sword is the crux of the matter. What did the alien say about the sword? 'It is defective.' It is defective, Bob. Not as an instrument of death. It will kill a man or injure him well enough. "But a sword—or any other instrument of force for that matter—is a terribly ineffectual tool. It was originally designed to act as a tool of social control. Did it—or any subsequent weapon of force—do a good job at that? "As long as man used swords, or gunpowder, or atom bombs, or hydrogen bombs, he was doomed to a fearful anarchy of unsolved problems and dreadful immaturity. "No, the sword is not useful. To fix it—to 'correct that which renders it not useful'—meant to make it something else. Now what in the hell did that mean? What can you do with a sword?" "You mean besides cut a man in two with it," said Mills. "Yes, what can you do with it besides use it as a weapon? Here our street-corner friend referred me to the right place: The bible! "They shall beat their swords into ploughshares, and their spears into pruning-hooks; nation shall not lift up sword against nation, neither shall they learn war any more. "The aliens just wanted to know if we meant what we said." "Do we?" "We better. It's going to take a hell of a lot more than a silly ploughshare to convince those babies on that ship. But there's more to it than that. The ability of a culture finally to pound all of its swords—its intellectual ones as well as its steel ones—into ploughshares must be some kind of least common denominator for cultures that are headed for the stars."
