  The edition of Leibniz’s philosophical works in Latin and French, published by Rudolph Erich Raspe (Leibniz 1765; cf. Hallo 1934) contained some up to then unpublished letters and six pieces from the unpublished papers, of which two, “Difficultates quaedam logicae” and “Historia et commendatio linguae charactericae”, are relevant to logic. The most important feature of Raspe’s edition was the first publication of the “Nouveaux Essais sur l’entendement humain” which had been missing for sixty years. They influenced, e.g., Bernard Bolzano who regarded Leibniz as an ally when writing his seminal Wissenschaftslehre (Bolzano 1837, 2014; Mugnai 2011).
