Is health care a need?

This paper aims to provide an argument for saying that a publicly funded health care system, available to all free at the point of delivery, is morally superior to a market system, and to provide a framework for deciding questions about which forms of health care should be included in such a public system. The argument presents health care as a 'head', in the sense of something to which human beings are morally entitled as a necessary condition for a life worthy of human dignity. Alternative arguments for similar conclusions, proposed by Daniels and Buchanan, are critically examined and rejected.
