The wilderness that has come to us out of the eternity of the past, we have the boldness to project into the eternity of the future.

I believe we have a profound fundamental need for areas of the earth where we stand without our mechanisms that make us immediate masters over our environment.

By very definition this wilderness is a need. The idea of wilderness as an area without man's influence is man's own concept. Its values are human values. Its preservation is a purpose that arises out of man's own sense of his fundamental needs

We deeply need the humility to know ourselves as the dependent members of a great community of life, and this can indeed be one of the spiritual benefits of a wilderness experience. ... [T]o know the wilderness is to know a profound humility, to recognize one's littleness, to sense dependence and interdependence, indebtedness and responsibility.
