A man could be a lover and defender of the wilderness without ever in his lifetime leaving the boundaries of asphalt, power lines, and right-angled surfaces. We need wilderness whether or not we ever set foot in it. We need a refuge even though we may never need to go there. I may never in my life go to Alaska, for example, but I am grateful that it is there. We need the possibility of escape as surely as we need hope; without it the life of the cities would drive all men into crime or drugs or psychoanalysis.
