The Childishness of Science Fiction and Fantasy

Every now and then I meet someone who dismisses my interest in science fiction and fantasy as childish. This has never bothered me particularly and the closed-mindedness that the comment implies has meant that I have never felt the urge to combat the view (I don't seek out closed minded people for friendship). Hence, I have never bothered to attempt a rebuttal.

Recently, I came across an attempt at a rebuttal by C.S. Lewis which I record here as ammunition in case I decide to enter combat.

Critics who treat adult as a term of approval, instead of as a merely descriptive term, cannot be adult themselves. To be concerned about being grown up, to admire the grown up because it is grown up, to blush at the suspicion of being childish; these things are the marks of childhood and adolescence. And in childhood and adolescence they are, in moderation, healthy symptoms. Young things ought to want to grow. But then into middle life or even into early manhood this concern about being adult is a mark of really arrested development: When I was ten I read fairy tales in secret and would have been ashamed if I had been found doing so. Now that I am fifty I read them openly. When I became a man I put away childish things, including the fear of childishness and the desire to be very grown up.

They accuse us of arrested development because we have not lost a taste we had in childhood. But surely arrested development consists not in refusing to lose old things but in failing to add new things? I now like hock, which I am sure I should not have liked as a child. But I still like lemon-squash. I call this growth or development because I have been enriched: where I formerly had only one pleasure, I now have two. But if I had to lose the taste for lemon-squash before I acquired the taste for hock, that would not be growth but simple change. I now enjoy Tolstoy and Jane Austen and Trollope as well as fairy tales and I call that growth: if I had had to lose the fairy tales in order to acquire the novelists, I would not say that I had grown but only that I had changed.

Lewis also has some words for people who worry that science fiction and fantasy can lead readers to lose touch with reality. Specifically, he wrote that the fairy tale

is accused of giving children a false impression of the world they live in. But I think no literature that children could read gives them less of a false impression. I think what profess to be realistic stories for children are far more likely to deceive them. I never expected the real world to be like the fairy tales. I think that I did expect school to be like the school stories. The fantasies did not deceive me: the school stories did. All stories in which children have adventures and successes which are possible, in the sense that they do not break the laws of nature, but almost infinitely improbable, are in more danger than the fairy tales of raising false expectations…

This distinction holds for adult reading too. The dangerous fantasy is always superficially realistic. The real victim of wishful reverie does not batten on the Odyssey, The Tempest, or The Worm Ouroboros: he (or she) prefers stories about millionaires, irresistible beauties, posh hotels, palm beaches and bedroom scenes—things that really might happen, that ought to happen, that would have happened if the reader had had a fair chance. For, as I say, there are two kinds of longing. The one is an askesis, a spiritual exercise, and the other is a disease.
