A. H._ More talk and less thought is expended on the subject of sex today than on almost anything else. It is a hopeful sign for the future that society in general is awakening to the far-reaching importance of the relations between the sexes, and--feeling that these relations at present leave much to be desired--is offering many suggestions for the solution of this vexed problem, even though the suggestions themselves are not always calculated to obtain the desired results. The fact that throughout much of the civilized world, women outnumber men, combined with the attitude of certain women whose lives have been passed without personal experience of sexual relations has led to the suggestion that the sex problem may be simplified in the future by the development of a neuter sex which these people think they see approaching. But this seems hardly a likely solution, for asexuality must of necessity be self-destructive, and need not, therefore, occupy us long, though just now the type does seem rather self-concious. A less fanciful, though not more satisfying, solution is that of the feminist, who, in hunting for a cure, demands for men and women alike no restraint on sexual relations beyond the immediate desires of the two people most intimately concerned, while her milder sister, the suffragette, believes that women by voting can bring about in both sexes the control of human passion. That the sexual relation interests the world is not so new a condition as we sometimes think; indeed, half unconsciously, sex has always been of paramount interest from the cradle to the grave, from the time when the child alone first nurses tenderly its doll, or in groups plays house, and at being father and mother and children. It is only the realization and open discussion of the interest which is new. Sex is the most vital thing in the world, for on it all but the lowest forms of life depend; hence the instinct of reproduction is equalled in its force by no other except, perhaps, that of self-preservation. We must think about it. Only let us think straight.
