> There are a few non-fiction books, though I'm blanking on the key author's name. I don't know if he is who you had in mind, but Robert Anton Wilson -- who was one of the writers on the Illuminatus! trilogy -- has at least two non-fiction books on it. One is Prometheus Rising, the other is Quantum Psychology: How Brain Software Programs You and Your World. They are both a series of essays with exercises at the end of each chapter.

Quantum Psychology is both written in and a guide to E-Prime, https://en.wikipedia.org/wiki/E-Prime https://en.wikipedia.org/wiki/E-Prime (Edit, via wiki: 'E-Prime refers to a version of the English language that excludes all forms of the verb to be, including all conjugations, contractions and archaic forms. Some scholars advocate using E-Prime as a device to clarify thinking and strengthen writing.')
