Keely demonstrates the harmony of this "distinct idea" throughout creation, and shows us that "the sun is the visible effluence and agent, earthward, of the Being without whose prior design and decree there would be no order and no systematic rule on earth," as well as that in "the universal ether" we find the link between mind and matter. "There is more of heaven than of earth, in all terrestrial things; more of spirit than of matter in what are termed material laws." Lange, with prophetic tongue, says that this age of materialism may prove to be but the stillness before the storm which bursts from unknown gulfs to give a new shape to the world. Inch by inch, step by step, physical science has marched towards its desired goal--the verge of physical nature, says Alcott. When it was thought that the verge was reached, that the mysteries which lay beyond were for ever barred to mortals by the iron gate of death, then the discoveries of Faraday, Edison, and Crookes pushed further away the chasm which separates the confessedly knowable from the fancied unknowable, and whole domains previously undreamt of were suddenly exposed to view. Not long since, Canon Wilberforce asked Keely what would become of his discovery and his inventions in case of his death before they became of commercial value to the public. Keely replied that he had written thousands of pages, which he hoped would, in such an event, be mastered by some mind capable of pursuing his researches to practical ends; but in the opinion of the writer, there is no man living who is fitted for this work. Diogenes of Apollonia identified the reason that regulated the world with the original substance, air. Keely teaches that "the original substance" is ether, not air; and that the world is regulated through this ether by its Creator. There are many molecules which contain no air--not one molecule that does not contain the one true "original substance," ether. Up to 1888 Keely was still pursuing the wrong line of research, still trying to construct an engine which could hold the ether in "a rotating circle of etheric force;" still ignorant of the impossibility of ever reaching commercial success on that line. It was the end of the year before he could be brought to entirely abandon his "perfect engine;" and to confine himself to researches, which he had been pursuing in connection with his repeated failures on the commercial line, to gain more knowledge of the laws which govern the operation of the force that, like a "Will-o'-the-wisp," seemed to delight in leading him astray.
