"I mean exactly that," Mahmoud insisted, "when it applies to any verbalizing race.  Such as ourselves.  Such as the Martians - even more highly verbalized than we are.  A verbalizing race has words for every old concept... and creates new words or new definitions for old words whenever a new concept comes along.  Always!  A nervous system that is able to verbalize cannot avoid verbalizing; it's automatic.  If the Martians know what 'war' is, then they have a word for it."
