We may reasonably conclude, therefore, that there were only a few men in primeval days who performed any acts that entitle them to individual recognition; and as the only records that have come down to us indicate that the most important acts were the inventing of certain implements, we seem forced to conclude that most of the recognition accorded to individuals of primeval days may be limited to a very small number, and they inventors.

Who they were, and where and when they lived, is not known and probably never will be. For countless centuries their names and personalities have been forgotten as wholly as those of many beasts. But maybe other achievements like those that have exposed the history of certain Oriental kings and wise men to our knowledge, will some day tell us who were the inventors who started the march of human progress, and pointed out the road that it should follow.

Yet, if we infer the probable conditions of the remote past from the conditions of the present and recent past, we shall have to conclude that, while the names and deeds of prehistoric rulers may some day become known to us, and even the names of authors, poets and song singers, the names of the original inventors will be forever hid. For inventors have ever been depreciated in their day; even at the present time, despite the known facts as to what inventions and inventors have done for every one of us, the inventor as an inventor is lightly regarded, and so are his inventions. So are his inventions until they have ceased to be regarded as inventions, and have been accepted as constituent parts of the machine of civilization. By that time the inventor has often been forgotten.

The Age of Iron succeeded the Age of Bronze in the countries from which we have inherited our civilization; but in Africa bronze does not seem to have been discovered until after iron was. Iron being an element like copper, and not an alloy of two metals like bronze, it seems probable that its discovery, like that of copper, followed the act of heating stones with fire. The coming of iron seems due therefore to discovery rather than to invention; but yet the mere discovery that a very hard substance had been accidentally produced would of itself have brought forth no fruit. One is almost forced to infer from probability that the fact must have become known to many men, but only as a plain and uninteresting fact. Finally, some man realized that that hard substance was superior to bronze for making weapons, and then set to work to ascertain exactly what kinds of stone it could be gotten from, and exactly what process gave the best results.

To us who have been carefully taught the facts known at the present day, and whose minds have been trained by logic and mathematics to reason from effect to cause, and to construct frameworks of cause wherefrom to gain effects, it seems that anyone who noted that the hard substance which we call iron came from heating certain stones, would immediately invent a process for making iron in quantities. But prehistoric man had no knowledge whatever save that coming from his own observation and the oral teachings of the wise men; mathematics and logic did not exist; and the only training given him was in those simple arts of hunting, fishing, field tilling, etc., by which he earned his livelihood. For a mind so untrained and ignorant to leap from the simple noting of the accidental production of the metal to a realization of its value, then to a correct inference as to the possibility of producing it at will, then to a correct inference as to the method of producing it, and then to devising the method and actually producing iron at will, suggests a reasoning intelligence of an order exceedingly high.

Nevertheless, the art of making iron may have originated not so much from effort as from inspiration; the process may have been less one of reasoning than one of imagination, less one of construction than one of invention. In fact, when we realize that imagination is almost wholly a pure gift (like beauty, or artistic genius or a singing voice) while the reasoning and constructive faculties require long education, we may reasonably conclude that the production of iron and of all the metals and processes in prehistoric times, was probably attributable mainly to invention.

The crowning invention of prehistoric man was that of writing; for it lifted him out of his dependence on oral teachings, with their liability to error and forgetfulness, into a condition in which the facts and experiences of life, and the reasons for failure or success, could be put into permanent form, and supply sure bases from which to start on any line of progress in the future.

The production of the art of writing seems to have been a pure invention, and it has always been so regarded. Nothing resembling writing is to be found in nature; nowhere do we see in nature any effort to preserve any records of any kind. How man, or a man, was led to invent writing we can only imagine, for we cannot ascertain. When we realize, however, how entirely novel an undertaking the production of writing was, and that there is no process of mere reasoning by which a man could arrive at a decision to produce it, we seem forced to conclude that it must have been caused by one of those inexplicable conceptions that imagination puts into the mind, and that constitute an inspiration, coming from the Great Outside and its ruler, the Almighty.

In fact, if one ponders the history and teachings of the Christian religion (in truth of all religions), and notes that the revelations on which they are believed to have been founded seem to have come unbidden to certain men as inspirations from On High, he must realize how similar are the conceptions that come to inventors in a field less spiritual, but yet actual. For in the case of each basic invention, an idea seems to have come unbidden to the mind, and grown and developed there.

The first writing was what we call picture writing, in which representations in outline of well-known objects were scratched with a hard point on some softer substance. This form of writing probably began in the Old Stone Age. It continued for different lengths of time among different peoples, as have all other characteristics of any stage of civilization; and it is practiced in some degree by some peoples even now. In fact, one might with reasonableness declare that many of the illustrations used in books and magazines and papers, many of the paintings and drawings that adorn our walls, and many of the moving pictures in our places of amusement convey messages by means of pictures, and are therefore forms of picture writing.
