The attainable, not to say the ideal, society requires an increase rather than a decrease of the differences between the sexes. The differences may be due to physical organization, but the structural divergence is but a faint type of deeper separation in mental and spiritual constitution. That which makes the charm and power of woman, that for which she is created, is as distinctly feminine as that which makes the charm and power of men is masculine. Progress requires constant differentiation, and the line of this is the development of each sex in its special functions, each being true to the highest ideal for itself, which is not that the woman should be a man, or the man a woman. The enjoyment of social life rests very largely upon the encounter and play of the subtle peculiarities which mark the two sexes; and society, in the limited sense of the word, not less than the whole structure of our civilization, requires the development of these peculiarities. It is in diversity, and not in an equality tending to uniformity, that we are to expect the best results from the race. V. Equality of races; or rather a removal of the inequalities, social and political, arising in the contact of different races by intermarriage. Perhaps equality is hardly the word to use here, since uniformity is the thing aimed at; but the root of the proposal is in the dogma we are considering. The tendency of the age is to uniformity. The facilities of travel and communication, the new inventions and the use of machinery in manufacturing, bring men into close and uniform relations, and induce the disappearance of national characteristics and of race peculiarities. Men, the world over, are getting to dress alike, eat alike, and disbelieve in the same things: It is the sentimental complaint of the traveler that his search for the picturesque is ever more difficult, that race distinctions and habits are in a way to be improved off the face of the earth, and that a most uninteresting monotony is supervening. The complaint is not wholly sentimental, and has a deeper philosophical reason than the mere pleasure in variety on this planet. We find a striking illustration of the equalizing, not to say leveling, tendency of the age in an able paper by Canon George Rawlinson, of the University of Oxford, contributed recently to an American periodical of a high class and conservative character.--["Duties of Higher towards Lower Races." By George Rawlinson. Princeton Re-view. November, 1878. New York.]--This paper proposes, as a remedy for the social and political evils caused by the negro element in our population, the miscegenation of the white and black races, to the end that the black race may be wholly absorbed in the white--an absorption of four millions by thirty-six millions, which he thinks might reasonably be expected in about a century, when the lower type would disappear altogether.
