Walden gives us a glimpse into the life and thoughts of Henry Thoreau, in which, he describes his meaningful time at Walden Pond.
However, there is some speculation on where the purpose of existence can be found in the book.
Thoreau meant for the readers to open their minds. If we take our time to be aware and enjoy the small details within life, our lives will be more enriching.
For example, in The Machine in the Garden: Technology and the Pastoral Ideal in America, Leo Marx writes Thoreau
is clear…about the location of [ultimate] meaning and value”: “He is saying that it does not reside in the natural facts or in social institutions or in anything ‘out there,’ but in consciousness. It is the product of imaginative perception, of the analogy-perceiving, metaphor-making, mythopoeic power of the human mind.1
