There is no doubt about it: we are judged by our language as much as (perhaps more than) we are judged by our appearance, our choice of associates, our behavior. Language communicates so much more than ideas; it reveals our intelligence, our knowledge of a topic, our creativity, our ability to think, our self-confidence, et cetera.
Myths hook and bind the mind because at the same time they set the mind free: they explain the universe while allowing the universe to go on being unexplained; and we seem to need this even now, in our twentieth-century grandeur.
