ABSTRACT
Parfi t’s argument against the Self-Interest Theory suggests that rationality requires that we treat persons, places, and times the same in certain key respects, and, in particular, that if we should be neutral with respect to one, we should also be neutral with respect to the others. Reasoning along similar lines, it might seem natural to assume that if we accept a dominance principle with respect to one of these categories, then we should also accept a similar dominance principle with respect to the other categories. Consider, for example, the following three dominance principles regarding utility.
