I have in mind, for example, the pictures by the American artist, Thomas W. Dewing. They show you one or two women standing or sitting, apparently lost in reverie, while placed beside them may be a table and a vase and on the wall a mirror. If you ask me what the picture is about, I will say: Nothing. There is no subject to them in the sense that you can describe: who the girl is, why she is there, and what she is doing. So, instead of talking to you about the figures, I should try to draw your attention to the subtlety and beauty of the tonal harmony. I should recommend you to look at it with a mind as free from outside thoughts, as when you were looking at the opal. Then by degrees, perhaps, as the beauty of the tone winds itself about your imagination, you will begin to find some sentiment of beauty suggested by the girl herself.
