The SEP says that preferences cannot be aggregated without additional constraints on how the aggregation is to be done, and the end result changes depending on things like the order of aggregation, so these additional constraints take on the quality of arbitrariness. How does CEV get around that problem?
From the CEV paper:
...Different classes of satisfactory initial definitions may fall into different selfconsistent attractors for optimal definitions of volition. Or they may all converge to essentially the same endpoint. A CEV might survey the “space” of initial dynamics and self-consistent final dynamics, looking to see if one alternative obviously stands out as best; extrapolating the opinions humane philosophers might have of that space. But if there are multiple, self-consistent, satisficing endpoints, each of them optimal under their own criterion—oka
