These rules of propriety, or meum and tuum , and of “good,” “evil,” “lawful,” and “unlawful” in the actions of subjects, are the civil laws; that is to say, the laws of each commonwealth in particular; though the name of civil law be now restrained to the ancient civil laws of the city of Rome, which being the head of a great part of the world, her laws at that time were in these parts the civil law.
