Jack Vance Quote

Kergan Banbeck threw up his hands, turned once more to the sacerdote. How can I halt his nonsense? How can I make him see reason?
The sacerdote reflected. He speaks not nonsense, but rather a language you fail to understand. You can make him understand your language by erasing all knowledge and training from his mind, and replacing it with patterns of your own.
