What is the author's style in Cosmic Trigger I: Final Secret of the Illuminati by Robert A. Wilson?

The perspective of the book is autobiographical. This works very well in giving a sense of credibility to the often unbelievable and incredible material of the book. Wilson is clear that he is not asking the reader to believe anything. His personal perspective is agnostic, though he deals with many ancient religious faiths, as well as Catholic Christianity. Wilson's perspective is one of cultural relativity. He does not aim for any absolute truths, but instead looks at events from as many cultural standpoints as possible.
