Hybrid Humanity is still amphibious; a creature living between two planes, the Without and the Within, the Material and the Spiritual. And like all amphibious creatures, the human species is, in a measure, clumsy and imperfect. Because while fitted still with organs and faculties that have adapted to a lower plane, it possesses likewise organs and faculties that are adapting to a higher. Its powers thus handicapped by requiring to engender the vital potential and the developmental power to equip it with two orders of implement, neither order has attained perfection of construction or of function. And both ministering to the requirements of the other, necessarily hamper the operations and mask the characteristics of the other. The two sexes are making all the while for higher development, each along routes of its contrary trend. Man develops human faculty in the direction of the Outer and material plane of Being. Woman develops it in the direction of the Inner and psychical plane. Man transmits to woman a brain-hemisphere and powers ever further increased and intensified in their relation to the concrete. Woman transmits to man a brain-hemisphere ever further indrawn and illumined in respect of the emotional and intrinsic. Woman's brain-hemisphere, adapting to its concrete fellow, becomes increasingly empowered to manifest, upon the outer plane, its own essential Woman-traits in Life and Consciousness. Man's brain-hemisphere, adapting to its diviner fellow, becomes increasingly illumined and inspired thereby to leaven and exalt its concrete outlook and activities. Man's brain, by way of its responsive adaptation to the brain of woman interior to it in the zone of Mind, becomes thus ever more sympathetically intelligent, or intuitive, in respect of human life and conditions, of Science and the Arts; while losing nothing of its Dominance and concrete power, but interpreting its operations in terms of a profounder and a nobler Chivalry. Woman's brain becomes ever more intelligently sympathetic and practically helpful; losing nothing of its Recessiveness, or emotional impulse, but, on the contrary, intensifying all its Woman-attributes by extending the range and the operations of these in terms of a profounder and a nobler Altruism. * * * * * Because of their hybrid constitution, there is necessarily a borderland, alike of faculty and function, wherein the organisation and the characteristics of the sexes merge and approximate one another's trend and traits. This borderland represents, however, the crudest and least differentiated department of the personal and mental powers of both. It is a zone of Neuterdom, and marks a grade of rudimentary organisation in which the Sex-characteristics have not yet sufficiently diverged in development, as clearly and finely to differentiate themselves as traits of pure and unalloyed type.
