Civilization is Words

A civilization runs on words, Your Reverence. CivilizationĀ isĀ words. Which, on the whole, should not be too expensive. The world turns, Your Reverence, and we must spin with it...Once upon a time nations fought like great grunting beasts in a swamp. Ankh-Morpork ruled a large part of that swamp because it had the best claws. But today gold has taken the place of steel and, my goodness, the Ankh-Morpork dollar seems to be the currency of choice. Tomorrow...perhaps the weaponry will be just words. The most words, the quickest words, the last words.
