Re Bramble, there’s no reason one has to have the moral belief that pain is bad to organize coalitions trying to avoid pain, based merely on it being disliked.
Re physicalism—well, I think the analogy doesn’t go through for a few reasons. First, it’s not even clear what it means to imagine that 2+2=5 without changing the definitions of words. But also, if we just reflect on what consciousness is, it’s very clear that we could imagine every particle moving the same way but there not being consciousness. I agree you have to deny that if you’re a physicalist—that’s one good reason not to be a physicalist.
Re the challenge that no realist has addressed—Enoch addresses it in that article. He also says they haven’t addressed the challenge that way, but the responses they gave still apply—eg the Parfit response to evolutionary debunking.
