"History is governed by those overarching movements that give shape and meaning to life by relating the human venture to the larger destinies of the universe.  Creating such a movement might be called the Great Work of people.... The Great Work now, as we move into a new millennium, is to carry out the transition from a period of human devastation of the Earth to a period when humans would be present to the planet in a mutually beneficial manner."

Thomas Berry, The Great Work
