The article is about the role of God in science fiction, which at first glance seems like a contradiction. After all, SF is all about technological progress and the interesting situations characters get into as a result. Yet looking a layer deeper, the article looks at how SF rejects the Christian God and substitutes its own meaning and in varying ways fails to satisfy. The result is an implied ethic or moral system that's more than a little discombobulated and self-contradictory, though still making for fun stories.
