Hey I've known The Mule five or six years I think via email and I never made that connection between the Asimov character and the flesh and blood character!
I used to be a big Science Fiction person in my youth (gad I really do feel as if my youth is gone, scary.) Some favorites were Pohl and Kornbluth, Anderson, Farmer, Niven, Delaney, Zelazny. . . .Though the deeper and deeper I got into Philip K. Dick (he was one of the first since I read the Zap Gun at age 12 in 1967) I moved out of the genre more into hard-boiled psychodrama and mysteries, deep into the generation of writers that Hammett and Chandler spawned, and true originals like Jim Thompon and David Goodis and Horace McCoy. . . and totally genrebusting people like Henry Miller and Thomas Mann. Then I embarked on a study of gnosticism and early Christianity that was partially fueled by PKD, and into a long period of mainly reading nonfiction and I'm mostly still in that phase. . . .
