In Plato’s dialogue The Republic, Glaucon argues that people do not voluntarily do what is right. According to Glaucon, anyone who has the means to do something unjust and get away with it will do so. Glaucon illustrates his point by telling the story of Gyges. Gyges, a shepherd, finds a magic ring. He accidentally discovers that wearing this ring renders him invisible. He uses the power of the ring to seduce the queen, kill the king, and take over the kingdom. Divide the class into two groups (pro and con) to debate the following proposition: Whenever people have the opportunity to act unjustly without any fear of getting caught or anyone thinking the worse of them, they do so.
