...to any one for whom wild things are something more than a pleasant diversion, (conservation) constitutes one of the milestones in moral evolution.
Aldo LeopoldWe all strive for safety, prosperity, comfort, long life, and dullness. The deer strives with his supple legs, the cowman with trap and poison, the statesman with pen, the most of us with machines, votes, and dollars. A measure of success in this is all well enough, and perhaps is a requisite to objective thinking, but too much safety seems to yield only danger in the long run. Perhaps this is behind Thoreau's dictum: In wilderness is the salvation of the world. Perhaps this is the hidden meaning in the howl of the wolf, long known among mountains, but seldom perceived among men.
Aldo LeopoldThis song of the waters is audible to every ear, but there is other music in these hills, by no means audible to all. On a still night, when the campfire is low and the Pleiades have climbed over rimrocks, sit quietly and listen, and think hard of everything you have seen and tried to understand. Then you may hear it - a vast pulsing harmony - its score inscribed on a thousand hills, its notes the lives and deaths of plants and animals, its rhythms spanning the seconds and the centuries.
Aldo LeopoldAll ethics so far evolved rest upon a single premise: that the individual is a member of a community of interdependent parts. . . The land ethic simply enlarges the boundaries of the community to include soils, waters, plants, and animals, or collectively: the land.
