"We need wilderness because we are wild animals. Every man needs a place where he can go to go crazy in peace. Every Boy Scout deserves a forest to get lost, miserable, and starving in. Even the maddest murderer of the sweetest wife should get a chance for a run to the sanctuary of the hills. If only for the sport of it. For the terror, freedom, and delirium. Because we need brutality and raw adventure, because men and women first learned to love in, under, and all around trees, because we need for every pair of feet and legs about ten leagues of naked nature, crags to leap from, mountains to measure by, deserts to finally die in when the heart fails."
