The aim of art is insight, understanding of the essential life of feeling. But all understanding requires abstraction. The abstractions which literal discourse makes are useless for this particular subject-matter, they obscure and falsify rather than communicate our ideas of vitality and sentience. Yet there is no understanding without symbolization, and no symbolization without abstraction. Anything about reality, that is to be expressed and conveyed, must be abstracted from reality. There is no sense in trying to convey reality pure and simple. Even experience itself cannot do that. What we understand, we conceive, and conception always involves formulation, presentation, and therefore abstraction.
