Collin Wilson touched on Crowley's pedophillia in The Occult: A History. Crowley's own writings seem to allude to it as well, "She (Rose Kelly) hath given Her two year old bastard boy to her lover’s whim of sodomy...She hath tounged Her five-month old girl, and asked its father to deflower it." I'd say if he wasn't a pedophile, he certainly fantasized about it, it seems.
