 The preceding section discussed ways that happiness might figure prominently even in non-mental state theories of well-being. The question there concerned the role of happiness in theories of well-being. This is a different question from how important happiness is for well-being itself. Even a theory of well-being that includes no mention at all of happiness can allow that happiness is nonetheless a major component or contributor to well-being, because of its relation to the things that ultimately constitute well-being. If you hold a desire theory of well-being, for instance, you will very likely allow that, for most people, happiness is a central aspect of well-being, since most people very much desire to be happy. Indeed, some desire theorists have argued that the account actually yields a form of hedonism, on the grounds that people ultimately desire nothing else but happiness or pleasure (Sidgwick 1907 [1966], Brandt 1979, 1989).
