It is not that these races are inferior to our own, they are simply different; and however superficial the differences, they are just the sort of differences that cause social friction.  Precisely the same argument would apply to the exodus of Americans and Europeans to Asiatic countries.  A certain amount of intermingling of students, travelers, missionaries, traders, is highly beneficial, in the exchange of ideas and manners it stimulates; that the main racial stocks should remain apart, on their several continents, in that mutual respect and brotherhood that the superficial repugnancies of too close contact tend to destroy.  The plan suggested at the close of the preceding paragraph would sufficiently avert these undesirable racial migrations.

IV.  The woman-movement?  The demand of women for a larger life and a recognition from men of their full equality has found expression recently, not only in the hysterical and criminal acts of British suffragettes, but in many soberer revolts against the traditional assignment of duties and privileges.  We may agree at once in deploring the exclusion of women from any rights and opportunities which are not inconsistent with a wise division of labor, and that patronizing air of superiority shown toward them by so many men-a condescension not incompatible with tenderness and chivalry.  Theirs has been the repressed and petted sex.  Yet there are no adequate grounds for supposing that men are, on an average, really abler or saner or more reasonable naturally than women; that they are, indeed, in any essential sense different, except for the results of their different education and life, and such divergences as the differentiation of sex itself involves including an average greater physical strength.[Footnote:  But cf.  Munsterberg, Psychology and Social Sanity, p. 195] Men and women are naturally equals; with equally good training they can contribute almost equally to the world’s work; they have an equal right to education, a useful vocation, and the free pursuit of happiness.  But equal rights do not necessarily imply identical duties; there is a certain division of labor laid down by nature.  Women alone can bear children, mothers alone can properly rear them; no incubators and institutions can supply this fundamental need.  If women, in their eagerness to compete with men in other occupations, neglect in any great numbers this most difficult and honorable of all vocations, there will be a dangerous decline in the numbers and the nurture of coming generations.  Moreover, if homes are not to be supplanted by boarding houses and hotels, the great majority of women must stay at home and do the work which makes a home possible.  Home making and child rearing are the duties that always have been and always will be the lot of most women; and they are duties too exacting to permit of being conjoined with any other vocation.
