Voltaire could not build: he could only pull down: he was the very Vitruvius of ruin. He has bequeathed to us not a single doctrine to be called by his name, not a single addition to the stock of our positive knowledge. But no human teacher ever left behind him so vast and terrible a wreck of truths and falsehoods, of things noble and things base, of things useful and things pernicious. From the time when his sojourn beneath the Alps commenced, the dramatist, the wit, the historian, was merged in a more important character. He was now the patriarch, the founder of a sect, the chief of a conspiracy, the prince of a wide intellectual commonwealth. He often enjoyed a pleasure dear to the better part of his nature, the pleasure of vindicating innocence which had no other helper, of repairing cruel wrongs, of punishing tyranny in high places. He had also the satisfaction, not less acceptable to his ravenous vanity, of hearing terrified Capuchins call him the Antichrist. But whether employed in works of benevolence, or in works of mischief, he never forgot Potsdam and Frankfort; and he listened anxiously to every murmur which indicated that a tempest was gathering in Europe, and that his vengeance was at hand.
He soon had his wish. Maria Theresa had never for a moment forgotten the great wrong which she had received at the hand of Frederic. Young and delicate, just left an orphan, just about to be a mother, she had been compelled to fly from the ancient capital of her race; she had seen her fair inheritance dismembered by robbers, and of those robbers he had been the foremost. Without a pretext, without a provocation, in defiance of the most sacred engagements, he had attacked the helpless ally whom he was bound to defend. The Empress Queen had the faults as well as the virtues which are connected with quick sensibility and a high spirit. There was no peril which she was not ready to brave, no calamity which she was not ready to bring on her subjects, or on the whole human race, if only she might once taste the sweetness of a complete revenge. Revenge, too, presented itself, to her narrow and superstitious mind, in the guise of duty. Silesia had been wrested not only from the House of Austria, but from the Church of Rome. The conqueror had indeed permitted his new subjects to worship God after their own fashion; but this was not enough. To bigotry it seemed an intolerable hardship that the Catholic Church, having long enjoyed ascendency, should be compelled to content itself with equality. Nor was this the only circumstance which led Maria Theresa to regard her enemy as the enemy of God. The profaneness of Frederic's writings and conversation, and the frightful rumours which were circulated respecting the immorality of his private life, naturally shocked a woman who believed with the firmest faith all that her confessor told her, and who, though surrounded by temptations, though young and beautiful, though ardent in all her passions, though possessed of absolute power, had preserved her fame unsullied even by the breath of slander.
To recover Silesia, to humble the dynasty of Hohenzollern to the dust, was the great object of her life. She toiled during many years for this end, with zeal as indefatigable as that which the poet ascribed to the stately goddess who tired out her immortal horses in the work of raising the nations against Troy, and who offered to give up to destruction her darling Sparta and Mycenae, if only she might once see the smoke going up from the palace of Priam. With even such a spirit did the proud Austrian Juno strive to array against her foe a coalition such as Europe had never seen. Nothing would content her but that the whole civilised world, from the White Sea to the Adriatic, from the Bay of Biscay to the pastures of the wild horses of the Tanais, should be combined in arms against one petty State.
She early succeeded by various arts in obtaining the adhesion of Russia. An ample share of spoil was promised to the King of Poland; and that prince, governed by his favourite, Count Bruhl, readily promised the assistance of the Saxon forces. The great difficulty was with France. That the Houses of Bourbon and of Hapsburg should ever cordially co-operate in any great scheme of European policy, had long been thought, to use the strong expression of Frederic, just as impossible as that fire and water should amalgamate. The whole history of the Continent, during two centuries and a half, had been the history of the mutual jealousies and enmities of France and Austria. Since the administration of Richelieu, above all, it had been considered as the plain policy of the Most Christian King to thwart on all occasions the Court of Vienna, and to protect every member of the Germanic body who stood up against the dictation of the Caesars.
