In Book 2 of Plato 's The Republic , Glaucon and Adeimantus present the myth of the Ring of Gyges , by means of which Gyges made himself invisible. They then ask Socrates , "If one came into possession of such a ring, why should he act justly?" Socrates replies that although no one can see one's body, the soul is disfigured by the evils one commits. The disfigured and corrupted soul (antithesis of the beautiful soul) is imbalanced and disordered, and, in itself, is undesirable, regardless of any advantage derived from acting unjustly. The picture of Dorian Gray is the means by which other people, such as his friend Basil Hallward, may see Dorian's distorted soul.
