The Separability Thesis: A Comparison Between Natural Law and Legal Positivism

The purpose of this paper is to examine the separability of law and morality within an analytic jurisprudential framework. The paper is comprised of four parts. First, the separability thesis will be discussed and defined. Second, Hart’s legal positivist account of law will be presented, which defends the separability thesis. Third, two objections from a natural law perspective (classical and contemporary) will be proposed against the legal positivist position, thereby rejecting the separability thesis. Each objection will be accompanied by a possible Hartian reply. Finally, I will offer a novel analysis of the arguments as well as state why I find the Hartian approach preferable to the natural law theorist’s in regard to the separability thesis
