This is the paper:
“Variétés. Essai de dialectique rationnelle”. Annales de Mathématiques pures et appliquées, tome 7 (1816-1817), p. 189-228
(“Varieties. Essay about rational dialectic”, By J.D. Gergonne). Between else, in this paper we find the first use of the symbols “C” and “Ɔ”, which later evolved into the modern symbols “$\subset$” and “$\supset$”, used in set theory and, in older texts, for implication.
You can find it here, in French.
If there isn't any, I believe it deserves one. I would certainly do it, if I could.
