The central theme of this book centers on George Willard's journey to maturity, culminating in his ultimate departure from the town. Unlike novels driven by external events, this story lacks a defining incident that propels him to leave. George appears to be the ideal resident of Winesburg; just as the townspeople rely on him to share their stories, he equally depends on them to satisfy his curiosity.

George's development beyond the town is subtly portrayed through readers' responses to each character. For instance, "Hands" may focus on Wing's attempt to escape his past, but it also underscores the narrow-mindedness and anger that can arise in a small town. In "Nobody Knows," George's main concern following a sexual encounter is ensuring that no one finds out. The bullies in "A Man of Ideas" tolerate Joe Welling because he remains oblivious to the dangers in Winesburg. Although "The Untold Lie" doesn't mention George, it still makes readers aware that the hardships Ray Pearson faces are inevitable in a place like Winesburg.

As the town increasingly feels like a trap for someone like George, leaving becomes a viable option during a pivotal moment in "Sophistication." Here, George reverses his maturation process and, instead of trying to act older, breaks away from a kiss with Helen White. They both laugh, transforming into "not man and woman, not boy and girl, but excited little animals." The desire for experience and understanding fades as they run down the hill, "playing like two splendid young things in a young world." The internal conflict with "the young thing within" that has challenged George in every story, through his interactions with disillusioned older Winesburg residents, is resolved, signaling his time to leave.

The main source of dramatic tension in this book arises from Winesburg's nature as a small town. The residents are closely acquainted and expect each other to adhere to certain behavioral norms. Despite this familiarity, they all feel a sense of alienation. Among them, Elizabeth Willard, the mother of the novel's central figure, is particularly isolated. The story "Mother" reveals that in her youth, she felt a connection with the traveling men who visited the Willard house and courted her. The narrative notes, "They seemed to understand and sympathize with her." Yet, in her later years, she lacks such connections, even with her husband or son, and secludes herself upstairs to avoid being seen.

In the closing years of her life, as depicted in "Death," her solitude is momentarily broken through her bond with Dr. Reefy, whom she meets in his secluded office next to a dusty storage room. Their relationship reaches a peak and then dissolves when they embrace for the first time and are interrupted by a clerk discarding a box in the hallway: "Doctor Reefy did not see the woman he had held in his arms again until after her death." Elizabeth Willard is so isolated that she never gets to disclose the secret she had kept for her son—eight hundred dollars in cash, hidden inside a wall.

Another vivid example of the widespread loneliness affecting the characters in this book is Enoch Robinson, featured in the story "Loneliness." Interestingly, the narrative explains that it was in New York City where Robinson withdrew from reality to live among imaginary people, only to lose them to a girl he was involved with. While Robinson feels lonely in Winesburg, the town itself isn't the cause, implying that the alienation experienced by Winesburg's residents is more a universal human condition than a result of small-town life.
