The problem of the self has recently regained a wide interest in the philosophical panorama. The
need to rethink the agent has then encouraged the rediscovery of Ancient Philosophy. Focusing
on Aristotelian practical philosophy, this paper aims to demonstrate the intrinsic circularity
existing between the agent and his context. To give evidence of this theory, it will be necessary
to investigate the extensive concept of ethos, the meanings of which embrace both individual
and collective dimension. Moreover, this itinerary through the Aristotelian thought will be the
occasion for putting the rebirth of interest towards Ancient Philosophy into question.
