Community of race is a far deeper bond than community of language, education, or government. Where one political system dominates various races it forces their common culture to be external merely. This is perhaps the secret of that strange recrudescence of national feeling, apart often from political divisions, which has closely followed the French Revolution and the industrial era. The more two different peoples grow alike in externals the more conscious and jealous they become of diversity in their souls; and where individuals are too insignificant to preserve any personality or distinction of their own, they flock together into little intentional societies and factious groups, in the hope of giving their imagination, in its extremity, some little food and comfort. Private nationalities and private religions are luxuries at such a time in considerable demand. The future may possibly see in the Occident that divorce between administrative and ideal groups which is familiar in the Orient; so that under no matter what government and with utter cosmopolitanism in industry and science, each race may guard its own poetry, religion, and manners. Such traditions, however, would always be survivals or revivals rather than genuine expressions of life, because mind must either represent nature and the conditions of action or else be content to persist precariously and without a function, like a sort of ghost. [Sidenote: “Pure” races may be morally sterile.] Some races are obviously superior to others. A more thorough adjustment to the conditions of existence has given their spirit victory, scope, and a relative stability. It is therefore of the greatest importance not to obscure this superiority by intermarriage with inferior stock, and thus nullify the progress made by a painful evolution and a prolonged sifting of souls. Reason protests as much as instinct against any fusion, for instance, of white and black peoples. Mixture is in itself no evil if the two nations, being approximately equal, but having complementary gifts, can modify them without ultimate loss, and possibly to advantage. Indeed the so-called pure races, since their purity has gone with isolation and inexperience, have borne comparatively little spiritual fruit. Large contact and concentrated living bring out native genius, but mixture with an inferior stock can only tend to obliterate it. The Jews, the Greeks, the Romans, the English were never so great as when they confronted other nations, reacting against them and at the same time, perhaps, adopting their culture; but this greatness fails inwardly whenever contact leads to amalgamation.
