Art appears in many forms. To some degree every human being is an artist, dependent on the quality of his growth. Art need not be intended. It comes inevitably as the tree from the root, the branch from the trunk, the blossom from the twig. None of these forget the present in looking backward or forward. They are occupied wholly with the fulfillment of their own existence. The branch does not boast of the relation it bears to its great ancestor the trunk, and does not claim attention to itself for this honor, nor does it call your attention to the magnificent red apple it is about to bear. Because it is engaged in the full play of its own existence, because it is full in its own growth, its fruit is inevitable.
