 It is worth noting (as Johnston 2011 observes) that even if Plato’s is the first philosophical discussion of justice, a concern with what an individual is due as a matter of justice is a driving issue in Homer’s Iliad, though there is no counterpart concern there with justice as a property of a society or tribe. So even Plato’s philosophical concerns are building on well-established questions about what justice requires of us in our treatment of one another.
