Tigress or savage woman, her struggle with the rough conditions of primal existence is only less fierce and less strenuous than her mate's. It demands the positive male-qualities (which manifest first in stature, strength and pugnacity) only less in degree than does his, therefore. The negative female qualities which, manifesting first in passivity and surrender, detract from her fierceness and activity, would have made for extinction of species had they not been defended by those of her fighting mate, as too by the male-traits she herself had inherited from her fighting father. They could only evolve, accordingly, precisely in proportion as they were sheltered behind the male dominant powers. The tiger shelters his tigress only during her maternal phases, however. Her cubs brought forth, suckled, reared, and thrust into the jungle to fend for themselves, she must fight her own battles for food and existence. And her brief maternal phases being all too short for more than the scantest development of female traits—which derive their fullest impulse in their exercise as mother-traits—she remains a tigress merely, and produces tiger offspring merely, because only tigerishness secures survival in her domain of life and attribute.
With the further advance of progressing species, savage woman has evolved from savage brute to savage woman by way of such increasing shelter and protection by her Dominant mate as have permitted the slow and gradual evolution of the Recessive Woman-traits in her; and thereby the evolution of the Woman-sex. Her maternal phases and the unfitnesses of these become ever more prolonged and incapacitating; her offspring demands ever longer periods of suckling, devotion and care, as both she and it rise higher in the scale of organisation. Thus, Sex has evolved in the male by response to the ever-increasing claims upon him, by the female and by offspring, of his traits of protective chivalry and intelligent effort. And Sex has evolved in the female by response to the ever-increasing claims by offspring upon her, of her traits of devotion and ministry.
The evolution of the Woman-attributes has been rendered possible only by that protection accorded by the male to the female as the due of her maternal unfitnesses; securing thus for her and for offspring a more privileged and kindlier environment. Environment which, evoking less of fight and physical stress, enabled her inherent milder, self-surrendering Recessive traits to emerge, to unfold, and to function increasingly in life and heredity.
And in the degree of her advancing evolution, the male evolved. Because, just as in her earlier hybrid constitution, the Dominant male-traits she had inherited from her father, submerging the Recessive female-traits she had inherited from her mother, made her, for long æons, more male than she was female, so now, with their progressive evolution, the Recessive female-traits not only made her ever more woman, but, transmitted in ever fuller measure to her sons, increasingly tempered, modified and humanised, the masculine fierceness and combativeness of these. Whereby were substituted arts of peace and civilisation for those of war.
Thus, with advancing Evolution, the female sex-characteristics have engendered, in both sexes, qualities of quietism and subordination, to temper those of force and aggression; amenities of gentleness, forbearance and affection, to soften assertiveness, turn the edge of strife, and fructify intelligence. Thus, human civilisation has been fostered and furthered.
In the hybrid creature that every man and woman is, are grouped two sets of Contrasting Traits, or Sex-characteristics: traits Dominant, or male, and traits Recessive, or female. And in the complex human hybrid, these traits, ever increasing in complexity of constitution and further diverging in trend, are associated in ever more close and complex poise and counterpoise as both become more intensified and intelligised.
Man is a hybrid in whom the male Dominant traits derived from his father prevail in impulse and development over the female Recessive traits derived from his mother. Woman is a hybrid in whom the maternal Recessive traits prevail in impulse and development over the male Dominant traits she has inherited from her father.
The Woman-traits (which, as said, reach their highest culmination in mother-traits), become in man paternal traits; modified mother-instincts which move him not only to love, in addition to providing for and protecting offspring, but, transfiguring all his other characteristics, move him to philanthropy, amity, tolerance and altruism in his dealings with his fellow-creatures.
CHAPTER IV
ONE SIDE OF BODY IS MALE, THE OTHER SIDE IS FEMALE
"Oh, I must feel your brain prompt mine,
Your heart anticipate my heart,
You must be just before, in fine,
See and make me see, for your part,
New depths of the Divine!"

On further applying the Principle of Duality, as operating in organisation and heredity, strangely interesting and significant developments appear.
Because, with the ever further evolution of Form and Faculty as organisms have risen higher in the scale of life, the bodies of living creatures are seen to have become further differentiated into two sides; a right and a left. Anatomically, these two sides appear identical in structure and in function, although contrary in incidence to one another. Each is incomplete and impotent without the other. Nevertheless, paralysis and other diseases show that each is, as it were, an entity totally distinct from the other. One side may be wholly helpless and insensitive while its fellow remains sound and efficient.
Complementary and supplementary each to the other, both are, in a sense, complete. Further and closer comparison of function shows, however, that although they co-operate in action, they are by no means identical in power or aptitude.
The right half of the body is, for both sexes, the active and executive half; quicker and stronger, and in all ways more efficient on the plane of physics.
The left half is, relatively, passive and inert, is responsive, mainly, to the initiative and requirements of the right half, by which its powers are overshadowed in every form of direct activity.
As with the two sides of the body, so it is with the two halves of the brain, which are at the same time the agencies of mentality and the centres for recording the sensations and for directing the movements of the two sides of the body. The brain-half which controls the right side is known as "the Leading half." It is the agent in concrete intellection, as in physical activity.
While, so far as biologists and psychologists have been able to discover, the other half of the brain is negative in function—a blank, as regards concrete intelligence and nervous or muscular initiative. In disease, it has sometimes been found to undertake, and to perform feebly and imperfectly, sundry of the duties of its active "Leading" partner. But inert and inadequate in muscular action, it is negative in intellection. It has been observed, however, that patients in whom this brain-half is diseased show signs of moral deterioration. Yet whatsoever its functions—and the fact that it does not atrophy nor degenerate in the marvellous structure and complexity which characterise brain-constitution shows that it functions duly—its operations are totally dissimilar to, and are, moreover, wholly overshadowed by those of its active, intelligent partner.
Here again, as in the two sides
