You have got to base your great purposive activity upon the intense sexual fulfillment of all your individuals.

That was how Egypt endured.

But you have got to keep your sexual fulfillment even then subordinate, just subordinate to the great passion of purpose: subordinate by a hair's breadth only: but still, by that hair's breadth, subordinate.
Perhaps we can see now a little better--to go back to the child--where Freud is wrong in attributing a sexual motive to all human activity.
It is obvious there is no real sexual motive in a child, for example.
The great sexual centers are not even awake.

True, even in a child of three, rudimentary sex throws strange shadows on the wall, in its approach from the distance.

But these are only an uneasy intrusion from the as-yet-uncreated, unready biological centers.
