The specificity of any one concept in Jacques Ranciére's oeuvre is difficult to grasp and impossible to localize because, as Ranciére himself admits “I don't speak for members of a particular body or discipline. I write to shatter the boundaries that separate specialists – of philosophy, art, social sciences, etc.” (Ranciére 2007a: 257). This is especially true of Ranciére's conceptual innovation of a partage du sensible (variously translated as “partition” or “distribution” of the sensible); – a term that refers at once to the conditions for sharing that establish the contours of a collectivity (i.e. “partager” as sharing) and to the sources of disruption or dissensus of that same order (i.e. “partager” as separating). In every respect, a partage du sensible is a liminal term that is at once central to Ranciére's analyses of the aesthetics of politics but also requires an exploration of other conceptual specificities in his theoretical lexicon. In this chapter, I explore Ranciére's notion of a partage du sensible by first addressing the multiple meanings of the French verb “partager”; I then outline how Ranciére's partage du sensible is part of his critique of a poetics of knowledge, and especially of Louis Althusser's theoreticism. Finally, I elaborate the political dimensions of this concept by showing that politics involves, for Ranciére, the rearticulation of a partage du sensible by the excluded or unaccounted- for elements in a political society.
