I'd have to agree with Chomsky. It would be tremendously difficult to contort ones thinking greatly enough to be able to explain things like why those who suffer total facial paralysis lose the ability to feel anger, then the ability to recall what feeling anger was like, then the ability to recognize anger in other people and other similar body-mind interactions while still holding on to some idea of there being a "non-physical mind" in the manner usually proposed. In my own opinion, 'mind' is a property, not a thing. You need a thing to exhibit the property, just like you can't simply have a box full of "hot" without some material exhibiting it, and consciousness is a property we're sure human brains can have (by definition if nothing else). Going beyond that is difficult, and you're guaranteed to fail if the first thing you do is seek to eliminate all the material while trying to retain the property.

I am unaware of what Newton wrote to 'demolish the body', but I wonder if it is related to chaos theory, complexity, and similar intractable interconnections that limit pure reductionist mechanical understandings of things. We don't quite know how to bridge the gap from "we know we can not discount even the smallest detail without predictions deviating" to "yet we can predict complex systems with reductionist views and attain great accuracy if we restrict how much accuracy we want." Those two things are both true, and seem to be in direct conflict with one another. Should we ever be able to bridge that gap, it would probably herald a new golden age and be a far more important development than anything that has come before.

"to be able to explain things like why those who suffer total facial paralysis lose the ability to feel anger, then the ability to recall what feeling anger was like, then the ability to recognize anger in other people"

I have never heard of this before and I can find no information about this on the internet. I know people who have had facial paralysis (my uncle had MND and lost everything) and they were really really angry (at times) and I do not remembering that they lost empathy when I was interacting with them. My uncle struggled to express himself when using the eye tracker, but the last time I saw him he made jokes and asked me about my daughter, I think that that's empathic.

I originally read about the phenomenon years ago in a (audio)book, but I cannot recall which one. It may have been one of Oliver Sacks' books, or part of a course from The Teaching Company or the Great Courses Plus. They discussed related research that claimed to have found strong evidence for depression in patients paralyzed from the neck down which was greater than the life changes and such could account for. I was never clear on how they could possibly manage to separate the things to be able to make such a claim and the facial paralysis emotional involvement seemed to make much more sense. There is a great deal of evidence already linking facial involvement to emotion, such as the classic study where participants held a pencil in their teeth, which causes an involuntary 'smile', lessening the negative emotional response when watching sad videos, so it seemed to be reasonable.

It's not that the people become un-empathetic, but literally when shown a photograph of a face expressing the emotion of anger, they can not identify that it is the emotion being displayed. That is the most extreme extent that takes the longest to manifest as I understand it. If a person told them "I am angry" or there were other outward displays (raised voice, etc), I don't doubt they would deal with it appropriately. Issues with recognizing emotions in others based on facial expressions are not all that rare. It is very commonly found in men who abuse others that they are incapable of recognizing the expression of fear in the face of those they are abusing.

I managed to find one related study that you might find interesting reading, though I hope to find better resources eventually: https://jamanetwork.com/journals/jamafacialplasticsurgery/fu...

My personal view is that this paper is probably closest to being correct about the nature of emotion and the body: https://www.cell.com/trends/cognitive-sciences/fulltext/S136...
