Arnheim regards the whole dance as a "whole beyond time" because he thinks: "Time itself (that is, the order of various components) is nothing more than an arrangement principle of order in dance, but in painting and architecture it refers to the distribution principle of all parts in space. Therefore, the essential difference between these two kinds of art media is not that one is spatial and the other is temporal. The essential difference lies in: in a dance work, the relationship between the parts is stipulated by the work itself; Painting and sculpture are not like this. When we watch a sculpture or a painting, the order of our perception is not limited by the order of the works themselves; When we watch a dance, our perceptual order is restricted by the arrangement principle of the dance itself.
