All ethics so far evolved rest upon a single premise: that the individual is a member of a community of interdependent parts.
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 LeopoldNo important change in ethics was ever accomplished without an internal chage in our intellectual emphasis, loyalties, affections, and convictions.
