Or will you choose the universe of the subconscious, our racial past locked up in the secret chambers of our mind? Or will you choose the universe of the superconscious, the infinity of genius manifested in the arts? By the device of art man not merely creates new life, he tests it, he weighs it and measures it, he tries experiments with it, as the physicist with the molecule and the astronomer with light. He finds out what works, and what does not work, and so develops his moral and spiritual muscles, training himself for his task as maker of life. Written words can give but a feeble idea of the wonders that are found in these enchanted regions of the mind. Here are palaces of splendor beyond imagining, here are temples with sacred shrines, and treasure-chambers full of gold and priceless jewels. Into these places we enter as Aladdin in the ancient tale; we are the masters here, and all that we see is ours. He who has once got access to it--he possesses not merely the magic lamp, he possesses all the wonderful fairy properties of all the tales of our childhood. His is the Tarnhelm and the magic ring which gives him power over his foes; his is the sword Excalibur which none can break, and the silver bullet which brings down all game, and the flying carpet upon which to travel over the earth, and the house made of ginger-bread, and the three wishes which always come true, and the philter of love, and the elixir of youth, and the music of the spheres, and--who knows, some day he may come upon heaven, with St. Peter and his golden key, and the seraphim singing, and the happy blest conversing! PART TWO THE BOOK OF THE BODY CHAPTER XVIII THE UNITY OF THE BODY (Discusses the body as a whole, and shows that health is not a matter of many different organs and functions, but is one problem of one organism.) The reader who has followed our argument this far will understand that we are seldom willing to think of the body as separate from the mind. The body is a machine, to be sure, but it is a machine that has a driver, and while it is possible for a sound machine to have a drunken and irresponsible driver, such a machine is not apt to remain sound very long. Frequently, when there is trouble with the machine, we find the fault to be with the driver; in other words, we find that what is needed for the body is a change in the mind. If you wish to have a sound body, and to keep it sound as long as possible, the first problem for you to settle is what you want to make of your life; you must have a purpose, and confront the tasks of life with energy and interest. What is the use of talking about health to a man who has no moral purpose? He may answer--indeed, I have heard victims of alcoholism answer--"Let me alone. I have a right to go to hell in my own way."
