"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."
-Toolband.com, official website of rock band TOOL "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. Rare illustrations support a superbly written and meticulously researched text."
-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who wants to learn about Crowley would enjoy this book, while more serious followers will appreciate the previously unpublished biographical details and photographs."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. Thank you, Dr. Kaczynski. I've waited thirty-five years for this."
-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.... Perdurabo is bound to become the definitive biography on Aleister Crowley."
-NewWitch magazine "Aleister Crowley-what a man. I've read several Crowley biographies, and this one takes the prize for most enjoyable and intimate. Mr. Kaczynski has the personal understanding and experience necessary to paint an accurate portrait of Crowley, with all the exciting context in place. Mr. Kaczynski's passion for his subject makes for an informative and potentially life-changing read. Why wade on the shores of such a vast man, when you can dive in? I think Crowley himself would have welcomed such a loving penetration."
-Andrew W.K., musician "I've avidly devoured biographies of Aleister Crowley since my teens, because like other great artists (such as Oscar Wilde), half his genius went into his life. Perdurabo is undoubtedly the most complete and best researched of all the biographies, yet manages to be un-put-downable, tragic as well as laugh-out-loud funny-and best of all, it takes the Magick seriously."
-Peter Lamborn Wilson, author, Green Hermeticism: Alchemy & Ecology "[Perdurabo] is the best and most rigorous treatment of Crowley's life ever published. Essential reading for anyone who wants to know more about this remarkable man."
-Cardiff University Pagan Society Magazine "Dr. Kaczynski has been able to uncover a host of previously unexplored sources which cast new light on Crowley's life and works. Some are presented here for the first time in this revised edition. It is an achievement that deserves praise and I am sure the book . . . will be used by scholars and students for many years to come as an indispensable reference work."
-Dr. Marco Pasi, author of Aleister Crowley and the Temptation of Politics "Meticulously researched and brilliantly written, Perdurabo is a revealing and unflinching look at the complex, enigmatic and always controversial figure known to us as Aleister Crowley. . . Kaczynski has written one of the most enjoyable and riveting reads in recent memory. Newly revised and expanded this is the definitive Crowley biography."
-John Zorn, musician "Perdurabo: The Life of Aleister Crowley provides a definitive biography of the magician and prophet and is a 'must' for any new age collection or library where magic is of interest."
-Midwest Book Review "If you're a collector of Crowley biographies, this is an essential addition to your collection. If you can only afford one Crowley biography, this is the one to get."
-Invisible Basilica "This new edition is essential reading for anyone wanting to understand the Great Beast."
-Clive Harper, author of Notes Towards a Revised Bibliography of Austin Osman Spare
