  What produces these three art-forms is the changing relation between the content of art—the Idea as spirit—and its mode of presentation. The changes in this relation are in turn determined by the way in which the content of art is itself conceived. In symbolic art the content is conceived abstractly, such that it is not able to manifest itself adequately in a sensuous, visible form. In classical art, by contrast, the content is conceived in such a way that it is able to find perfect expression in sensuous, visible form. In romantic art, the content is conceived in such a way that it is able to find adequate expression in sensuous, visible form and yet also ultimately transcends the realm of the sensuous and visible.
