Chapter XIII: Speech and Fire

A hundred thousand years ago, among our ancestors, who then were only inarticulate mammals, living in trees and caves, one of them by himself, or a little group of them together, hit upon the use of articulate vocal signs as a means of conveying to his mates his needs, his fears, his desires and threats. It was probably by a happy fluke that he hit upon this use, or by some transcendent flash of insight due to a spontaneous variation of ability above that of the average ape; or else some unusual stress of hunger or danger of attack drove even a mediocre individual to an unwonted exercise of ingenuity. In any case, by inventing articulate speech, he brought into existence a new species of mammal--man. I must leave to your imagination the thousand transforming effects of this new device for communicating perceptions, feelings, and intentions. The speaking ape stood to his own species, and through them to other kinds of animals and to the material universe, in a different relation from that in which the speechless stood. The power of combined action among the members of any group became immeasurably greater than it had previously been. A social unity of will was possible that could never have existed on earth hitherto. For all we know, thirty thousand years may have passed away before any other event occurred among human beings comparable in practical importance to the invention of spoken language. This, however, was all the time being gradually perfected under the stress of new experiences in general and of trying predicaments in particular.

Then, in the fulness of time, and once more by a happy fluke, or by a stroke of spontaneous genius, or under the pressure of some unprecedented danger, or through the educative influence of some new order of experience, one of the speaking apes hit upon the use of fire, and thereby introduced a new era in the advancement of man. Practically infinite was the increase of man's new mastery over Nature. Into temperate and even icy regions he could now penetrate and, as it were, create around him a little temporary zone of tropical warmth. With speech had come social unity; with fire at man's disposal came mastery over matter. But the unity thereby suffered a change. With the invention of means of creating artificial warmth the social homogeneity of the tribe began to be broken. Whoever controlled fire controlled the rest of his group, since no other way for the tribal appropriation of the blessings of regulated fire was possible among talking apes, except that one individual, or a very few, should assume the office of owner of the sticks or flints for igniting the fire, and should become dispenser of the flame. The group thus was divided into the controller and the controlled, the owner and the owned, the master and the man, the governor and the governed, the chief and his followers.
