Can this be done? I have no doubt that it can. For what is human life after all?
To a general in the battlefield, human life is a factor which, if properly used, can destroy the enemy. To an engineer human life is an equivalent to energy, or a capacity to do work, mental or muscular, and the moment something is found to be a source of energy and to have the capacity of doing work, the first thing to do, from the engineer’s point of view, is to analyse the generator with a view to discovering how best to conserve it, to improve it, and bring it to the level of maximum productivity. Human beings are very complicated energy-producing batteries differing widely in quality and magnitude of productive power. Experience has shown that these batteries are, first of all, chemical batteries producing a mysterious energy. If these batteries are not supplied periodically with a more or less constant quantity of some chemical elements called food and air, the batteries will cease to function—they will die. In the examination of the structure of these batteries we find that the chemical base is very much accentuated all through the structure. This chemical generator is divided into branches each of which has a very different rôle which it must perform in harmony with all the others. The mechanical parts of the structure are built in conformity to the rules of mechanics and are automatically furnished with lubrication and with chemical supplies for automatically renewing worn-out parts. The chemical processes not only deposit particles of mass for the structure of the generator but produce some very powerful unknown kinds of energies or vibrations which make all the chemical parts function; we find also a mysterious apparatus with a complex of wires which we call brain glands, and nerves; and, finally, these human batteries have the remarkable capacity of reproduction.
These functions are familiar to everybody. From the knowledge of other physical, mechanical and chemical phenomena of nature, we must come to the conclusion, that this human battery is the most perfect example of a complex engine; it has all the peculiarities of a chemical battery combined with a generator of a peculiar energy called life; above all, it has mental or spiritual capacities; it is thus equipped with both mental and mechanical means for producing work. The parts and functions of this marvelous engine have been the subject of a vast amount of research in various special branches of science. A very noteworthy fact is that both the physical work and the mental work of this human engine are always accompanied by both physical and chemical changes in the structure of its machinery—corresponding to the wear and tear of non-living engines. It also presents certain sexual and spiritual phenomena that have a striking likeness to certain phenomena, especially wireless phenomena, to electricity and to radium. This human engine-battery is of unusual strength, durability and perfection; and yet it is very liable to damage and even wreckage, if not properly used. The controlling factors are very delicate and so the engine is very capricious. Very special training and understanding are necessary for its control.
