While he was in Paris, two seats had fallen vacant in the Academy. But what chance could there be of one for the hero of a public scandal, a notorious firebrand, like Voltaire? Villars and Richelieu did their best for him—in vain.

He professed himself gaily indifferent, and was bitterly disappointed. He had to further postpone too the production of his “Prodigal Son.” He could not give that son, he said, so unpopular a father.

The man needed rest after his battles. He had soon what was far better than rest to one of his vivid temperament—a victory. In August began his correspondence with Prince Frederick of Prussia, afterwards Frederick the Great. It comprises many letters remarkable on both sides, extraordinary on Voltaire’s. It lasted for many years—before they met, in the early golden days of an almost lover-like infatuation—and long after they had quarrelled and parted. Voltaire was not the man at any time to be insensible to the honour of being the correspondent of one who was “almost a king.” He was a great deal too impressionable not to be in some sort the child of his age. In all his glowing dreams of liberty, he never wished royalty abolished—only restrained, enlightened, ennobled. And behold! the means were given him now, himself to show a king the way in which kings should walk—to influence a man who would influence a great people—to teach Europe, by a master to whom it must listen, those emancipating truths which were the passion of Voltaire’s own soul. What an opportunity! It was characteristic of the man that he realised and seized it at once.

“Believe that there have never been any good kings save those who, like you, have begun by teaching themselves, by knowing men, by loving the truth, by hating persecution and superstition. There is no prince who, thus thinking, cannot bring back the golden age to his country. Why do so few sovereigns seek this great good? You know why it is, monseigneur; it is because they all think more of royalty than of humanity.”

These words occur in Voltaire’s very first letter, written August 26, 1736. They are the text of all the others. If there were compliments and flatteries, French grace and politesse, and the adulation of the “Solomon of the North” somewhat overdone, those were the inevitable courtly trappings which adorned all letters of the time. The monitor of Solomon, as shown in that very first letter, knew himself to be the monitor; and, for all that exquisite turn of phrase and those pretty eulogies, was going to remain the monitor to the end. The flattery was by no means all humbug either. This royal pupil was the aptest that ever man had. He answered his Voltaire, not unworthily. At five-and-twenty he was himself philosopher and thinker: as great a natural genius as he was a natural barbarian. All learning and cultivation left him as much the one as the other.

The correspondence, once started, went on its way with a will. On Voltaire’s side it was from the first profoundly philosophic. His style was as clear, easy, and lucid when he wrote on the deepest and subtlest problems of free-will and personal identity as when he wrote scandal to Theriot or bagatelles to Mademoiselle Quinault. He wrote on the most abstruse subjects with a limpid simplicity of language, unachieved by any other writer before or since. It is the greatest glory of Voltaire as an author in general, as well as the author of the letters to Frederick the Great, that he made profound truths, common truths, and the knowledge that had been the heritage of a few, the heritage of all.

Madame du Châtelet read the letters, of course, before they were despatched from Cirey. One fills eleven large pages of print and is practically an Essay on Personal Liberty—reasonable enough, said Madame, to bring its author to the stake. Theriot showed Frederick’s letters about the salons of Paris: the prudent Voltaire thinking that the correspondence with a king might just as well do him all the good it could, and proclaim to his enemies that all temporal powers did not hate and fear him. At Cirey, the royal association certainly gave pleasure at first. Madame was singularly superior to kingly attractions: but Frederick was a thinker as well as a prince and loved philosophy as she did. She had not begun to look upon him as a rival in her lover’s affections. In his very first letter Voltaire had declined an invitation to be his visitor on the score that friends should always be preferred before kings.

The bloom of that summer of 1736 came and went on Cirey. Jore was hardly silenced and by no means forgotten when Voltaire flung aside his princely philosopher, as it were, to reply to a long, scandalous, and very personal attack which bitter old J. B. Rousseau, infuriated by the “Temple of Taste,” had made upon his rival, in a publication called the “Bibliothèque Française.” That attack dated from the May of this year. It was not until September 20th Voltaire decided to answer it. He had been very patient, or had crouched awhile for a surer spring. His answer is a masterpiece of gay and biting satire. “Rousseau has printed in your journal a long letter on me in which, happily for me, there are only calumnies, and, unfortunately for him, there is no wit. What makes the thing so bad, gentlemen, is that it is entirely his own ... it is the second time in his life he has had any imagination. He has no success when he is original.... As for his verses, I can only wish for the sake of all the honest people he attacks, that he should go on writing in the same style.”

And in answer to Rousseau’s insinuations on Voltaire’s origin, “I have a valet who is his near relative and a very honest man. The poor youth begs me every day to pardon his relation’s bad verses.”

And in reply to that little story Rousseau had once circulated about Voltaire’s profane behaviour at a mass, “Do you think ... it sits well on the author of the ‘Moïsade’ to accuse me of having talked in church sixteen years ago?... Thank God, that Rousseau is as clumsy as he is hypocritical. Without this counterpoise he would be too dangerous.” The letter finishes by recalling all the humiliating episodes in Rousseau’s life he would have most wished forgotten.
