At nineteen he entered the
Society of Jesus and preached at
Amiens,
Versailles, and
Turin. When Voltaire began to issue his
Essai sur les moeurs (1754), which the Catholic Church considered an attack on Christianity, Nonnotte published, anonymously, the
Examen critique ou Réfutation du livre des moeurs; and when Voltaire finished his publication (1758), Nonnotte revised his book, which he published as
Erreurs de Voltaire (2 vols., 1762). He dealt with what he saw as historical and doctrinal errors contained in Voltaire's work. Nonnotte's work reached the sixth edition in 1774. Voltaire retorted in his
Eclaircissements historiques, and the back and forth attacks continued for twenty years. Nonnotte's publication continued to circulate, and was translated into Italian, German, Polish, and Portuguese. After the
suppression of the Jesuits by king
Louis XV, Nonnotte withdrew to Besançon. In 1779 he added a third volume to the
Erreurs de Voltaire, namely, ''L'esprit de Voltaire dans ses écrits
, for which he could not obtain the approval of the Paris censor. Against the Dictionnaire philosophique, in which Voltaire had recapitulated all his attacks on Christianity, Nonnotte published the Dictionnaire philosophique de la religion'' (Avignon, 1772), in which he replied to all the objections then brought against religion. The work was translated into Italian and German. Towards the end of his life Nonnotte published
Les philosophes des trois premiers siècles (Paris, 1789), in which he contrasted the ancient and the modern philosophers. The work was translated into German. He also wrote
Lettre à un ami sur les honnêtetés littéraires (Paris, 1766), and
Réponse aux Éclaircissements historiques et aux additions de Voltaire (Paris, 1774). These publications obtained for their author a eulogistic Brief from
Pope Clement XIII (1768), and the congratulations of St.
Alphonsus Liguori. The latter declared that he had always at hand his "golden works" in which the chief truths of the Faith were defended with learning and propriety against the objections of Voltaire and his friends. Nonnotte was also the author of ''L'emploi de l'argent
(Avignon, 1787), translated from Maffei; Le gouvernement des paroisses
(posthumous, Paris, 1802). All were published under the title Oeuvres de Nonnotte'' (Besançon, 1819). ==Works==
