Simpson writes, Hart like Kelsen does not commit more than a small part of The Idea of the Legislation to the detailed application of his idea to the widespread regulation” (84). The word “legislation” is used less and less in science, as many laws are only true beneath restricted circumstances.
Criticism of law is certainly an ethical matter however a foul regulation should still be a valid regulation and create a authorized (however not ethical) obligation. A idea is an evidence of some aspect of the natural world that’s properly-substantiated by information, tested hypotheses, and legal guidelines.
By deliberately avoiding any explanation of what it’s that may ground an agent’s alternative of endorsing the authorized perspective, or any given basic norm, Kelsen left probably the most urgent questions concerning the normativity of regulation unanswered. As Kelsen himself repeatedly argued, a successful revolution brings about a radical change within the content of the fundamental norm.
Kelsen notes that, in this respect, the Pure Principle of Regulation has an affinity with American ‘ legal realism ‘. At the same time, though it is not easy to reconcile together with his rejection of practical reason, Kelsen was emphatic that politicians should assist and make use of legal science.
In keeping with pure law ethical principle, the ethical requirements that govern human habits are, in some sense, objectively derived from the character of human beings and the character of the world. Thus, the classical naturalist does not deny that human beings have appreciable discretion in creating natural law.
