Ah wait, did your first comment always say “similar”? No worries if not (I often edit stuff just after posting!) but if so, I must have missed it—apologies for just pointing out that they were different points and not addressing whether they are sufficiently similar.
But they do seem like significantly different hypotheses to me. The reason is that it seems like the arguments presented against many experiences in a single brain can convince me that there is probably (something like) a single, highly “integrative” field of hedonic intensities, just as I don’t doubt that there is a single visual processing system behind my single visual field, and yet leave me fully convinced that both fields can come in different sizes, so that one brain can have higher welfare capacity than another for size reasons.
Thanks for the second comment though! It’s interesting, and to my mind more directly relevant, in that it offers reasons to doubt the idea that hedonic intensities are spread across locations at all. They move me a bit, but I’m still mostly left thinking - Re 1, we don’t need to appeal to scientific evidence about whether it’s possible to have different amounts of, say, pain in different parts of the phenomenal field. It happens all the time that we feel pain in one hand but not the other. If that’s somehow an illusion, it’s the illusion that needs a lot of scientific evidence to debunk. - Re 2, it’s not clear why we would have evolved to create valence (or experience) at all in the first place, so in some sense the fact that it would evidently be more efficient to have less of it doesn’t help here. But assuming that valence evolved to motivate us in adaptive ways, it doesn’t seem like such a stretch to me to say that forming the feeling “my hand is on fire and it in particular hurts” shapes our motivations in the right direction more effectively than forming the feeling “my hand is on fire and I’ve just started feeling bad overall for some reason”, and that this is worth whatever costs come with producing a field of valences. - Re 3, the proposal I call (iii*) and try to defend is “that the welfare of a whole experience is, or at least monotonically incorporates, some monotonic aggregation of the hedonic intensities felt in these different parts of the phenomenal field” (emphasis added). I put in the “incorporates” because I don’t mean to take a stand on whether there are also things that contribute to welfare that don’t correspond to particular locations in the phenomenal field, like perhaps the social pains you mention. I just find it hard to deny from first-hand experience that there are some “location-dependent” pains; and if so, I would think that these can scale with “size”.

There’s a good chance I edited that in, but I don’t remember for sure.

I don’t think this is an illusion. However, my understanding of the literature is that pain has 3 components: sensory, affective (unpleasantness) and motivational (aversive desire, motivational salience, how it pulls attention). The sensory component is location-specific and like a field. The affective component seems not like a field, imo, but this is not settled, AFAIK. The motivational component is (in part) the pull of your attention to the motivationally salient parts of your sensory field. It selects and amplifies signals from your sensory field.
it doesn’t seem like such a stretch to me to say that forming the feeling “my hand is on fire and it in particular hurts” shapes our motivations in the right direction more effectively than forming the feeling “my hand is on fire and I’ve just started feeling bad overall for some reason”, and that this is worth whatever costs come with producing a field of valences.
I think the mechanism of motivational salience could already account for this. You don’t need a field of valences, just for your attention to be pulled to the right parts of your sensory field.
