Justice is an ideal that characterizes Greek thought throughout its historical development since
Homer. It reaches its clearest formulation with Plato, who regarded it as the “virtue of the
soul”, conceived as summary of its three functions, and with Aristotle, who turned it into the
political virtue par excellence, emphasizing its intersubjective character. Plutarch, who interprets
the Platonic and Aristotelian doctrine of justice in light of modern Stoicism and posterior
Aristotelianism, transforms justice into an ethical and political ideal at the same time: a virtue
that springs from the soul, where it has its roots, to seek outside. In this respect, it represents for
him one of the most perfect virtues and one of the highest forms of humanity, because it allows
the politician - provided with an appropriate education and moral formation - to carry out his
activity for the benefit of the members of his community, showing courage in doing and saying
what is right and fair.
