Les Cahiers du GRIF - Année 1992 - Volume 46 - Numéro 1 - Pages 97-102My aim is to consider the relationship between the Politics and the Poetics or, to be more precise, to point out the two-sided characterization of the human being by Aristotle. On one hand, the human being is defined in the Politics as a political animal, endowed with logos, that is with reason and speech. But he is, on the other hand, described in the Poetics as the only animal having a natural ability to imitate. Though it is rather unusual to connect these two points of view, my hypothesis is, however, that the « mimetic » ability involves a basic uncertainty in which is rooted the political ability. Hence, if Aristotle refuses to eliminate risk in the political life, he does so on the grounds of a confrontation between rules or institutions and this basic instability. 6 pages Source : Persée ; Ministère de la jeunesse, de l’éducation nationale et de la recherche, Direction de l’enseignement supérieur, Sous-direction des bibliothèques et de la documentation.
