Though natural law is a universal law, you cannot derive from it a universally suitable body of civil law. Bodies of law will vary in content based on peculiarities of geography, commerce, the people’s character, religious diversity, and numerous other types of circumstances. Some laws will be present in all or most civil societies, such as prohibitions of murder. These are universal because they are so close to human nature that they will not alter with changes in circumstances. But many laws are indeed based in circumstances and thus particular and mutable.
