Alas! It generally turns out that Life and Art are rather more complicated than we could wish; to understand exactly what is meant by simplification we must go deeper into the mysteries. It is easy to say eliminate irrelevant details. What details are not irrelevant? In a work of art nothing is relevant but what contributes to formal significance. Therefore all informatory matter is irrelevant and should be eliminated. But what most painters have to express can only be expressed in designs so complex and subtle that without some clue they would be almost unintelligible. For instance, there are many designs that can only be grasped by a spectator who looks at them from a particular point of view. Not every picture is as good seen upside down as upside up. To be sure, very sensitive people can always discover from the design itself how it should be viewed, and, without much difficulty, will place correctly a piece of lace or embroidery in which there is no informatory clue to guide them. Nevertheless, when an artist makes an intricate design it is tempting and, indeed, reasonable, for him to wish to provide a clue; and to do so he has only to work into his design some familiar object, a tree or a figure, and the business is done. Having established a number of extremely subtle relations between highly complex forms, he may ask himself whether anyone else will be able to appreciate them. Shall he not give a hint as to the nature of his organisation, and ease the way for our aesthetic emotions? If he give to his forms so much of the appearance of the forms of ordinary life that we shall at once refer them back to something we have already seen, shall we not grasp more easily their aesthetic relations in his design? Enter by the back-door representation in the quality of a clue to the nature of design. I have no objection to its presence. Only, if the representative element is not to ruin the picture as a work of art, it must be fused into the design. It must do double duty; as well as giving information, it must create aesthetic emotion. It must be simplified into significant form.
