Prepositions belong to the partitives, and, with different prepositions attached to one and the same thing or noun, the human mind can step through the vast regions of thought as easily as the ether can vibrate through space. Thus the Latin scriptio, the name of a thing, a writing, gives us the following changes, according to the preposition: An Ascription is not a CONscription, by any means; nor does a conscription mean anything like a DEScription; nor is that the same thing with an INscription; nor when we PREscribe for a man are we PROscribing him; and every one of us knows, when the agent of a worthy cause enters, what the difference is between a SUBscription and a SUPERscription.
To the adverbs, however, must be given the preeminence among all human words. But even here there are gradations in rank. Thus the adverb, "Why?" may be nothing but a question of curiosity, and hence its idea may be suggested to an inquisitive monkey. But it is not so with the question, "How?" "Why?" may be answered by an affirmation, but "How?" can be answered only by a demonstration. Now, as our object is to call speech to witness as to what is in man, or, in other words, what man is himself, we will proceed to analyze the testimony of this word, "How?"
"HOW" FINDS A PLANET
First: It does not refer to anything which appears on the surface. Instead, it seeks to find the hidden and the unknown by following up one clue after another. When the astronomer, Leverrier, found that the planets Saturn and Uranus did not come to time, he asked himself how that could be. Meanwhile, the answer to any number of "hows" must have been previously demonstrated by him and by other astronomers before the movements of these great and distant heavenly bodies could be shown as not according to the clock-like regularity of planets in their courses. He reasoned that only one probable "how" could account for the facts; namely, another planet of just such a size and weight, and moving at just such a distance, would suffice thus to hold back Saturn and Uranus in their orbits. And so he calculated how large this heavenly body was, how heavy it was, and then just where it was, until, by this human but sure detective system, astronomers caught sight of Neptune—after Leverrier told them where to look for it.
But, after all, to decide how the vast heavenly bodies move in space is easy compared with finding out how to make a sewing machine go. For a needle to thread itself and then rapidly proceed to sew without the help of fingers calls for the discovery of more "hows" than are needed to explain Laplace's "Mecanique celeste." Mass and gravity suffice for the one, but only a Yankee's mind could have created the other.
We have now come to a great word—"create." A creator is a being who gives origin to things which would not exist but for his intelligent purpose and design. Now, man has simply filled this earth with his own creations, all due to himself alone and to none other, and all again by pondering the question, "How?" He began, for instance, by putting a hole through a flint hatchet, and ended with putting a hole through the Alps. In this last, an engineer stood at the foot of the great mountain and asked himself how he could tunnel it for nations to pass through. He saw a small stream dashing down the mountainside and at once found his desired "how," for he made that stream work big drills by compressed air, till the everlasting rocks themselves had to give in.
But man is an infinite creator—by which we mean that his creative capacity is limitless and inexhaustible. No sooner does he create one thing than he turns to create another thing totally different from it. A locomotive thundering past with a long train has no resemblance to a telegraph line, nor that, in turn, to a great printing press. Man coolly sets at defiance the most fundamental laws of physical science.
Thus, a heavy load of passengers, sitting in no less heavy cars, if put on a smooth inclined plane must slide down faster and faster to the bottom, or Vulcan would be confounded. But man strings a thin wire overhead, which would snap instantly if the load gave it one pull; but something which, some "how," man causes to pass along that wire, makes the trolley with its live freight go uphill faster than a horse can run.
THE ETHER ENSLAVED
And what about that mysterious ether? It can neither be seen, heard, felt, handled, smelt, nor tasted. Nevertheless, man has learned so much about its "how" that he is turning it into as menial a servant, obedient to his wishes, as he has made of electricity, the cause of sublime thunder; for man bids the ether carry his stock quotations or any other message of his to the ends of the earth.
