In this paper, the author suggest that the historical and institutional conditions of existence of the concepts which animate legal argumentation – like the historical and institutional conditions of existence of certain forms of law – are of interest not only in their own right, but also because they raise methodological issues for jurisprudence. These include questions about the relationship between concepts and the social phenomena which they purport to categorise; about the relationship between philosophical and other forms of legal (...) theory; and about how a jurisprudence largely dominated by philosophical methods may be brought into productive dialogue with other forms of theoretical analysis. Only by broadening both its horizons and its methods, the author argues, will jurisprudence be capable of illuminating not only doctrinal analysis within particular jurisdictions at particular times, but also comparative and historical scholarship.
