Un impensé de la sémiotique : la variation (diachronique, sociale, expérientielle)

The paper starts from the premise that the epistemological requirements of the semiotic discipline have led it to overlook the variation (geographical, chronological, social) of the subjects it deals with. After reviewing the historical and methodological reasons for this setting aside, this paper outlines a general theory of semiotic variation. For this, it distinguishes two families of variationthe variation of practices and the variation of attitudesand three axes of variation: the spatial axis, the time axis and the social axis. It also highlights the two types of forces that govern the variation: centripetal forces and centrifugal forces. The paper concludes with the epistemological impact that the concern about variation may have on semiotics and disciplines that, such as sociology and anthropology, have made variation their subject.
