In wilderness is the preservation of the world.

You were once wild here

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

Wildness is the preservation of the World.

Generally speaking, a howling wilderness does not howl: it is the imagination of the traveler that does the howling.

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.
