In order to grasp the link between the “natural” and the “historical” that characterizes the reality of art, this paper aims to an examination of the concept of “artistic field” in contrast with “art world”. The notion of field reflects the dynamical status of the reality of art as institutional process, that roots in the sociological and anthropological experience of human being in his interaction with his environment. The analysis of this interaction carried out by Pierre Bourdieu and Arnold Gehlen shows how an institution such as art arises as stabilization of nature and “habitualization” of experience structures which are operating already at the level of perception and which culminate in the praxis of figuration. This means that an artistic field implies an historical and material (rather than formal) apriori, that the notion of “art world” tends to hide and to repress.
