The correct relationship between us is certainly rooted in nature; we are just unaware of it and unfamiliar with it. We each therefore do whatever we think is right. Take a look at the assortment of constitutions and laws that have been created in every which nation.
In that aspect, the relationships that used to exist among ancient tribes and barbarians were the healthiest relationships, because they resulted from a natural closeness to one another. They were all a single family, a clan; and that is the most natural thing. The farther humanity has gone from these kinds of relationships, establishing other kinds of relationships based on our own intelligence and evil desires, the more we have corrupted the relationships between people, and that is the cause, the reason why we are ruining our lives.
