ABSTRACT
In this chapter I argue that metaethically objective moral theories must be impartial, that is, they must treat morally like persons in morally like ways, and not count special relationships with individuals as justifying treating those persons better than one treats others. In section 1, I provide two examples to which I shall refer. In section 2, I provide the main argument. In section 3, I compare partiality and egoism. In section 4, I argue that the impartiality that impartial theories require must be aggregative, not local.
