 Embedded instrumentalist theories of health have an obvious appeal. Once we argue that health involves judgments about how well a person’s life is going, we need a way to evaluate that, and an immediately attractive idea is that someone’s life goes well if they can achieve their ambitions or satisfy their goals. An apparent difficulty, however, is that much the same terrain is covered by theories of well-being, and while people think that being healthy is important to their well-being (Eid and Larsen 2007), they do not identify the two. Rather, they think of health as a component of well-being or a contributor to it.
