But both Goethe and Schiller paved the way for Romanticism not only positively, by their proclamation of the rights of passion, but also negatively, by the conscious attitude of opposition to their own age which they assumed in their later years. In another form, the Romanticist's aversion to reality is already to be found in them. I adduce two famous instances of the astonishing lack of interest shown by Goethe, the greatest creative mind of the day, in political realities; they prove at the same time how keen was his interest in science. Writing of the campaign against France during the French Revolution, a campaign in which he took part, he mentions that he spent most of his time in observing "various phenomena of colour and of personal courage." And after the battle of Jena Knebel writes: "Goethe has been busy with optics the whole time. We study osteology under his guidance, the times being well adapted to such study, as all the fields are covered with preparations." The bodies of his fallen countrymen did not inspire the poet with odes; he dissected them and studied their bones. Such instances as these give us some impression of the attitude of aloofness which Goethe as a poet maintained towards the events of his day. But we must not overlook the fine side of his refusal to write patriotic war-songs during the struggle with Napoleon. "Would it be like me to sit in my room and write war-songs? In the night bivouacs, when we could hear the horses of the enemy's outposts neighing, then I might possibly have done it. But it was not my life, that, and not my affair; it was Theodor Körner's. Therefore his war-songs become him well. I have not a warlike nature nor warlike tastes, and war-songs would have been a mask very unbecoming to me. I have never been artificial in my poetry." Goethe, like his disciple Heiberg, was in this case led to refrain by the strong feeling that he only cared to write of what he had himself experienced; but he also tells us that he regarded themes of a historical nature as "the most dangerous and most thankless."
