ANR Research Diary : A Forgotten Tradition : French Socialist Intellectuals and Reformers, 1830-1870.The UTOPIES19 Research Diary publicizes the various research activities of the different research groups involved in the Agence National de la Recherche (ANR) program, “A Forgotten Tradition: French Socialist Intellectuels and Reformers, 1830-1870”. Interdisciplinary in its approach, the UTOPIES19 program examines intersections between history, philosophy, sociology and economics through the particular study of mid-19th French socialism. Through several different thematic studies of French socialism, the Utopies19 Research Diary seeks to renew and revise existing interpretations of the theory and practice of early non-Marxist socialism in France. In particular, its research efforts focus on the key philosophical, political, social and economic concepts of the major representatives of French socialism during the 1830-1879 period: most notably the Saint-Simonians; the Fourierists; Étienne Cabet and his communist disciples; Louis Blanc; François Vidal; Constantin Pecqueur; Philippe Buchez and his follower Auguste Ott; Pierre and Jules Leroux; Jean Reynaud; and, finally, Pierre-Joseph Proudhon and his socialist and anarchist disciples and descendants. The UTOPIES19 Research Diary is designed to consolidate research information for its team members and to present their results-in-progress, as well as to signal when project materials appear in seminars, conferences and publications, printed or online.
