Are you left wanting after reading the Wikipedia entry for Aleister Crowley (“The Wickedest Man in the World”) but also daunted by Richard Kaczynski’s 700-page Perdurabo? Colin D. Campbell’s introductory text is the answer. Neither exhaustive nor limpid, Campbell delivers a three-fold primer on Crowley and Thelema within 200 pages: biography, Thelemic philosophy, and Thelemic application. The prose is conversational, opting for passion over pretension even at the expense of an overuse of exclamation marks and a few knee-slappers. There is no complex thesis in the sense of a critical study—if there is a theme that drives the book it is that Thelema is more relevant than ever, with its very foundation built upon individualism sans conflict. Campbell’s subject matter carries with it its own inherent intrigue to which has been attached much fantastic baggage. This text offers a sobering look at a complex and shrouded figure.
