This tendency, of which the demand for chickens is a rudimentary manifestation, is the basis of all appreciation. The artist's revelation of the import of life we can receive and understand only as we have felt a little of that import for ourselves. Color is meaningless to a blind man, music does not exist for the deaf. To him who has never opened his eyes to behold the beauty of field and hill and trees and sky, to him whose spirit has not dimly apprehended something of that eternal significance of which these things are the material visible bodying forth, to such a the work of the master is only so much paint and canvas. The task of the appreciator, then, is to develop his capacity to receive and enjoy. That capacity is to be trained by the exercise of itself. Each new harmony which he is enabled to perceive intensifies his power to feel and widens the range of his vision. The more beauty he apprehends in the world, so much the more of universal forces he brings into unity with his own personality. By this extension of his spirit he reaches out and becomes merged in the all-embracing life. If the conception be true that a supreme unity, linking all seemingly chaotic details, ultimately brings them into order, and that this unity, which is spiritual, penetrates every atom of matter, fusing everything and making all things one; then the appreciator will realize that the significance of art is for the spirit The beauty which the artist reveals is but the harmony which underlies the universal order; and he in his turn must apprehend that beauty spiritually. From this truth it follows that the condition of aesthetic enjoyment, or in other words the appreciation of beauty, is detachment of spirit and remoteness from practical consequences. The classic illustration of the truth is the saying of Lucretius, that it is sublime to stand on the shore and behold a shipwreck. It is sublime only as one's personal interests and feelings are not engaged. It would not be sublime if it were possible for the spectator to aid in averting the catastrophe; it would not be sublime if one's friends were aboard the ship. One is able to appreciate beauty only as one is able to detach one's self from what is immediate and practical, and by virtue of this detachment, to apprehend the spiritual significance. The sublimity of the shipwreck lies in what it expresses of the impersonal might of elemental forces and man's impotence in the struggle against nature. That sublimity, which is one manifestation of beauty, is of the spirit, and by the spirit it must be apprehended.
