The abb\u00E9 was a free-thinker, for a man ostensibly of the cloth: Helv\u00E9tius quoted his remark that, if all the good and all the evil done in the name of religion were weighed together, the evil would preponderate. His great work was his Description de France, one of the secondary sources used by Edward Gibbon for his Decline and Fall of the Roman Empire. Louis was born in Charleville-M\u00E9zi\u00E8res, the son of Pierre Dufour, seigneur de Longuevue et Goisel, a Gentilhomme de Normandie and governor of Charleville. His elder brother, who had been expected to succeed to the title and was already a field marshal awarded the Order of St. Louis, was killed at the battle of Ramillies, 1706. After his death in Paris a volume of Longueruana was published, based on the recollections of a devoted amanuensis who had transcribed Longuerue's savant conversations. In 1769 a further selection of fugitive pieces from among his papers was published."@en . "Louis Du Four de Longuerue"@en . . . . "3383"^^ . . . . . . . . . . . . . . . . . . "1084232015"^^ . . . . .
