Against Welfare Subjectivism

Subjectivism about welfare is the view that something is basically good (bad) for you if and only if, and to the extent that, you have the right kind of favorable (disfavorable) attitude toward it under the right conditions. I make a presumptive case for the falsity of subjectivism by arguing against nearly every extant version of the view. My arguments share a common theme: theories of welfare should be tested for what they imply about newborn infants. Even if a theory is intended to apply only to adults, the fact that it is false of newborns may give us sufficient reason to reject it.
