Glaucon (Ring of Gyges) says that we obey the laws only from fear of punishment. Provide four reasons for obeying the law or ethical principles that do not involve punishment or reward. Is there a difference between people who obey the law out of fear and those who obey the law out of a sense of duty or character? What are those differences? When is it acceptable not to obey the laws? What types of laws ought we obey and which ought we disregard?
