If, then, a sensuous form and configuration is to be correspondent with a true and therefore concrete content, such must in the third place likewise be as clearly individual, entirely concrete and a self-enclosed unity. This character of concreteness, predicable of both aspects of art, the content no less than the representation, is just the point in which both coalesce and fall in with one another. The natural form of the human body is, for example, such a sensuous concrete capable of displaying Spirit in its essential concreteness and of adapting itself wholly to such a presentment. For which reason we must quit ourselves of the idea that it is a matter of mere accident that an actual phenomenon of the objective world is accepted as the mode in which to embody such a form coalescent with truth. Art does not lay hold of this form either because it is simply there or because there is no other. The concrete content itself implies the presence of external and actual, we may even add the sensuous appearance. But to make this possible this sensuous concrete, which is essentially impressed with a content that is open to mind, is also essentially addressed to the inward conscious life, and the external mode of its configuration, whereby it is visible to perception and the world of idea, has for its aim the being there exclusively for the soul and mind of man. This is the sole reason that content and artistic conformation are dovetailed one into the other. The _purely_ sensuous concrete, that is external Nature as such, does not exclusively originate in such an end. The variously coloured plumage of birds is resplendent unseen; the notes of this song are unheard. The Cereus[136], which only blossoms for a night, withers away without any admiration from another in the wilderness of the southern forests; and these forests, receptacles themselves of the most beautiful and luxuriant vegetation, with the richest and most aromatic perfumes, perish and collapse in like manner unenjoyed. The work of art has no such naïve and independent being. It is essentially a question, an address to the responding soul of man, an appeal to affections and intelligence.
