Thanks! That’s a really interesting thought. I hadn’t thought of that possibility—I’ve been working on the assumption that they’re not reducible—but now that you mention it, I don’t have very strong intuitions about whether it seems more or less likely than there being two dimensions “at bottom”.
One intuition against is that it seems a bit weirdly discrete to suppose that a “hedonic atom” can just be +1, 0, or −1. But I guess there’s some discreteness at bottom with literal atoms (or perhaps a better analogy would be electrical charge) as well...
