What Should the Desire Theorist Say About Ill-Being?

Both proponents and critics of the desire theory of welfare have narrowly focused on the positive side of the theory while virtually ignoring its negative side. On the positive side, the desire theorist says that getting what you want is good for you. But what should the desire theorist say is bad for you? A common and plausible-sounding answer is that if getting what you want is good for you, then surely not getting what you want is bad for you. I argue that this answer is a mistake that would commit desire theorists to a claim that is implausible by their own lights, namely that a state of affairs could be bad for you even if you were not at all bothered by it. The desire theorist should instead say that getting what you are averse to is bad for you. If desire satisfaction is good for you, then aversion satisfaction, not desire frustration, is bad for you.
