Such men and women possess the characteristics of their own sex fully differentiated, but tinctured and fructified by more than a normal quotum of the characteristics of the other. They are quite normal, however, and are wholly invaluable in their contribution to the world's affairs. Admirably manly or womanly, they bear but little likeness to the hereditarily-defective or to the artificially-manufactured species--mannish women and womanish men. They deviate from the essential Man and Woman types by degrees of overlapping in the higher mental attributes. In all the main characteristics of Sex, physical, mental and functional, they are completely men and women. The abnormal mixed types are, on the contrary, more or less degenerate, structurally, functionally and mentally. These persons of natural Mixed Types are Nature's workers rather than the parents of her Races. The daily round is too restricted for them. Their abilities and bent claim wider fields. The home cannot contain them. It is too round to fit their angles. They are hampered by its reciprocities, stifled by its personal atmosphere, restive beneath its obligations. And not seldom they succeed in making homes as uncomfortable for others as they themselves find such. These Heterodox--of which mould Genius is--are indispensable to spur and quicken human progress, while adding nothing to the personal evolution of the Human Type. They advance the standards and the ethics of Humanity by creating ideals in Art, in Literature, in Politics, in Reform and Philanthropy. But only too often they fall short, in their own lives, of the standards and ideals they establish for the world at large. The Advance-guard of Faculty, they break new ground of Mind and Morale for others to cultivate. Although they themselves frequently quarrel with life, they make life in general greater and happier for their fellows. If women, they possess much of the initiative and energy, the intellect and chivalry of men. But they apply these to womanly ends. If men, they possess much of the insight and sympathy, the altruism and creativeness of women. But they devote these to manly achievements. Herbert Spencer held that Genesis (or reproductive power) and Individuation (or Self-development) exist in inverse ratio. Which is because individuation _beyond the normal_ can only be achieved by drawing upon the vital potential of offspring. Hence, these strong individualities of Mixed Type--because reproductive power is diminished in them--but seldom transmit their abilities to offspring. Genius is frequently sterile. Otherwise, its children are of inferior calibre. It is in imitation, doubtless, of the natural Mixed Types--which may be described as a normal deviation from The Normal--that the cult of the mannish woman is being cruelly and disastrously forced upon our latter-day girls and women; resulting in wholly deplorable developments.
