"To understand how evil controls people, it is necessary to understand the difference between principle and law.
A principle is a truth that creates freedom. A law is a lie that creates slavery.
Principles describe reality. They are knowledge that help you to make use of your world. Because of your intelligence, you recognize principles in everything you do. Every true thing you learn is a principle. The movement of your hands, which foods taste good, mathematics and empathy for friends and all base on principles.
Laws are artificial ideas created by evil men to restrict the thinking and understanding of people. Laws mask themselves in authority so that they can impersonate principles. When people mistake law for principle their freedom is restricted. When people mistake truth for the ideas of authority, their abilities and their wisdom are diminished. This is the purpose of law.
An example of a principle can be found in thermodynamics. A liquid is cooler than a gas. This is a principle. Because this is a principle, it does not restrict us, but enables us. Using this principle, we condense and expand a substance between gas and liquid to create refrigeration. With this principle, we have more understanding and more power. Principles are truths that create freedom.
An example of a law can be found in the culture of royalty. A comer owes homage to the king. This is the law. Because this is a law, it destroys freedom and enslaves. Under this law, a person must neglect usage of their minds, their speech and their actions. They must believe that they are worth less than the king. Notice that unlike a principle, there is no truth in law. It is entirely possible to disrespect the king, and therefore to break the law. Law must be enforced, because there is no truth in it. A law destroys freedom because it is a lie. A principle, however creates freedom because it is knowledge.
That which destroys freedom is evil."
-- Jeremy Locke, "The End of All Evil"
