Prometheus Rising by Robert Anton Wilson describes the human mind with the eight-circuit model of Leary. Wilson explains how tunnel-realities are formed:

“Whatever the Thinker thinks, the Prover proves”

And he makes it clear that his book is itself a tunnel-reality written in English to appeal to the third circuit semantic logic of the reader. It is a book to help the reader escape tunnel-realities which is itself a tunnel-reality. That is meta! Meta-programming the reader’s own mental software to become aware of infinity is the subject of chapter 14. Topics include everything from physics to strange loops to Leary to UFOs to evolution to yoga.

Attempting to elevate the reader’s awareness to a higher state with verbal or written language is like trying to “fit a camel through the eye of a needle.” Hence the studying of Koans by students of Zen, religious fasting to deprive the mind, etc… Read Alan Watt’s The Way of Zen for more on that. This book was written by Wilson, who, in his terminology might be a thinker on a higher circuit, trying to communicate to the vast mass of humanity living on the 1st – 3rd circuits. Once a critical mass of humanity becomes aware, society will under-go a quantum leap in development. With that being said, the book is only an introduction, a starting point for a new perspective to grasp human psychology and human existence as “domesticated primates” on Earth. What is left is for the reader to explore the exercises at the end of each chapter and spread the word.

But some may argue that Wilson is himself subject to the same principals he outlines in his book; yes indeed, perhaps the entire book is the ramblings of a man attempting to brainwash his readers into having thoughts of freedom and liberty…
