  So far we have considered extensional arguments against internalism. But there are also extensional arguments in favor of internalist theses. Setting aside peculiarly moral reasons, common sense suggests that ordinary practical reasons exhibit a high degree of agent-relativity. It is also natural to think that in at least many cases, different agents have different reasons because they want different things. If A desires chocolate ice cream, and B desires strawberry ice cream, then intuitively A has a reason to purchase the chocolate, and B has a reason to purchase the strawberry. Many have thought that the Humean Theory of Reasons is more than suggested by this sort of extensional data.
