But, on the other hand, this type of Art,[160] like every other, needs an external vehicle of expression. Now the spiritual has withdrawn into itself out of the external and its immediate oneness therewith. For this reason, the sensuous externality of concrete form is accepted and represented, as in Symbolic art, as something transient and fugitive. And the same measure is dealt to the subjective finite mind and will, even including the peculiarity or caprice of the individual, of character, action, etc., or of incident and plot. The aspect of external existence is committed to contingency, and left at the mercy of freaks of imagination, whose caprice is no more likely to mirror what is given _as_ it is given, than to throw the shapes of the outer world into chance medley, or distort them into grotesqueness. For this external element no longer has its notion and significance, as in classical art, in its own sphere, and in its own medium. It has come to find them in the feelings, the display of which is _in themselves_ instead of being in the external and _its_ form of reality, and which have the power to preserve or to regain their state of reconciliation with themselves, in every accident, in every unessential circumstance that takes independent shape, in all misfortune and grief, and even in crime. Owing to this, the characteristics of symbolic art, in difference, discrepancy, and severance of Idea and plastic shape, are here reproduced, but with an essential difference. In the sphere of the romantic, the Idea, whose defectiveness in the case of the symbol produced the defect of external shape, has to reveal itself in the medium of spirit and feelings as perfected in itself. And it is because of this higher perfection that it withdraws itself from any adequate union with the external element, inasmuch as it can seek and achieve its true reality and revelation nowhere but in itself. This we may take as in the abstract the character of the symbolic, classical, and romantic forms of art, which represent the three relations of the Idea to its embodiment in the sphere of art. They consist in the aspiration after, and the attainment and transcendence of the Ideal as the true Idea of beauty.
