If Simpson understands that for Hart the rule of recognition is itself customary, he is then saying that the concept of one customary rule serving to determine the validity of different customary guidelines is in absent-minded conformity to the concept all laws originate in legislation.
This had the pleased consequence that, in its up to date utility, the universality of the Pure Principle (and Kelsen insisted that solely universal truths might be ‘scientific’) would coincide with that of predominantly global law. While the classical naturalist appears dedicated to the claim that the law necessarily incorporates all moral ideas, this claim doesn’t suggest that the regulation is exhausted by the set of moral ideas.
God’s commands, however, would only have normative validity for those who presuppose the fundamental norm of their respective faith, particularly, that one ought to obey God’s commands. Stanley L.

This permits Kelsen to take care of the identical understanding of the nature of normativity as Pure Regulation’s conception, specifically, normativity qua reasons for motion, with out having to conflate the normativity of morality with that of law. As an empirical matter, many pure law moral theorists are additionally natural regulation authorized theorists, however the two theories, strictly talking, are logically unbiased.
