 How much simpler it would be to say that normative language means the same in its moral uses and in its legal uses. While a person who says that you must stop at a red light may display various attitudes, what he or she asserts is a necessity that implies a (presumptively) conclusive reason to stop. If the statement is a statement of law, the necessity is a legal necessity; if the statement is a moral statement, the necessity is a moral necessity.
