"The modern view [that it is bad for adults to read fairy tales / children’s books] seems to me to involve a false conception of growth. 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. A tree grows because it adds rings: a train doesn’t grow by leaving one station behind and puffing on to the next. In reality, the case is stronger and more complicated than this. I think my growth is just as apparent when I now read the fairy tales as when I read the novelists, for I now enjoy the fairy tales better than I did in childhood: being now able to put more in, of course I get more out."
