Half a century ago, Stern discussed this attribute of an artistic object and called it apparency. While art is not limited to this single end, he felt that one of its two basic functions was "to create images which by clarity and harmony of form fulfill the need for vividly comprehensible appearance." In his mind, this was an essential first step toward the expression of inner meaning.
The personal experience of most of us will testify to this persistence of an illusory image long after its inadequacy is conceptually realized. We stare into the jungle and see only the sunlight on the green leaves, but a warning noise tells us that an animal is hidden there. The observer then learns to interpret the scene by singling out "give-away" clues and by reweighting previous signals. The camouflaged animal may now be picked up by the reflection of its eyes. Finally by repeated experience the entire pattern of perception is changed, and the observer need no longer consciously search for give-aways, or add new data to an old framework. They have achieved an image which will operate successfully in the new situation, seeming natural and right. Quite suddenly the hidden animal appears among the leaves, "as plain as day."
Everything points to the conclusion that the phrase 'the language of art' is more than a loose metaphor, that even to describe the visible world in images we need a developed system of schemata.
No legislation could prevent the making of verbal pictures: God walks in the garden, He stretches out His arm, His voice shakes the cedars, His eyelids try the children of men. To forbid the making of pictures about God would be to forbid thinking about God at all, for man is so made that he has no way to think except in pictures. But continually, throughout the history of the Jewish-Christian Church, the voice of warning has been raised against the power of the picture-makers: “God is a spirit”, “without body, parts or passions”; He is pure being, “I AM THAT I AM”.
The fact is, that all language about everything is analogical; we think in a series of metaphors. We can explain nothing in terms of itself, but only in terms of other things.
