Query: my favorite Farmer

I read most of Phillip Jose Farmer's books between 1978 and 1985. Recently I started reading them again. The intervening years may have caused my preferences to change. After rereading a lot of his stories, I have revised my opinions. I think Two Hawks is his best novel in several respects: the way he developes believable speculative science; and the way the history, linguistics and ethnology of the parallel earth were developed.
