"Think of water under pressure in a pipe." They thought of it. "I pierce it once," said the Controller. "What a jet!"
He pierced it twenty times. There were twenty piddling little fountains.

Mother, monogamy, romance. High spurts the fountain; fierce and foamy the wild jet. The urge has but a single outlet. My love, my baby. No wonder these poor pre-moderns were mad and wicked and miserable. Their world didn't allow them to take things easily, didn't allow them to be sane, virtuous, happy. What with mothers and lovers, what with the prohibitions they were not conditioned to obey, what with the temptations and the lonely remorses, what with all the diseases and the endless isolating pain, what with the uncertainties and the poverty—they were forced to feel strongly. And feeling strongly (and strongly, what was more, in solitude, in hopelessly individual isolation), how could they be stable? (3.94-9)
Here begins the connection between mother-child love and sexual love. In the eyes of Mustapha, both are condemnable because they lead to emotions, which lead to instability. But this Freudian stuff will have much larger implications in the novel, especially when it comes to John and Linda. Stay tuned. (And admire how sneakily Huxley got us thinking in that direction right off the bat.)
Quote 8
"[…] chastity means passion, chastity means neurasthenia. And passion and neurasthenia mean instability. And instability means the end of civilization. You can't have a lasting civilization without plenty of pleasant vices." (17.45)
Mustapha claims that promiscuity is necessary to avoid feelings of unfulfilled desire. John will later establish that such feelings are part of being a human. It follows, then, that in creating "lasting civilization," the World Controllers have destroyed humanity. If this is true, what they're running isn't exactly a "civilization" at all.
Quote 9
"Stability," said the Controller, "stability. No civilization without social stability. No social stability without individual stability." His voice was a trumpet. Listening they felt larger, warmer. (3.105)
Mustapha's voice becomes an important part of his character, both here and later in Chapter 17 when he has his philosophical discussion with John. Check out his "Character Analysis" for more info and to read about our suggestion that words = control in Brave New World.
