Sections 1.4 and 8.5 in my book deal directly with the first issue you raise. Also see Chapter 3, “Creating Happiness at the Price of Suffering Is Wrong”, for various arguments against a moral symmetry between pleasure and suffering. But many chapters in the first part of the book deal with this.
Empirically, I think it’s pretty clear that most people are willing to trade off pleasure and pain for themselves.
I say a good deal about this in Chapter 2. I also discuss the moral relevance of such intrapersonal claims in section 3.2, “Intra- and Interpersonal Claims”.
Thanks for your comment, George.
