Positively Fabulous: Why It Is Good To Be a Legal Positivist

‘Legal Positivism’ is a much abused term. It is often pejoratively invoked by those occupying both the natural law and critical legal studies ramparts. The former see it as a school of thought which ignores the role in law of those standards and values which have not been deliberately laid down or unintentionally evolved. Positivism, for them, fails because it is prepared to describe a legal world where moral values play no necessary part and where transcendent values may not exist at all. The latter group of critics, not too dissimilarly, see legal positivism’s doctrines as over-reliant on rules and too inclined to accept that a legal system somehow can generate a logically mandated code of answers. In order to defend positivism it is advisable to start with an enunciation of its core precepts. With all that has been written attacking and supporting positivism though, this can be a contentious matter. So instead I shall defend one particular version of positivism, that of H.L.A. Hart. As Hart’s The Concept of Law, first published in 1961, is at worst one of the handful of great legal philosophy texts written in English this century and at best “the classic work of philosophical jurisprudence”, this preference for concentrating on the tangible and identifiable precepts of Hart over the woolly, elusive and frequently caricatured precepts of something disparagingly termed positivism has much to recommend it.
