The further we fit her, moreover (beyond her normal capacity), for such affairs, by artificially equipping her with masculine aptitudes, the more we unfit her for her evolutionary rôle of spontaneous advance. Her chiefest values lie in the spring and the plasticity which enable her to adapt her nature to the evolutionary impulses of life inherent in her; and thereby to engender further human evolution. For this, it is important that she shall not be moulded on those firmer and more definitely prescribed lines of masculine development which are indispensable to the pioneering of material progress. Nor should her powers be equally differentiated, or similarly expended. They must be left, in far greater degree, conserved, unformulate and unadapted. Normally, she is the child of Nature, in whom (because she is the mother of the human child, who shapes to the maternal model) Nature is unfolding the type of our Perfecting Humanity. She should remain, therefore, more or less in the native and spontaneously fructifying state conducive to evolutionary unfoldment. When she adapts as closely to concrete conditions as it is imperative for man to do, not only does she exhaust the potential fertility indispensable to the further evolution and growth of racial faculty, but her powers lose that mode of flux which enables them to tide to higher levels. While man stands for Civilisation, woman stands for Nature. Generatrix of Life, she is instinct with vital impulses. And when these are not expended, as is normal, in the creation of and ministration to living and beloved beings, they generate warped, erratic and chaotic aberrations. Because, no matter to what degree she may acquire masculine characteristics and aptitudes, she remains, at core, a creature of instinct; not of reason. As a creature of instinct she is invaluable to life--because Life is moulded upon instinct. But instinct and rationalism function on different planes of mentality. To over-develop rationalism in her is to quench emotionalism in her, and the higher illumination of her Supra-conscious faculties; thus rendering her the prey of smouldering subconscious impulses which burst fitfully and mischievously into flame. For Progress, man must be always the leading half and controller in politics and civic affairs. These are his province. His sex stands for permanence and conformity--and, accordingly, for uniformity. And uniformity is the model for Civilisation, making as it does for justice and the common good. Woman's non-conformability adapts her admirably to the personal relations of life, but not to the political. Man builds institutions and administers them by more or less rigid impersonal rule. Woman transforms them into homes, and humanises them by individual concessions and exceptions.
