To meet this, it is necessary to show that our highly specialized motherhood is not so advantageous as believed; that it is below rather than above the efficacy of motherhood in other species; that its deficiency is due to the sexuo-economic relation; that the restoration of economic freedom to the female will improve motherhood; and, finally, to indicate in some sort the lines of social and individual development along which this improvement may be “practically” manifested. In approaching this subject, we need something of special mental preparation. We need to realize that our ideas upon this theme are peculiarly colored by prejudice, that in no other field of thought are we so blinded by our emotions. We have felt more on this subject than on any other, and thought less. We have also felt much on the relation of the sexes; but it has been made a subject of study, of comparison, of speculation. There are differences of feeling on the sex question, but as to motherhood none. Here and there, to be sure, some isolated philosopher, a Plato, a Rousseau, dares advance some thought on this ground; but, on the whole, no theme of commensurate importance has been so little studied. More sacred than religion, more binding than the law, more habitual than methods of eating, we are each and all born into the accepted idea of motherhood and trained in it; and in maturity we hand it down unquestioningly. A man may question the purposes and methods of his God with less danger of outcry against him than if he dare to question the purposes and methods of his mother. This matriolatry is a sentiment so deep-seated, wide-spread, and long-established as to be dominant in every class of minds. It is so associated with our religious instincts, on the one hand, and our sex-instincts, on the other, both of which we have long been forbidden to discuss,—the one being too holy and the other too unholy,—that it is well-nigh impossible to think clearly and dispassionately on the subject. It is easy to understand why we are so triple-plated with prejudice in the case.
