"As Strauss points out, Nietzsche does not believe in "a science of morals which teaches the only true morality," and this specifically includes rational or utilitarian morality: rather for Nietzsche what is natural is only the binding or burdening of man to precisely unnatural and unreasonable laws. "Over and against the ruinous permissiveness of anarchism, Nietzsche asserts that precisely long-lasting obedience to unnatural and unreasonable nomoi is the ‘moral imperative of nature.' Physis calls for nomoi while preserving the distinction, nay, opposition of physis and nomos."
