| Quote #1 "Reducing the number of revolutions per minute," Mr. Foster explained. "The surrogate goes round slower; therefore passes through the lung at longer intervals; therefore gives the embryo less oxygen. Nothing like oxygen-shortage for keeping an embryo below par." Again he rubbed his hands. |
Mr. Foster's calculating enthusiasm (rubbing his hands in excitement) is concentrated here with the horror of the caste system – horrible not only for its restrictive, predetermining qualities, but also for the destructive, malevolent, harmful way in which its ends are achieved.
| Quote #2 They hurried out of the room and returned in a minute or two, each pushing a kind of tall dumb-waiter laden, on all its four wire-netted shelves, with eight-month-old babies, all exactly alike (a Bokanovsky Group, it was evident) and all (since their caste was Delta) dressed in khaki. (2.8) |
That castes are distinguished by their clothing further dehumanizes them. To any member of a higher caste, ALL Deltas will look exactly the same.
| Quote #3 "… all wear green," said a soft but very distinct voice, beginning in the middle of a sentence, "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 colour. I'm so glad I'm a Beta." |
It's likely that the castes are kept separate for the sake of stability; this way there is no envy and no complications from intermingling. Each individual can view members of a different caste as a faceless, nameless 'other.'
