Abstract
We often treat our basic, unmotivated desires as reason-giving: you’re thirsty and take yourself to have a reason to walk to the drinking fountain; you care intrinsically about your young daughter and take yourself to have a reason to feed and clothe her. We think these desires generate normative practical reasons. But are there basic desires that don’t? It might seem so, for we sometimes find ourselves impelled to do some very strange, and some very awful, things. For example, would a loving mother with a violent impulse thereby come to have a reason to harm her beloved child? Let’s grant, for the sake of argument, that there are basic desires, such as the mother’s, that fail to generate reasons. Can a subjectivist, a theorist in the Humean tradition, accept this thesis? Against the historical grain, I argue yes. I frame my discussion in terms of solving a puzzle in Harry Frankfurt’s subjectivist theory of rational agency and appeal to the concept of a personal ideal to reveal how a subjectivist, a follower of Hume, can countenance the existence of “rationally impotent basic desires.”
