Mark Twain uses Huck Finn as the narrator in "The Adventures of Huckleberry Finn" for several reasons. Firstly, Huck Finn's narrative perspective provides a unique and authentic voice for the story. Twain wanted to capture the language and mindset of a young, uneducated boy living in the American South during the mid-19th century. Through Huck's perspective, Twain effectively conveys the vernacular speech, regional dialects, and social attitudes of the time.
Secondly, Huck's character allows Twain to explore important themes and social commentary. As an outsider and a rebel against societal norms, Huck provides a critical lens through which Twain can satirize and critique the hypocrisies and injustices of society. Huck's moral conflicts and growth throughout the story also serve as a vehicle for Twain to address complex issues such as racism, slavery, and the nature of freedom.
Additionally, Huck's youthful innocence and curiosity create a sense of adventure and allow readers to experience the story through the eyes of a young protagonist. Huck's observations and encounters with various characters, such as Jim, Tom Sawyer, and the Duke and Dauphin, contribute to the novel's humor, satire, and exploration of human nature.
Overall, by using Huck Finn as the narrator, Mark Twain achieves a distinctive narrative voice, engages in social critique, explores significant themes, and provides readers with an immersive and entertaining perspective on the events and people of the time.
