Quote from Lord of the Flies Page 111

''Ralph-we need meat even if we are hunting the other thing.'"
-Lord of the Flies Page 111
Even as the group is trying to hunt the beast, many of the boys can only thing of hunting, killing, and eating pigs. The thought of meat seems to put the boys in a trance where the sole objects in their minds is killing pigs. This obsession with meat is beginning to tear the island apart. Even Ralph's mind is beginning to embrace the ideas of hunting pigs. This obsession may eventually lead to the demise of the order on the island.

The divisions in the island become even deeper. Jack's group of boys continues to become more and more savage. They seem to be regressing to a primal human state. It is almost as if the boys are devolving mentally into simple hunters and gatherers. Ralph, Piggy, and the twins are the only ones on the island who seem to keep their wits about them in the face of the island. Simon, along with Jack and the savages, also seems to be losing his sanity. His thoughtfulness earlier in the story seems to be leeching out of his personality. His delusion of the talking pig may be a symbol of how man is his own worst enemy and biggest threat to himself. Simon's theory that man is the biggest threat is shown in Jack's hostile actions towards those who did not join his group. He acts as if he may attempt to kill them off soon.
