CHAPTER 13 THE BRAIN

THE GREATEST FORCES ARE "INTANGIBLE"

The depression brought the world to the very border-line of understanding of the forces which are intangible and unseen. Through the ages which have passed, man has depended too much upon his physical senses, and has limited his knowledge to physical things, which he could see, touch, weigh, and measure.

We are now entering the most marvelous of all ages-an age which will teach us something of the intangible forces of the world about us. Perhaps we shall learn, as we pass through this age, that the "other self" is more powerful than the physical self we see when we look into a mirror.

Sometimes men speak lightly of the intangibles- the things which they cannot perceive through any of their five senses, and when we hear them, it should remind us that all of us are controlled by forces which are unseen and intangible.

The whole of mankind has not the power to cope with, nor to control the intangible force wrapped up in the rolling waves of the oceans. Man has not the capacity to understand the intangible force of gravity, which keeps this little earth suspended in mid-air, and keeps man from falling from it, much less the power to control that force. Man is entirely subservient to the intangible force which comes with a thunder storm, and he is just as helpless in the presence of the intangible force of electricity- nay, he does not even know what electricity is, where it comes from, or what is its purpose!

Nor is this by any means the end of man's ignorance in connection with things unseen and intangible. He does not understand the intangible force (and intelligence) wrapped up in the soil of the earth- the force which provides him with every morsel of food he eats, every article of clothing he wears, every dollar he carries in his pockets.

THE DRAMATIC STORY OF THE BRAIN

Last, but not least, man, with all of his boasted culture and education, understands little or nothing of the intangible force (the greatest of all the intangibles) of thought. He knows but little concerning the physical brain, and its vast network of intricate machinery through which the power of thought is translated into its material equivalent, but he is now entering an age which shall yield enlightenment on the subject. Already men of science have begun to turn their attention to the study of this stupendous thing called a brain, and, while they are still in the kindergarten stage of their studies, they have uncovered enough knowledge to know that the central switchboard of the human brain, the number of lines which connect the brain cells one with another, equal the figure one, followed by fifteen million ciphers.

"The figure is so stupendous," said Dr. C. Judson Herrick, of the University of Chicago, "that astronomical figures dealing with hundreds of millions of light years, become insignificant by comparison.

It has been determined that there are from 10,000,000,000 to 14,000,000,000 nerve cells in the human cerebral cortex, and we know that these are arranged in definite patterns. These arrangements are not haphazard. They are orderly. Recently developed methods of electro-physiology draw off action currents from very precisely located cells, or fibers with micro-electrodes, amplify them with radio tubes, and record potential differences to a millionth of a volt."

It is inconceivable that such a network of intricate machinery should be in existence for the sole purpose of carrying on the physical functions incidental to growth and maintenance of the physical body. Is it not likely that the same system, which gives billions of brain cells the media for communication one with another, provides, also the means of communication with other intangible forces?
