The concept of well-being is central to issues in moral philosophy. Despite its importance (or because of it), there has been little consensus on the nature of well-being. This paper argues that efforts to define well-being have confused what it means for a person to be “well-off” with what it means for a person’s life “to go well”. In contrast to the mainstream view, this article argues that the concepts of quality of life and well-being are different and provocatively suggests that the standard of evaluation for each may differ as well.
