Over the weekend the members of the research project on the Agrarian Republics had an opportunity to discuss ongoing research in a semi-formal setting together with other researchers from the University of Lausanne: prof. Christian Grosse (Institut d’histoire et anthropologie des religions), and doctoral students Damiano Bardelli (history) Matthieu Clément (history), Aris Della Fontana (history, Scuola Normale Superiore di Pisa-UNIL), Stefano Torres (IHAR) and Remy Zanardi (IHAR). Both days were full of stimulating discussions not only about individual research projects of each doctoral student, but also about transversal themes in the study of the eighteenth and seventeenth century: cultural transfers between linguistic fault-lines; different facets of education; creation of scholarly networks. Honouring the place of our meeting, we did not omit to discuss the links between Jean-Jacques Rousseau and the two important subjects of the research project: the Spirit of Legislation and the educational journeys of the Mniszechs.
