The Letter VII is without doubt the most important among the letters of Plato. Our goal in this short article is to reflect on the hermeneutics of politics and political left here by Plato. In it, Plato takes a clear position regarding the conception of politics and political leader. Dionysius and Dion will be the central figures of the Charter. Both are presented here as a kind of antithesis of understanding of politics. The philosopher who appears in the Charter with the figure of the political adviser is invited to experience the risk of telling the truth and be on the side of truth. In this search for truth he is also asked to surpass the state and make logos to have materialization in the Ã‰rgon, thus turning the figure of the political advisor into the field of action of the philosophical Ã‰rgon.
