"From a historical perspective, Perdurabo is the finest work
on Crowley to date."
-Peter J. Morris, writer and blogger
"Although there have been several authoritative (and relatively impartial) bios of the occultist Aleister Crowley published in the last decade, in my opinion there is one that is definitely a cut above the rest. This would be Perdurabo by Richard Kaczynski, PhD. As 'The definitive biography of the founder of modern magick,' Kaczynski's revised and expanded edition of his 2002 offering is tirelessly researched (20 years!), highly detailed and loaded with photos, many of which are quite rare."

"Richard Kaczynski's Perdurabo: the Life of Aleister Crowley is the one biography that is absolutely necessary for anyone who wishes to know more about one of the most creative, seminal, and misunderstood figures of the last hundred years."
-David Tibet, founder of Current 93
"A brilliant essayist, a superior poet, and an extraordinary artist, mountaineer, and explorer, the Crowley presented in these witty and erudite pages is at once shocking, wise, egocentric, petty, inspirational and, most importantly, real. Roundly rejecting the pantomime villain at the center of previous biographies and deeply suspicious of the nonsensical hero-worship of some of his modern followers, Kaczynski's portrait of Crowley is balanced and well-informed."
-Paul Feazey, LAShTAL.com
"Perdurabo is a magnificent biography not only on the colorful and fascinating figure himself, but on the occult, eastern religions, sexuality, and the attempt to apply the rigors of the scientific method to the so-called occult. Kaczynski does justice to Crowley's life and thought, solidly placing him with other great spiritual development figures. Anybody who wants to learn about Crowley would enjoy this book, while more serious followers will appreciate the previously unpublished biographical details and photographs."
-Sacramento Book Review
"This is not only the most carefully-researched, detailed, and informative biography of Crowley yet written but also a remarkable insight into the nature of magic itself."
-Ronald Hutton, author of The Triumph of the Moon and Blood and Mistletoe: The History of the Druids in Britain
"Several recently-published biographies of Crowley do justice, for the most part, to his life and works. But their offerings now stand like skeletal frames of unfinished houses next to Kaczynski's magnificently constructed edifice. Every brick is set in place with the mortar of meticulous research and insight."
-Lon Milo DuQuette, author of The Magick of Aleister Crowley
"At long last, the world has a balanced and readable biography that reflects how magick shaped every facet of Aleister Crowley's life. And Dr. Kaczynski doesn't dismiss magick as humbug or mumbo-jumbo but validates it as a legitimate method of spiritual development meriting serious study."
-Christopher S. Hyatt, PhD, author of Undoing Yourself
"Richard Kaczynski uses a novelist's touch to make this exceptionally well-researched book read like an adventure story. For the serious student of Ceremonial magick or anyone curious about the truth behind all those weird stories, it's essential reading."
