Condillac et Mably : Dix lettres inédites ou retrouvées

Condillac and Mably : ten unpublished or rediscovered letters, presented by François Moure au. This article concerns seven letters by Condillac which had been lost since the end of the 19th Century at least, two other unpublished ones, and an unpublished letter by Mably. They provide a more exact reading of known documents and lead to reflections on the fate of the La Condamine-Maupertuis archives, which are the equivalent of the Berlin Formey archives for relations between Prussia and France during the Enlightenment. Investigations, as yet unfinished, in the Jagelon Library in Cracow, the Berlin State Library, the Archives of the Paris Science Academy, or in recent Paris auctions, provide provisional conclusions concerning these broken up collections.
