Book excerpt: Modern science and western culture both teach that the planet we inhabit is a dead and passive lump of matter, but as Stephan Harding points out, this wasn't always the prevailing sentiment and in Animate Earth he sets out to explain how these older notions of an animate earth can be explained in rational, scientific terms. In this astounding book Harding lays out the facts and theories behind one of the most controversial notions to come out of the hard sciences arguably since Sir Isaac Newton's Principia or the first major publications to come out of the Copenhagen School regarding quantum mechanics. The latter is an important parallel: Whereas quantum mechanics is a science of the problem--it gave rise to the atomic bomb among other things--Gaia Theory in this age of global warming and dangerous climate change is a science of the solution. Its utility: Healing a dying planet becomes an option in a culture otherwise poised to fall into total ecological collapse. Replacing the cold, objectifying language of science with a way of speaking of our planet as a sentient, living being, Harding presents the science of Gaia in everyday English. His scientific passion and rigor shine through his luminous prose as he calls us to experience Gaia as a living presence and bringing to mind such popular science authors as James Gleick. Animate Earth will inspire in readers a profound sense of the interconnectedness of life, and to discover what it means to live harmoniously as part of a sentient creature of planetary proportions. This new understanding may solve the most serious problems that face us as a species today.
