Abstract
In his article on « Vampires », in the Dictionnaire philosophique, Voltaire both evokes the phenomenon of the so-called « vampire plague » which hit Central Europe during the 1730s and recalls the controversial interpretations of this phenomenon in France and abroad. He takes advantage of the occasion to renew his anti-religious polemic, with a caustic irony that doesn’t spare even a sincere Voltairian like Jean Baptiste Boyer d’Argens, who had offered a penetrating analysis of this phenomenon in his Lettres Juives. In his text, Voltaire chooses satire rather than an inquiry into causes of the phenomenon, revealing a superficial anthropological approach as well as the limits of an argument conceived as pure ideology
