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)

This book offers a unique synthesis of past and current work on the structure, meaning, and use of negation and negative expressions, a topic that has engaged thinkers from Aristotle and the Buddha to Freud and Chomsky. Horn's masterful study melds a review of scholarship in philosophy, psychology, and linguistics with original research, providing a full picture of negation in natural language and thought; this new edition adds a comprehensive preface and bibliography, surveying research since the book's original publication.

Cet ouvrage est la thèse de doctorat en médecine présentée en 1943 par Georges Canguilhem, augmentée, lors de sa réédition vingt ans plus tard, de réflexions philosophiques sur la signification du terme « normal » en médecine. La thèse débute par une étude historique sur l’identité des phénomènes normaux et pathologiques, dogme de la pensée médicale au XIXe siècle. La seconde partie est une étude systématique, sous la forme d’une analyse critique, des concepts de normal et de pathologique. Georges Canguilhem (...) (1904-1995), philosophe puis médecin, contribua à rénover l’épistémologie française. (shrink)
