Abstract

Is Kant’s "Formula of the End in Itself" overly demanding? In addressing this question, I sketch a conception of co-obligation, that is, a sort of moral requirement that holds, not of persons distributively, but of persons collectively. I then raise a problem of devolution: How does a co-obligation for all persons devolve upon me? For instance, given that we must maximize happiness, it does not seem to follow that I must always act so as to maximize happiness. In partial answer to this problem, I claim that some Kantian duties do stem from co-obligations. But this claim has as a crucial assumption the following conjecture: The "Formula of the End in Itself" is to be read as implying that we must treat each person as an end and not simply as a means.
