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.
