Writing Gaia tells the story of the scientific collaboration between James Lovelock and Lynn Margulis through an annotated record of their four-decade correspondence. It shows how their partnership proved decisive for the effective development and dissemination of the Gaia hypothesis, work that has transformed contemporary conceptions of nature.
