One of the most critical house rules we must learn is that we are not lords over the planet, but products of its processes; in fact, we are the product of a fifteen-billion-year history of the universe and a four-billion-year history of our earth. We are an intimate and integral part of what we want to know: planetary knowledge is self-knowledge. (Sallie McFague, The Body of God: An Ecological Theology, Kindle edition Loc 190)
