CHAPTER VII
THE PARADOX OF SCIENCE
IN the days of the ancients, when the philosophers found themselves unable to account for any particular class of phenomena, they bundled it together and referred it to a suppositious Something that they called "The Ether." Finding this an easy way to get rid of vexatious questions, they fell into the custom—and the habit grew upon them. Soon there were a dozen or more different kind of Ethers in vogue, each explaining something else—the "something else," by the way, being things that Science now feels that it understands pretty well. These Ethers grew to be like the various "Vapors" of the ancients—a dignified term for "We don't know"—a respectable road for retreat under the semblance of an advance.
These Ethers became a scientific scandal, and caused a lax mode of thinking among students of those times. And so they were finally abolished and relegated to the scrap pile of Science, where they lay for many centuries until a comparatively recent period, when at least one of them was hauled forth, dusted, freshened up a little, and placed upon its old pedestal. This revamped Ether, referred to, was the "Ether of Aristotle." Aristotle, as we know, was a famous Greek philosopher who lived about 350 b.c.—about 2250 years ago. He was a good man and a celebrated philosopher, but was somewhat deficient in scientific knowledge. Although he knew many things, and uttered many wise thoughts, he was under the impression that the breath of Man entered the heart instead of the lungs—that the back part of the skull was empty, and so on. He was without the advantages of a modern training—which, was not his fault, however.
Well, Aristotle conceived the idea of an Universal Ether, which he thought pervaded all space, and with which he accounted for the passage of light from the sun and stars; the movements of the planets, and various other physical phenomena. It is not known whether Aristotle really believed in this Ether, or whether he merely used it as a speculative hypothesis, following the Ether Habit of his contemporaries. At any rate, his theory served its purpose—lived, flourished, declined and died—at least seemed to be dead. But its corpse was resurrected in modern times, and used to account for divers things.
This does not mean that modern thinkers really "believe" in the Universal Ether—they merely assume it as a working hypothesis until something better is offered.
Its principal modern use is to account for the transmission of Light from the Sun and Stars to the Earth. It was held that a thing could not act "where it was not," and so it became necessary to account for the transmission either by the theory that small particles of substance were thrown off from the Sun, and travelled to the Earth, or else that there was some medium of communication by means of vibrations, etc. Newton held to the first theory, but his hypothesis went down before the Ether advocates, who advanced the "wave-theory," although it seems that, like Banquo's ghost, Newton's theory will not stay down, and is now taking on a new lease of life, owing to the discovery of the Corpuscle and Radiant Matter.
The Wave-theory philosophers asserted that the Light and Heat of the Sun were thrown off in the shape of Force or Energy, and transformed into "waves" in and of a hypothetical Ether (Aristotle's own), which waves were carried to the Earth, where, meeting Substance, they were again transformed into Heat and Light.
It was known that Light and Heat travelled at the rate of 184,000 miles per second, and therefore the "waves" of the Ether were considered to have that speed. The Wave-theory seemed to fit the facts of the case better than the Newtonian Theory of Corpuscles, although the latter has always been considered as better explaining certain phenomena than the new theory. And so the Ether Wave became generally accepted, and remains so to-day, although recent discoveries are causing a disturbance in the scientific camp regarding the question.
Later it was discovered that the Electricity travelled at the same rate as Light and Heat, and the Wave-of-the-Ether theory was thus thought to have additional verification, and Electricity came under the Law and remained there until the Electron discovery, which is causing much disturbance, among those interested in the study of Electricity.
Briefly stated, the theory of the Universal Ether is this:
