In the future, however, with an increased knowledge of the correct definition of true human races and types and with a recognition of the immutability of fundamental racial characters and of the results of mixed breeding, far more value will be attached to racial in contrast to national or linguistic affinities. In marital relations the consciousness of race will also play a much larger part than at present, although in the social sphere we shall have to contend with a certain strange attraction for contrasted types. When it becomes thoroughly understood that the children of mixed marriages between contrasted races belong to the lower type, the importance of transmitting in unimpaired purity the blood inheritance of ages will be appreciated at its full value and to bring half-breeds into the world will be regarded as a social and racial crime of the first magnitude. The laws against miscegenation must be greatly extended if the higher races are to be maintained. The language that a man speaks may be nothing more than evidence that at some time in the past his race has been in contact, either as conqueror or as conquered, with its original possessors. Postulating the Nordic origin and dissemination of the Proto-Aryan language, then in Asia and elsewhere existing Aryan speech on the lips of populations showing no sign of Nordic characters is to be considered evidence of a former dominance of Nordics now long vanished. One has only to consider the spread of the language of Rome over the vast extent of her Empire to realize how few of those who speak to-day Romance tongues derive any portion of their blood from the pure Latin stock and the error of talking about a “Latin race” becomes evident. There is, however, such a thing as a large group of nations which have a mutual understanding and sympathy based on the possession of a common or closely related group of languages and on the culture of which it is the medium. This assemblage maybe called the “Latin nations,” but never the “Latin race.” “Latin America” is a still greater misnomer as the great mass of the populations of South and Central America is not even European and still less “Latin,” being overwhelmingly of Amerindian blood. In the Teutonic group a large majority of those who speak Teutonic languages, as the English, Flemings, Dutch, North Germans and Scandinavians, are descendants of the Nordic race while the dominant class in Europe is everywhere of that blood.
