Margulis apparently considered Gaia: A New Look at Life on Earth insufficiently robust in the cause of Gaia’s scientific defense. She now took a more proactive role in sponsoring a book by Lovelock that would meet her own standards. Around June 1983, Lovelock began a letter to Margulis: “Here is a copy of my formal letter to the Commonwealth Fund. Whether or not anything comes of it I am so grateful to you for bringing it to my attention. It is just what I need to keep out of mischief next year” (Letter 152). Recorded here is the inception of what is often considered Lovelock’s best concerted presentation of Gaian science. Not coincidentally, The Ages of Gaia (Lovelock 1988) developed under Margulis’s editorial eye.
