Listen to yourself

Legalising rights to the people can be a method to allow one or a few to exclude someone or something in the interest of someone else or something else. This expresses the main difference of opinion between a civilisation and a state of rule by law. A civilisation being the stage of human social development and organisation which is considered most advanced or the process by which a society or place reaches an advanced stage of social development and organisation to allow all human beings the right to live in compliance to the declaration of equal human rights. 
The only way in such a system, to disallow someone these rights, would have to be by establishing a definition to pronounce that that someone is not a human being.
