In early 20th-century England, Aleister Crowley (1875-1947) was considered “the wickedest man in the world.” Today he"s seen as a prophet, a master of the occult, and a spiritual pioneer--and his reputation just keeps on growing. This new biography, written with the cooperation of leading Crowley scholars and including new revelations from Crowley"s grandson, displays the full scope of the man"s many achievements as poet, explorer, spiritualist, wartime spy, and a thinker as significant as Jung, Freud, or Einstein.
