IDIOT, n. A member of a large and powerful tribe whose influence in
human affairs has always been dominant and controlling. The Idiot's
activity is not confined to any special field of thought or action,
but "pervades and regulates the whole." He has the last word in
everything; his decision is unappealable. He sets the fashions and
opinion of taste, dictates the limitations of speech and circumscribes
conduct with a dead-line.
-- Ambrose Bierce, "The Devil's Dictionary"
