Though we all have need of doctors, the amount of faith we place in their advice seems to vary from age to age. At the moment, we live in an era of increasing scepticism. The cost, the effectiveness and the humanity of modem medicine are all the subject of controversy. Has bio-medicine really contributed much towards better health? Or is it mostly due to better nutrition, sanitation and housing? Do surgery or chemotherapy on a massive scale actually cure us or are they both ineffective and iatrogenic, piloducing rather than mitigating human misery? Does medicine free us from disease or does it serve as an instrument of social control? The new philosophy calls all in doubt.The new philosophers are a mixed bunch -historians, lawyers, theologians, acupuncturists, ecologists, community physicians, faith healers, activists, statisticians and social scientists. One of the things we have in common, apart from an interest in health, is the hope that we might wax as conventional medicine wanes. How likely is this? This is the question that this paper sets out to explore, though it focusses on just one segment of the new philosophers, the non-medical academics and their aspirations to re-shape the course of medical practice. It asks what chance have sociologists or statisticians actually got to re-shape the medical world?In attempting to answer this question, the paper is divided into five main sections. The first offers a quick historical sketch of the development of a scientific approach within medicine, while the second describes the rapid growth of various non-clinical disciplines with an interest in health and disease and their assault on the medical citadel. It focusses primarily on the extent to which they are accepted as colleagues by the medical profession and provides several reasons for thinking that the power of the non-clinical disciplines is growing, that some doctors welcome the prospect while others are somewhat alarmed. This interesting vision is then heavily qualified. The third section observes that, for all the extraordinary fragmentation of medicine into different specialisms, the profession has maintained a separate community, a solitary and isolated way of life which normally overrides the internal division of labour. To penetrate this is a hard task indeed. Moreover, as
