`Daring, exciting, original.' -- Scientific American`Jim Lovelock, a man as inventive and ingenious as he is lively and unorthodox, places a daring hypothesis before the general reader, a kind of geochemical myth for our time.. [His book] is the exciting personal argument of an original thinker caught in wonder. It wins and repays attention.' -- Scientific American`Lovelock writes beautifully. A book that is both original and well written is indeed a bonus. Only a genius thinks of the obvious, and Lovelock deserves to be described as a genius.' -- New Scientist`The breath-taking sweep of his central idea - that the earth is a living, self-regulating organism - poses the most dramatic challenge to scientists, politicians, and environmentalists.' -- Jonathon Porritt
