We need the tonic of wildness...At the same time that we are earnest to explore and learn all things, we require that all things be mysterious and unexplorable, that land and sea be indefinitely wild, unsurveyed and unfathomed by us because unfathomable. We can never have enough of nature.

Wildness is the preservation of the World.

It is in vain to dream of a wildness distant from ourselves. There is none such. It is in the bog in our brains and bowels, the primitive vigour of Nature in us, that inspires that dream. I shall never find in the wilds of Labrador any greater wildness than in some recess of Concord, i.e. than I import into it.

...is not Nature, rightly read, that of which she is commonly taken to be the symbol merely?

The most primitive places left with us are the swamps, where the spruce still grows shaggy with usnea.
