Abstract
Rapports between religion and health are analysed here, within the context of contemporary France, based upon a distinc tion between the major "official" instances of belief regulation (State, science, dominant religious confessions) and the "nebula" of heterodoxies, meaning by this representations and social practi ces which set themselves up in competition with the "offcial"sec tor, for example astrology or unorthodox medicines or post-psycho-analytical, psycho-corporal groups of activities. In this perspective, the reference to the linguistic notion of the "floa ting significant", introduced by LEVI-STRA USS, enters into an enlightening symbiosis with the psycho-analytical notion of "transitional phenomenon", defined by WINNICOTT.
