A principle is an abstract object which shows a point that allows the concrete formation of a norm, rule or a law. Principles are the generalizations which arise from induction and the difference between a principle and a rule is that rules are based upon principles. A rule can be a principle but a principle may not be rule. Rule can be defined as a formal and widely-accepted statement or fact. For example, if an organization allows 20 minutes break to the employees then it is a principle for all the employees to come back within 20 minutes, however if the organization is very flexible and does not make it a rule then some employees may not follow this principle.
