That music, by and of itself, cannot express the intellectual element in the beautiful dream-images of art with precision, is a palpable truth. Yet, by its imperial dominion over the sphere of emotion and sentiment, the connection of the latter with complicated mental phenomena is made to bring into the domain of tone vague and shifting fancies and pictures. How much further music can be made to assimilate to the other arts in directness of mental suggestion, by wedding to it the noblest forms of poetry, and making each the complement of the other, is the knotty problem which underlies the great art-controversy about which this article concerns itself. On the one side we have the claim that music is the all-sufficient law unto itself; that its appeal to sympathy is through the intrinsic sweetness of harmony and tune, and the intellect must be satisfied with what it may accidentally glean in this harvest-field; that, in the rapture experienced in the sensuous apperception of its beauty, lies the highest phase of art-sensibility. Therefore, concludes the syllogism, it matters nothing as to the character of the libretto or poem to whose words the music is arranged, so long as the dramatic framework suffices as a support for the flowery festoons of song, which drape its ugliness and beguile attention by the fascinations of bloom and grace. On the other hand, the apostles of the new musical philosophy insist that art is something more than a vehicle for the mere sense of the beautiful, an exquisite provocation wherewith to startle the sense of a selfish, epicurean pleasure; that its highest function--to follow the idea of the Greek Plato, and the greatest of his modern disciples, Schopenhauer--is to serve as the incarnation of the true and the good; and, even as Goethe makes the Earth-Spirit sing in "Faust"-- "'Tis thus ever at the loom of Time I ply, And weave for God the garment thou seest him by"--
