The Ring of Gyges /ˈdʒaɪˌdʒiːz/ (Ancient Greek: Γύγου Δακτύλιος, Gúgou Daktúlios, Attic Greek pronunciation: [ˈɡyːˌɡoː dakˈtylios]) is a hypothetical magic ring mentioned by the philosopher Plato in Book 2 of his Republic (2:359a–2:360d).^[1] It grants its owner the power to become invisible at will. Using the ring as an example, this section of the Republic considers whether a rational, intelligent person who has no need to fear negative consequences for committing an injustice would nevertheless act justly.
