When Bernard is told he is being sent to an island, he completely loses control of himself. He gets so hysterical that he has to be subdued by guards. They carry him away (they are told to go and spray him with soma so he'll calm down and then let him rest).
Mond then tells Helmholtz and John about a bit of history. He says it was mass production of goods that made people stop thinking about truth and beauty and start thinking instead about comfort and happiness. He says, in other words, that once there came to be lots of stuff available, people cared only about material goods and not about thinking.
