What I have said about bad stock seems to me to hold for the lower races of man. How many centuries, how many thousands of years, have the Kaffir [a tribe in southern Africa] or the negro held large districts in Africa undisturbed by the white man? Yet their intertribal struggles have not yet produced a civilization in the least comparable with the Aryan1 [western European]. Educate and nurture them as you will, I do not believe that you will succeed in modifying the stock. History shows me one way, and one way only, in which a high state of civilization has been produced, namely, the struggle of race with race, and the survival of the physically and mentally fitter race….
…. Let us suppose we could prevent the white man, if we liked, from going to lands of which the agricultural and mineral resources are not worked to the full; then I should say a thousand times better for him that he should not go than that he should settle down and live alongside the inferior race. The only healthy alternative is that he should go and completely drive out the inferior race. That is practically what the white man has done in North America. . . . But I venture to say that no man calmly judging will wish either that the whites had never gone to America, or would desire that whites and Red Indians were to-day living alongside each other as negro and white in the Southern States, as Kaffir and European in South Africa, still less that they had mixed their blood as Spaniard and Indian in South America. .. . I venture to assert, then, that the struggle for existence between white and red man, painful and even terrible as it was in its details, has given us a good, far outbalancing its immediate evil. In place of the red man, contributing practically nothing to the work and thought of the world, we have a great nation, mistress of many arts, and able, with its youthful imagination and fresh, untrammelled impulses, to contribute much to the common stock of civilized man....
But America is but one case in which we have to mark a masterful human progress following an inter-racial struggle. The Australian nation is another case of great civilization supplanting a lower race unable to work to the full the land and its resources.. . . The struggle means suffering, intense suffering, while it is in progress; but that struggle and that suffering have been the stages by which the white man has reached his present stage of development, and they account for the fact that he no longer lives in caves and feeds on roots and nuts. This dependence of progress on the survival of the fitter race, terribly black as it may seem to some of you, gives the struggle for existence its redeeming features; it is the fiery crucible out of which comes the finer metal. You may hope for a time when the sword shall be turned into the ploughshare, when American and German and English traders shall no longer compete in the markets of the world for their raw material and for their food supply, when the white man and the dark shall share the soil between them, and each till it as he lists [pleases). But, believe me, when that day comes mankind will no longer progress; there will be nothing to check the fertility of inferior stock; the relentless law of heredity will not be controlled and guided by natural selection. Man will stagnate….
The. . . great function of science in national life . . . is to show us what national life means, and how the nation is a vast organism subject . . . to the great forces of evolution….
There is a struggle of race against race and of nation against nation. In the early days of that struggle it was a blind, unconscious struggle of barbaric tribes. At the present day, in the case of the civilized white man, it has become more and more the conscious, carefully directed attempt of the nation to fit itself to a continuously changing environment. The nation has to foresee how and where the struggle will be carried on; the maintenance of national position is becoming more and more a conscious preparation for changing conditions, an insight into the needs of coming environments….
You will see that my view-and I think it may be called the scientific view of a nation- is that of an organized whole, kept up to a high pitch of internal efficiency by insuring that its numbers are substantially recruited from the better stocks, and kept up to a high pitch of external efficiency by contest, chiefly by way of war with inferior races, and with equal races by the struggle for trade-routes and for the sources of raw material and of food supply. This is the natural history view of mankind, and I do not think you can in its main features subvert it….
Is it not a fact that the daily bread of our millions of workers depends on their having somebody to work for? that if we give up the contest for trade-routes and for free markets and for waste lands, we indirectly give up our food-supply? Is it not a fact that our strength depends on these and upon our colonies, and that our colonies have been won by the ejection of inferior races, and are maintained against equal races only by respect for the present power of our empire? …
…. The path of progress is strewn with the wrecks of nations; traces are everywhere to be seen of the hecatombs [slaughtered remains] of inferior races, and of victims who found not the narrow way to perfection. Yet these dead people are, in very truth, the stepping stones on which mankind has arisen to the higher intellectual and deeper emotional life of today.
