My art, what do you want to say about it? Do you think you can explain the merits of a picture to those who do not see them?... I can find the best and clearest words to explain my meaning, and I have spoken to the most intelligent people about art, and they have not understood; but among people who understand, words are not necessary, you say humph, he, ha and everything has been said.
