To escape from such a condition the romantic type of art once more cancels that inseparable unity of the classical type, by securing a content which passes beyond the classical stage and its mode of expression. This content, if we may recall familiar ideas--is coincident with what Christianity affirms to be true of God as Spirit, in contrast to the Greek faith in gods which forms the essential and most fitting content of classical art. In Greek art the concrete ideal substance is potentially, but not as fully realized, the unity of the human and divine nature; a unity which for the very reason that it is purely _immediate_ and not wholly explicit, is manifested without defect under an immediate and _sensuous_ mode. The Greek god is the object of naïve intuition and sensuous imagination. His shape is therefore the bodily form of man. The sphere of his power and his being is individual and individually limited; and in his opposition to the individual person[147] is an essence and a power with whom the inward life of soul[148] is merely potentially in unity, but does not itself possess this unity as inward subjective knowledge. The higher stage is the _knowledge_ of this _implied_ unity, which in its latency the classical art-type receives as its content and is able to perfectly represent in bodily shape. This elevation of mere potentiality into self-conscious knowledge constitutes an enormous difference. It is nothing less than the infinite difference which, for example, separates man generally from the animal creation. Man is animal; but even in his animal functions he is not restricted within the potential sphere as the animal is, but becomes conscious of them, learns to understand them, and raises them--as, for instance, the process of digestion--into self-conscious science. By this means man dissolves the boundaries of his merely potential immediacy; in virtue of the very fact that he knows himself to be animal he ceases to be merely animal, and as mind is endowed with self-knowledge.
