Although the endowment by art of sensuous shape is not in this respect accidental, yet on the other hand it is not the highest mode of grasping the spiritually concrete. Thought is a higher mode of presentment than that of the sensuous concrete. Though abstract in a relative sense; yet it must not be one-sided, but concrete thinking, in order to be true and rational. The extent to which a definite content possesses for its appropriate form sensuous artistic representation, or essentially requires, in virtue of its nature, a higher and more spiritual embodiment is a question of difference exemplified at once if we compare the Greek gods with God as conceived under Christian ideas. The Greek god is not abstract, but individual, and is in close association with the natural human form. The Christian God is also, no doubt, a concrete personality, but under the mode of pure spiritual actuality, who is cognized as Spirit and in Spirit[137]. His medium of determinate existence is therefore essentially knowledge of the mind and not external natural shape, by means of which His representation can only be imperfect, and not in the entire depths of His idea or notional concept. Inasmuch, however, as it is the function of art to represent the Idea to immediate vision in sensuous shape and not in the form of thought and pure spirituality in the strict sense, and inasmuch as the value and intrinsic worth of this presentment consists in the correspondence and unity of the two aspects, that is the Idea and its sensuous shape, the supreme level and excellence of art and the reality, which is truly consonant with its notion, will depend upon the degree of intimacy and union with which idea and configuration appear together in elaborated fusion. The higher truth consequently is spiritual content which has received the shape adequate to the conception of its essence; and this it is which supplies the principle of division for the philosophy of art. For before the mind can attain to the true notion of its absolute essence, it is constrained to traverse a series of stages rooted in this very notional concept; and to this course of stages which it unfolds to itself, corresponds a coalescent series, immediately related therewith, of the plastic types of art, under the configuration whereof mind as art-spirit presents to itself the consciousness of itself[138].
