In opposition to external Nature we find the _ideal_ realm of _consciousness_[19], the human soul as the medium[20] for the existence and manifestation of the Absolute. Together with this subjectivity is conjoined the multiplicity and differentiation of individuality, particularization, distinction, action, and development, that is, in general terms the full and varied world of the reality of Spirit[21], in which the Absolute is known, willed, experienced, and actively present. We may already infer from what we have indicated above that the differences under which the total content of art is differentiated are in essential consonance, both for our grasp and presentation of them, with what we have previously in the second portion of our inquiry examined as the symbolical, classical, and romantic types of art. In other words symbolic art only carries the art-process to the point of marking an affinity between content and form, instead of their identity, of only suggesting the ideal significance in itself and the content which that suggestion purports to express, in other words the external appearance[22]. It furnishes consequently the fundamental type to that specific art, whose function it is to elaborate the objective world as such, Nature's environment in the beautiful conclusion given by Art to Spirit (mind), and to image by suggestion the ideal significance of what is spiritual in this external medium. The classical Ideal, on the contrary, meets the case of the presentation of the Absolute as such, in its self-subsistent external reality, its essential self-repose, while the romantic Spirit (mind) type of art is, both in content and form, identical with the internal life of the soul, and the emotional life both in its infinite aspect and its finite particularity. It is, then, on a principle such as the above that the system of the particular arts is differentiated as follows: _First_, we have _architecture_, the beginning of all, whose foundation reposes in the very nature of its subject-matter. It is the commencement of art for this reason, that art at the start has in general terms neither discovered for the presentation of its spiritual content the adequate material, nor the forms that fully express it, and is consequently compelled to rest content in the mere _search_ after such true satisfaction, and to do so in the externality of its content and its mode of presentation. The medium of this primary art is that which is essentially unspiritual, gross matter, that is, only capable of configuration according to physical laws of gravity. Its form is the image of external Nature, united by its regularity and symmetry in the whole of a work of art to express merely an external reflection of Spirit.
