  In response, Humeans can observe that in ordinary cases agents want pleasure, and that thereby HTR can accommodate such reasons. This line of objection needs a case in which an agent has a reason to do not just something that she does not already desire to do, but something that would not serve any desire whatsoever that she already has. Since any given action may serve many different possible desires, and agents who do not desire (e.g.) pleasure are rare and peculiar, it is difficult to control for these kinds of factors. Externalists can claim that an agent would have a reason to do what is pleasurable even in the absence of any such general desire, but this is something that an internalist may be able to deny without absurdity—although here intuitions seem to differ radically.
