The survival of wilderness -- of places that we do not change, where we allow the existence of creatures we perceive as dangerous -- is necessary. Our sanity probably requires it. These places function, whether we intend them to or not, as sacred groves -- places we respect and leave alone, not because we understand well what goes on there, but because we do not.
Joy and woe are woven fine,
A clothing for the soul divine,
Under every grief and pine,
Runs a joy with silken twine.
It is right it should be so,
We were made for joy and woe,
And when this we rightly know,
Through the world we safely go.
