Ptolemy Tompkins is the author of Paradise Fever (a memoir focusing on the years in the mid-seventies when his father, Secret Life of Plants author Peter Tompkins, became obsessed with finding the lost continent of Atlantis in the waters off Florida), The Beaten Path (an examination of the good and not-so-good things that happen when one takes the teachings of popular modern wisdom authors like Alan Watts and Carlos Castaneda too seriously) and This Tree Grows Out of Hell (a spiritual history of the Maya and Aztec cultures focusing on their disturbing preoccupation with bloodshed). For just under ten years he was an in-house editor at Guideposts and Angels On Earth, and is currently a contributing editor at both magazines.
It was while working at Guideposts and Angels that he got the idea for his book, The Divine Life of Animals, which examines the question of whether animals have souls. He writes a monthly column for Beliefnet.com.
