The compatibility of objective goods perfectionism and value pluralism also can be established. One need only assume that some perfectionist goods are either roughly equal or incommensurable in value (Finnis 1980; Raz 1986). Friendship and understanding, for example, may both be perfectionist goods, but they may not be comparable in a way that allows us to rank lives that realize these goods to different degrees. More generally, perfectionist goods may be combinable in different proportions, yielding a range of different types of life that are valuable and worthy of pursuit. The adjective “perfect” when applied to a human life suggests one that is maximally good or excellent, but if goods conflict and are incomparable, then a plurality of different types of life may have a title to that designation.
