Abstract  Neo-Humean instrumentalists hold that anagent''s reasons for acting are grounded in theagent''s desires. Numerous objections have beenleveled against this view, but the mostcompelling concerns the problem of ``aliendesires'''' – desires with which the agent doesnot identify. The standard version ofneo-Humeanism holds that these desires, likeany others, generate reasons for acting. Avariant of neo-Humeanism that grounds anagent''s reasons on her values, rather than allof her desires, avoids this implication, but atthe cost of denying that we have reasons to acton innocent whims. A version of neo-Humeanismthat holds that an agent has reason to satisfyall of her desires that are not in conflictwith her values appears to allow us to grantthe reason-giving force of innocent whims whiledenying the reason-giving force of alien desires.
