He is the translator in French, with Pierre Gothot, of L'Ordinamento Giuridico of Santi Romano (2nd edition: Paris, Dalloz, 2002).

The work applies an analytical approach to addressing issues that the philosophy and sociology of law deal with most often as a global vision of complex realities.

Lucien François attempts to characterize the difference between a law and an ultimatum from for example, a bandit demanding "your money or your life !"

Lucien François suggests that such an analysis requires a "microscopic" method, proceeding from the simple to the complex.

He crafts a new vocabulary for discussing law, seeking abstraction and precision, in attempt to avoid the imprecision of conventional terms.

He asserts that conventional legal language was developed for pragmatic purposes rather than in the service of science, for convenience rather than formal clarity.

François is convinced that legal theoreticians miss many points – as in many law books – if they begin their study of the huge and complex building blocks that States constitute with a prematurely synthetic approach.

These elements appear in their simplest form in chapter 9, Brief Encounters between Two People, which deals with the basic occurrences of the jureme, where the essential characteristics of what the author calls « the notification system » become apparent.

Chapter 13 requires the longest developments discussing the cooperation between non-delegated powers, under a great variety of forms, from people waiting in line to organizations functioning on a hierarchical basis.

Chapter 14 adds one more element that is required to create an embryonic juridical State system, namely, the « jureme of supremacy » emitted by the « dominant aggregate ».

At a university symposium on this book, the author was introduced as someone who " lifts the veil, debunks fictions, dismantles artifices in order to get to the bottom of real relationships of power" (E. Delruelle).

Now the legal sciences are equipped with a conceptual apparatus which enables the analysis of any human society" (R. Jacob); "a formidable power of persuasion "(P. Mayer); "Lucien François goes beyond appearances" (P. Brunet)
