[Crises of public health, medicine, society?].

Public health is in crisis. Apart from temporary factors, this crisis could have also its origin in theoretical and conceptual insufficiencies relative to the definition of this scientific domain. Organisational and institutional conditions needed for the strengthening of public health are discussed in relation with the localization of its production sites, taking into account the needed synthesis or consensus to reach and in view of the larger and valuable intellectual traditions to which it belongs. The crisis of public health is only part of a crisis of medicine and of our modern societies.
