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.
Let us take a look at how one of these scholars or critics goes about his work. Let’s say he is going to write a commentary on a particular painting. If he is not a man of intuition, certain features will characterize his approach. First he will try to place the painting genealogically, or he will try to define the painting by assigning it to a particular school. He feels uneasy unless he succeeds in doing this.
But more than anything, he is extremely wordy. He seems incapable of speaking of beauty without innumerable layers of adjectives.
One can study an object and note its features, but that only touches the surface. A knowledge of an artwork’s properties does not lead to an understanding of its essence.
