This theory of Mind and Substance considered as the two aspects of Something Higher, from which both have originated or emanated, will come to be regarded as the only "thinkable" proposition, in the end. And, with this idea in view, we may use the facts and experiments of the Materialists, while smiling at their theories. And, with but a slight change of words, we may turn against them their own verbal batteries. In this way, we may take Moleschott's famous statement: "_Thought is but a motion of Matter_," and render it intelligible by making it read as follows: "_Thought produces Motion in Matter_." This Finer Force of the Mind is in full evidence to those who look for it, and although it may not be registered by the scales or instruments designed to register the coarser grades of Force, still it _is_ registered in the minds of men and women, and in the actions resulting from their thoughts. These living registers of the Force respond readily to it,--and every one of us is such a register. Just as is the Force a much higher grade of Energy than the forms usually considered as comprising the entire range of Energy, so are the instruments required for its registration much higher than those used to determine the degrees of Heat, Light, Electricity, and Magnetism. It may be that the future will give us instruments adapted for the purpose--in fact it begins to look even now as if the same were forthcoming. But whether we have such mechanical instruments, or not, the living instruments give us a sufficient proof of the existence of the Force, and its operation. Well--the writer still finds himself unable to bring the book to a close. He added this chapter, to show that the property of Dynamic Thought extended to the highest development of Mind, as well as abiding in the lowest. And, now that he has ventured upon the subject, he finds himself impelled to give you a few instances of the workings and operations of that Law, in the case of Human Mental Life. And this means one more chapter--but only one, remember. The book must come to an end sometime remember. And, so we will pass over into another chapter, which will be entitled, "Thought in Action." CHAPTER XVI THOUGHT IN ACTION Without attempting to go into details, or to enter into explanations, the writer purposes taking his readers on a flying trip through the region of "Thought in Action," or "Dynamic Thought in Operation in Human Life." The details of this fascinating region must be left for another and more extended visit, in our next book (before mentioned) which will be called "_The Wonders of The Mind_." But he thinks that even this flying trip will prove of interest and instruction.
