Abstract

While recognizing that H.L.A. Hart’s The Concept of Law has exerted a powerful and continuing influence on general jurisprudence, Brian Simpson finds it wanting. Simpson argues that Hart’s determination to make broad generalizations about the nature of a legal system deflected him from the important task of attending to the particularities of actually-existing law. Moreover, he identifies Hart as a ‘hedgehog’ in Isaiah Berlin’s sense: a thinker whose work gives expression to a ‘single central vision’ (in Hart’s case, law as a system of rules). This critique of Hart leads Simpson to argue for an approach to legal philosophy that is more attentive to the details of existing legal systems. But Simpson fails to present his readers with the theoretical approach for which he argues. This essay seeks to make good this deficiency in his response to The Concept of Law. To this end, it uses the writings of two philosophers on whom Simpson draws (Berlin and Michael Oakeshott) with the aim of enriching Hart’s contribution to general jurisprudence. Moreover, it finds in this Hart-Oakeshott-Berlin-based interdisciplinary theory (HOBBIT) a basis on which to throw much light on Britain as a distinctive form of politico-legal life.
