"There is both good and evil in the world, but the line separating them runs not between nations or institutions or groups or even individuals; the line that separates good and evil runs through the core of each nation, each institution, each group, and, most tellingly, through the core of each human being, through each one of us. Cutting through each one of us is the reality of our own limitation. “‘There is a crack in everything God has made,” Emerson observed, and—not least of all—in each one of us."

— Ernest Kurtz and Katherine Ketcham, The Spirituality of Imperfection
