The assertion that art is thus involved with need seems for the moment to run counter to the usual conception, which regards art as a product of leisure, a luxury, and the result not of labor but of play. Art in its higher forms becomes more and more purely the expression of emotion, the un-trammeled record of the artist's spiritual experience. It is only when physical necessities have been met or ignored that the spirit of man has free range. But the maker who adds decoration to his bowl after he has moulded it is just as truly fulfilling a need--the need of self-expression--as he fulfilled a need when he fashioned the bowl in the first instance in order that he might slake his thirst. Art is not superadded to life,--something different in kind. All through its ascent from its rudimentary forms to its highest, from hut to cathedral, art is coordinate with the development of life, continuous and without breach or sudden end; it is the expression step by step of ever fuller and ever deeper experience. Creation, therefore, follows upon the consciousness of need, whether the need be physical, as with the traveler, or spiritual, as with the painter; from physical to spiritual we pass by a series of gradations. At their extremes they are easy to distinguish, one from the other; but along the way there is no break in the continuity. The current formula for art, that art is the utterance of man's joy in his work, is not quite accurate. In the act of creation the maker finds the expression of himself. The man who decorates a bowl in response to his own creative impulse is expressing himself. The painter who thrills to the wonder and significance of nature is impelled to expression; and his delight is not fully realized and complete until he has uttered it. Such art is love expressed, and the artist's work is his "hymn of the praise of things." But the joy for both the potter and the painter, the joy which is so bound up with art as to partake of its very essence, is the joy which attends self-expression and the satisfaction of the need.
