Passport to the Cosmos provides the most sophisticated and insightful analysis to date about alien abduction phenomenon. [Mack deserves] thanks for holding his ground in the face of critics. - Michael Zimmerman, Ph.D., Professor of Philosophy, Center for Humanities and the Arts. University of Colorado Dr. Mack is one of the more credible writers and researchers in the UFO scene and a man who has earned the right to be accorded some consideration. - Mensa Bulletin: The Magazine of American Mensa Review From Publishers Weekly Here is a fascinating foray into an exotic world. From Harvard psychiatry professor and Pulitzer prize-winning author John Mack comes a second book (after Abduction) based on accounts by people who claim to have been abducted by aliens. While he fudges the question of whether the aliens are real in a strictly material sense, he insists that the experience is real for the abductees, in the way that shamans' spiritual journeys are real to them; indeed, a couple of his interviewees are shamans. He focuses on the newly emerging spiritual importance of the alleged abductees' message. Their reports, Mack believes, reveal much about human culture and the future of the human race. In extensive interviews with Mack, those who claim to have been abducted report that the aliens are especially motivated by questions of ecological destruction, and that they may even be survivors of a destroyed civilization seeking to breed hybrid children with humans to ensure the survival of both the human race and their own. Overwhelmingly, the abductees state that the aliens visit Earth to warn us that our cavalier tree-cutting, water-polluting, trash-dumping habits will have dire consequences if we do not change our ways. Abductees are left with not only a profound caring for the environment, but with a sense that they have encountered creatures sent by whatever power rules the universe. They particularly find that their experiences resonate with Native American religions. This discussion leads into what is possibly the most intriguing section of the book, the examination of sex between humans and aliens-great sex, by numerous accounts. But as a serious investigation into a mystifying experience, Mack's account poses questions begging for answers. Review From Library Journal Mack, a Harvard University psychiatrist and Pulitzer Prize-winning biographer of T.E. Lawrence, created an academic stir with the publication of Abduction: Human Encounters with Aliens (1994), in which he argued that tales of alien abduction were true. As a result, Harvard warned him to adhere to its standards of conduct for clinical research. In this follow-up, Mack, still undaunted, argues that our knowledge of reality needs to change and that scientific rationalism alone cannot explain the alien abduction syndrome. He examines traditional views of reality, the implications for humanity in light of the abduction phenomenon, and the traumatic effects on experiencers or abductees. Mack's work with indigenous people-shamans and medicine men and women-suggests that the phenomenon is not simply a product of Western imagination. This veritable handbook of New Age philosophy will find a readership in most public libraries.
