Answer:
Metaphors:
"I left the woods for as good a reason as I went there. Perhaps it seemed to me that I had several more lives to live, and could not spare any more time for that one." (referring to his decision to leave Walden Pond)
"I learned this, at least, by my experiment: that if one advances confidently in the direction of his dreams, and endeavors to live the life which he has imagined, he will meet with a success unexpected in common hours." (referring to his philosophy on pursuing one's dreams)
Ways in which they refine the meaning of the text and allow for generalizations about Thoreau's beliefs:
The metaphor of leaving the woods for a new life suggests that Thoreau believes in the importance of change and growth, and that staying in one place for too long can limit one's potential experiences and opportunities.
The metaphor of advancing confidently in the direction of one's dreams suggests that Thoreau believes in the power of determination and self-belief, and that pursuing one's passions can lead to unexpected success. It also implies that taking risks and stepping out of one's comfort zone can be beneficial.
Overall, Thoreau's use of metaphors in the conclusion of Walden reinforces his belief in the importance of personal growth and pursuing one's dreams, even if it means leaving behind familiar comforts and taking risks.
