From Schiller's letters on aesthetics

"If the nobility of art has survived the nobility of nature, it also goes before it like an inspiring genius, forming and awakening minds. Before truth causes her triumphant light to penetrate into the depths of the heart, poetry intercepts her rays, and the summits of humanity shine in a bright light, while a dark and humid night still hangs over the valleys.

"But how will the artist avoid the corruption of his time which encloses him on all hands? Let him raise his eyes to his own dignity, and to law; let him not lower them to necessity and fortune. Equally exempt from a vain activity which would imprint its trace on the fugitive moment, and from the dreams of an impatient enthusiasm which applies the measure of the absolute to the paltry productions of time, let the artist abandon the real to the understanding, for that is its proper field. But let the artist endeavor to give birth to the ideal by the union of the possible and of the necessary. Let him stamp illusion and truth with the effigy of this ideal; let him apply it to the play of his imagination and his most serious actions, in short, to all sensuous and spiritual forms; then let him quietly launch his work into infinite time.

"But the minds set on fire by this ideal have not all received an equal share of calm from the creative genius—that great and patient temper which is required to impress the ideal on the dumb marble, or to spread it over a page of cold, sober letters, and then intrust it to the faithful hands of time. This divine instinct, and creative force, much too ardent to follow this peaceful walk, often throws itself immediately on the present, on active life, and strives to transform the shapeless matter of the moral world."
