Final answer:
Huck is relieved to discover his identity because it allows him a sense of security and place within the social order. Mark Twain's Huckleberry Finn emphasizes this theme through Huck's interactions with nature and his quest for personal freedom, paralleling the journey of self-discovery found in other literary works.
Step-by-step explanation:
Huck is relieved to find out who he is supposed to be because it affirms his sense of identity and his role in the social world. Mark Twain's works, including the adventures of Huckleberry Finn, often explore themes of identity and personal freedom.
Huck's relief at understanding his identity aligns with themes echoed by other authors, such as Ralph Ellison's statement, "When I discover who I am, I'll be free." This moment of self-realization signifies a departure from the "idleness" and the confusion of not knowing one's place in the world, which can be paralleled with the character's growth and the appeal of the natural environment as a backdrop for self-discovery.
Moreover, Twain uses Huck's experiences, such as his life on the raft and his observations of nature, to interrogate the idea of freedom and the quest to find one's place in society.
Huck is relieved to find out who he is supposed to be because it provides him with a sense of identity and purpose. Throughout the novel, Huck struggles with his identity as he defies societal norms and expectations. Discovering his true identity, even if it means going against the norms, brings him a sense of relief and allows him to move forward with a clearer sense of self.
