The so-called visual arts (painting, sculpture, architecture) produce concrete, perceptually available entities and make them convey an abstract, conceptual meaning. . . .
The visual arts do not deal with the sensory field of awareness as such, but with the sensory field as perceived by a conceptual consciousness.
The sensory-perceptual awareness of an adult does not consist of mere sense data (as it did in his infancy), but of automatized integrations that combine sense data with a vast context of conceptual knowledge. The visual arts refine and direct the sensory elements of these integrations. By means of selectivity, of emphasis and omission, these arts lead man’s sight to the conceptual context intended by the artist. They teach man to see more precisely and to find deeper meaning in the field of his vision.
It is a common experience to observe that a particular painting — for example, a still life of apples — makes its subject “more real than it is in reality.” The apples seem brighter and firmer, they seem to possess an almost self-assertive character, a kind of heightened reality which neither their real-life models nor any color photograph can match. Yet if one examines them closely, one sees that no real-life apple ever looked like that. What is it, then, that the artist has done? He has created a visual abstraction.
He has performed the process of concept-formation — of isolating and integrating — but in exclusively visual terms. He has isolated the essential, distinguishing characteristics of apples, and integrated them into a single visual unit. He has brought the conceptual method of functioning to the operations of a single sense organ, the organ of sight.
