This teaches us that unconsciously our thought and feeling are produced upon all things we use: a place, a rock, a tree, a seat, upon the things we prepare - but in art an artist completes the music of his soul, of his mind. It is not produced automatically, it is very often a conscious effort, an effort which results in a certain effect. This shows that it is not enough to learn art, or to practice art. In order to complete art one must understand the psychology of it, through which one accomplishes the purpose of one's fife.
