“Pilkington, at Mombasa, had produced individuals who were sexually mature at four and full grown at six and a half. A scientific triumph. But socially useless. Six-year-old men and women were too stupid to do even Epsilon work. And the process was an all-or-nothing one; either you failed to modify at all, or else you modified the whole way. They were still trying to find the ideal compromise between adults of twenty and adults of six. So far without success. Mr Foster sighed and shook his head.”

“Alpha children wear grey. They work much harder than we do, because they're so frightfully clever. I'm awfully glad I'm a Beta, because I don't work so hard. And then we are much better than the Gammas and Deltas. Gammas are stupid. They all wear green, and Delta children wear khaki. Oh no, I don't want to play with Delta children. And Epsilons are still worse. They're too stupid to be able to read or write. Besides they wear black, which is such a beastly color. I'm so glad I'm a Beta.”

“He rubbed his hands. For, of course, they didn't content themselves with merely hatching out embryos: any cow could do that. "We also predestine and condition. We decant our babies as socialized human beings, as Alphas or Epsilons, as future sewage workers or future..." He was going to say "future World Controllers", but correcting himself, said "future Directors of Hatcheries" instead.”

“And if you were an Epsilon,' said Henry, 'your conditioning would have made you no less thankful that you weren't a Beta or an Alpha.”

“To travel is to discover that everyone is wrong about other countries.”

“Anyone without a sense of humor is at the mercy of everyone else.”
