Well throughout the history of natural law, natural law has always meant intellectual law. It is logic and epistemology, metaphysics, etc… It wasn’t until Spinoza and Hobbes came along and changed the definition of natural to mean where the beasts roam and that the state is legitimate cause it is bringing civilization out of the beastly inclinations of nature. They completely perverted what natural meant in natural law for their own manipulative ends. History is a war of definitions over the labels, at times, and sometimes it can be tracked down on who started spreading the lies, in this case, Hobbes and Spinoza.
