If a true and therefore concrete content is to have corresponding to it a sensuous form and modelling, this sensuous form must, in the third place, be no less emphatically something individual, wholly concrete in itself, and one. The character of concreteness as belonging to both elements of art, to the content as to the representation, is precisely the point in which both may coincide and correspond to one another; as, for instance, the natural shape of the human body is such a sensuous concrete as is capable of representing spirit, which is concrete in itself, and of displaying itself in conformity therewith. Therefore we ought to abandon the idea that it is a mere matter of accident that an actual phenomenon of the external world is chosen to furnish a shape thus conformable to truth. Art does not appropriate this form either because it simply finds it existing or because there is no other. The concrete content itself involves the element of external and actual, we may say indeed of sensible manifestation. But in compensation this sensuous concrete, in which a content essentially belonging to mind expresses itself, is in its own nature addressed to the inward being; its external element of shape, whereby the content is made perceptible and imaginable, has the aim of existing purely for the heart and mind. This is the only reason for which content and artistic shape are fashioned in conformity with each other. The _mere_ sensuous concrete, external nature as such, has not this purpose for its exclusive ground of origin. The birds' variegated plumage shines unseen, and their song dies away unheard, the _Cereus_[134] which blossoms only for a night withers without having been admired in the wilds of southern forests, and these forests, jungles of the most beautiful and luxuriant vegetation, with the most odorous and aromatic perfumes, perish and decay no less unenjoyed. The work of art has not such a naïve self-centred being, but is essentially a question, an address to the responsive heart, an appeal to affections and to minds.
