The Witch of the North seemed to think for a time, with her head bowed and her eyes upon the ground. Then she looked up and said, “I do not know where Kansas is, for I have never heard that country mentioned before. But tell me, is it a civilized country?”

“Oh, yes,” replied Dorothy.

“Then that accounts for it. In the civilized countries I believe there are no witches left, nor wizards, nor sorceresses, nor magicians. But, you see, the Land of Oz has never been civilized, for we are cut off from all the rest of the world. There we still have witches and wizards amongst us.”

—L. Frank Baum, The Wizard of Oz
