James T. Kirk is named after his mum's 'Love instructor'.
I planned on just leaving that one alone. Gene was obviously experimenting with the pharmaceuticals when he came up with that one.
I never actually read the TMP novelization, but I found what you're talking about at Memory Beta. It strikes me as a sleazy, vulgar kind of futurism. But Robert Heinlein's novels were that way too regarding future sexual mores, which was probably Roddenberry's influence. [And neither of them were cynical and sleazy enough to predict the Paris Hilton/Kim Kardashian career path of parlaying an explicit sex tape into a whole career about being famous for being famous.]
Incidentally, it's been pretty well documented that GR didn't just experiment with illegal drugs. He started smoking pot seriously during STAR TREK's third season if not sooner, and later got addicted to cocaine. Can't say I admire that behavior.
