Lord of the Flies (for Seniors)

What about their subservience to authority, even on a deserted island? There are several references to authority in chapter four:

• The little ones listen to Ralph because "he was big enough to be a link with the adult world of authority..."
• Maurice kicked sand in Percival's eyes and immediately felt bad about it. "In his other life, Maurice had received chastisement for filling a younger eye with sand. Now, though there was no parent to let fall a heavy hand, Maurice still fel the unease of wrongdoing."
• Roger threw stones towards Henry, but deliberately didn't try to hit him. "Round the squatting child was the protection of parents and school and policemen and the law. Roger's arm was conditioned by a civilization that knew nothing of him and was in ruins."

Why are the boys still obedient? Why are they looking for someone to listen to? Even though we often wish we could defy authority, if it wasn't there, would we continue to do things the ways that we know are right?
