“Wilderness is not a luxury but a necessity of the human spirit, and as vital to our lives as water and good bread. A civilization which destroys what little remains of the wild, the spare, the original, is cutting itself off from its origins and betraying the principle of civilization itself.”

“The automobile, which began as a transportation convenience, has become a bloody tyrant (50,000 lives a year), and it is the responsibility of the park service, as well as that of everyone else concerned with preserving both wilderness and civilization, to begin a campaign of resistance.”

“Wilderness. The word itself is music.”

“i was accused of being against civilization, against science, against humanity. naturally, i was flattered and at the same time surprised, hurt, a little shocked. he repeated the charge. but how, i replied, being myself a member of humanity (albeit involuntarily, without prior consultation), could i be against humanity without being against myself, whom i love - though not very much; how can i be against science, when i gratefully admire, as much as i can, thales, democritus, aristarchus, faustus, paracelsus, copernicus, galiley, kepler, newton, darwin and einstien; and finally, how could i be against civilization when all which i most willingly defend and venerate - including the love of wilderness - is comprehended by the term”

“It is vital that we avoid any hint of moral superiority in our dealings with one another in the environmental movement; if it developed into factionalism it would destroy us, as factionalism has destroyed so many other progressive movements in America.”
