The first question, therefore, which we have to ask when we have to speak of savages, is whether there is any indication of their having once reached a higher stage from which they have descended, or whether they are only just ascending from that low but healthy level which must precede every attempt at what we call civilisation. We may call both by the same name of savages, but, if we do so, we must always remember that, from an historical point of view, no two stages in civilised life can be more apart from each other than that of the retrogressive and that of the progressive savage. But even after we have laid down this broad line of demarcation, we shall by no means find it easy to catch either a progressive or a retrogressive savage _pur et simple_. If looking out for retrogressive or decaying savages, most people would naturally think of Fuegians, Tasmanians, Hottentots, Ashantis, Veddas, and Red Indians, and one of the strongest proofs of their decay would be derived from the fact that they are dying out wherever they are brought in contact with European civilisation. Now it is true that the Tasmanians have become extinct, and that several of the Red Indian tribes, too, have actually been destroyed by our civilisation. But we must not generalise too quickly. Some of these very tribes, the Red Indians,[16] seem to be recovering, seem to increase again, and to be able to hold their own against the baneful influences which threatened to destroy them. The negroes also are by no means dwindling away. On the contrary, they are increasing both in Africa and in America. We must therefore be careful before we deny the recuperative powers even of retrogressive savages, and we must look for other evidence beyond mere statistics in support of their hopeless degeneracy. Historical evidence of such gradual degeneracy is, from the nature of the case, almost impossible. We must trust, therefore, to less direct proof. I believe there is some distinct historical evidence in the case of the Central and South American races, that at the time of the arrival of Columbus and his successors civilisation had really been decaying for some time in America.[17] But in nearly all other cases we have to look out for other proofs in support of a higher antecedent civilisation possessed by tribes who, as we know them at present, have to be classed as savages. Such proofs, if they exist, must be sought for in language, religion, customs, tools, and works of art.
