I am completely sure about that.
Artistic growth is, more than it is anything else, a refining of the sense of truthfulness. The stupid believe that to be truthful is easy; only the artist, the great artist, knows how difficult it is. Every child is an artist.
All art is quite useless. one can never consent to creep when one feels an impulse to soar. words do not express thoughts very well. they always become a little different immediately after they are expressed, a little distorted, a little foolish.
