Neuroscientist: Consciousness is not a neural phenomenon

Spread the love
Alva Noe/J. Walsh

From Alva Noe at NPR, we learn:

For some time now, I’ve been skeptical about the neuroscience of consciousness. Not so much because I doubt that consciousness is affected by neural states and processes, but because of the persistent tendency on the part of some neuroscientists to think of consciousness itself as a neural phenomenon.

Nothing epitomizes this tendency better than Francis Crick’s famous claim — he called it his “astonishing hypothesis” — that you are your brain. At an interdisciplinary conference at Brown not so long ago, I heard a prominent neuroscientist blandly assert, as if voicing well-established scientific fact, that thoughts, feelings and beliefs are specific constellations of matter that are located (as it happens) inside the head. My own view — I laid this out in a book I wrote a few years back called Out of Our Heads — is that the brain is only part of the story, and that we can only begin to understand how the brain makes us consciousness by realizing that brain functions only in the setting of our bodies and our broader environmental (including our social and cultural) situation. The skull is not a magical membrane, my late collaborator, friend and teacher Susan Hurley used to say. And there is no reason to think the processes supporting consciousness are confined to what happens only on one side (the inside) of that boundary.

Taken seriously, these are fighting words.

But does Noe understand what he is saying? That there can be an immaterial mind that is not exclusively what neurons do? Guy better watch his back.

Noe is introducing a new Oxford journal Neuroscience of Consciousness. Its editor, Anil Seth, observes correctly,

It’s tricky to come up with a rigorous scientific definition of consciousness which enjoys a broad consensus. On the other hand, we are all familiar with what consciousness is. Put simply, for a conscious organism, there is ‘something it is like’ to be that organism. Put another way, consciousness is lost when falling into a dreamless sleep (or undergoing general anaesthesia), and it is what returns the next morning on waking up (or coming round). More generally, consciousness implies a continuous (but interruptible) stream of phenomenal senses or experiences – a technicolour, multimodal, fully immersive and wholly personalised movie, playing to an audience of one.

And, Noe adds,

It’s worth noting that this characterization of what it is for an organism to be conscious — that there is something that it is like to be that organism — was first advanced in the 70s by the philosopher Thomas Nagel.

I don’t intend this observation as a criticism. … More.

No, not a criticism, but a warning.

And Noe himself, who seems comfortable with naturalist premises except where they don’t make sense, had better beware the “punks, bullies, and hangers-on” that, in the words of computer science prof David Gelernter, formed a lynch mob out to get Nagel.

That’s because, in Mind & Cosmos, Nagel had doubted the all-sufficiency of the punks’ religion, Darwinism. He even admired Steve Meyers influential Darwin’s Doubt, on the Cambrian explosion.

Form experience, a word of advice to Noe and Seth: Don’t appease and don’t back down. It amounts to saying you don’t think your work is actually science. That’s all they want and need from you, and precisely what you can’t afford to give. And those who soldier on and don;t give in are, aswe all know, making progress.

Would we give up naturalism to solve the hard problem of consciousness?

Note: Noe is author of Out of Our Heads: Why You Are Not Your Brain, and Other Lessons from the Biology of Consciousness (2009). See also: News’ review of Out of Our Heads:

The greatest strength of Out of Our Heads is the way in which Noë confronts the true significance of research findings that are often obscured for the public by materialist bias in the popular science media. For example, he notes, “It is disturbing to learn that so far there are no theoretically satisfying or practically reliable criteria for deciding when a person with brain injury is conscious or not.” It certainly is disturbing if you followed the Terry Schiavo case, or have watched the relentless advance of euthanasia legislation (though Noë avoids that issue).

He does discuss the implications of remarkable neuroscience studies like those of the late engineer and physiologist Paul Bach-y-Rita, who showed that blind people could be taught to “see” using their tactile sensations … More.

    Maybe we can use acceptance of this scientific fact as a litmus test for qualifying candidates for all positions of employment in the public sector including teachers, politicians, doctors and especially positions at universities. To pass the test, they would have to confess something like: “I don’t “have” a soul, I AM a soul. I “have” a body”

    This is all very interesting. I’m surprised Alva Noe still has a job. I’m having trouble believing this story. Did a revolution happen in the neuroscience community while I was not looking?

    How did this thread become the second most popular article posted in the last 30 days even though it has only 3 comments, including this one? Is there something I’m missing?

    It’s still a big mystery how materialists manage to be so succesful in establishing materialism.

    I mean beauty for example, it is an opinion what is beautiful. An opinion is not a fact. So we have things which are real, but the reality of them is not a fact, like beauty.

    So it would obviously be totally useless to try to make a worldview, materialism, in which everything is fact, because then you leave no room for opinion, like beauty.

    How can anybody be so stupid to exclude subjectivity, and how can they have success with that view? It is just so tragic to see people, evolutionists, argue such complete nonsense, and then winning, and being congratulated for it by many people. I also find it surreal.
