OK, I’ve read your draft. 😊
Again: I’m not an expert in philosophy or psychology, so you’ve got to explain some things.

I mean, both to me here and now, and in the paper, so the readers can follow along

Sure, I’ll try my best.. ☺️

So, the “identity theory”: mental events are brain events                              

They argue it has to be the same brain process for each mental process.

So if I say that we both believe something, then we have to have the same brain processes …

… and that is nonsense of course 🙅🏻‍♀️                                                                 

Not only do different people have different brains, an individual brain also changes during your lifetime                                                       

That’s exactly the kind of information I needed!
Can you elaborate on that?.

Sure ! 

There are records of people with vastly different brains that still have mostly normal behavior and cognitive abilities                                                

Like the patients who have undergone hemispherectomy as children to cure certain forms of epilepsy.

I’m not a neurosurgeon, but I’ve had greek in highschool … 🤔 

“hemispherectomy” means something like “cutting away half the sphere”? 

 

Well done with the greek!👍🏻 That’s exactly what it means.                   

But it can’t mean removing half the brain, right? 😰

Oh yes it does! We can remove half the brain, generally in very young children, which then develop relatively normally.                   

I can’t believe this! Half the brain! 🧠 😳

Yes, and “relatively normally” means that most impairments are mainly due to the illness, not the surgery itself.                                                                                           

We can remove half a brain … with no ill effects? 🤨

Well, that does sound a bit too good to be true😊😊… but more or less, yes!

If the children are still young, the remaining hemisphere is adaptable enough to compensate for the missing half.

 

That’s … wow … that’s amazing!  ☺️🤗
And I see why that would be a problem for the theory ….

Yes! they think and feel just like everyone else, but with a completely different brain structure.                                             

So we can’t point out one-to-one correspondences with such large neurodiversity. 

That would be a problem indeed. Still, I saw there was another very similar position that could accommodate this …                                        

Could I first revise this part and then get back to you?

Sure thing! ☺️
