On the Ancient Titles of Plato’s Republic
IN HIS Lives of Eminent Philosophers, Diogenes Laertius cites Thrasylus (d. 36 CE) to the effect that the work of Plato we call The Republic had two Greek titles, Politeia (Πολιτεία) and peri dikaiou (περὶ δικαίου; DL 3.60). From the better-known former one, we get (somewhat indirectly) our title The Republic. We will return to that, but first let’s consider the second title. This is usually translated as On Justice, but that is incorrect. The Greek word for justice is dikaiosune. While derived from the same root (dike), the word dikaiou, a pronoun, means a just man or person. Further, the word ‘just’ here is somewhat misleading. In modern English we tend to equate justice with social justice. In that sense a just man would be one who deals fairly with others. But the Greek concept of dike is broader — more like what we call ‘in right measure’ (the goddess Dike is sometimes pictured holding a balance scale). A more accurate translation of dikaiou therefore is a rightly ordered or righteous person.
The word politeia means a system of government, a form of political regime, or, by extension, a constitution. We get the word Republic not from the Greek word, but from the title of Cicero’s dialogue, Res publica (the public thing), which he styled in imitation of Plato’s work. However, as noted by Tarrant (2012) and others, some manuscripts give this title as politeiai, a plural form. This would be translated as systems of government, constitutions, or regimes.
We end up with the possibility that (although Plato, as far as we know, himself named none of his dialogues) the title of the work we call The Republic would, by ancient readers, have been understood as something like Regimes: On the Righteous Person. This would have made it clear that the dialogue is a work on ethics and psychology, with discussion of city governments supplying an allegorical framework for investigating the good and bad government of ones soul or psyche.
