“Limitation of scope, however, could represent a profound advantage from an ecological point of view. The sun, the wind and the earth are experiential realities to which men have responded sensuously and reverently from time immemorial. Out of these primal elements man developed his sense of dependence on—and respect for—the natural environment, a dependence that kept his destructive activities in check. The Industrial Revolution and the urbanized world that followed obscured nature's role in human experience—hiding the sun with a pall of smoke, blocking the winds with massive buildings, desecrating the earth with sprawling cities. Man's dependence on the natural world became invisible; it became theoretical and intellectual in character, the subject matter of textbooks, monographs and lectures. True, this theoretical dependence supplied us with insights (partial ones at best) into the natural world, but its onesidedness robbed us of all sensuous dependence on and all visible contact and unity with nature. In losing these, we lost a part of ourselves as feeling beings. We became alienated from nature. Our technology and environment became totally inanimate, totally synthetic—a purely inorganic physical milieu that promoted the deanimization of man and his thought.”
