Martin Wagner and Jesse Walker are reporting that a 72-page essay by Robert Anton Wilson on Aleister Crowley has been located at the Harvard University library. (Martin was the first to tell me about it, but Jesse has supplied details.) UPDATE: Jesse says I give him too much credit; see the comments.
The essay is entitled "Do What Thou Wilt," and it is unclear what relationship it has to Lion of Light, the book-length piece on Crowley that RAW planned to publish. Rasa at the RAW Trust/Hilaritas Press has been notified and is pursuing the matter.
"It is an extensive survey of the biography and philosophy of Aleister Crowley, with the last two pages giving details and opinions of two of Wilson's earlier books."
