what is a quote that backs up how piggeys glasses give him purpose and what page is it found on?

Piggy needs his glasses to see. When Jack finally steals his glasses Piggy is physically disabled more than he ever was before,

“That’s them,” said Piggy. “They blinded me. See? That’s Jack Mer-

ridew.

Piggy strives for some semblance of fairness. In chapter 11 a blind Piggy courageously says he will tell Jack,

You can see, I’m goin’ to say, and with both eyes. But I don’t ask for my glasses back, not as a favor. I don’t ask you to be a sport, I’ll say, not because you’re strong, but because what’s right’s right. Give me my

glasses, I’m going to say—you got to!”

What is piggy presupposing about the situation and the significance of morality?
