Art For Man's Sake

I have run across an interesting idea, and I want to share it with you. Ideally, you will find it interesting to, and either agree or disagree with it. I meet this notion in Paul Johnson's Art: A New History (No, I am not trying to impress anyone by saying that I am reading this huge book; in fact I am on page six). In the book he says that one of art's primary functions is to order the life of man. This idea about art is new to me. I always thought that you could argue that art is for beauty or function, but the necessity of order in our lives seems to be filled by other things. At least that is what I thought at first. But what orders our lives seem to be things of our own making. Thus the name, artefact. Almost every ordering thing in our life come from art; personal planners, calendars, clocks, etc. If we can say that language is an artefact, then the best ordering principle of human existence is from art. Where do the fine arts come in though? How do they order? I cannot answer this question. I guess I will have to get past page six.
