Quick Answer
The ring of Gyges is a thought experiment from Book II of [Plato](/thinkers/plato)'s Republic, introduced by Glaucon to test the nature of justice. The story: a shepherd named Gyges finds a ring that makes its wearer invisible; with the power of invisibility, he seduces the queen, murders the king, and takes the throne. The question Glaucon poses: if the just person and the unjust person both possessed such a ring, would anyone remain just? Glaucon's challenge is that justice is valued only for its consequences — the reputation, the rewards — and that no one is just for the sake of justice itself. The thought experiment sets up the central question of the Republic: is justice good in itself, or only for its rewards? Plato's answer, through Socrates, is that justice is good in itself — the just soul is the healthy soul, and the life of justice is the life worth living, with or without the ring.
