What does Walden symbolize in Thoreau’s work?

In Thoreau's work, Walden symbolizes a quest for simplicity. Thoreau’s experiment in living at Walden Pond was not just about solitude or a rejection of society; it was a purposeful search for a simpler, more intentional life. He sought to strip away the complexities and distractions of modern civilization in order to connect more deeply with nature and with himself. Through his writings, Thoreau illustrates how embracing simplicity can lead to greater clarity and purpose, highlighting the importance of self-reliance and mindfulness in one's existence.

In contrast, the other options reflect aspects of his work but do not encapsulate the central theme of Walden as effectively. Thoreau's exploration is not primarily concerned with urban life—he actively distances himself from it. While he does address individual struggles, they serve more as a backdrop to the overarching journey towards simplicity. Similarly, although nature plays a significant role in his reflections, it is ultimately the pursuit of simplicity within that natural context that serves as the foundation of his philosophy.
