With regard to the ideas which predominate in the practical part of Kant's system, philosophers only disagree, whilst mankind, I am confident of proving, have never done so. If stripped of their technical shape, they will appear as the verdict of reason pronounced from time immemorial by common consent, and as facts of the moral instinct which nature, in her wisdom, has given to man in order to serve as guide and teacher until his enlightened intelligence gives him maturity. But this very technical shape which renders truth visible to the understanding conceals it from the feelings; for, unhappily, understanding begins by destroying the object of the inner sense before it can appropriate the object. Like the chemist, the philosopher finds synthesis only by analysis, or the spontaneous work of nature only through the torture of art. Thus, in order to detain the fleeting apparition, he must enchain it in the fetters of rule, dissect its fair proportions into abstract notions, and preserve its living spirit in a fleshless skeleton of words. Is it surprising that natural feeling should not recognize itself in such a copy, and if in the report of the analyst the truth appears as paradox? Permit me therefore to crave your indulgence if the following researches should remove their object from the sphere of sense while endeavoring to draw it towards the understanding. That which I before said of moral experience can be applied with greater truth to the manifestation of "the beautiful." It is the mystery which enchants, and its being is extinguished with the extinction of the necessary combination of its elements. LETTER II. But I might perhaps make a better use of the opening you afford me if I were to direct your mind to a loftier theme than that of art. It would appear to be unseasonable to go in search of a code for the aesthetic world, when the moral world offers matter of so much higher interest, and when the spirit of philosophical inquiry is so stringently challenged by the circumstances of our times to occupy itself with the most perfect of all works of art--the establishment and structure of a true political freedom. It is unsatisfactory to live out of your own age and to work for other times. It is equally incumbent on us to be good members of our own age as of our own state or country. If it is conceived to be unseemly and even unlawful for a man to segregate himself from the customs and manners of the circle in which he lives, it would be inconsistent not to see that it is equally his duty to grant a proper share of influence to the voice of his own epoch, to its taste and its requirements, in the operations in which he engages.
