Written by a philosopher closely involved in the design and creation of courses for health care professionals, this book poses two fundamental questions - "What is health?" and "How can more health be achieved?". These questions form part of a continuing debate which is often characterised by confusion and ambiguity. This book, by viewing the debate from a novel perspective, clears away misunderstanding, clarifies the basic issues, explores different theories of health, and throws a gauntlet at the feet of those responsible for the organisation and delivery of health care. A provocative and often controversial discussion of the philosophy of health care, the book clarifies the foundations for health promotion and education, and puts forward a more precise and comprehensive theory of health than has ever been offered before. It should be read by all health professionals, from medical students and nurses to health visitors, medical sociologists and philosophers.
