"We have neglected the gift of comprehending things through our senses. Concept is divorced from percept, and thought moves among abstractions. Our eyes have been reduced to instruments with which to identify and to measure; hence we suffer a paucity of ideas that can be expressed in images and in an incapacity to discover meaning in what we see. Naturally we feel lost in the presence of objects that make sense only to undeluted vision, and we seek refuge in the more familiar medium of words. ... The inborn capacity to understand through the eyes has been put to sleep and must be reawakened." (Rudolf Arnheim: Art and Visual Perception, 1974, p. 1)
