Medical decision making relies heavily on the notion of the quality of a person's life in providing a reason to utilize one therapy over another or to withhold certain therapies altogether. The concept of quality of life, however, lacks clear definition as well as consensus on its constitutive elements. ;Chapter one engages a basic controversy in the literature: whether 'quality of life' should be understood as a subjective concept, or whether objective "lists" can help us assess a person's quality of life. Chapter two examines whether anthropological data might provide guidance. While it is often argued that anthropological data supports relativism, John Finnis argues that anthropological data supports universalism which, in turn, bolsters objectivist claims. I argue that anthropological data may plausibly be interpreted to support either subjective or objective accounts, and thus, does not settle our approach to quality of life. ;Chapter Three examines objective list theories, in particular those of Bernard Gert and John Finnis. I find Gert's account to be problematic because it seems incomplete. Finnis's criteria, too, seems ultimately indefensible. Thus, I conclude that while objectivist claims may offer insight into human values and motivations, existing accounts are flawed. Chapter Four examines subjective accounts of quality of life. I focus on "preference satisfaction" accounts. While these accounts provide intuitively plausible descriptions, they fall victim to a host of difficulties. Perhaps the best example of this is the "fleeting preferences" problem, which undermines our confidence in making life-and-death decisions on the basis of quality of life considerations. ;The concluding chapter offers that much progress can be made by understanding quality of life in terms of finding meaning in life. Thus, the quality of one's life is determined by how much purpose and meaning is found in that life. While this notion is not without its problems, it does capture the complex elements of the kinds of cases in which we are particularly interested, and combines some of the best features of both the objective and subjective accounts.
