According to Thoreau in Walden, the most beneficial education is achieved by what?

As an American Romantic, Thoreau clearly did not believe
in the benefits of civilisation and living with others. This text is his account of his
own sojourn to be with nature, which he saw as the perfect kind of education that
anybody could wish for. Let us consider his reasons for secluding himself away from
human company and how this relates to his ideas about education. If we look at "Where I
Lived, and What I Lived For," Thoreau very clearly states his reasons for doing what he
did:

I went
to the woods because I wished to live deliberately, to front only the essential facts of
life, and see if I could not learn what it had to teach, and not, when I came to die,
discover that I had not
lived.

Secluding yourself
from civilisation therefore enables one to "live deliberately" and to learn the
important lessons that are available to us from nature if we have ears to hear them. In
addition, not the way that this quote infers that to be blind and deaf to these lessons
from nature is to spend your life not really living. Therefore we can conclude that
Thoreau would have said the most beneficial education would be achieved by doing what he
did and secluding yourself away from humanity and spending time alone in
nature.
