[1] Owing to an interchange of nervous strands, the right half of the brain controls the left half of the body; and the converse. Structural details which need not be considered here, but which have clearly for purpose the closer and more complex association and co-ordination of the Contrasting Traits of the two sides of the body. CHAPTER V MASCULINE MOTHERS PRODUCE EMASCULATE SONS BY MISAPPROPRIATING THE LIFE-POTENTIAL OF MALE OFFSPRING "_The truth, when it is discovered, is what every one has known._" I Mendel found that the hybrid plants resulting from his cross-breedings of Dominants with Recessives produced, when mated with similar hybrids, sex-cells of pure Dominant and sex-cells of pure Recessive types, and, moreover, a proportion of sex-cells of mixed type, corresponding to the grey rabbit-offspring of a black rabbit that has mated with a white. So too, are found among humans, four types of men and women such as might be expected under my application of Mendelian doctrine: _Homozygotes_ for Traits, or pure typical men and women--Dominant males and Recessive females, respectively; and _Heterozygotes_ for Traits, or mixed types--Dominant females and Recessive males. Of the pure Masculine type, are men who are wholly male in body, mind and bent; active, energetic, enterprising; pioneers of material progress; State-builders, city-builders, trade-builders, financiers, explorers, soldiers, men of affairs. Of the Mixed type, are men who, while being virile of body and mind, possess nevertheless a greater admixture of womanly quality than is strictly normal. These are the artists, poets, writers, doctors, priests, philanthropists. Among women also, are two kindred orders; the wholly womanly--pure unalloyed types of natural woman, wife and mother, sister, friend; and women who, while being wholly womanly too in attribute and trend, possess, nevertheless, underlying manly faculties which give broader scope and effectiveness to abstract and impersonal issues of their own sex-characteristics. These are the artists and poets and writers who present the Woman point of view. They are the Florence Nightingales, the Charlotte Brontës, Mary Somervilles; the philanthropists, reformers, born physicians, teachers, nurses, and so forth; whose part it is to mother, befriend and inspire humanity at large rather than to minister to individuals. Whose part it is, as well, to extend the tender, purifying ethics of Woman and The Home ever further and more deeply into public life, public work, and public administration.
