What does the Jungle symbolize in "Lord Of The Flies"?

The entire story is a allegory. In other words, the story represents abstract ideas through, in this case, characters and setting. Golding wants the reader to consider whether or not humans are born evil and are civil only because the consequences and restrictions of law and religion. Therefore, the jungle -- a place completely exempt of societal order -- is an ideal setting to analyze human behavior in its most natural state.
