Richard Metzger interviews the late Dr. Mario Pazzaglini, the author of Symbolic Messages: An Introduction to a Study of Alien Writing. Dr. Pazzaglini was investigating the possibility of Alien writing by studying hundreds of artifacts and interviewing individuals who claimed to have been contacted by alien intelligences. He presents a very balanced, rational, and informed view about the escalating reports of written communication alleged to have originated from non-human sources. Highly Recommended.
