Taking the cue from the recent Italian edition of 'La prudence chez Aristote' (1963) written by P. Aubenque, in this article, 'La phronesis umana. A margine di La prudenza in Aristotele di Pierre Aubenque', we want to retrace the genesis of the concept of phronesis in Aristotle: on the one hand, this allows us to investigate the relationship between theory and praxis, which is far from clear and which has considerable implications; on the other hand, with this analysis we have the opportunity to problematize the political horizon and this enables us to speak of the virtue, which otherwise would not be explained.
