Abstract
Just Health, by the well-known American philosopher Norman Daniels, has the ambitious goal of presenting 'an integrated theory of justice and population health, to address a set of theoretical and real-world challenges to that theory, and to demonstrate that the theory can guide our practice with regard to health both here and abroad.' Daniels's fundamental question is what we owe each other in the way of the protection and promotion of health. He thinks this is fruitfully dealt with by breaking it down and answering three separate questions: (i) what is the moral importance of health? (ii) when are differences in health unjust? and (iii) how should we meet health needs fairly when we cannot meet them all?
