Her developmental arrest and her disabilities (resulting from an intensification of Recessive processes in her) are seen now to have subserved a phase of higher evolution. Nature suddenly locked the door upon her differentiating and escaping energies, in order that these might be conserved and knit into organisation. The active muscularity she has lost reappears in the new factors of symmetry and delicate modelling of limb; in repose and grace of movement. The straight, slim, boy-like lines of the hoyden girl have evolved into the curves and rounded suppleness and beauties of a woman. The girlish, agile and abrupt movements have passed into a woman's poise and grace. The unformed features of the child have become now delicately modelled; the curveless, emotionless lips have bloomed into the flower-like, rosy fullness of a woman's mouth; passionate and tender. New mystery and brilliance light her eyes. Eyes and brows are charged with potencies; with seriousness, with modesty, serenity, elusiveness. Hair and hands, voice and expression, have become transfigured by the magic of a re-creative impulse which has regenerated her whole being. So too her brain development, arrested along lines of concrete intellection, is seen to have evolved to higher, subtler forms of mentality; to be instinct with delicacy, sympathy, tact, and with that incalculable mode of supra-conscious cerebration which is intuition. In so far as she is of high, womanly type, she is now warm and emotional, sympathetic, intuitive; consciously pure, yet delicately passionate. From a crude and sexless hoyden, she has evolved into an exquisite complexity; invested all round with higher values, human and psychical. As in their earliest beginnings, however, so now again the Woman-traits manifest as Unfitnesses. Her new departure has actually undone in her much that had been achieved in physical adaptation. Biologists, observing this arrest of development in the female, have interpreted it as sign of an organisation inferior to that of the male. In point of fact, the contrary is the case. Her arrest of development along lines of masculine inherence no more proves her inferior to the male than does the human developmental arrest along lines of that tail our ape-progenitor possessed, prove the human inferior to the ape-species. This arrest of tail-development occurred first in the female, doubtless; being one of those evolutionary mutations in the direction of advance of Type which are engendered in her sex; and which are characterised by a conversion to higher potential, of differentiations in respect of adaptation to environment that have been achieved in the male. Conversion of male Fitness to female Unfitness, therefore.
