Steffens, in his celebrated lectures, first introduces to Denmark the natural system of nature. About the year 1831, at the period, therefore, when Andersen's nursery stories originated, there is founded in England (the land which took the lead in bringing forward the child in literature) the first society for the prevention of cruelty to animals. Branches are established in France and Germany, where societies spring up in Munich, Dresden, Berlin and Leipsic. Kierkegaard in his "Enten--Eller" (Either--Or) turns the establishment of these societies into ridicule; he sees in it but a phenomenon of the tendency to form associations, which in his eyes is a proof of the lamentable condition of individual personality. If we return now to Denmark, we will observe that the national landscape painting, with its literal imitation of nature, takes its decisive upward soaring flight at precisely the time when nursery stories are devised. Skovgaard paints the lake in which "the ugly duckling" went splashing about, and at the same time--as by a miracle--the large city becomes too small for the citizen of Copenhagen. He finds it wearisome to gaze the whole summer long on its paving-stones, its many houses and roofs, he longs to see a larger bit of the sky, he repairs to the country, lays out gardens, learns to distinguish barley from rye, becomes a rustic for the summer months. One and the same idea, the recovered idea of nature, extends its influence through all the spheres of life, just as the water of an upland stream flowing downward is distributed through a series of different basins. Could an idea produce a more singular effect, or a more suggestive one for contemplation? During the past century there has been nothing similar. We may, as has been wittily remarked, rummage through Voltaire's "Henriade," without finding a single blade of grass; there is no fodder for the horses in it. We may turn over the leaves of Baggesen's poems, without stumbling on a single description of nature, used even as an accessory. What a leap from this poetry to such poetry as that of Christian Winther, in which the human figures are merely used as accessories and the landscape is almost universally the main point of interest, and how far removed was the world, even in his day, from so much as dreaming of a poetry like that of Andersen, in which animals and plants fill the place of man, indeed, almost make man superfluous![4]
