Thanks for this Michael. I don’t have a proper reply to it right now, because it raises so many complicated issues that I haven’t thought through yet (though briefly, I don’t actually think same brain guarantees same pain when embedded in different bodies/​environments). But your right that differences in trade-offs between best pleasure and worst pain probably sink the naive normalization strategy I was suggesting. I’d need to know more maths than I do to have a sense of whether it is fixable. Someone suggested to me that some of the ideas in this book (which I haven’t read yet) would help: https://​​philpapers.org/​​rec/​​MACMU-3
