On page 115 of Gaia and God, Rosemary Ruether says what may very well be the crux of her book:
"In the previous two chapters, we have looked both at the heritage of fantasies of world destruction as divine judgment on human evil and at some realities of our actual destructiveness of the earth and its beings. What understandings of the nature of human capacity for evil do Christians bring to the recognition of these threats? Are our ways of naming evil usable in helping us to understand this destructive capacity, or have they actually been an element in promoting this destructiveness and allowing us to turn a blind eye to it?"
