The Cultural and Academic Programme of the Quaderni Fiorentini per la Storia del Pensiero Giuridico Moderno as Conveyed by its Introductory Pages in the First Thirty Years - The Quaderni Fiorentini per la storia del pensiero giuridico moderno (Florentine Notebooks on the History of Modern Legal Thinking) were instrumental in innovating international legal studies. The "Introductory Pages" written in the course of the publication’s first thirty years have recently been compiled in a single volume by their founder and editor (P. Grossi, Trent’anni di pagine introduttive. Quaderni Fiorentini 1972-2001, Giuffré, Milan 2009, pp. XXVIII-252). As you read them, you can retrace the stages in a cultural and academic programme that found the history of modern legal thinking to be a fertile meeting ground for historians, sociologists and philosophers of law and scholars of positive law, all interested in the unity of legal science and of its aperture to the other human sciences. In Paolo Grossi’s thinking, the reference to the "historical nature of legal knowledge" was put to use as the tool for verifying "a host of certainties", observing "the eclipse of a host of dogmas", doubting "a host of claimed conquests", the opportunity to establish a relationship between "the lawyer (and his methods)" and "society (and its future)". This is an approach that focuses on the topics of legal method and of the system of law sources at work in the transformation of the dynamics of legal orders, an approach so incisive as to be of real help in understanding the present.
