Berry believes we stand at a defining moment in history, one in which the earth itself calls out to us to embark upon a resacralization of nature, a new ecological beginning. Berry is our conscience, our prophet, our guide. He speaks to what is best within us, in a voice that is inclusive, ecumenical, generous, and wise. His Great Work should -- and must -- be ours. -- Chet Raymo, Orion A visionary book, full of insight, erudition, and cogency. -- Ursula Goodenough, professor of biology, Washington University
