anon for this-
Harlan Ellison is a name I recognize well from the library shelves, but I read almost none of his books, and know nothing about him.
I was going to say I read none of his books, but when looking at his wikipedia page (te get a better idea of what you were talking about) I noticed he wrote “A Boy and His Dog” which I read as a kid (horrible book – not recommended).
Based on Ellison’s Hugo collection, he seems to have earned a little positive self-approbation.
I read many of Asimov’s fiction books – the “Lucky Starr” kids series, miscelaneous books like “Pebble In The Sky”, the original Foundation series, the Robot series, many more that I can’t remember right now – all at least very good, most excellent. The fourth Foundation book he wrote years later was not very good.
I find it surprising he didn’t write on philosophy, since he had a philosophical streak in many of his books and short stories (i.e. “Nightfall” for one).
