The scientist who influenced Laudato Si, and who serves at the Vatican's science office, seems to believe in Gaia, but not in God.
St. Francis of Assisi’s hymn Laudato Si’ spoke of “Brothers” Sun and Fire and “Sisters” Moon and Water, using these colorful phrases figuratively, as a way of praising God’s creation. These sentimental words so touched Pope Francis that he named his encyclical after this canticle (repeated in paragraph 87 of the Holy Father’s letter). Neither Pope Francis nor St. Francis took the words literally, of course. Neither believed that fire was alive and could be talked to or reasoned with or, worse, worshiped. Strange, then, that a self-professed atheist and scientific advisor to the Vatican named Hans Schellnhuber appears to believe in a Mother Earth.
The Gaia Principle, first advanced by chemist James Lovelock (who has lately had second thoughts) and microbiologist Lynn Margulis in the 1970s, says that all life interacts with the Earth, and the Earth with all life, to form a giant self-regulating, living system. This goes far beyond the fact that the Earth’s climate system has feedbacks, which are at the very center of the debate over climate change. In the Gaia Principle, Mother Earth is alive, and even, some think, aware in some ill-defined, mystical way. The Earth knows man and his activities and, frankly, isn’t too happy with him. This is what we might call “scientific pantheism,” a kind that appeals to atheistic scientists. It is an updated version of the pagan belief that the universe itself is God, that the Earth is at least semi-divine — a real Brother Sun and Sister Water! Mother Earth is immanent in creation and not transcendent, like the Christian God.
