Margaret Mead, Gregory Bateson, and the rest of their peers made interesting history and caused so much harm. The nepotism in the early psychedelics field, with sons named after their fathers taking on their work, made the individual histories hard to follow at times. While detailed in the telling of history, I wanted more information about the events and individuals addressed over the decades discussed. Breen is good at picking up the loose ends of stories, making sure to finish the stories and histories related to their work in psychedelics, of those discussed early on. It was interesting to see the shift in perspective of scientists as they became addicts, gurus, g-men, spies, strategists, and disenfranchised maniacs. Horrifying that people like that seem to have been at the heart of our country from the start.
