On the other hand, this type of art, like every other, needs an external vehicle of expression. As already stated, the spiritual content has here withdrawn from the external world and its immediate unity into its own world. The sensuous externality of form is consequently accepted and represented, as in the symbolic type, as unessential and transient; furthermore the subjective finite spirit and volition is treated in a similar way; a treatment which even includes the idiosyncrasies or caprice of individuals, character, action, or the particular features of incident and plot. The aspect of external existence is committed to contingency and handed over to the adventurous action of imagination, whose caprice is just as able to reflect the facts given _as_ they are[151], as it can change the shapes of the external world into a medley of its own invention and distort them to mere caricature. For this external element has no longer its notion and significance in its own essential province, as in classical art. It is now discovered in the emotional realm, and this is manifested in the medium of that realm itself rather than in the external and _its_ form of reality, and is able to secure or to recover again the condition of reconciliation with itself in every accident, in all the chance circumstance that falls into independent shape, in all misfortune and sorrow, nay, in crime itself. Hence it comes about that the characteristics of symbolic art, its indifference, incompatibility and severance of Idea from configurative expression, are here reproduced once more, if with essential difference. And this difference consists in the fact that in romantic art the Idea, whose defectiveness, in the case of the symbol, brought with it the defect of external form, has to display itself as Spirit and in the medium of soul-life as essentially self-complete. And it is to complete fundamentally this higher perfection that it withdraws itself from the external element, It can, in short, seek and consummate its true reality and manifestation nowhere but in its own domain. This we may take to be in general terms the character of the symbolic, classical, and romantic types of art, which in fact constitute the three relations of the Idea to its embodiment in the realm of human art. They consist in the aspiration after, the attainment and transcendency of the Ideal, viewed as the true concrete notion of beauty.
