Often times, authors use characters in their novels and stories as symbols. The characters may be symbolic of the tangible as well as the non-tangible. In addition, characters can often be looked at with a psychological approach to literature in order to better determine or understand their symbolic significance. In William Golding's Lord of the Flies, special symbolic significance may be found in the characters, Piggy, Ralph, and Jack.

             By now they were listening to the tirade.
             "How can you expect to be rescued if you don't put first things first and act proper?"
             He took off his glasses and made as if to put down the conch; but the sudden motion towards it of most of the older boys changed his mind. He tucked the shell under his arm, and crouched back on a rock.
             "Then when you get here you build a bonfire that isn't no use. Now you been and set the whole island on fire. Won't we look fun...
