This paper argues that the medical conception of health as absence of disease is a value-free theoretical notion. Its main elements are biological function and statistical normality, in contrast to various other ideas prominent in the literature on health. Apart from universal environmental injuries, diseases are internal states that depress a functional ability below species-typical levels. Health as freedom from disease is then statistical normality of function, i.e., the ability to perform all typical physiological functions with at least typical efficiency. (...) This conception of health is as value-free as statements of biological function. The view that health is essentially value-laden, held by most writers on the topic, seems to have one of two sources: an assumption that health judgments must be practical judgments about the treatment of patients, or a commitment to "positive" health beyond the absence of disease. I suggest that the assumption is mistaken, the commitment possibly misdescribed. (shrink)

Accounts of the concepts of function and dysfunction have not adequately explained what factors determine the line between low‐normal function and dysfunction. I call the challenge of doing so the line‐drawing problem. Previous approaches emphasize facts involving the action of natural selection (Wakefield 1992a, 1999a, 1999b) or the statistical distribution of levels of functioning in the current population (Boorse 1977, 1997). I point out limitations of these two approaches and present a solution to the line‐drawing problem that builds on the (...) second one. (shrink)

A basic question of medical ethics is whether the norms governing medical practice should be understood as the application of principles and rules of the common morality to medicine or whether some of these norms are internal or proper to medicine. In this article we describe and defend an evolutionary perspective on the internal morality of medicine that is defined in terms of the goals of clinical medicine and a set of duties that constrain medical practice in pursuit of these (...) goals. This perspective is developed by means of a critical examination of the essentialist conception of the internal morality of medicine advocated by Edmund Pellegrino and the critique of internal morality approaches by Robert Veatch and Tom Beauchamp.

This essay develops an account of health, the functional efficiency theory, which derives from Christopher Boorse's biostatistical theory. Like the BST, the functional efficiency theory is a nonevaluative view of health, but unlike the BST, it argues that the fundamental theoretical task is to distinguish levels of efficiency with which the parts and processes within organisms and within systems within organisms function. Which of these to label as healthy or pathological is of secondary importance. Because the statistical distributions that Boorse's (...) account relies on are distributions of functional efficiency, the functional efficiency theory arguably complements rather than challenges the BST.

After surveying and criticizing some earlier definitions of "disease", we propose that a general term--malady--be used to represent what all diseases, illnesses, injuries, etc., have in common. We define a malady as the suffering, or increased risk of suffering an evil in the absence of a distinct sustaining cause. We discuss the key terms in the definition: evil, distinct sustaining cause, and increased risk. We show that the role of abnormality is to clarify these terms rather than to be used (...) directly in the definition of malady. (shrink)
