The race problem has ever been one of engrossing interest to civilized peoples. In almost every old mythology we meet with theories that were formulated to account for the existence of the different races living in the world, and for the races that were supposed to have existed for a time and became extinct. An outstanding feature of each racial myth is that the people among whom it grew up are invariably represented to be the finest type of humanity.

A widespread habit, and one of great antiquity, was to divide the races, as the world was divided, into four sections, and to distinguish them by their colours. The colours were those of the cardinal points and chiefly Black, White, Red, and Yellow. The same system was adopted in dealing with extinct races. Each of these were coloured according to the Age in which they had existence, and the colours were connected with metals. In Greece and India, for instance, the "Yellow Age" was a "Golden Age", the "White Age" a "Silver Age", the "Red Age" a "Bronze Age", and the "Black Age" an "Iron Age".

Although the old theories regarding the mythical ages and mythical races have long been discarded, the habit of dividing mankind and their history into four sections, according to colours and the metals chiefly used by them, is not yet extinct. We still speak of the "Black man", the "Yellow man", the "Red man", and the "White man". Archæologists have divided what they call the "pre-history of mankind" into the two "Stone Ages", the "Bronze Age" and the "Iron Age". The belief that certain races have become extinct as the result of conquest by invaders is still traceable in those histories that refer, for instance, to the disappearance of "Stone Age man" or "Bronze Age man", or of the British Celts, or of the Picts of Scotland.

That some races have completely disappeared there can be no shadow of a doubt. As we have seen, Neanderthal man entirely vanished from the face of the globe, and has not left a single descendant among the races of mankind. In our own day the Tasmanians have become extinct. These cases, however, are exceptional. The complete extinction of a race is an unusual thing in the history of mankind. A section may vanish in one particular area and yet persist in another. As a rule, in those districts where races are supposed to have perished, it is found that they have been absorbed by intruders. In some cases the chief change has been one of racial designation and nationality.

Crô-Magnon man, who entered Europe when the Neanderthals were hunting the reindeer and other animals, is still represented in our midst. Dr. Collignon, the French ethnologist, who has found many representatives of this type in the Dordogne valley where their ancestors lived in the decorated cave-dwellings before their organization was broken up by the Azilian and other intruders, shows that the intrusion of minorities of males rarely leaves a permanent change in a racial type. The alien element tends to disappear. "When", he writes, "a race is well seated in a region, fixed to the soil by agriculture, acclimatized by natural selection and sufficiently dense, it opposes, for the most precise observations confirm it, an enormous resistance to new-comers, whoever they may be." Intruders of the male sex only may be bred out in time.

Our interest here is with the races of Britain and Ireland, but, as our native islands were peopled from the Continent, we cannot ignore the evidence afforded by Western and Northern Europe when dealing with our own particular phase of the racial problem.

It is necessary in the first place to get rid of certain old theories that were based on imperfect knowledge or wrong foundations. One theory applies the term "Caucasian Man" to either a considerable section or the majority of European peoples. "The utter absurdity of the misnomer Caucasian, as applied to the blue-eyed and fair-haired Aryan (?) race of Western Europe, is revealed", says Ripley,[91] "by two indisputable facts. In the first place, this ideal blond type does not occur within many hundred miles of Caucasia; and, secondly, nowhere along the great Caucasian chain is there a single native tribe making use of a purely inflectional or Aryan language."

The term "Aryan" is similarly a misleading one. It was invented by Professor Max Müller and applied by him chiefly to a group of languages at a time when races were being identified by the languages they spoke. These peoples—with as different physical characteristics as have Indians and Norseman, or Russians and Spaniards, who spoke Indo-European, or, as German scholars have patriotically adapted the term, Indo-Germanic languages—were regarded by ethnologists of the "philological school" as members of the one Indo-European or Aryan race or "family". Language, however, is no sure indication of race. The spread of a language over wide areas may be accounted for by trade or political influence or cultural contact. In our own day the English language is spoken by "Black", "Yellow", and "Red", as well as by "White" peoples.

A safer system is to distinguish racial types by their physical peculiarities. When, however, this system is applied in Europe, as elsewhere, we shall still find differences between peoples. Habits of thought and habits of life exercise a stronger influence over individuals, and groups of individuals, than do, for instance, the shape of their heads, the colours of their hair, eyes, and skin, or the length and strength of their limbs. Two particular individuals may be typical representatives of a distinct race and yet not only speak different languages, but have a different outlook on life, and different ideas as to what is right and what is wrong. Different types of people are in different parts of the world united by their sense of nationality. They are united by language, traditions, and beliefs, and by their love of a particular locality in which they reside or in which their ancestors were wont to reside. A sense of nationality, such as unites the British Empire, may extend to far-distant parts of the world.
