The author of The Phenomenon of Man reconciles passionate faith with the rigor of scientific thinking. With his unique background as a geologist, paleontologist, and Jesuit priest, Pierre Teilhard de Chardin was a powerful exponent of the view that scientific theories could comfortably coexist with religious faith. To this day, his ideas provoke passionate debates in communities that view science and faith as necessarily separate ideologies. In this collection of nineteen essays, Teilhard seeks to illuminate a middle ground between science and religion that he felt both disciplines could accept. He explores the Fall and original sin, the possibility of life on other planets, and the role that God may have played in the process of human evolution, successfully challenging contemporary theologians to rethink their views of the universe and its creation. “Like other great visionary poets—Blake, Hopkins, Yeats—Teilhard engages the reader both intellectually and sensually.” —The Washington Post Book World “An excellent blend of theological speculation with practical or ascetical application.” —Catholic Telegraph
