Symbolic Of What?

In Lord Of The Flies there is tons upon tons of symbolism, which is why it is referred to as an allegory. It is nearly impossible for one person to identify every layer of every word. Literally, every word is planned and thought out. Which is what allegory is supposed to be. The book overall, I interpret, is a symbol of human nature and modern politics. Piggy, The fat, spectacled boy with a serious case of "ass-mar" is representative of intelligence and people who occasionally put well educated input into politics but never assume a leadership role. Ralph, in my opinion, is like George Washington in a way, everyone assumed him as leader, and he sets some precedents (the conch, daily meetings, rules). Finally, Jack is symbolic of the evil that lies within humans, that forces them to want to kill, to hurt, which is exemplified in the scene where they play the pig game with robert.
