Which English Literature novels go well with the theory of materialism for my proposal thesis?
The mention of English literature and "the theory of materialism" call to mind the early novels of E.M. Forester. His novel, Howard's End, concerns itself with Edwardian society and class conflicts within this society. In this novel, there are two families about which Forester writes: the Schlegel family and the Wilcox family. The Schlegels represent intellectualism, and idealism while the Wilcoxes represent expansionism, commercialism, practicality, and materialism. It is through the marriage of Margaret and Henry Wilcox that these differing worlds are united; and, it is through this uniting of differing beliefs that conflict comes into play.
Just to clarify, are you asking for an example of a novel that deals with the theme of materialism? I think Fitzgerald's The Great Gatsby is a novel in which this theme is very apparent. Most of the characters in the novel are wealthy, and the main character, Jay Gatsby, worked hard to achieve his wealth and status. He throws lavish parties and lives a decadent life, attempting to find fulfillment; however, the novel ultimately rails against the notion that material goods alone can give people fulfillment or "buy happiness."
