This paper, divided into two thematically integrated parts, offers a reconstruction of the conceptions of law that matured in 17th century English jurisprudence. Part 1 begins with a brief sketch of the development of the common law from the 12th to the 17th centuries. Mature common law theory took as central the idea of law as ‘reasonable usage’ which combined, not without tension, the ideas of law as common custom of the realm and law as common reason. Part 1 explores competing understandings of these ideas, and the distinction introduced by Sir Edward Coke between ‘natural reason’ and the special ‘artificial reason’ of the law. In Part 2, the author analyses this notion of law's ‘artificial reason’, and discusses the role of natural law and positivist ideas in common lawyers' view of the normative foundations of law. Sir Matthew Hale's sophisticated attempt to reconcile the tensions evident in his inherited conception of law is a special focus of this section.
