I always kind of laugh when people get into the “Susan’s treatment is proof that C.S. Lewis was a misogynist” thing, because:
Polly and Digory. Peter and Susan. Edmund and Lucy. Eustace and Jill.
Out of the eight “Friends of Narnia” who enter from our world, the male-to-female character ratio is exactly 1/1. Not one of these female characters serves as a love interest at any time.
The Horse and His Boy, the only book set entirely in Narnia, maintains this ratio with Shasta and Aravis, who, we are told in a postscript, eventually marry. Yet even here, the story itself is concerned only with the friendship between them. Lewis focuses on Aravis’ value as a brave friend and a worthy ally rather than as a potential girlfriend–and ultimately, we realize that it’s these qualities that make her a good companion for Shasta. They are worthy of each other, equals.
In the 1950s, there was no particularly loud cry for female representation in children’s literature. As far as pure plot goes, there’s no pressing need for all these girls. A little boy could have opened the wardrobe (and in the fragmentary initial draft, did). Given that we already know Eustace well by The Silver Chair, it would not seem strictly necessary for a patently ordinary schoolgirl to follow him on his return trip to Narnia, yet follow she does–and her role in the story is pivotal. Why does the humble cab-driver whom Aslan crowns the first King of Narnia immediately ask for his equally humble wife, who is promptly spirited over, her hands full of washing, and crowned queen by his side? Well, because nothing could be more natural than to have her there.
None of these women are here to fill a quota. They’re here because Lewis wanted them there.
Show me the contemporary fantasy series with this level of equality. It doesn’t exist.
“I wrote this story for you, but when I began it I
had not realized that girls grow quicker than books. As a result you
are already too old for fairy tales, and by the time it is printed and
bound you will be older still. But some day you will be old enough to
start reading fairy tales again. You can then take it down from some
upper shelf, dust it, and tell me what you think of it. I shall probably
be too deaf to hear, and too old to understand a word you say, but I
shall still be. ― your affectionate Godfather, C. S. Lewis.”
