Thought and language are to the artist instruments of an art. Vice and virtue are the artist’s materials for an art. From the point of view of form, the type of all the arts is the art of the musician. From the point of view of feelings, the actor’s craft is the type. All art is at once surface and symbol. Those who go beneath the surface do so at their peril. Those who read the symbol do so at their peril. It is the spectators, and not life, that art really mirrors.
