A guest from another star to our solar system could use a simple spectroscope to explore the atmospheres of the planets, and wind up that while Venus and Mars, which both have carbon dioxide atmospheres, do not have life, Earth, with its oxygen-rich atmosphere, must have, and is alive. Today, there are many different views of Gaia, ranging from the semi-religious way in which many people have latched on to the idea of the planet as a living - Mother Earth, to oppositions from some scientists who regard the whole thing as utter nonsense. Interpreting the Earth as a superorganism in this book represents something transcendentally new. In fact, it implies a theory, which is susceptible to being tailored and treated with rigorous metaphysical, mathematical and scientific means. It particularly calls for a new ontology, which we can qualify as an ecometaphysics, or ecoontology of an interconnection and interelatedness of all things.
