Gertrude Stein
coined the phrase "The Lost Generation" and Hemingway portrays characters who are very
much apart of this group. The lost generation felt disillusioned post WWI, and many fled to
Europe to escape the facade of the american dream. Yet, they led very superficial lives.
Drinking, travelling, forming no real attachments, this group believes they have left behind the
hypocrisy of America, but still represent America whereever they go.
