Ever read The Chronicles of Narnia? The thing that Professor Kirk is most famous for saying is, "It's all in Plato! What DO they teach in those schools these days?"
   One of my favorite examples of that thinking is a quote by another Narnian character, Puddleglum, when told by the wicked underground queen that Narnia and everything he knows of it is just a story, just a game.  "Suppose we HAVE only dreamed or made up all those things - trees and grass and sun and moon and stars and Aslan himself. Suppose we have. Then all I can say is that, in that case, the made-up things seem a good deal more important than the real ones.  ........ four babies playing a game can make a play-world that licks your real world hollow. That's why I'm going to stand by the play world. I'm on Aslan's side, even if there isn't any Aslan to lead it. I'm going to live as like a Narnian as I can, even if there isn't any Narnia."

   What  Plato said was, "But perhaps there is a model of it (the perfect city) in heaven, for anyone who wants to look at it and to make himself its citizen on the strength of what he sees. It makes no difference if it is or ever will be somewhere, for he would take part in the practical affairs of that city, and no other."

   Deep respect to Mr. Lewis, for  such a good story. And gratitude for the fact that we can see things that aren't right in front of us, we can see ideas, and count them as even more important than the physical things around us. Life is good.
