"I am speaking of the life of a man who knows that the world is not given by his fathers, but borrowed from his children; who has undertaken to cherish it and do it no damage, not because he is duty-bound, but because he loves the world and loves his children; whose work serves the earth he lives on and from and with, and is therefore pleasurable and meaningful and unending; whose rewards are not deferred until "retirement," but arrive daily and seasonally out of the details of the life of their place; whose goal is the continuance of the life of the world, which for a while animates and contains them, and which they know they can never compass with their understanding or desire." 
-Wendell Berry
