Most of his works are either pious or written for the instruction of his royal pupil. The duke de Beauvilliers had copies of most of those letters and papers, addressed to the duke of Burgundy, which Louis XIV. destroyed. Among these, his directions with regard to the conscience of a king, is full of enlightened morality. He had a great love for all classic learning. His Telemachus is full of traits which show that he felt all the charm of Greek poetry. He was made member of the French academy the 31st of March, 1693, in the place of Pelisson. His oration on the occasion was simple and short. He afterwards addressed his Dialogues on Eloquence to the academy. These prove the general enlightenment of his mind, and the justice of his views. His remarks on language are admirable. When he speaks of tragedy, he rises far above Corneille, Racine, and Voltaire, in his conception of the drama; in that, as in every other species of composition, he tried to bring back his countrymen to simplicity and nature. He desired them to speak more from the heart, less from the head. He shows how what the French falsely deemed to be delicacy of taste, took all vivid colouring and truth from their pictures, giving us a high enamel, in place of vigorous conception and finished execution. He gives just applause to Molière; his only censure is applied to the Misanthrope: "I cannot pardon him," he says, "for making vice graceful, and representing virtue as austere and odious." All his works are essentially didactic; and they have the charm which we must expect would be found in the address of one so virtuous and wise, and calm, to erring passion-tost humanity.
