"Anatomy of a Phenomenon" is refreshingly candid and erudite. Vallee's commentary reminds me somewhat of Carl Sagan's views on extraterrestrial intelligence in the 1960s. "Anatomy" was written shortly before what Colin Wilson termed Vallee's "labyrinthine pilgrimage." The suspicion inherent on every page of "Anatomy" is that UFOs are ET vehicles. Now Vallee, like Mack and Strieber, thinks the ET hypothesis is too simplistic.
