Different stories construct different realities, and to the extent young people can be helped to see this, they can begin making more intelligent decisions about how to live their own lives. I would suggest that the crudest of human societies are those held together by force. This is quite natural. It is close to the animal world. In societies constructed on principles of force, people are governed by fear.
Alliances form based on mutual self-interest.
Oaths of allegiance are common. The virtues of cunning, strength, and loyalty are taught, and revenge is the motivating principle. Stories that teach fear as the primary human reality teach people to act out of personal passion, getting what they want because they can get it, without much regard for those they don't need or fear. Promises characteristically take the form of threats. The paradigmatic relationship is that between master and slave.
