Hyatt was part of a very specific generation of esoteric authors. Like Robert Anton Wilson, he stressed liberation from our fixed ideas, and was fiercely anti-dogmatic. The last book of his that I read was To Lie is Human, Not Getting Caught is Divine which is basically a series of questions to ask about how much you betray yourself. It’s strange, angry, and the kind of magickal book that doesn’t center around reifying a symbol set so that you can be a pre-fab “adept.”
His voice will be missed.
