The first book I read of his was "Psybermagick" - his first attempt to marry magic and science. A very exciting book for me. I should read it again."Liber Null & Psychonaut" and "Liber Kaos" by Peter J. Carroll. Here finally was somebody who talked business, not like the old fuddy-duddies like William G. Gray or W.E. Butler where you'd ask yourself constantly what magic was actually for, irreverent but dead serious, fresh but sophisticated, no trace of bullshit anywhere. "Liber Null" (re-)introduced the Spare method of sigil magic and contains some nifty original ideas; it's the book that got me started in magic, and I'm forever grateful for that.
Don't feel bad. I recall Charles Hartshorne's office had an entire tier on three sides devoted to books on "process theology" that authors sent him and that he had never read. He was polite enough to wave a hand and say, "I'll get to those someday." (He was then over ninety.)The first book I read of his was "Psybermagick" - his first attempt to marry magic and science.

I had some correspondence with him about my work, since I thought he would be one of the few people to really understand. Alas, he didn't actually read the copy I sent him and was also a bit of a dick :-(
