Wireless telegraphy, as a science, has been known but a comparatively short time. The laws underlying it have been in the universe perhaps, or undoubtedly, always. It is only lately that the mind of man has been able to apprehend them, and has been able to construct instruments in accordance with these laws. We are now able, through a knowledge of the laws of vibration and by using the right sending and receiving instruments, to send actual messages many hundreds of miles directly through the ether and without the more clumsy accessories of poles and wires. This much of it we know--_there is perhaps even more yet to be known_. We may find, as I am inclined to think we shall find, that thought is a form of vibration. When a thought is born in the brain, it goes out just as a sound wave goes out, and transmits itself through the ether, making its impressions upon other minds that are in a sufficiently sensitive state to receive it; this in addition to the effects that various types of thoughts have upon the various bodily functions of the one with whom they take origin. We are, by virtue of the laws of evolution, constantly apprehending the finer forces of nature--the tallow-dip, the candle, the oil lamp, years later a more refined type of oil, gas, electricity, the latest tungsten lights, radium--and we may be still only at the beginnings. Our finest electric lights of today may seem--will seem--crude and the quality of their light even more crude, twenty years hence, even less. Many other examples of our gradual passing from the coarser to the finer in connection with the laws and forces of nature occur readily to the minds of us all. The present great interest on the part of thinking men and women everywhere, in addition to the more particular studies, experiments, and observations of men such as Sir Oliver Lodge, Sir William Ramsay, and others, in the powers and forces pertaining to the inner life is an indication that we have reached a time when we are making great strides along these lines. Some of our greatest scientists are thinking that we are on the eve of some almost startling glimpses into these finer realms. My own belief is that we are likewise on the eve of apprehending the more precise _nature_ of thought as a force, the methods of its workings, and the law underlying its more intimate and everyday uses. Of one thing we can rest assured; nothing in the universe, nothing in connection with human life is outside of the Realm of Law. The elemental law of Cause and Effect is absolute in its workings. One of the great laws pertaining to human life is: As is the inner, so always and inevitably is the outer--Cause, Effect. Our thoughts and emotions are the silent, subtle forces that are constantly externalising themselves in kindred forms in our outward material world. Like creates like, and like attracts like. As is our prevailing type of thought, so is our prevailing type and our condition of life.
