Happy Birthday, C. S. Lewis

"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."
