But still, boys and girls should be kept apart as much as possible, that they may have some sort of respect and fear for the gulf that lies between them in nature, and for the great strangeness which each has to offer the other, finally. We are all wrong when we say there is no vital difference between the sexes. There is every difference. Every bit, every cell in a boy is male, every cell is female in a woman, and must remain so. Women can never feel or know as men do. And in the reverse men can never feel and know, dynamically, as women do. Man, acting in the passive or feminine polarity, is still man, and he doesn't have one single unmanly feeling. And women, when they speak and write, utter not one single word that men have not taught them. Men learn their feelings from women, women learn their mental consciousness from men. And so it will ever be. Meanwhile, women live forever by feeling, and men live forever from an inherent sense of _purpose_. Feeling is an end in itself. This is unspeakable truth to a woman, and never true for one minute to a man. When man, in the Epicurean spirit, embraces feeling, he makes himself a martyr to it--like Maupassant or Oscar Wilde. Woman will _never_ understand the depth of the spirit of purpose in man, his deeper spirit. And man will never understand the sacredness of feeling to woman. Each will play at the other's game, but they will remain apart. The whole mode, the whole everything is really different in man and woman. Therefore we should keep boys and girls apart, that they are pure and virgin in themselves. On mixing with one another, in becoming familiar, in being "pals," they lose their own male and female integrity. And they lose the treasure of the future, the vital sex polarity, the dynamic magic of life. For the magic and the dynamism rests on _otherness_. For actual sex is a vital polarity. And a polarity which rouses into action, as we know, at puberty. And how? As we know, a child lives from the great field of dynamic consciousness established between the four poles of the dynamic psyche, two great poles of sympathy, two great poles of will. The solar plexus and the lumbar ganglion, great nerve-centers below the diaphragm, act as the dynamic origin of all consciousness in man, and are immediately polarized by the other two nerve-centers, the cardiac plexus and the thoracic ganglion above the diaphragm. At these four poles the whole flow, both within the individual and from without him, of dynamic consciousness and dynamic creative relationship is centered. These four first poles constitute the first field of dynamic consciousness for the first twelve or fourteen years of the life of every child. And then a change takes place. It takes place slowly, gradually and inevitably, utterly beyond our provision or control. The living soul is unfolding itself in another great metamorphosis.
