So I love the best of his work, but I do not belong to the school (Sarah A. Hoyt may be the latest) that appears to believe that his flatulences smelled like Chanel #5. (I think they're a lot closer to the truth than the people who believe he was a fascist.) I like an idea I encountered in the writings of Edward Hall, of a tribe in Mexico that doesn't have global categories of Sane and Insane but believes that some people don't function well in some situations. It works at the other end of the scale, with Heinlein and with the only other writer who comparably influenced me, Robert Anton Wilson, who programmed me in ways that were not obvious for months or even years, but who from the beginning seemed neither feminist nor elitist enough.
Do drop in on Tor's Heinlein symposium and buy the bio.
