have received from God.

Parley P. Pratt, who, as a member of the first quorum of apostles, had every opportunity of obtaining the Prophet's views on any subject, wrote in considerable fullness on the subject of the Holy Spirit, or the light of truth:

"As the mind passes the boundaries of the visible world, and enters upon the confines of the more refined and subtle elements, it finds itself associated with certain substances in themselves invisible to our gross organs, but clearly manifested to our intellect by their tangible operations and effects." "The purest, most refined and subtle of all these substances—is that substance called the Holy Spirit." "It is omnipresent." "It is in its less refined particles, the physical light which reflects from the sun, moon and stars, and other substances; and by reflection on the eye makes visible the truths of the outward world."[A]

[Footnote A: Key to Theology, 5th ed., pp. 38-41.]

Elder C. W. Penrose, an accepted writer on Mormon doctrine, writes, "It is by His Holy Spirit, which permeates all things, and is the life and light of all things, that Deity is everywhere present. * * By that agency God sees and knows and governs all things."[A]

[Footnote A: Rays of Living Light, No. 2, p. 3.]

Such quotations, from the men intimately associated or acquainted with the early history of the Church, prove that Joseph Smith taught in clearness the doctrine that a subtle form of matter, call it ether or Holy Spirit, pervades all space; that all phenomena of nature, including, specifically, heat, light and electricity, are definitely connected with this substance. He taught much else concerning this substance which science will soon discover, but which lies without the province of this paper to discuss.

By the doctrine of the ether, it is made evident all the happenings in the universe are indelibly inscribed upon the record of nature. A word is spoken. The air movements that it causes disturbs the ether. The ether waves radiate into space and can never die. Anywhere, with the proper instrument, one of the waves may be captured, and the spoken word read. That is the simple method of wireless telegraphy. It is thus that all our actions shall be known on the last great day. By the ether, or the Holy Spirit as named by the Prophet, God holds all things in His keeping. His intelligent will radiates into space, to touch whomsoever it desires. He who is tuned aright can read the message, flashed across the ether ocean, by the Almighty. Thus, also, God, who is a person, filling only a portion of space is, by His power carried by the ether, everywhere present.

The ether of science though material is essentially different from the matter composing the elements. So, also, in Mormon theology, is the Holy Spirit different from the grosser elements. In science there is a vast distinction between the world of the elements, and that of the ether; in theology, there is an equally great difference between the spiritual and material worlds. Though the theology of Joseph Smith insists that immaterialism is an absurdity, yet it permits no overlapping of the earthly and the spiritual.

[Sidenote: Joseph Smith stated the existence of a universe-filling substance before science had generally accepted it.]

It must not be overlooked that the broad statement of this doctrine was made by Joseph Smith, at least as early as 1832, at a time when the explanation of light phenomena on the hypothesis of a universal ether was just beginning to find currency among learned men; and many years before the same hypothesis was accepted in explaining the phenomena of heat and electricity.

The idea of an influence pervading the universe is not of itself new. Poets and philosophers of all ages have suggested it in a vague, hesitating manner, without connecting it with the phenomena of nature, but burdening it with the greatest absurdity of religion or philosophy, that of immaterialism. Joseph Smith said the doctrine had been taught him by God, and gave it to the world unhesitatingly and rationally. The men of science, to whom Joseph Smith appears only as an imposter, and who know nothing of his writings, have later discovered the truth for themselves, and incorporated it in their books of learning.

Had Joseph Smith been the clever imposter that some claim he was, he probably would not have dealt in any way with the theories of the material world, at least would not have claimed revelations laying down physical laws; had he been the stupid fool, others tell us he was, his mind would not have worried itself with the fundamental problems of nature.

However that may be, it is certain that Joseph Smith, in the broad and rational statement of the existence of an omnipresent, material though subtle substance, anticipated the workers in science. In view of that fact, it is not improbable that at some future time, when science shall have gained a wider view, the historian of the physical sciences will say that Joseph Smith, the clear-sighted, first stated correctly the fundamental physical doctrine of the universal ether.

Chapter V.

THE REIGN OF LAW.

In the seventh book of the Republic of Plato[A] occurs the following passage:

[Footnote A: Golden Treasury edition, pp. 235, 236.]

[Sidenote: The realities of nature are known by their effects.]

"Imagine a number of men living in an underground cavernous chamber, with an entrance open to the light, extending along the entire length of the cavern, in which they have been confined, from childhood, with their legs and necks so shackled, that they are obliged to sit still and look straight forward, because their chains render it impossible for them to turn their heads round; and imagine a bright fire burning some way off, above and behind them, and an elevated roadway passing between the fire and the prisoners, with a low wall built along it, like the screens which conjurers put up in front of their audiences, and above which they exhibit their wonders. Also figure to yourself a number of persons walking behind the wall, and carrying with them statues of men and images of other animals, wrought in wood and stone and all kinds of materials, together with various other articles, which overtop the wall; and, as you might expect, let some of the passers-by be talking, and the others silent.

"Let me ask whether persons so confined could have seen anything of themselves or of each other, beyond the shadows thrown by the fire upon the part of the cavern facing them? And is not their knowledge of the things carried past them equally limited? And if they were able to converse with one another, would they not be in the habit of giving names to the objects which they saw before them? If their prison house returned an echo from the part facing them, whenever one of the passers-by opened his lips, to what could they refer the voice, if not to the shadow which was passing? Surely such person would hold the shadows of those manufactured articles to be the only realities."

With reference to our absolute knowledge of the phenomena of nature, this splendid comparison is as correct today as it was in the days of Plato, about 400 B. C.; we are only as prisoners in a great cave, watching shadows of passing objects thrown upon the cavern wall, and reflecting upon the real natures of the things whose shadows we see. We know things only by their effects; the essential nature of matter, ether and energy is far from our understanding.

[Sidenote: The progress of science rests on the law of cause and effect.]

In early and mediaeval times, the recognition of the fact that nature in its ultimate form is
