what quote is there that i can use in my assignment about the loss of individuality?

You can consider this one,

"Sleep teaching was actually prohibited in England. There was something called liberalism. Parliament, if you know what that was, passed a law against it. The records survive. Speeches about liberty of the subject. Liberty to be inefficient and miserable. Freedom to be a round peg in a square hole." (3.138)

Mustapha describes this liberalist sentiment with ridicule – why would anyone want to be inefficient and miserable? But this is exactly the freedom John will later claim – the freedom to be unhappy.
