It is in the twenties that the actual momentum of life begins to slacken, and it is a simple soul indeed to whom as many things are significant and meaningful at thirty as at ten years before. At thirty an organ-grinder is a more or less moth-eaten man who grinds an organ--and once he was an organ-grinder! The unmistakable stigma of humanity touches all those impersonal and beautiful things that only youth ever grasps in their impersonal glory. A brilliant ball, gay with light romantic laughter, wears through its own silks and satins to show the bare framework of a man-made thing--oh, that eternal hand!--a play, most tragic and most divine, becomes merely a succession of speeches, sweated over by the eternal plagiarist in the clammy hours and acted by men subject to cramps, cowardice, and manly sentiment.
