Every one acknowledges that greatness, purity, and goodness of Soul have also their sensuous expressions. But how is this conceivable, unless the principle that acts in Matter be itself cognate and similar to Soul?
For the representation of the Soul there are again gradations in Art, according as it is joined with the merely Characteristic, or in visible union with the Charming and Graceful.
Who perceives not already, in the tragedies of Æschylus, the presence of that lofty morality which is predominant in the works of Sophocles? But in the former it is enveloped in a bitter rind, and passes less into the whole work, since the bond of sensuous Grace is still wanting. But out of this severity, and the still rude charms of earlier Art, could proceed the grace of Sophocles, and with it the complete fusion of the two elements, which leaves us doubtful whether it is more moral or sensuous Grace that enchants us in the works of this poet.
The same is true of the plastic productions of the early and severe style, in comparison with the gentleness of the later.
If Grace, besides being the transfiguration of the spirit of Nature, is also the medium of connection between moral Goodness and sensuous Appearance, it is evident how Art must tend from all points toward it as its centre. This Beauty, which results from the perfect interpenetration of moral Goodness and sensuous Grace, seizes and enchants us when we meet it, with the force of a miracle. For, whilst the spirit of Nature shows itself everywhere else independent of the Soul, and, indeed, in a measure opposed to it, here, it seems, as if by voluntary accord, and the inward fire of divine love, to melt into union with it; the remembrance of the fundamental unity of the essence of Nature and the essence of the Soul comes over the beholder with sudden clearness—the conviction that all antagonism is only apparent, that Love is the bond of all things, and pure Goodness the foundation and substance of the whole Creation.
Here Art, as it were, transcends itself, and again becomes means only. On this summit sensuous Grace becomes in turn only the husk and body of a higher life; what was before a whole is treated as a part, and the highest relation of Art and Nature is reached in this—that it makes Nature the medium of manifesting the soul which it contains.
But though in this blossoming of Art, as in the blossoming of the vegetable kingdom, all the previous stages are repeated, yet, on the other hand, we may see in what various directions Art can proceed from this centre. Especially does the difference in nature of the two forms of Plastic Art here show itself most strongly. For Sculpture, representing its ideas by corporeal things, seems to reach its highest point in the complete equilibrium of Soul and Matter—if it give a preponderance to the latter it sinks below its own idea—but it seems altogether impossible for it to elevate the Soul at the expense of Matter, since it must thereby transcend itself. The perfect sculptor indeed, as Winckelmann remarks apropos of the Belvedere Apollo, will use no more material than is needful to accomplish his spiritual purpose; but also, on the other hand, he will put into the Soul no more energy than is at the same time expressed in the material; for precisely upon this, fully to embody the spiritual, depends his art. Sculpture, therefore, can reach its true summit only in the representation of those natures in whose constitution it is implied that they actually embody all that is contained in their Idea or Soul; thus only in divine natures. So that Sculpture, even if no Mythology had preceded it, would of itself have come upon gods, and have invented such if it found none.
Moreover as the Spirit, on this lower platform, has again the same relation to Matter that we have ascribed to the Soul (being the principle of activity and motion, as Matter is that of rest and inaction), the law that regulates Expression and Passion must be a fundamental principle of its nature.
But this law must be applicable not only to the lower passions, but also equally to those higher and godlike passions, if it is permitted so to call them, by which the Soul is affected in rapture, in devotion, in adoration. Hence, since from these passions the gods alone are exempt, Sculpture is inclined from this side also to the imaging of divine natures.
The nature of Painting, however, seems to differ entirely from that of Sculpture. For the former represents objects, not like the latter, by corporeal things, but by light and color, through a medium therefore itself incorporeal and in a measure spiritual. Painting, moreover, gives out its productions nowise as the things themselves, but expressly as pictures. From its very nature therefore it does not lay as much stress on the material as Sculpture, and seems indeed for this reason, while exalting the material above the spirit, to degrade itself more than Sculpture in a like case; on the other hand to be so much more justified in giving a clear preponderance to the Soul.
