They seemed to declare all the old constants unreliable. They brought so many novelties, of such magnitude, to so many fields of endeavor, that a characteristic national quandary has arrived in dozens of industries, professions, and sciences. The quandary is anchored to this simple question: Will any of the old rules endure?
