This eminently readable book explores the symbolic and psychological aspects of numbers. The author shows that numbers are far more than the symbols we use for counting, for they are founded on a deep psychic structure that underlies many of our thoughts and behaviors. Numbers also give shape and meaning to our socially constructed world. Enigma reads like a mystery novel as it traces the first appearance of numbers in Paleolithic times through Eastern and European countries and Meso-America. And while the author does consider the mathematical properties of numbers, the book is aimed at the intelligent layperson with an interest in the more esoteric and psychological aspects of mathematical ideas. It will also have a strong appeal to those interested in popular science and in Jungian ideas. Each of the numbers, from zero to ten, is given its own chapter and there are also chapters on number symbolism in the Kabbalah, divination, music, religion, and mythology.

According to several recent polls, more than 80 percent of Americans believe in life after death. Of those, many adhere to their beliefs because of religious faith. Beyond religion, though, there is increasing scientific examination of life after death hypotheses. Both religious and secular believers are more frequently using empirical research to answer the key questions of how consciousness may transcend corporeal life and death. These essays from leading survival theoreticians scientifically assay the issues and evidence. Interdisciplinary in nature, it covers diverse topics including the origins of life after death hypotheses; theoretical, methodological and empirical approaches to afterlife research; hallucination experiences; evidence for consciousness survival; birthmarks and previous-life memories; suicide; and spirit participation. Concluding chapters discuss the future of afterlife research and offer a new interpretation of consciousness survival.
