There is no "I" in "You"

[Thumpalumpacus]

If you put person A's memories and experiences in person B, then you are pretty much erasing both A and B and getting person C, because the mind, body and everything else together forms the unique individual.

Person A might disagree with that assessment.

Would A be wrong?

My physique informs my mentality. For instance, I have a debilitating bone disease in my hip that imparts chronic pain. In the thirty+ months since it's cropped up, I've grown mentally in the act of dealing with said pain; I've learnt how to cope with it, and found mental strength in making adjustments -- or not making adjustments -- in my life to cope with it.

I think the assumption that body does not affect mind is just that -- an assumption, and not borne out by experience. Thought experiments are great, I'm all for 'em -- but actual experiences trump thought experiments, for my money.

I am person A in the sense that my body has changed.
