What we call the Common Law arises from the normal interaction of people with one another according to their nature and customs, Common law is based on common sense which helps maintain peace and equity in the community. This Common Law is the human manifestation of the universal Natural Law, and creates no hierarchy or dominating force over people. On the contrary, common law engenders and defends the natural liberty and just equality of all people without regard to rank or distinction.
The root of the common law lies in the Anglo-Saxon tribal traditions of Europe and their village-based system of justice and government. In this tradition, authority arose from the will of the people and not a ruler, since liberty was understood to dwell inherently within every man and woman born. Rights are not granted by one person to another, since they exist “ab initio”: from the beginning. All people therefore have the inborn capacity to govern themselves, to know right from wrong and act justly, and to judge for themselves all things, including the conduct of others.
This inborn capacity, rather than imposed statutes, was the tribal guarantee of social peace and harmony. But alongside this common law arose a contrary system of governance derived from state-level Empires and their religions that saw people not as inherently free but rather as chattels and the property of others. This imperial system of domination has always been at permanent war with the liberty and equality of the common law.
