THE PRIMACY OF RACE

If Nature does not wish that weaker individuals should mate with the stronger, she wishes even less that a superior race should intermingle with an inferior one; because in such a case all her efforts, throughout hundreds of thousands of years, to establish an evolutionary higher stage of being, may thus be rendered futile.

History furnishes us with innumerable instances that prove this law. It shows, with a startling clarity, that whenever Aryans have mingled their blood with that of an inferior race the result has been the downfall of the people who were the standard-bearers of a higher culture. In North America, where the population is prevalently Teutonic, and where those elements intermingled with the inferior race only to a very small degree, we have a quality of mankind and a civilization which are different from those of Central and South America. In these latter countries the immigrants--who mainly belonged to the Latin races—mated with the aborigines, sometimes to a very large extent indeed. In this case we have a clear and decisive example of the effect produced by the mixture of races. But in North America the Teutonic element, which has kept its racial stock pure and did not mix it with any other racial stock, has come to dominate the American Continent and will remain master of it as long as that element does not fall a victim to the habit of adulterating its blood.

In short, the results of miscegenation are always the following:

(a) The level of the superior race becomes lowered; (b) physical and mental degeneration sets in, thus leading slowly but steadily towards a progressive drying up of the vital sap.
