[6] References to the power over his mind of the French Revolutionary principles abound in Goethe's writings. The violence of the first impression, which began with the affair of the necklace, had reached a climax in '90 and '91, and this, along with the ineffaceable memories of the _Werther_ and _Goetz_ period, which his heart remembered when in his intellectual development he had left it far behind, accounts in a large measure for his yielding temporarily at least to the spell of Napoleon's genius, and for the studied but unaffected indifference to German politics and to the War of Liberation. Even of 1809, the year of Eckmühl, Essling, and Wagram, and the darkest hour of German freedom, Goethe can write: "This year, considering the beautiful returns it brought me, shall ever remain dear and precious to memory," and when the final uprising against the French was imminent, he sought quietude in oriental poetry--Firdusi, Hafiz, and Nisami. [7] Of his _Contes_ Taine said: "Depuis les Grecs aucun artiste n'a taillé un camée littéraire avec autant de relief, avec une aussi rigoureuse perfection de forme." [8] It is remarkable that Carlyle and Schopenhauer should have lived through four decades together yet neither know in any complete way of the other's work. Carlyle nowhere mentions the name of Schopenhauer. Indeed _Die Welt als Wille und Vorstellung_, though read by a few, was practically an unknown book both in Germany and England until a date when Carlyle was growing old, solitary, and from the present ever more detached, and new books and new writers had become, as they were to Goethe in his age, distasteful or a weariness. Schopenhauer, on the other hand, already in the "thirties," had been attracted by Carlyle's essays on German literature in the _Edinburgh_, and though ignorant as yet of the writer's name he was all his life too diligent a reader of English newspapers and magazines to be unaware of Carlyle's later fame. But he has left no criticism, nor any distinct references to Carlyle's teaching, although in his later and miscellaneous writings the opportunity often presents itself. Wagner, it is known, was a student both of Schopenhauer and Carlyle. Schopenhauer's proud injunction, indeed, that he who would understand his writings should prepare himself by a preliminary study of Plato or Kant, or of the divine wisdom of the Upanishads, indicates also paths that lead to the higher teaching of Wagner, and--though in a less degree--of Carlyle.
