I wonder if Clive Thompson isn't lumping science fiction with fantasy in his Wired column Clive Thompson on Why Sci-Fi Is the Last Bastion of Philosophical Writing. He says, "Teenagers love to ponder such massive, brain-shaking concepts, which is precisely why they devour novels like Philip Pullman's His Dark Materials, the Narnia series, the Harry Potter books, and Ender's Game. They know that big-idea novels are more likely to have an embossed foil dragon on the cover than a Booker Prize badge." I'm not going to dispute his basic argument, but "an embossed foil dragon" usually says fantasy to me, not science fiction.
Now, students, after you've read Mr. Thompson's column, think about how his theory that "Science fiction is the last great literature of ideas" applies to children's literature. Is there all that much science fiction being written for children these days? Or is it primarily fantasy? And should those two genres be lumped together?
