The chapter discusses the evolution of theories of justice in health and healthcare. It traces Norman Daniels’s Rawlsian account, as well as the criticism it received. It then goes on to discuss two rival theories that sprang in opposition to Daniels’s, namely a sufficientarian family of theories and luck egalitarian justice in health. Special attention is devoted to three focal questions: the pattern of justice in health, its currency, and its scope, that is, the what, how, and who. Under the latter, the chapter discusses the requirements of global justice in health, and investigates what temporal unit is appropriate in thinking of just healthcare.
