The Ring of Gyges (story from Plato's Republic)

Within Book II of Plato's 'Republic', the story of the Ring of Gyges presents a moral thought-experiment where a shepherd finds a ring granting invisibility, enabling him to act unjustly without consequence.

Plato uses the tale to examine whether people are just by nature or due to social constraints and to argue for the necessity of virtue in exercising power responsibly.

Jay Dyer references it to illuminate the One Ring's symbolic function as absolute power that corrupts those lacking virtue.

The Gyges story is central to philosophical discussions of morality, justice, and the nature of ethical behavior under anonymity or unchecked power.

It remains widely cited in ethics and political philosophy.
