  W.D. Ross (138) considered two worlds that are equals both hedonically and in character terms. In one world, the virtuous have the pleasure and the vicious have the pain, while in the other the vicious have the pleasure and the virtuous have the pain. To help secure across all plausible accounts of the nature of pleasure the ‘equality of pleasure’ that is central to this case comparison, suppose that in each world the same pleasures are taken in the same objects. Pleasure is equal across these two worlds, but Ross argues that the well-matched world is better than the mis-matched world. If he is right, then this is a case of ‘same pleasure, different value’, and thereby also a case in which difference of pleasure is not necessary for difference of value.
