As the most suitable illustration of Taine's historical methods Lady Blennerhassett selects his study of Napoleon. That, she thinks, is "the severest test of the author's skill." Taine did not, like Fournier and others, attempt to write a history of Napoleonic facts. The strategical and tactical genius which enabled Napoleon to sweep across Europe and to crush Austria and Prussia on the fields of Austerlitz and Jena had no attraction for him. He wrote a history of ideas. True to his own psychological habit of thought, he endeavoured to "reconstruct the figure of Napoleon on psychological and physiological lines." The justification of this method is to be found in the fact, the truth of which cannot be gainsaid, that a right estimate of the character of Napoleon affords one of the principal keys to the true comprehension of European history for a period of some twenty stirring years. History, Lord Acton said, "is often made by energetic men steadfastly following ideas, mostly wrong, that determine events." Napoleon is a case in point. "The man in Napoleon explains his work." But what were the ideas of this remarkable man, and were those ideas "mostly wrong"? His main idea was certainly to satisfy his personal ambition. "Ma maîtresse," he said, "c'est le pouvoir," and in 1811, when, although he knew it not, his star was about to wane, he said to the Bavarian General Wrede, "In three years I shall be master of the universe." He was not deterred by any love of country, for it should never be forgotten that, as Lady Blennerhassett says, "this French Caesar was not a Frenchman." Whatever patriotic feelings moved in his breast were not French but Corsican. He never even thoroughly mastered the French language, and his mother spoke not only bad French, but bad Italian. Her natural language, Masson tells us, was the Corsican _patois_. In order to gratify his ambition, all considerations based on morality were cast to the winds. "I am not like any other man," he told Madame de Rémusat; "the laws of morality and decorum do not apply to me." Acting on this principle he did not hesitate to plunge the world into a series of wars. _Saevit toto Mars impius orbe._
