Gardner also analyzes the flaws in Urantian science and points out many instances of plagiarism in various sections of the book.In a new postscript to this paperback edition, Gardner details recent developments in the Urantia movement, corrects some errors in the original edition, and responds to critical reactions from Urantia believers to his skeptical perspective on the book and the movement.Although there are other histories of The Urantia Book, this is the only one written by a skeptic. Anyone interested in the New Age, cults, or the development of new religions will find much fascinating material in Gardner's thorough overview.
