a. They are the foundation of the state motto.
The State of Georgia has never officially adopted a state motto, but the state seal, adopted in 1799, features a banner with three words on it, which have served as the de facto state motto: "Wisdom, Justice, Moderation."
Book 4 of Plato's Republic lists four key virtues of a good government: wisdom, courage, moderation, and justice. In the state seal of Georgia, there is also depicted a soldier with a drawn sword -- which could be taken as a depiction of courage. If so, all four of Plato's primary virtues of government can be seen as included in the Georgia seal. But most certainly, "Wisdom, Justice, Moderation" -- taken as the Georgia state motto -- come from the philosophical principles of Plato.
