 We broached the first formal argument in section 4. There we noted that not every norm could be integrated with self-interested concerns into an all-things-considered set of judgments that satisfied the formal conditions of a preference. To succeed, the strategy of incorporation must show that each of the agent’s moral “tastes” or concerns have a normative structure that is compatible with her underlying, self-interested preferences. The strategy of incorporation thus might fail because of the structure of the obligations that the agent endorses.
