The tension between individual desire and societal expectations is a recurring theme throughout the novel. Newland's engagement to May Welland represents the socially acceptable choice, while his attraction to Ellen Olenska symbolizes the forbidden and the unknown. Wharton expertly portrays the inner turmoil that Newland experiences as he grapples with these conflicting desires. Ultimately, Newland's decision to conform to societal expectations, by marrying May and abandoning his chance with Ellen, underscores the powerful influence of social norms on individual behavior.
