Thoreau distinguishes the natural world in contrast to the human world by emphasizing a sense of belonging and connection he feels with nature. He describes his experiences in nature with phrases like "strange liberty" and "a part of herself," indicating a deep bond and comfort he finds in the natural environment. While humans are often portrayed as seeking social connections, Thoreau suggests that true fulfillment comes from nature itself, where he finds solace and congeniality, regardless of external conditions like coolness or windiness. Therefore, the response that best captures Thoreau's perspective is:
Nature is where he feels like he belongs.
