Abstract
Welfare subjectivists face a dilemma. On the one hand, traditional subjectivist theories—such as the desire-fulfillment theory—are too permissive to account for the well-being of typical mature human beings. On the other hand, more “refined” theories—such as the life-satisfaction theory—are too restrictive to account for the well-being of various welfare subjects, including newborns, those with profound cognitive impairments, or non-human animals. This paper examines a class of welfare subjectivism that addresses this dilemma with sensitivity to the diversity in welfare subjects. First, the most-sophisticated-attitude view (MSA) is introduced. MSA holds that an object, x, is good for a subject, S, in proportion to the strength of S’s pro-attitude towards x if and only if the pro-attitude at issue is S’s most sophisticated type. Typically, the well-being of typical mature human beings is assessed in terms of one’s authentic whole-life satisfaction, whereas that of human newborns is assessed in terms of something less sophisticated such as pleasure. MSA offers the rationale for this difference based on an underexplored version of perfectionism: procedural perfectionism. Next, provided that MSA may involve an implausibly strong claim, this paper examines two moderate variations of MSA that accept the partial relevance of less sophisticated types of valenced attitude. Finally, it is illustrated how MSA and its variations have plausible implications regarding the well-being of enhanced or dis-enhanced people.
