Usages et fonctions du concept de cité de Dieu dans la première philosophie de Gottfried Wilhelm Leibniz

Uses and functions of the concept of City of God in the early Leibniz's Philosophy. The use of the syntagms city of God in Leibniz's philosophy is well known, but the meaning of a such concept and the role it's dedicated to is unclear. What could be the difference between the augustinian's use and the leibnizian's use? What would be its significance when it is not metaphoric? It seems, for a better knowing of a such concept, that a study of the occurrences in the early Leibniz's philosophy is decisive. It will appear that Leibniz's uses reveal a real philosophical purpose: conjuring Hobbesian's contractualism, and fighting Atheism, inscribing the concept of city of God in Nature itself.
