Perhaps you're thinking of one of his iconic novels like "The Great Gatsby," which is considered a quintessential example of Modernist literature.
Here's what Modernism is about in a nutshell, and how it might be reflected in Fitzgerald's works:
* A break from traditional norms: Modernist writers challenged the old ways of writing and thinking, reflecting the rapid changes in society after World War I.
* Focus on individual experience: Instead of grand narratives, Modernists explored the inner lives and fragmented experiences of individuals.
* Exploration of alienation and disillusionment: Modernist writers often tackled themes of loss, loneliness, and the breakdown of social structures.
* Stream of consciousness: This writing style mimics the flow of thoughts, allowing for a more direct and intimate portrayal of characters.
* Emphasis on symbolism and ambiguity: Meaning was often left open to interpretation, reflecting the uncertainty of the modern world.
In Fitzgerald's works, we see these elements:
* The Great Gatsby: The American Dream's disillusionment, Gatsby's pursuit of lost love, and the social divide between the old and new money.
* Tender Is the Night: Themes of love, disillusionment, and the decay of the American Dream are intertwined with psychological complexity and the fragmented nature of the characters' experiences.
