It will be thus seen that there is no mystery in one mind becoming cognizant of the thoughts of another mind, for if in sympathy, such a result is sure to follow. As a lamp gives light, because it is able to set the light medium in motion, or give off waves therein, so the brain gives off waves, or is a pulsating center in the psychic-ether. These waves go outward and form the sphere of the individual, as the waves of light go out and form the sphere of light around an incandescent body. To be recognized, they must strike against a sensitive or sympathetic brain, wherein they may be reproduced. By sympathetic, we mean one which, for want of a better term, we will say is similarly attuned. Thus, when two musical instruments are placed at some distance from each other, and one is played, if they are not attuned in harmony the other will give no response; but if they are, then when one is touched, the other answers note for note. The brain, being a pulsating center, its thoughts, as they go out in waves, have to other brains, a tangible representation. The psychic-ether, pulsating with innumerable waves, may be regarded as a universal thought atmosphere, and the sensitive brain is able to gather from it thoughts and ideas which its pulsations express. If any reliance can be placed on the observations of the most credible witnesses, whose evidence would be received on any other subject, and in law would be given power to decide on life or death, these facts of Thought Transference cannot be rejected. If they are received, they demand explanation. If thought passes from one mind to another, or, as it is often expressed, the will influences a distant person, it is self-evident that something passes from one to the other. What is this something? Facts conflict with the hypothesis of its being matter radiated from one individual to another, as light was once supposed to be transmitted. It passes too readily through vast thicknesses of solid matter, and is too instantaneous in its action, to consist of radiant particles. On the other hand, all of its phenomena show a striking relationship to light, heat and kindred forces. HOW IS THIS INFLUENCE EXERTED?--Admitting that there is a psychic-ether, in which thinking produces waves, how does one individual influence another thereby? If the brain vibrates like the strings of a musical instrument, as no two are alike, no two vibrate alike. This is more than a mere illustration. Both depend on similar laws, for the string excites vibrations in the air, which are felt by the nerves of the tympanum of the ear. Thinking creates undulations in ether, which are impressed on other minds. The string of the instrument excites similar vibrations in contiguous strings; for the atmosphere transmits the waves of sound.
