ABSTRACT
Parfi t suggested that the self-interest theory’s hybrid position may be unstable and indefensible. In particular, he claimed that the strongest arguments that the self-interest theory might muster in opposition to the present-aim theory, against relativizing with respect to place and time, might analogously tell against relativizing with respect to individuals, and so may carry one from the present-aim theory, beyond the self-interest theory, and all the way to the neutralist position. Likewise, Parfi t suggested, the strongest arguments that the self-interest theory might muster in opposition to the neutralist position, against being neutral with respect to people , might analogously tell against being neutral with respect to place and time, and so may carry one from the neutralist position, beyond the self-interest theory, and all the way to the present-aim theory.
