In "Spook," Mary Roach is at her witty best in discussing ways that scientists have tackled reincarnation, spirit mediums and the search for the location and weight of the soul. Roach combines a wicked wit and a skeptical, scientific attitude that is entertaining and informative. The worst thing I can say about the book is that her fascinating subject matter encourages the reader to devour the pages, while her witty asides and commentary require that the reader slow down. It's a little like eating ice cream ON a hot day -- you want to gobble down the treat, but have to slow down to avoid the brain freeze.
Roach takes us to India to visit a scientist who "investigates" reports that the recently dead have reincarnated into newborns from neighboring villages. The scientist, who claims to be impartial and impervious to bias, clearly could use a bit more skepticism and rigor. Roach takes the opportunity to discus how a culture (like India's) that takes reincarnation for granted is more likely to read their beliefs into the random expression of four-year-olds that would we in the West. Of course, we tend to see the divine visage in flapjacks, so who is to judge?
Roach does a nice job of investigating NDEs (near death experiences) and discussing the truth about these strange phenomena. Are NDEs real? Are they imagined? Whatever could they mean? Ever the skeptic, Roach takes them with a grain of salt while holding out a slim hope that they turn out to be real. A laptop computer, laid on a high shelf in a hospital emergency room and generating random images for the next soul-traveler, should eventually provide an answer.
Roach's chapters on the mediums of the late 18th and early nineteenth centuries were especially interesting to me. Rarely do you get to see a competent skeptic take on the outlandish manifestations -- trumpets, moving tables, taps and blasts of wind -- that were part and parcel of séances during the period. Roach takes on the bizarre phenomenon of ectoplasm -- a material supposedly produced by mediums from contacts with the other world. Credulous scientists were fooled by the appearance of this matter, and could not explain it. Other scientists showed conclusively that the material was simple cloth or animal tissue that had been secreted by the mediums on their persons. Roach's description of a trip to Oxford to examine purported ectoplasm led her to determine (by smell) in which bodily orifice the medium secreted the material. Ewww!
Lest we think that all scientific lunacy about death occurred decades ago, Roach tells about scientists who attempt to calculate, using Einstein's equation equating matter and energy, the energy lost when a soul leaves a human body at death. Ever the materialists, these worthies seems immune to the possibility that the soul could be non-corporeal.
Roach, in "Spook," is funny, irreverent and informative. A great read, one bite at a time. less
