Go out and look at any landscape … there is a sentiment, a feeling, which pervades the whole — you may call it the poetry of nature if you like — something which you cannot see, which is not material and yet is as much a part of the landscape as the trees and grass themselves. If you don't get that, you don't get anything, and your picture is nothing but a colored map. But the man who can reproduce that feeling on canvas, who can make the one who sees the picture feel as he felt, that man is an artist, and his work is a work of art.
