I know, I know...all of you Neil Gaiman and JK Rowling fans have come here to vent your anger at my supposition that writers in a particular genre are incapable of producing great literature. Well, slow down a minute and hear me out.
First of all, I acknowledge that there are great writers who have written great science fiction. Orwell, Anthony Burgess, Herbert, and Tolkien are some of the ones I would put in that group. BUT, my question really boils down to whether you can classify contemporary storytellers who limit their material to space, swords, sorcery, and the like as writers of great literature.
I see it similarly to this: let's say a song writer only wanted to write songs about birthday cakes.He writes a few albums and people love them (hey, everybody likes birthdays, and the cakes are the best part). Has he really exhibited the skill to be considered a great song writer?
I'm posing this question under the assumption that "great" writers are considered such because a) their work offers itself to expansive interpretation and critical examination, and b) their work is more than just storytelling.
So tell me, who are these fantastic writers? But give me more than just names, anybody can do that. Tell me why they are so fantastic. Back up your statements if you really believe in them. (extra credit for quotes)
