Gaia and Philosophy

In the 1970s, microbiologist Lynn Margulis and atmospheric chemist James Lovelock developed the Gaia theory, which describes a living Earth: a body in the form of a planet. Fusing science, mathematics, philosophy, ecology and mythology, Gaia and Philosophy, with a new introduction by Dorion Sagan, challenges Western anthropocentrism to propose a symbiotic planet.

Lynn Margulis (1938–2011) was an interdisciplinary evolutionary biologist, author and educator. She was the primary intellectual force in the 20th and early 21st century responsible for the acceptance of the role of symbiogenesis (of archaea and bacteria) played in the evolution of the eukaryotic cells (cells with nuclei) that became plants, animals, and fungi. She also, by underscoring the roles of gas-exchanging bacteria, helped turn James Lovelock’s Gaia hypothesis that the reactive gases of Earth’s atmosphere were physiologically regulated by life away from thermodynamic equilibrium, into a full on theory. Her books, often written in collaboration with her son Dorion Sagan, include Microcosmos: Four Billion Years of Evolution from Our Microbial Ancestors (1987), Mystery Dance: On the Evolution of Human Sexuality (1991) and Slanted Truths: Essays on Gaia, Symbiosis, and Evolution (1997).

Dorion Sagan is author or coauthor of twenty-five books, translated into fifteen languages, including Danish, Japanese, Turkish, Catalan, and Basque, on topics ranging from evolution of the biosphere to the thermodynamics of ecosystems to programmed aging. With Carl Sagan and Lynn Margulis, his parents, he is coauthor of the entries for both ‘Life’ and ‘Extraterrestrial Life’ in the Encyclopedia Britannica. His current interests include poetry and experimental literature. His current projects include poetry, a story collection, and a “metabiography” on his parents’ early romance and connected sciences.
