Slightly over half of this book is about Scientology, with good material on the early days of Dianetics, some amazing and hilarious material about OT wins, life at Saint Hill and aboard the ships, as well as good coverage of various Scientology offshoots, the E-Meter, and more. As organized religion has declined, new surrogate beliefs, many of them based on pseudoscientific rationality, have sprung up. These are what Dr. Christopher Evans calls the cults of unreason, man's attempt to fit technology to a religion-like belief. In many of these cults naivete and sophistication work side by side.
