Sulla genesi di dike : filosofia della giustizia nella Repubblica di Platone

The objective of this article is to attempt to reconstruct the philosophical and political genesis of the notion of “dike” within Plato’s thought, with particular reference to the thought of the pre-Socratic philosophers.
Through recalling the etymological roots of the terms “themis”, “dike” and “ius”, the different faces of “justice” will be shown, culminating in Platonic thought, developed in the Republic, in which justice becomes an idea, that is, a meta-virtue on which the political balance of the polis must be based.
