The study of animal behavior and the development of human society highlights that people learned to follow and enforce rules of conduct long before they could verbally express them. These rules evolved to create order within groups, which is essential for their survival. While simpler animals often rely on innate rules, higher vertebrates learn and transmit rules culturally, creating distinct traditions. This learning process enables rapid changes and adaptations within groups.
Research shows that many animal societies have developed complex behaviors that help reduce conflict and maintain peace. For instance, established territories help decrease fighting and regulate population growth. Social hierarchies often ensure that only the strongest individuals reproduce. These behaviors illustrate a system of rules that govern actions, which emerged naturally in both animals and humans.
As humans evolved and developed language, they began to articulate and teach these existing rules. Rules can be thought of as tendencies to act in certain ways, which come into play alongside various impulses. These propensities can be abstract and govern a wide range of actions, often before language existed. Thus, the origin and purpose of rules is different from how they are expressed verbally. Even today, many societal rules remain unarticulated, indicating a complex system of conduct influencing human behavior.
