Fantasy and science fiction author and political activist Steven Brust (previously) was this year's Guest of Honor at Philcon, an excellent Philadelphia-area science fiction (I have also had the privilege to be Philcon's GoH, and it's a great con); his guest of honor speech is entitled Truth as a Vehicle for Enhancing Fiction, Fiction as a Vehicle for Discovering Truth, and he's posted a transcript to his blog. It's a fascinating examination of how philosophy and fiction mesh, and particularly how "pulp" forms of fiction like fantasy and science fiction both convey philosophical ideas and benefit from their inclusion -- and how people who claim not to have a philosophy or to adhere to "isms" are in fact, espousing a philosophy. So now we turn it around, because yeah, we really can can discover truth, understand reality better, through fiction, and that’s how we create fiction that hits hard, that punches, that stays with us.
