This book steps into the void between New Age nonsense and scientific disdain. With contributions by Carl Sagan, Martin Gardner, Philip J. Klass, Marc Medoff, J. Gordon Melton, and many others, this analysis and examination of the New Age is thorough, rigorous, and fair - and offers multi-faceted and balanced explanations about a movement that, until now, has been far too slippery to be pinned down.
