Public health as a justice project. Philosophical approach,vith the objective of building health ethics.

In so far it inscribes the intentions, the possibilities and the means to h eal sick people, of a policy (understood as elaboration, discussion and ado ption of collective choices) and of an ethic (understood in reference to th e principles and the norms that mark such decisions and health practices), the task of public health concerns the idea of justice itself, confronting the 'injustice' of sickness and unhappiness and the inequality between citi zens. According to this decison-making and deontological approach, how shou ld public health be conceived in keeping with the updating of the concept o f justice? Projects, public health and concept of justice primarily require semantic delimitation. However, word accuracy is exceeded as it constitute s, according to the reports concerning the three notions, a working hypothe sis on both fundamental and political ethics registers. We defend three the ories regarding the task of public health which elaborate. taking into acco unt the critical relationships between health, social links and citizenship ; discussions between the involved parties (users, health care providers an d politicians); critical thinking about, including a definition of the mean s brought into play and the beliefs at the core of health conception. Even though the concept of justice is clearly not worked out by the public healt h project, it obviously continuously questions the latter, as it is more ex tensive than any institutional or individual achievement. 'Ethical concern' is therefore building, including dissatisfaction and continuous search for 'taking care' of the social link.
