The couch, Piggy’s glasses and the fire are all examples of symbols that change meaning in the novel Lord of then Flies, by William Golding. In the beginning of the book the conch represents power and government on the island, but in the end ends up representing the fall. Much like Piggy’s glasses represented technogical advances and then, ten loss of humanity in the boys. The fire represented hope for survival, but was later used for death. These symbols show how in a book, anything can change and become the opposite of what it was first meant for.
