Perhaps the greatest single step ever made in the history of man’s upward progress was taken when the practice of articulate speech began. It would be contrary to all that we know of human evolution to suppose that this development was a sudden one, or that it transformed a non-human into a human species at a sudden vault. It is well known that many of the lower animals are able to communicate with one another in a way that implies at least a vague form of speech, and it has been questioned whether the higher species of apes do not actually articulate in a way strictly comparable to the vocalisation of man. Be that as it may, the clear fact remains that one species of animal did at a very remote time in the past develop the power of vocalisation in the direction of articulate speech to a degree that in course of time broadened the gap between that species and all others, till it became an impassable chasm.
Without language of an explicit kind not even the rudiments of civilisation would be possible. No one perhaps ever epitomised the value of articulate speech in a single phrase more tellingly than does Herder when he says: “The lyre of Amphion has not built cities. No magic wand has transformed deserts into gardens. Language has done it,—that great source of sociality.”
Obviously, then, could we know the history of the evolution of articulate speech it would be one of the very greatest chapters in all human records; but it is equally obvious that we can never hope to know that history except inferentially. When the dawn of history proper came, man had so long practised speaking that he had developed countless languages so widely divergent from one another that they are easily classified into several great types. From the study of these languages the philologist draws more or less valid inferences as to the later stages of linguistic growth and development. But he gains no inklings whatever as to any of those earlier developments which constituted the origin or the creation of language.
Nothing is more surprising to the student of antiquity than to find at what seems the very beginning of civilisation such monuments as the Pyramids and the great sculptures of Egypt and Mesopotamia. But a moment’s reflection makes it clear that man must have learned to house himself, as well as to clothe himself, before he can have started on that tour of conquest of the world which was so far advanced before the dawn of history. Doubtless the original home of man must have been in a tropical or subtropical climate, and he cannot well have left these pampering regions until he had made a considerable development, almost the first step of which required that he should gain the means of protecting himself from the cold. The idea of such protection once acquired, its elaboration was but a question of time. It is amazing to observe how closely, both as regards attire and building, man had approximated to the modern standards at the time when he first produced monumental or other records that have come down to us.
Quite as fundamental as the matter of housing and clothing, and even more marvellous, considered as an invention, was the recognition of the uses of fire, and the development of the methods of producing fire at will. It is conceivable that some individual man at a relatively early stage of human progress developed and elaborated this idea, becoming the actual inventor of fire as applied to human uses. If such was really the case, no greater inventor ever lived. But the wildest flight of speculative imagination does not suffice to suggest where or when this man may have lived. It cannot well be doubted, however, that the use of fire must have been well known to the earliest generations of men that attempted to wander far from the tropics. Clothed, housed, and provided with fire, man was able to undertake the conquest of all regions, but without fire he dare not have braved the winters even of the middle latitudes, to say nothing of Arctic regions.
No doubt the earliest method of producing fire practically employed was by friction of dry sticks, much after the manner still in use among certain savage tribes. Obviously the flint and steel, which for so many thousands of years was to be the sole practical means of producing fire among the civilised races, could not have come into vogue until the age of iron. The lucifer match, which was finally to banish flint and steel, was an invention of the nineteenth century.
