"The epic of evolution not only unifies the natural and social sciences; it bridges science and religion, fact and value, and it smoothly blends the scientifically objective with the culturally relative. The epic also addresses humanity’s most pressing questions. If as a species we are to understand and solve our common problems, if we are to guide our story’s unfolding, we need to understand, in the deep and human way that only story can convey, both our evolutionary past and our future options. We need the epic."
