This chapter examines the notion of "holistic" health. The literature today is full of references to "holistic care" and "holistic medicine" but one rarely sees any content to this term, except for some general phrases about man being a biological, psychological and social being. The chapter begins with an overview of different conceptions of health and illness throughout history, demonstrating that the notion of health has deep-rooted cultural associations to ideas about balance and harmony, virtue and morality, societal norms and behaviors. A brief presentation of modern theories of health follows. Afterwards, an analysis of scientific literature shows how the term "holistic" is in need of a philosophical grounding in order to make any genuine contributions to health care. Finally, a sound holistic view of health is extrapolated from the theory of psychosomatics presented in  Chap. 5, which should be an appreciated contribution to the literature on health.
