From Schiller's letters on aesthetics

"The misfortune of his brothers, of the whole species, appeals loudly to the heart of the man of feeling; their abasement appeals still louder: enthusiasm is inflamed, and in souls endowed with energy the burning desire aspires impatiently to action and facts. But has this innovator examined himself to see if these disorders of the moral world wound his reason, or if they do not rather wound his self-love? If he does not determine this point at once, he will find it from the impulsiveness with which he pursues a prompt and definite end. A pure, moral motive has for its end the absolute; time does not exist for it, and the future becomes the present to it directly; by a necessary development, it has to issue from the present. To a reason having no limits the direction towards an end becomes confounded with the accomplishment of this end, and to enter on a course is to have finished it."

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."

From Schiller's letters on aesthetics

"Now the term natural condition can be applied to every political body which owes its establishment originally to forces and not to laws, and such a state contradicts the moral nature of man, because lawfulness can alone have authority over this. At the same time this natural condition is quite sufficient for the physical man, who only gives himself laws in order to get rid of brute force. Moreover, the physical man is a reality, and the moral man problematical. Therefore when the reason suppresses the natural condition, as she must if she wishes to substitute her own, she weighs the real physical man against the problematical moral man, she weighs the existence of society against a possible, though morally necessary, ideal of society. She takes from man something which he really possesses, and without which he possesses nothing, and refers him as a substitute to something that he ought to possess and might possess; and if reason had relied too exclusively on him she might, in order to secure him a state of humanity in which he is wanting and can want without injury to his life, have robbed him even of the means of animal existence, which is the first necessary condition of his being a man. Before he had opportunity to hold firm to the law with his will, reason would have withdrawn from his feet the ladder of nature."
