Cosmic Trigger II: Down to Earth is the second book in the Cosmic Trigger series, a three-volume autobiographical and philosophical work by Robert Anton Wilson. First published in 1991, Cosmic Trigger II continues where Cosmic Trigger I: The Final Secret of the Illuminati left off, as well as being a set piece in itself. Wilson continues the Illuminati-based synchronicities that have taken place since Cosmic Trigger I was first published. The book is an exploration into the future of cyberspace; the peculiarities of Irish jurisprudence; links to the Mafia, the CIA and the Catholic Church; anal-eroticism in the White House; the Dog Castrator of Palm Springs and more. The book combines humour, twists in logic and zen-like koans to get its messages across.
