Bruce I. Kodish is posting a free online version of his Korzybski: A Biography, making his book about the General Semantics author. Of course, Alfred Korzybski was a huge influence on Robert Anton Wilson. (It was Korzbyski who originated the phrase "The map is not the territory.")
Kodish is gradually posting the book online; it is being serialized over the course of several months.
"With this free online edition, not having a readily available copy or the money to buy one can no longer serve as an excuse for not reading it," Kodish says.
If you like what you are reading, Kodish hopes you'll buy your own copy, or ask your local library to order it. (Many libraries do accept suggestions from patrons.)
