What does the wilderness symbolize in Buck's journey?

The wilderness serves as a powerful symbol in Buck's journey, representing freedom and the reawakening of his primal instincts. Throughout the story, Buck transitions from a domesticated pet to a creature that embraces his ancestral heritage. As he navigates the wild environment, he sheds the constraints of civilization and begins to connect with his inner being, responding to natural instincts that had been dormant during his life in a human home.

This transformation illustrates not only Buck's physical survival but also his emotional and psychological liberation. The wilderness becomes a place where he can truly thrive and realize his full potential as a wolf, untethered from the roles imposed on him by humans. Ultimately, Buck's journey reflects the idea that nature can offer a profound sense of freedom and authenticity, allowing him to reclaim his identity in a way that civilized life never could.
