The amazing thing about the human mind is not that it has a non-material aspect. It is that it has a physical aspect. After all, the human mind is an echo or image of the non-material Mind behind everything. Of course it has a non-material aspect. The amazing thing is that the Creator made a unique integration of mind, brain and body, one that seems to have been designed specifically to allow free moral choice in a physical universe that is of non-physical origin, one characterized as much by quantum uncertainty, which makes free will possible, as by obvious cause and effect relationships.
