"Soon the child’s clear eye is clouded over by ideas and opinions, preconceptions, and abstractions. Simple free being becomes encrusted with the burdensome armor of the ego. Not until years later does an instinct come that a vital sense of mystery has been withdrawn. The sun glints through the pines and the heart is pierced in a moment of beauty and strange pain, like a memory of paradise. After that day, we become seekers."

""There's an elegiac quality in watching [American wilderness:] go, because it's our own myth, the American frontier, that's deteriorating before our eyes. I feel a deep sorrow that my kids will never get to see what I've seen, and their kids will see nothing; there's a deep sadness whenever I look at nature now.""
