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.
"Because this is a garden where things can be left out at night without being stolen, we're going to 'furnish' the garden with French café chairs that won't be secured in the ground, so people can move them to wherever they want to sit...It's like with the chairs being totally casual and relaxed and comfortable. They set a tone. There's things that you have to do to get the right feel, where it's all already there, but then, you know, 'Bing!' – there's a moment of recognition." The patterning of chairs pulled together in different ways by successive waves of visitors over the course of the day becomes an index of the shifting patterns of people that sit in a variety of arrangements to facilitate conversations and other intersubjective alignments, or simply to allow for a moment of private contemplation free from contact with others.
