3. In proportion as the collision portrayed by art is comprehensive, and a type of all collisions in the universe, is it a high work of art. If, then, the collision is on a small scale, and between low spheres, it is not a high work of art. 4. But whether the collision presented be of a high order or of a low order, it bears a general resemblance to every other collision—the Infinite is always like itself in all its manifestations. The lower the collision, the more it becomes merely symbolical as a work of art, and the less it adequately presents the Infinite. Thus the lofty mountain peaks of Bierstadt, which rise up into the regions of clearness and sunshine, beyond the realms of change, do this, only because of a force that contradicts gravitation, which continually abases them. The contrast of the high with the low, of the clear and untrammelled with the dark and impeded, symbolizes, in the most natural manner, to every one, the higher conflicts of spirit. It strikes a chord that vibrates, unconsciously perhaps, but, nevertheless, inevitably. On the other hand, when we take the other extreme of painting, and look at the “Last Judgment” of Michael Angelo, or the “Transfiguration” of Raphael, we find comparatively no ambiguity; there the Infinite is visibly portrayed, and the collision in which it is displayed is evidently of the highest order. 5. Art, from its definition, must relate to Time and Space, and in proportion as the grosser elements are subordinated and the spiritual adequately manifested, we find that we approach a form of art wherein the form and matter are both the products of spirit. Thus we have arts whose matter is taken from (_a_) _Space_, (_b_) _Time_, and (_c_) _Language_ (the product of Spirit). Space is the grossest material. We have on its plane, I. Architecture, II. Sculpture, and III. Painting. (In the latter, color and perspective give the artist power to represent distance and magnitude, and internality, without any one of them, in fact. Upon a piece of ivory no larger than a man’s hand a “Heart of the Andes” might be painted.) In Time we have IV. Music, while in Language we have V. Poetry (in the three forms of Epic, Lyric, and Dramatic) as the last and highest of the forms of Art.
