This paper proposes that the formation of opinion and of the discursive and inclusive, essential to the public sphere, will come at some point to the aesthetic rationality, considered as a central theme of Arentd's thought. After defining the action, the author proceeds to characterize political activity as well as plurality. This allows us to understand the revelatory nature of the action and its relationship to the aesthetic judgement, as its concern is the particular and the subject who judges.
