Peter

“It must be understood that while the majority of Zoon cannot lie they have great respect for any Zoon who can say that the world is other than it is, and the Liar holds a position of considerable eminence. He represents his tribe in all his dealings with the outside world, which the average Zoon long ago gave up trying to understand. Zoon tribes are very proud of their Liars. Other races get very annoyed about all this. They feel that the Zoon ought to have adopted more suitable titles, like “diplomat” or “public relations officer.” They feel they are poking fun at the whole thing.”
