After World War II, writers attempted to come to terms with where humanity was going after the belief in many of the things that were held as fundamental had been shattered. Disillusioned, many modernists placed their focus upon individualism, employing a new technique called "stream of consciousness" narration with the theme of the randomness of life. Moreover, the Modernist movement was concerned with the quickening of society towards its destruction and lack of meaning. Certainly, several of the elements of Modernism are present in F. Scott Fitzgerald's "Babylon Revisited."
Randomness of life
As expatriates in Paris, Charlie Wales lives a rather hedonistic and impetuous life. However, with the crash of 1929, things change drastically for him. Years later, Charlie does recover financially, but his personal life is an absolute wreck because of his alcoholism The fateful night on which his wife walks in the cold rain is certainly a random act, but one with tragic results.
Society's movement towards its own destruction meaninglessness
Charlie Wales rationalizes his drinking problem and dismisses important issues--"The depression of yesterday was gone."
The former friends of Charlie, Duncan Scaeffer and Lorraine Quarrles seek to "draw a certain sustenance from his strength," but they really destroy Charlie's chances of regaining custody of his daughter Honoria. Hedonistic, they are only concerned with Charlie's joining them for drinks and partying.
Constantly Marion, his sister-in-law is the voice of practicality. As a foil to Charlie's irresponsibility she often asks such questions as "Why didn't you think of all this before?"
Stream-of-consciousness narration and allusiveness,
In several passages in the story, Charlie's thoughts are intermixed with the third-person narration, providing the Modernist stream-of-consciousness, interior monologue. Here are examples:
He had never eaten at a really cheap restaurant in Paris. Five-course dinner, four francs fifty, eighteen cents, wine included. For some odd reason he wished that he had
He believed in character; he wanted to jump back a whole generation and trust in character again as the eternally valuable element. Everything else wore out
He would come back some day; they couldn't make him pay forever. But he wanted his child, and nothing was much good now, beside that fact.... He was absolutely sure Helen wouldn't have wanted him to be so alone.
In his effort to escape the past, Charlie tries to avoid Duncan and Lorraine. But he fails, just as he fails to convince Marion that he has changed because he lets his friends and his alcoholism control him. Finally, at the end, Charlie engages again in interior monologue in which he vows to "come back someday" because
...he wanted his child, and nothing was much good now, beside that fact.
Perhaps futilely, Charlie ultimately understands that he must create his own destiny. And, so, he promises not to revisit Babylon the next time.
