In the "Conclusion" of Walden, Henry David Thoreau uses a number of metaphors to refine the meaning of the text and allow readers to make generalizations about his beliefs. For example, Thoreau compares life to a journey, writing that "We should go forth on the shortest walk, perchance, in the spirit of undying adventure, never to return" (Thoreau). This metaphor suggests that life is a constant journey, and that we should approach it with a sense of wonder and curiosity.
Thoreau also uses the metaphor of a battle to describe the struggle to live a meaningful life. He writes, "The battle which was occasionally necessary to get rid of him, the contest between the two principles, ... were invariably decided in favor of the former" (Thoreau). This metaphor suggests that the pursuit of a meaningful life is a struggle against the forces of conformity and complacency, and that we must be willing to fight for our beliefs and principles.
Finally, Thoreau uses the metaphor of a seed to describe the potential for growth and change within each individual. He writes, "We need to be reminded that we are but newly born beings, struggling from childishness toward maturity; and need to be treated accordingly" (Thoreau). This metaphor suggests that we all have the potential to grow and change, but that we must be nurtured and given the space to do so.
Through these metaphors, Thoreau refines the meaning of Walden, suggesting that life is a constant journey that requires us to fight for our beliefs and nurture our potential for growth and change. Thoreau's use of metaphor also allows readers to make generalizations about his beliefs, including his emphasis on individualism, self-reliance, and the importance of living a meaningful life in harmony with nature.
