Another reason for rejecting the answer we are considering is that it threatens to underwrite an unattractive relativism. Different societies may differ considerably in their extant moral beliefs. So a way of assessing proposed codes that considers the costs of getting people already committed to some other code will end up having to countenance different transition costs to get to the same code. For example, the transition costs to a non-racist code are much more from an already accepted racist code than from an already accepted non-racist one. Formulating rule-consequentialism so that it endorses the same code for 1960s Michigan as for 1960s Mississippi is desirable.
