Gaia, the scientific theory founded by James Lovelock in 1979, embraces the earth as a whole, dynamic entity whose sum is always larger than its parts. While science and theology are often seen as contraries, which negate or dilute one another, Gaia theory harmonizes both systems of thought. Sacred Gaia cogently describes Gaia theory's analysis of human and earthly evolution. Anne Primavesi's remarkable, effortlessly coherent book helps us to recognize the sacredness of our origins and our responsibility for the future.
