We’ve all probably had the experience of reading a great SF novel and lending it to a friend—a literate friend who adores A.S. Byatt and E.M. Forster. Sometimes our friend will turn their nose up at the cover, and we’ll say no, really, this is good, you’ll like it. Sometimes our friend does like it, but often we’ll find our friend returning the book with a puzzled grimace, having tried to read it but “just not been able to get into it.” That friend has approached science fiction without the necessary toolkit and has bounced off. It’s not that they’re stupid. It’s not that they can’t read sentences. It’s just that part of the fun of science fiction happens in your head, and their head isn’t having fun, it’s finding it hard work to keep up.

Smart stuff, worth thinking about and discussing.
