O brave new ironic world!

"'O brave new world,' he repeated. 'O brave new world that has such people in it. Let's start at once.'" - pg 139

Finally, the origin of the novel's title is revealed. Ironically, it was Shakespeare who lent his voice to the title. This is an odd choice since only one character knows about or is familiar with Shakespeare. John, the most unique and self-determined character in the book, speaks the title aloud when he is invited to visit the modern world with Bernard. This later becomes a habit of John's that sets him at odds with the people in the modern world. Although John did not intend this to be true, since he had never seen the "brave new world", but his words could not be farther from the truth.

Get it? I 

The world of the novel is the complete opposite of brave. The controllers are so afraid of economic collapse, disorder, individuality, family life, and monogamy that have insulated themselves and society from every surprise, fear, and unpredictability. They have protected themselves from the possibility of problems and mishaps. They have sacrificed true human life and passion in order to never have to deal with the side effects of regular human life. This sacrifice is the opposite of brave.

Also, the use of the word 'new' could not be more false. The world in the physical sense or in the sense of time is not new, it is archaic. While the lifestyle of the characters may be new and different from the old, but it is not at all new, but merely a different organization of the same world as before. John may soon decide to retract his statement.
