(α) The first art which comes next to sculpture is that of painting. It avails itself for a medium of its content and the plastic configuration of the same of visibility as such, to the extent that it is differentiated in its own nature, in other words is defined in the continuity of colour. No doubt the material of architecture and sculpture is likewise both visible and coloured. It is, however, not, as in painting, visibility in its pure nature, not the essentially simple light, which by its differentiating of itself in its opposition to darkness, and in association with that darkness gives rise to colour[164]. This quality of visibility made essentially ideal[165] and treated as such no longer either requires, as in architecture, the abstractly mechanical qualities of mass as appropriate to materials of weight, nor, as is the case with sculpture, the complete dimensuration of spatial condition, even when concentrated into organic forms. The visibility and the making apparent, which belong to painting, possess differences of quality under a more ideal mode—that is, in the specific varieties of colour—which liberates art from the objective totality of spatial condition, by being limited to a plane surface.
On the other hand the content also attains the widest compass of particularity. Whatever can find a place in the human heart, as emotion, idea, and purpose, whatever it is capable of actually shaping—all such diversity may form part of the varied presentations of painting. The entire world of particular existence, from the most exalted embodiment of mind to the most insignificant natural fact, finds a place here. For it is possible even for finite Nature, in its particular scenes and phenomena, to form part of such artistic display, provided only that we have some reference to conscious life which makes it akin to human thought and emotion[166].
(β) The second art which continues the further realization of the romantic type and forms a distinct contrast to painting is that of music. Its medium, albeit still sensuous, yet proceeds into still profounder subjectivity and particularization. We have here, too, the deliberate treatment of the sensuous medium as ideal, and it consists in the negation and idealization into the isolated unity of a single point[167], the indifferent external collocation of space[168], whose complete appearance is retained by painting and deliberately feigned in its completeness. This isolated point, viewed as this process of negation, is an essentially concrete and active process of cancellation within the determinate substance of the material medium, viewed, that is, as motion and vibration of the material object within itself and in its relation to itself. Such an inchoate ideality of matter, which no longer appears under the form of space, but as temporal ideality[169], is sound or tone. We have here the sensuous set down as negated, and its abstract visibility converted into audibility. In other words sound liberates the ideal content from its fetters in the material substance. This earliest[170] secured inwardness of matter and impregnation of it with soul-life supplies the medium for the intimacy and soul of Spirit—itself as yet indefinite—permitting, as it does, the echo and reverberation of man's emotional world through its entire range of feelings and passions. In this way music forms the centre of the romantic arts, just as sculpture represents the midway point of arrest between architecture and the arts of the romantic subjectivity. Thus, too, it forms the point of transition between the abstract, spatial sensuousness of painting and the abstract spirituality of poetry. Music carries within itself, like architecture, and in contrast to the emotional world simply and its inward self-seclusion, a relation of quantity conformable to the principles of the understanding and their modes of co-ordinated configuration[171].
(γ) We must look for our third and most spiritual type of artistic presentation among the romantic arts in that of poetry. The supreme characteristic of poetry consists in the power with which it brings into vassalage of the mind and its conceptions the sensuous element from which music and painting began to liberate art. For sound, the only remaining external material retained by poetry, is in it no longer the feeling of the sonorous itself, but is a mere sign without independent significance. And it is, moreover, a sign of idea which has become essentially concrete, and not merely[172] of indefinite feeling and its subtle modes and gradations. And this is how sound develops into the Word, as essentially articulate voice, whose intention it is to indicate ideas and thoughts. The purely negative moment to which music advanced now asserts itself as the wholly concrete point, the point which is mind itself, the self-conscious individual, which produces from itself the infinite expansion of its ideas and unites the same with the temporal condition of sound. Yet this sensuous element, which was still in music immediately united to emotion, is in poetry separated from the content of consciousness. Mind, in short, here determines this content for its own sake and apart from all else into the content of idea; to express such idea it no doubt avails itself of sound, but employs it merely as a sign without independent worth or substance. Thus viewed, the sound here may be just as well reproduced by the mere letter, for the audible, like the visible, is here reduced to a mere indication of mind[173]. For this reason, the true medium of poetical representation is the poetical imagination and the intellectual presentation itself; and inasmuch as this element is common to all types of art it follows that poetry is a common thread through them all, and is developed independently in each. Poetry is, in short, the universal art of the mind, which has become essentially free, and which is not fettered in its realization to an externally sensuous material, but which is creatively active in the space, and time belonging to the inner world of ideas and emotion. Yet it is precisely in this its highest phase, that art terminates, by transcending itself; it is just here that it deserts the medium of a harmonious presentation of mind in sensuous shape and passes from the poetry of imaginative idea into the prose of thought.
Such we may accept as the articulate totality of the particular arts; they are the external art of architecture, the objective art of sculpture and the subjective arts of painting, music, and poetry. Many other classifications than these have been attempted, for a work of art presents such a wealth of aspects, that it is quite possible, as has frequently been the case, to make first one and then another the basis of division. For instance, you may take the sensuous medium simply. Architecture may then be viewed as a kind of crystallization; sculpture, as the organic configuration of material in its sensuous and spatial totality; painting as the coloured surface and line, while in music, space, as such, passes over into the point or moment of time replete with content in itself, until we come finally to poetry, where the external medium is wholly suppressed into insignificance. Or, again, these differences have been viewed with reference to their purely abstract conditions of space and time. Such abstract divisions of works of art may, as their medium also may be consequentially traced in their characteristic features. They cannot, however, be worked out as the final and fundamental principle, because such aspects themselves derive their origins from a higher principle, and must therefore fall into subordination thereto.
This higher principle we have discovered in the types of art—symbolic, classical, and romantic—which are the universal stages or phases of the Idea of beauty itself.
Their relation to the individual arts in their concrete manifestation as embodiment is of a kind that these arts constitute the real and positive existence of these general art-types. For symbolic art attains its most adequate realization and most pertinent application in architecture, in which it expatiates in the full import of its notion, and is not as yet depreciated, as it were, into the merely inorganic nature dealt with by some other art. The classical type of art finds its unfettered realization, on the other hand, in sculpture, treating architecture merely as the enclosure which surrounds it, and being unable to elaborate painting and music into the wholly adequate[174] forms of its content. Finally, the romantic art-type is supreme in the products of painting and music, and likewise in poetical composition, as their preeminent and unconditionally adequate modes of expression. Poetry is, however, conformable to all types of the beautiful, and its embrace reaches them all for the reason that the poetic imagination is its own proper medium, and imagination is essential to every creation of beauty, whatever its type may be.
To sum up, then, what the particular arts realize in particular works of art, are according to their fundamental conception, simply the universal types which constitute the self-unfolding Idea of beauty. It is as the external realization of this Idea that the wide Pantheon of art is being raised; and the architect and builder thereof is the spirit of beauty as it gradually comes to self-cognition, and to complete which the history of the world will require its evolution of centuries.
