This dissertation aims to present and discuss the concept of regimes of identification of the arts, developed by the French philosopher Jacques Rancière from the middle of the nineteen nineties. We are particularly interested in perceiving how, through this concept, the historical contingency of the notion of art acquires a polemical dimension, becoming the starting point of the construction of an argumentative scene that aims, most of all, at making perceptible the appearence of a dissensual power in the field of artistic practices since the end of the 18th century. First, in order to develop our discussion, we underline certain aspects of Ranciere s philosophical method, with the purpose of highlighting his efforts in reconfiguring the debates in which he interferes, without however, providing univocal answers to the questions with which he comes across. Secondly, we present the concept of regimes of identification and the main characteristics of the three regimes analyzed by Rancière: the ethical regime of images, the poetic regime of arts and the aesthetic regime of art. Last of all, we ask ourselves about which ways the concept of regimes can help us think in a contemporary relevance for the field of art and its dissensual power.
