This paper explores the technological diegesis in "The Great Gatsby." In the novel, Fitzgerald cleverly integrates the technological forces into his writing. He particularly relies on the two main props of automobile and telephone to arrange his fragmented plots into a whole. By the deliberate juxtaposition of men and women and machines and repeated appeal to the automobile as both carrier and destroyer and the telephone as both communicator and informer, the technological diegesis in the novel is fully established. Moreover, the technological forces in this particular novel are metaphorically constructed into the whole discourse of it.
