Piggy says, "Grown-ups know things; the majesty of adult life". Is Piggy right? Are the boys failing only because they aren't grown-ups?
Piggy represents the intellectual in the group. He is the quiet thinker. He realizes that they must be smart in order to survive and in order to get rescued. He compares the boys' efforts and antics to grown-ups more than once in the book. When Ralph expresses frustration at the deteriorating society of boys, Piggy tells them they must persevere because that is what grown-ups would do. Not long before he's killed, he reminds the few remaining boys on Ralph's side that they really aren't savages; that they all come from a civilized society and they need to remember that and get back to that. He asks what would the grown-ups think of them and how they've let things deteriorate. Piggy believes that grown-ups are more mature. He believes that they would not devolve into an uncivilized pack of savages. He looks upon adults as the ones who know the answer because he is still, after all, only a child. He hasn't become cynical about adults yet. The irony, of course, is that it was the adults in the world who ultimately caused the boys to be in the situation in which they are in because the adults couldn't get along. The world the boys left is really no more civilized than the one they have created on the island.
