Every rule is based on a principle.
Principles result from values.
When a value is important to us, we develop its application by defining principles. These help us implement our values. At times, a principle is not sufficient; that is when rules come in. They describe the boundaries of the application of our values.
This is true for everyone.
However, everyone has their logic; thus, rules, principles, and values differ from one to the other.
As individuals, we may make rules among ourselves. In a community, this role is taken by laws and policies.
This doesn’t imply that everyone will follow these rules. However, knowing their existence provides every member of the community with the community’s expectations. Acknowledging them is a way of confirming one’s belonging to the community.
