Sutin, Lawrence. Do What Thou Wilt: A Life of Aleister Crowley. New York: St. Martin’s Press. 2000.
For better and worse, Aleister Crowley is one of the pivotal figures in the recent history of magic. He is also one of the more inscrutable, and the difficulties of his deliberate misdirections are multiplied by the revulsion that his actions and ideas can create. He proclaimed himself the divinely inspired messenger of a vast cultural shift and a magician of the highest achievement, but was widely reviled and - much worse from his perspective - often ignored. Capturing the breadth of these paradoxes in a single personality is not easy, and Sutin tackles it well in his biography of Crowley, which makes an excellent introduction for anyone trying to gain the necessary perspective on Crowley and his work.
