How does Buck's perspective on survival differ from the humans he encounters?

Buck's perspective on survival fundamentally emphasizes the importance of instincts and natural law, which aligns with the themes of nature versus nurture and the underlying principles of survival in the wild. As Buck adapts to his new environment, he learns to trust his instincts and rely on the natural order of things to navigate challenges. This instinctual approach starkly contrasts with the humans he encounters, who often depend on technology, social constructs, and their own societal rules rather than the more primal elements of survival.

Buck's understanding grows as he experiences the harsh realities of life in the wild, highlighting the significance of instinct, adaptability, and the intrinsic laws of nature. This evolution in his character underscores the novel's exploration of the animalistic qualities that emerge when survival is at stake. Therefore, valuing instincts and natural law over the artificial constructs of human civilization captures the essence of Buck's transformation and the core message of the story regarding the relationship between humans and nature.
