Explanation:
According to the context of your question, we can assume that you are referring to the text "Walden," where Thoreau tells about the experience of living near Lake Walden, where he was completely isolated from civilization and had several reflections on being human, life and society. After two years, he decided to leave this region, saying that he needed to live new experiences. He justified his departure, stating that human beings need to abandon their luxuries and pleasures, such as luxurious clothes and comfortable homes, in order to be able to recognize their true self and connect to their own thoughts.
