The document discusses symbolism in literature and identifies several symbols in S.E. Hinton's novel The Outsiders. It explains that symbols represent something on both a literal and symbolic level. Some of the key symbols in The Outsiders are the switchblade representing strength for Greasers, the blue Mustang representing wealth and power for Socs, cigarettes representing fitting in for Greasers, the drive-in movie theater as a place where Greasers and Socs could coexist, Soda's horse Mickey Mouse connecting the boys to innocence, and the church providing refuge but also revealing the characters' true selves. The document suggests Hinton deliberately used these symbols to serve some purpose in the novel.
