    criticised

    In the article ‘Rorarius’ of his Dictionnaire (1697; 2nd ed. 1702) Bayle questioned Leibniz’s pre-established harmony: how could a dog’s soul pass from pleasure to pain unprompted? P.

    criticised by

    Leibniz’s Theodicy (1710) answered Bayle’s claim that reason cannot reconcile evil with a good God, arguing that faith and reason agree and this is the best possible world. G. W. Leibniz, Essais de Théodicée (1710), Discours préliminaire, Parts I–III; SEP “Leibniz on the Problem of Evil”

Works

Position

Bayle used erudition as a weapon of doubt. In his Historical and Critical Dictionary the footnotes swell into long arguments showing that reason, pressed far enough, entangles itself in contradictions – above all when it tries to reconcile a good God with the evil in the world. Faith cannot be proved, only held. After the revocation of the Edict of Nantes, which cost his brother his life, he argued for tolerance: even an erring conscience has rights, and a society of atheists could be morally decent. Leibniz wrote his Theodicy in reply, and the Enlightenment from Voltaire to Hume drew on his arsenal.

Life & context

Pierre Bayle was born in 1647 in Le Carla in southern France, the son of a Calvinist pastor. Briefly a Catholic convert as a student in Toulouse, he returned to his faith and had to flee. After teaching at the Protestant academy of Sedan he settled in Rotterdam in 1681, where he taught at the Illustrious School, edited the learned journal Nouvelles de la République des Lettres (1684–87) and lost his professorship in 1693 after clashes with fellow Huguenots. He died there in 1706.
