Essay by Callicott from DEFENDERS
Magazine, November / December 1992 issue
Excerpt:
Why has Aldo Leopold had so much influence on the environmental
movement, and why has his slender book of essays, A Sand County Almanac,
become, in the words of Wallace Stegner, "almost a holy book in
conservation circles"?
Perhaps because Leopold was a scientist, poet and philosopher, three
gifts rarely found in one individual. As a scientist, he spoke with
experience and authority. His way with words enabled him to communicate
memorably with nonscientists. And he could not help but consider the
philosophical and ethical implications of ecology.
In Leopold's integrative thinking, ecology was never
just another arcane science. Nor was it simply a fund of information
useful for more efficient exploitation of natural resources. To him,
ecology offered a new way to perceive and order the natural world.
Moreover, Leopold found his values changing as his ecological
understanding deepened. Ecology, he realized, was also pregnant with
revolutionary ethical precepts, and these he deftly brought to light in
the Almanac. Of all his contributions to modern conservation, the
fathering of environmental ethics was perhaps his greatest.
The last of Sand County's three parts is
entitled "The Upshot," and the last piece in that part is
"The Land Ethic." There Leopold sketched out in broad strokes
the moral implications of ecology. He called for a wholesale change in
the "current philosophy of values," which continues to this
day to be based largely on utilitarianism, as articulated by 18th
century philosopher Jeremy Bentham. According to Bentham, human
happiness is the greatest good and all other living things are mere
means to that end. Human beings have "intrinsic value" (we are
valuable in and of ourselves) and everything else has "instrumental
value" (or value because of its utility or use)...
