Such is the primordial, and, in a sense, the cosmic power of the Beautiful; a power whose very growth, whose constantly more complex nature proclaims its necessary and beneficial action in human evolution. It is the power of making human beings live, for the moment, in a more organically vigorous and harmonious fashion, as mountain air or sea-wind makes them live; but with the difference that it is not merely the bodily, but very essentially the spiritual life, the life of thought and emotion, which is thus raised to unusual harmony and vigour. I may illustrate this matter by a very individual instance, which will bring to the memory of each of my readers the vivifying power of some beautiful sight or sound or beautiful description. I was seated working by my window, depressed by the London outlook of narrow grey sky, endless grey roofs, and rusty elm tops, when I became conscious of a certain increase of vitality, almost as if I had drunk a glass of wine, because a band somewhere outside had begun to play. After various indifferent pieces, it began a tune, by Handel or in Handel's style, of which I have never known the name, calling it for myself the _Te Deum_ Tune. And then it seemed as if my soul, and according to the sensations, in a certain degree my body even, were caught up on those notes, and were striking out as if swimming in a great breezy sea; or as if it had put forth wings and risen into a great free space of air. And, noticing my feelings, I seemed to be conscious that those notes were being played _on me_, my fibres becoming the strings; so that as the notes moved and soared and swelled and radiated like stars and suns, I also, being identified with the sound, having become apparently the sound itself, must needs move and soar with them. We can all recollect a dozen instances when architecture, music, painting, or some sudden sight of sea or mountain, have thus affected us; and all poetry, particularly all great lyric poetry, Goethe's, Shelley's, Wordsworth's, and, above all, Browning's, is full of the record of such experience.
