American Expansionism
relates to Thoreau
Roderick Nash writes: "Thoreau left Concord in 1846 for the first of three trips to northern Maine. His expectations were high because he hoped to find genuine, primeval America. But contact with real wilderness in Maine affected him far differently than had the idea of wilderness in Concord. Instead of coming out of the woods with a deepened appreciation of the wilds, Thoreau felt a greater respect for civilization and realized the necessity of
balance.
He wrote in Walden: "The practical objection to animal food in my case was its uncleanness; and besides, when I had caught and cleaned and cooked and eaten my fish, they seemed not to have fed me essentially. It was insignificant and unnecessary, and cost more than it came to. A little bread or a few potatoes would have done as well, with less trouble and filth."
