The Ring of Gyges
Platonic Ethics
The claim
"If a person could act invisibly, with no possibility of being caught or punished, they would still have reason to act justly."
The premises that support it
- Justice is good in itself, not merely for its consequences.
- The just person's soul is well-ordered; the unjust soul is at war with itself.
- Therefore, even invisible, the just person flourishes more than the invisible tyrant.
The counter-example
Glaucon's challenge: imagine two people — a just person mistakenly believed unjust, suffering every penalty; and an unjust person believed just, receiving every reward. The unjust person clearly fares better. So why should anyone choose justice if they could escape detection?
