I'm reading Shivering Sands, a collection of short essays and other writing by British comic book writer Warren Ellis. A lot of it is thoughts on writing and the creative process, both his and others'. In "Comics and Ideas," he talks about how comics educate and transmit ideas. It concludes with this line:
The best fiction, like the best reportage, is about the writer telling the reader where they think they are today, and what they think it looks like.
