The rock band The Doors. Maybe the best thing about the band was that it took its name ultimately from the wonderful William Blake quoted cited at the beginning of RAW's essay. Public domain photo, source.
I tend to classify Robert Anton Wilson's work in terms of three main periods: The early years (when he wrote for Paul Krassner's The Realist and other publications, middle period "classic" RAW (including Illuminatus! and Cosmic Trigger, and the later period of books such as TSOG.
But "Sex Education for the Modern Liberal Adult," tends to suggest that not too much should be made of such classifications, as it is sharply written and just as good as anything written during the "classic period."
And it, and the other pieces selected by Chad, make me wonder how much other really good stuff is out there, as piece by piece, it seems to me that Natural Law Or Don’t Put A Rubber On Your Willy And Other Writings From A Natural Outlaw is as consistent in quality as Email to the Universe, which I regard as an exemplary collection.
"But to see your own blood draining out ... " I never minded giving blood (which I stopped doing after I was made sick from hepatitis by eating a doughnut, from a shop which had employed someone who was sick and thus managed to spread it to quite a few people), but when I had a nosebleed recently, it was startling to me!
I love the sentences about how millions of "cycles, epicycles, rhythms, and processes" make up our day to day existence, including such things as spring, summer, fall and winter. I confess that moving from Oklahoma to Ohio has reinforced by loathing for cold weather. But there's also something to be said for the sharply drawn four seasons in the northern part of the U.S.
The church's loathing of sex inspired the same sort of strong dislike in me that it inspired in RAW, although in fairness the modern church seems much more sensible than the early church, when loathing of the body was much worse. (There is apparently controversy over whether the early Christian scholar Origen castrated himself. St. Paul's statement that it is "better to marry than to burn" would seem to suggest that lust is unnatural or sinful.)
"A Zen master once summed up Buddhism in the one word, 'Attention'." This is another example of how RAW understood Buddhism rather well; this is a good one-sentence summation of mindfulness, which is essentially the practice of Theravada Buddhism.
The remarks about the "oceanic experience" seem to suggest a kind of mysticism that does not conflict with science. Are we "all stumbling into this experience constantly," as RAW asserts, or do only some of us do? For an essay that's only a few pages, this seems like a remarkable manifesto.
