 Voltaire, an admirer of Newton, also wrote "Candide" at least in part to discredit Leibniz's claim to having discovered calculus and Leibniz's charge that Newton's theory of universal gravitation was incorrect.Leibniz's long march to his present glory began with the 1765 publication of the "Nouveaux Essais", which Kant read closely.In 1768, Louis Dutens edited the first multi-volume edition of Leibniz's writings, followed in the 19th century by a number of editions, including those edited by Erdmann, Foucher de Careil, Gerhardt, Gerland, Klopp, and Mollat.
