Query: Comprehensive Introduction

Mr. Peterson has taken a subject with vast implications for the future and has sifted information about it coming from worldwide sources into a short, highly readable introductory volume. He succeeds in making comprehensible some of the more unusual stories in many of today's headlines, and sympathetically relates his own connection to the subject matter. An ideal starting point for those seeking a lucid explanation of the future of global culture, and the manner in which we are to arrive at it. Also a wonderful sort of alternative commentary on the events of our times.
